OAuth Class

Properties   Methods   Events   Config Settings   Errors  

The OAuth class is used to authorize a client and provide an authorization string used in future requests.

Syntax

class inpay.OAuth

Remarks

The OAuth class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over SSL/TLS the on_ssl_server_authentication event allows you to check the server identity and other security attributes. The on_ssl_status event provides information about the SSL handshake. Additional SSL related settings are also supported via the config method.

The OAuth class provides an easy way to obtain an authorization string for future requests to a service. The class implements an OAuth 2.0 client.

To begin using the class, first register your application with the service you want to use. During this process, obtain a client_id and client_secret as well as the server_auth_url and server_token_url for the authorization server. Then set client_profile to the client profile that best describes your situation and call get_authorization.

The following client profiles are currently supported by the class:

• Application (desktop application)
• Web (server-side application, such as a website)
• Device (an application without browser access, such as a game console)
• Mobile (phone or tablet application)
• JWT (server-to-server authentication using a JWT Bearer Token, such as Google service account authentication)

Application Profile

The Application profile is applicable to applications that are run directly by the user. For instance, a Windows form application would use the Application profile. To authorize your application (client) using the Application profile, use the following steps:

First, set client_profile to ocpApplication. This defines the profile the class will use. Set the client_id, client_secret, server_auth_url, and server_token_url to the values you obtained when registering your application.

Second, call get_authorization to begin the authorization process. When get_authorization is called, the class will build the URL to which the user will be directed and fire the on_launch_browser event. The class will then launch the browser using the command and URL shown in the on_launch_browser event and await the response. The duration for which the class will wait for a response is defined by BrowserResponseTimeout.

Third, the user will interact with the browser to authenticate and grant access to the connecting application. The user will then be redirected back to an embedded web server that was automatically started when get_authorization was called. At this time, the on_return_url event will fire. This event provides an opportunity to provide a custom response to your user that they will see in their browser.

Fourth, the class will then automatically exchange the grant that was returned by the authorization server for the access token using the HTTP endpoint specified in server_token_url.

The authorization is now complete and the get_authorization method will return the authorization string. The authorization string can then be used with any of our components by simply setting the returned value to the authorization property before making a request.

The following is a simple example: component.ClientId = "CLIENT_ID"; component.ClientSecret = "CLIENT_ID"; component.ServerAuthURL = "https://accounts.google.com/o/oauth2/auth"; component.ServerTokenURL = "https://accounts.google.com/o/oauth2/token"; HTTP.Authorization = component.GetAuthorization(); HTTP.Get("https://www.googleapis.com/oauth2/v1/userinfo");

Web Profile

The Web profile is applicable to applications that are run on the server side when the user uses the application from a web browser. To authorize your application (client) using this profile, use the following steps:

First, set client_profile to ocpWeb. This defines the profile the component will use. Set the client_id, client_secret, server_auth_url, and server_token_url to the values you obtained when registering your application. Set return_url to the page on your site that will be the endpoint the user is redirected back to after authentication.

Second, call get_authorization_url. This will return a URL to which the user should be redirected. Redirect the user to this URL.

Third, after the user authenticates and is returned to the page on your site specified by return_url, parse the "code" query string parameter from the incoming request to get the authorization code from the authorization server. Then, set authorization_code property to the parsed value.

Fourth, after authorization_code is set, call get_authorization to exchange the code specified in authorization_code for a token from the server specified by server_token_url. get_authorization will then return the authorization string. The authorization string can be used with any of our components by simply setting the returned value to the authorization property before making a request.

Device Profile

The Device profile is applicable to applications that are run on devices for which a web browser cannot be used. For example, a game console would use the Device profile. To authorize your application (client) using the device client profile use the following steps:

First, set client_profile to ocpDevice. This defines the profile the class will use. Set the client_id, client_secret, server_auth_url, and server_token_url to the values you obtained when registering your application. Do not set return_url.

Second, call get_authorization_url. The class will automatically make a request to server_auth_url to obtain a user code for the device. The get_authorization_url method will return the URL your user must visit from another device or computer that has web browser support. The get_authorization_url method will also populate DeviceUserCode. This device user code must be provided to the user. The user will enter the code at the URL returned by get_authorization_url.

Third, at this time, call get_authorization. The class will begin polling the server specified in server_token_url. The polling interval is specified (in seconds) by the PollingInterval setting.

Fourth, after the user has authenticated, the get_authorization method will return the authorization string. To use the authorization string with any of our components, simply pass this value to the authorization property before making the request.

Mobile Profile

The Mobile profile is applicable to applications that are run on devices for which a web browser can be used. For instance, a mobile phone or tablet would use the Mobile profile. The behavior when using this profile is very similar to the Application profile. The only difference between the Mobile and Application profiles is the way the browser is launched. When set to the Mobile profile, the on_launch_browser event will fire but the class will not attempt to launch the browser automatically. The browser must be launched manually from code. This behavior is the only difference between the Mobile and Application profiles. Please read the steps for the Application profile for a more detailed look at the process.

JWT Bearer Token (Server-to-Server) Profile

The JWT (JSON Web Token) Bearer Token profile is available for server-to-server authentication. For instance this may be used by web applications to access a Google service. In this case, the application will access data on behalf of the service account, not the end user. End-user interaction is not required.

First, specify authorization_scope server_token_url and JWTServiceProvider.

Second, specify JWT-specific values. The use of the JWT profile also requires additional configuration settings to be specified, including a certificate with private key used to sign the JWT. Either specify the JWTJSONKey configuration setting, which will parse the necessary information automatically, or manually specify the following configuration settings:

• JWTIssuer (required)
• JWTAudience (required)
• JWTCertStoreType (required)
• JWTCertStore (required)
• JWTCertStorePassword (required)
• JWTCertSubject (required)
• JWTSubject
• JWTValidityTime
• JWTSignatureAlgorithm

Example 1. Google: oauth.AuthorizationScope = "https://www.googleapis.com/auth/analytics"; oauth.ServerTokenURL = "https://www.googleapis.com/oauth2/v3/token"; oauth.ClientProfile = OauthClientProfiles.ocpJWT; oauth.Config("JWTServiceProvider=0"); oauth.Config("JWTIssuer=CLIENT_ID"); oauth.Config("JWTAudience=https://www.googleapis.com/oauth2/v3/token"); oauth.Config("JWTCertStoreType=2"); oauth.Config("JWTCertStore=C:\\MyCertificate.p12"); oauth.Config("JWTCertStorePassword=password"); oauth.Config("JWTCertSubject=*"); oauth.Config("JWTValidityTime=5400"); //in seconds string authStr = oauth.GetAuthorization();

Example 2. Microsoft: oauth.ClientId = "Client_Id"; oauth.ClientProfile = OauthClientProfiles.ocpJWT; oauth.AuthorizationScope = "https://graph.microsoft.com/.default"; oauth.ServerTokenURL = "https://login.microsoftonline.com/" + tenant_id + "/oauth2/V2.0/token"; oauth.Config("JWTServiceProvider=1"); oauth.Config("JWTIssuer=" + CLIENT_ID); oauth.Config("JWTSubject=" + CLIENT_ID); oauth.Config("JWTCertStoreType=2"); oauth.Config("JWTCertStore=C:\\MyCertificate.p12"); oauth.Config("JWTCertStorePassword=password"); oauth.Config("JWTCertSubject=*"); oauth.Config("JWTValidityTime=3600"); oauth.Config("JWTAudience=https://login.microsoftonline.com/"+ tenant_id + "/oauth2/V2.0/token"); string authStr = oauth.GetAuthorization();

Custom Responses

When using a profile that makes use of the embedded web server, the response that is displayed to the user on success of failure may be customized to include a variety of product- and company-specific information. The following section is applicable only when the embedded web server is used, for instance, when client_profile is set to ocpApplication.

By default, the class will display a formatted result message indicating whether the authorization succeeded or failed. The following optional settings control the text of the message as well as product images, company logos, and links for help or licensing terms that can be displayed to the user.

Alternatively, for complete control, set the WebServerResponse and WebServerFailedResponse settings to the full HTML to be displayed to the user.

Config Settings

The following is a list of config settings for the class with short descriptions. Click on the links for further details.

access_token Property

This property includes the access token returned by the authorization server.

Syntax

def get_access_token() -> str: ...
def set_access_token(value: str) -> None: ...

access_token = property(get_access_token, set_access_token)

Default Value

""

Remarks

This property will be populated with the access token returned by the authorization server after a call to get_authorization. This will be the raw access token, whereas the return value from the get_authorization method will also include the required data so that it can be passed directly to the Authorization property of other components or added as the value of the authorization header in another client implementation.

access_token_exp Property

This property includes the lifetime of the access token.

Syntax

def get_access_token_exp() -> int: ...

access_token_exp = property(get_access_token_exp, None)

Default Value

0

Remarks

This setting holds the lifetime of the access token in seconds. For instance the value 3600 indicates that the token will expire in one hour from the time it was generated.

This property is read-only.

authorization_code Property

This property includes the authorization code that is exchanged for an access token.

Syntax

def get_authorization_code() -> str: ...
def set_authorization_code(value: str) -> None: ...

authorization_code = property(get_authorization_code, set_authorization_code)

Default Value

""

Remarks

This property is used with the AuthorizationCode grant_type. When client_profile is set to ocpApplication (Application flow), this property will be informational only, as the get_authorization method will automatically exchange this code for a token with the authorization server specified in server_token_url.

When client_profile is set to ocpWeb (Web flow), this property needs to be set to the authorization code returned from the authorization server. Typically, this value is parsed when the service redirects the user back to your website. See client_profile for more information.

If this property is set before calling get_authorization, the class will not make a request to the authorization sever and instead will attempt to exchange the code with the authorization server for an access token.

authorization_scope Property

This property includes the scope request or response parameter used during authorization.

Syntax

def get_authorization_scope() -> str: ...
def set_authorization_scope(value: str) -> None: ...

authorization_scope = property(get_authorization_scope, set_authorization_scope)

Default Value

""

Remarks

If the scope is not set, the authorization server will use the default access scope for your application as determined by the server. To request a specific access scope, set this property to a space-separated list of strings as defined by the authorization server.

After calling get_authorization, this property will be updated with the scope sent in the response from the server and will indicate the scope that was actually granted.

client_id Property

This property includes the Id of the client assigned when registering the application.

Syntax

def get_client_id() -> str: ...
def set_client_id(value: str) -> None: ...

client_id = property(get_client_id, set_client_id)

Default Value

""

Remarks

This property holds the Id of the client that was assigned when initially registering the application with the authorization server. This value must be specified before calling get_authorization or get_authorization_url.

client_profile Property

This property includes the type of client that is requesting authorization.

Syntax

def get_client_profile() -> int: ...
def set_client_profile(value: int) -> None: ...

client_profile = property(get_client_profile, set_client_profile)

Default Value

0

Remarks

This defines the type of client that will be requesting authorization. Set this before calling get_authorization to inform the class to act accordingly. Possible values are as follows:

Application Profile

The Application profile is applicable to applications that are run directly by the user. For instance, a Windows form application would use the Application profile. To authorize your application (client) using the Application profile, use the following steps:

First, set client_profile to ocpApplication. This defines the profile the class will use. Set the client_id, client_secret, server_auth_url, and server_token_url to the values you obtained when registering your application.

Second, call get_authorization to begin the authorization process. When get_authorization is called, the class will build the URL to which the user will be directed and fire the on_launch_browser event. The class will then launch the browser using the command and URL shown in the on_launch_browser event and await the response. The duration for which the class will wait for a response is defined by BrowserResponseTimeout.

Third, the user will interact with the browser to authenticate and grant access to the connecting application. The user will then be redirected back to an embedded web server that was automatically started when get_authorization was called. At this time, the on_return_url event will fire. This event provides an opportunity to provide a custom response to your user that they will see in their browser.

Fourth, the class will then automatically exchange the grant that was returned by the authorization server for the access token using the HTTP endpoint specified in server_token_url.

The authorization is now complete and the get_authorization method will return the authorization string. The authorization string can then be used with any of our components by simply setting the returned value to the authorization property before making a request.

The following is a simple example: component.ClientId = "CLIENT_ID"; component.ClientSecret = "CLIENT_ID"; component.ServerAuthURL = "https://accounts.google.com/o/oauth2/auth"; component.ServerTokenURL = "https://accounts.google.com/o/oauth2/token"; HTTP.Authorization = component.GetAuthorization(); HTTP.Get("https://www.googleapis.com/oauth2/v1/userinfo");

Web Profile

The Web profile is applicable to applications that are run on the server side when the user uses the application from a web browser. To authorize your application (client) using this profile, use the following steps:

First, set client_profile to ocpWeb. This defines the profile the component will use. Set the client_id, client_secret, server_auth_url, and server_token_url to the values you obtained when registering your application. Set return_url to the page on your site that will be the endpoint the user is redirected back to after authentication.

Second, call get_authorization_url. This will return a URL to which the user should be redirected. Redirect the user to this URL.

Third, after the user authenticates and is returned to the page on your site specified by return_url, parse the "code" query string parameter from the incoming request to get the authorization code from the authorization server. Then, set authorization_code property to the parsed value.

Fourth, after authorization_code is set, call get_authorization to exchange the code specified in authorization_code for a token from the server specified by server_token_url. get_authorization will then return the authorization string. The authorization string can be used with any of our components by simply setting the returned value to the authorization property before making a request.

Device Profile

The Device profile is applicable to applications that are run on devices for which a web browser cannot be used. For example, a game console would use the Device profile. To authorize your application (client) using the device client profile use the following steps:

First, set client_profile to ocpDevice. This defines the profile the class will use. Set the client_id, client_secret, server_auth_url, and server_token_url to the values you obtained when registering your application. Do not set return_url.

Second, call get_authorization_url. The class will automatically make a request to server_auth_url to obtain a user code for the device. The get_authorization_url method will return the URL your user must visit from another device or computer that has web browser support. The get_authorization_url method will also populate DeviceUserCode. This device user code must be provided to the user. The user will enter the code at the URL returned by get_authorization_url.

Third, at this time, call get_authorization. The class will begin polling the server specified in server_token_url. The polling interval is specified (in seconds) by the PollingInterval setting.

Fourth, after the user has authenticated, the get_authorization method will return the authorization string. To use the authorization string with any of our components, simply pass this value to the authorization property before making the request.

Mobile Profile

The Mobile profile is applicable to applications that are run on devices for which a web browser can be used. For instance, a mobile phone or tablet would use the Mobile profile. The behavior when using this profile is very similar to the Application profile. The only difference between the Mobile and Application profiles is the way the browser is launched. When set to the Mobile profile, the on_launch_browser event will fire but the class will not attempt to launch the browser automatically. The browser must be launched manually from code. This behavior is the only difference between the Mobile and Application profiles. Please read the steps for the Application profile for a more detailed look at the process.

JWT Bearer Token (Server-to-Server) Profile

The JWT (JSON Web Token) Bearer Token profile is available for server-to-server authentication. For instance this may be used by web applications to access a Google service. In this case, the application will access data on behalf of the service account, not the end user. End-user interaction is not required.

First, specify authorization_scope server_token_url and JWTServiceProvider.

Second, specify JWT-specific values. The use of the JWT profile also requires additional configuration settings to be specified, including a certificate with private key used to sign the JWT.

Default Value

""

Remarks

This property contains a user name if authentication is to be used connecting through a firewall. If the firewall_host is specified, this property and firewall_password properties are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.

follow_redirects Property

This property determines what happens when the server issues a redirect.

Syntax

def get_follow_redirects() -> int: ...
def set_follow_redirects(value: int) -> None: ...

follow_redirects = property(get_follow_redirects, set_follow_redirects)

Default Value

0

Remarks

This property determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new url for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new url is retrieved automatically only if the url_scheme is the same; otherwise, the class fails with an error.

Note: Following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, user and password are also reset to empty. If, however, this property is set to frAlways (1), the same credentials are used to connect to the new server.

A on_redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the on_redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the class fails with an error instead.

grant_type Property

This property includes the OAuth grant type used to acquire an OAuth access token.

Syntax

def get_grant_type() -> int: ...
def set_grant_type(value: int) -> None: ...

grant_type = property(get_grant_type, set_grant_type)

Default Value

0

Remarks

This setting specifies the type of grant to obtain. In most cases the Authorization Code grant type (default) is used, so it is typically not necessary to change this. The supported values are:

For all grant types listed set client_profile to Application.

The Authorization Code grant is the most commonly used grant type. It follows the flow described for the Application Client Profile section in the OAuth introduction page.

Implicit grants are similar to Authorization Code, except that a Bearer token is returned directly from the authorization server without requiring a second step to exchange a code for a bearer token. To use this grant type set:

• client_id
• client_secret
• server_auth_url

The Resource Owner Password Credentials grant type may be used to authenticate on behalf of a resource owner with the owner's credentials. Authentication is performed directly and the user is not prompted to authenticate the application. To use this grant type set:

• PasswordGrantUsername to the username of the resource owner
• client_secret to the password of the resource owner
• client_id optional, set to the client id for the resource
• server_token_url

The Client Credentials grant type is typically used for server-to-server authentication. The client authenticates directly to the authentication server and receives a token without any user interaction. To use this grant type set:

• client_id
• client_secret
• server_token_url

The AdminConsent grant type is used when setting up application permissions for apps that authenticate to Microsoft. To use this grant type set:

• client_id

If the Admin consents to the scopes, the tenant ID can be accessed through the Microsoft365AdminConsentTenant configuration and is often needed for authenticating a client later (eg. Client Credentials Grant Flow). Once the Admin consents once, they typically will not need to go through the process again unless the scopes of the application change.

If the Admin does not consent to the scopes, the error message can be found in the Microsoft365AdminConsentError configuration setting and the error description can be found in the Microsoft365AdminConsentErrorDesc configuration setting.

idle Property

The current status of the class.

Syntax

def get_idle() -> bool: ...

idle = property(get_idle, None)

Default Value

TRUE

Remarks

idle will be False if the component is currently busy (communicating and/or waiting for an answer), and True at all other times.

This property is read-only.

local_host Property

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

def get_local_host() -> str: ...
def set_local_host(value: str) -> None: ...

local_host = property(get_local_host, set_local_host)

Default Value

""

Remarks

The local_host property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the local_host property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: local_host is not persistent. You must always set it in code, and never in the property window.

other_headers Property

This property includes other headers as determined by the user (optional).

Syntax

def get_other_headers() -> str: ...
def set_other_headers(value: str) -> None: ...

other_headers = property(get_other_headers, set_other_headers)

Default Value

""

Remarks

This property can be set to a string of headers to be appended to the HTTP request headers created from other properties like content_type and from_.

The headers must follow the format Header: Value as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for extending the functionality of the class beyond what is provided.

param_count Property

The number of records in the Param arrays.

Syntax

def get_param_count() -> int: ...
def set_param_count(value: int) -> None: ...

param_count = property(get_param_count, set_param_count)

Default Value

0

Remarks

This property controls the size of the following arrays:

• param_name

proxy_auth_scheme Property

This property is used to tell the class which type of authorization to perform when connecting to the proxy.

Syntax

def get_proxy_auth_scheme() -> int: ...
def set_proxy_auth_scheme(value: int) -> None: ...

proxy_auth_scheme = property(get_proxy_auth_scheme, set_proxy_auth_scheme)

Default Value

0

Remarks

This property is used to tell the class which type of authorization to perform when connecting to the proxy. This is used only when the proxy_user and proxy_password properties are set.

proxy_auth_scheme should be set to authNone (3) when no authentication is expected.

By default, proxy_auth_scheme is authBasic (0), and if the proxy_user and proxy_password properties are set, the component will attempt basic authentication.

If proxy_auth_scheme is set to authDigest (1), digest authentication will be attempted instead.

If proxy_auth_scheme is set to authProprietary (2), then the authorization token will not be generated by the class. Look at the configuration file for the class being used to find more information about manually setting this token.

If proxy_auth_scheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this property will clear the values of proxy_user and proxy_password.

If proxy_auth_scheme is set to Basic Authentication, the proxy_user and proxy_password are Base64 encoded and the proxy authentication token will be generated in the form Basic [encoded-user-password].

If proxy_auth_scheme is set to Digest Authentication, the proxy_user and proxy_password properties are used to respond to the Digest Authentication challenge from the server.

If proxy_auth_scheme is set to NTLM Authentication, the proxy_user and proxy_password properties are used to authenticate through NTLM negotiation.

refresh_token Property

This property specifies the refresh token received from or sent to the authorization server.

Syntax

def get_refresh_token() -> str: ...
def set_refresh_token(value: str) -> None: ...

refresh_token = property(get_refresh_token, set_refresh_token)

Default Value

""

Remarks

When get_authorization is called, if the authorization server returns a refresh token along with the access token, this property will hold the refresh token. Save this value for later use.

When your access token expires, set this property to the corresponding refresh token. Then call get_authorization, and the class will use this token to retrieve a new access token. The new authorization string will be returned by the get_authorization method. No user interaction is required when refreshing an access token.

return_url Property

This property includes the URL where the user (browser) returns after authenticating.

Syntax

def get_return_url() -> str: ...
def set_return_url(value: str) -> None: ...

return_url = property(get_return_url, set_return_url)

Default Value

""

Remarks

When client_profile is set to ocpApplication, this will be automatically set to the address of the local embedded web server. In that case, this property can be inspected to determine the URL where the user will be redirected, but it does not need to be set.

When calling get_authorization_url, which is common when client_profile is set to ocpWeb, set this property to the URL on your server where the user will be redirected after authenticating with the authorization server.

Default Value

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

ssl_cert_subject Property

This is the subject of the certificate used for client authentication.

Syntax

def get_ssl_cert_subject() -> str: ...
def set_ssl_cert_subject(value: str) -> None: ...

ssl_cert_subject = property(get_ssl_cert_subject, set_ssl_cert_subject)

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properites are set. When this property is set, a search is performed in the current certificate store certificate with matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

If a field value contains a comma it must be quoted.

ssl_provider Property

This specifies the SSL/TLS implementation to use.

Syntax

def get_ssl_provider() -> int: ...
def set_ssl_provider(value: int) -> None: ...

ssl_provider = property(get_ssl_provider, set_ssl_provider)

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

Additional Notes

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

ssl_server_cert_encoded Property

This is the certificate (PEM/base64 encoded).

Syntax

def get_ssl_server_cert_encoded() -> bytes: ...

ssl_server_cert_encoded = property(get_ssl_server_cert_encoded, None)

Default Value

""

Remarks

When ssl_server_cert_encoded is set, a search is initiated in the current ssl_server_cert_store for the private key of the certificate. If the key is found, ssl_server_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_server_cert_subject is set to an empty string.

This property is read-only.

timeout Property

A timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

Default Value

60

Remarks

If the timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use do_events to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If timeout expires, and the operation is not yet complete, the class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by timeout seconds when any amount of data is successfully sent or received.

The default value for the timeout property is 60 seconds.

transferred_data Property

This property includes the contents of the last response from the server.

Syntax

def get_transferred_data() -> bytes: ...

transferred_data = property(get_transferred_data, None)

Default Value

add_cookie Method

This method adds a cookie and the corresponding value to the outgoing request headers.

Syntax

def add_cookie(cookie_name: str, cookie_value: str) -> None: ...

Remarks

This property adds a cookie and the corresponding value to the outgoing request headers. Please refer to the cookies property for more information on cookies and how they are managed.

add_param Method

This method adds a name-value pair to the query string parameters of outgoing request.

Syntax

def add_param(param_name: str, param_value: str) -> None: ...

Remarks

This method can be used to add query string parameters to the outgoing request. One common use for this method would be to add the state parameter to the request, which can be used when the client_profile is ocpWeb to add user-defined data. The authorization server will include the state parameter in the response and will be available in the post back to your server, which will allow you to maintain state in your application.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

do_events Method

Processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

get_authorization Method

This method gets the authorization string required to access the protected resource.

Syntax

def get_authorization() -> str: ...

Remarks

This method performs several operations automatically depending on the value of client_profile. Please see the introduction section for the OAuth class for a detailed overview of the typical scenarios.

After authorization is completed, this method will return the authorization string, which can be passed directly to the authorization property of any other component. This can also be passed as the value of the HTTP authorization header to other implementations that access the protected resource as well.

The access_token property should be cleared before calling this method.

get_authorization_url Method

This method builds and returns the URL to which the user should be redirected for authorization.

Syntax

def get_authorization_url() -> str: ...

Remarks

When this method is called, the class will return the URL used for authorization. The class will not make any connections, but instead it will return the URL to you so that you may redirect the user to this location. This is useful when client_profile is set to ocpWeb. Before calling this method, set the following:

• client_id
• client_secret
• return_url
• authorization_scope (optional)

get_param Method

This method gets a specific parameter from a query string.

Syntax

def get_param(param_name: str) -> str: ...

Remarks

This method can be used to get a specific parameter from a query string.

For example, when using the ocpApplication profile, this method can be used in the on_return_url event to query the parameters that are returned from the authorization server. Then, it can be called after get_authorization completes to query the parameters that the token server responded with.

string authorizationString = oauth.GetAuthorization(); string stateValue = oauth.GetParam("state");

interrupt Method

Interrupt the current method.

Syntax

def interrupt() -> None: ...

Remarks

If there is no method in progress, interrupt simply returns, doing nothing.

reset Method

Reset the class.

Syntax

def reset() -> None: ...

Remarks

This method will reset the class's properties to their default values.

start_web_server Method

This method starts the embedded web server.

Syntax

def start_web_server() -> None: ...

Remarks

This method starts the embedded web server. This method can be used to manually start the embedded web server. Under normal circumstances, this is not needed as the component will automatically start and stop the web server when get_authorization is called. You may decide, however, to start the web server manually before calling get_authorization. When called, this method will also populate return_url with the address of the embedded server.

stop_web_server Method

This method stops the embedded web server.

Syntax

def stop_web_server() -> None: ...

Remarks

This method stops the embedded web server. Under normal circumstances, the web server will be stopped automatically during the authorization process when get_authorization is called. If ReUseWebServer is set to True, the server will not be automatically stopped, and this method must be called to stop the embedded web server.

on_connected Event

This event is fired immediately after a connection completes (or fails).

Syntax

class OAuthConnectedEventParams(object):
  @property
  def status_code() -> int: ...

  @property
  def description() -> str: ...

# In class OAuth:
@property
def on_connected() -> Callable[[OAuthConnectedEventParams], None]: ...
@on_connected.setter
def on_connected(event_hook: Callable[[OAuthConnectedEventParams], None]) -> None: ...

Remarks

If the connection is made normally, StatusCode is 0 and Description is "OK".

If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

Please refer to the Error Codes section for more information.

on_connection_status Event

This event is fired to indicate changes in the connection state.

Syntax

class OAuthConnectionStatusEventParams(object):
  @property
  def connection_event() -> str: ...

  @property
  def status_code() -> int: ...

  @property
  def description() -> str: ...

# In class OAuth:
@property
def on_connection_status() -> Callable[[OAuthConnectionStatusEventParams], None]: ...
@on_connection_status.setter
def on_connection_status(event_hook: Callable[[OAuthConnectionStatusEventParams], None]) -> None: ...

Remarks

The on_connection_status event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.

The ConnectionEvent parameter indicates the type of connection event. Values may include the following:

StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

on_disconnected Event

This event is fired when a connection is closed.

Syntax

class OAuthDisconnectedEventParams(object):
  @property
  def status_code() -> int: ...

  @property
  def description() -> str: ...

# In class OAuth:
@property
def on_disconnected() -> Callable[[OAuthDisconnectedEventParams], None]: ...
@on_disconnected.setter
def on_disconnected(event_hook: Callable[[OAuthDisconnectedEventParams], None]) -> None: ...

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.

on_end_transfer Event

This event is fired when a document finishes transferring.

Syntax

class OAuthEndTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class OAuth:
@property
def on_end_transfer() -> Callable[[OAuthEndTransferEventParams], None]: ...
@on_end_transfer.setter
def on_end_transfer(event_hook: Callable[[OAuthEndTransferEventParams], None]) -> None: ...

Remarks

The on_end_transfer event is fired first when the client finishes sending data to the server (in a POST or PUT request) and then when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_error Event

Information about errors during data delivery.

Syntax

class OAuthErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class OAuth:
@property
def on_error() -> Callable[[OAuthErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[OAuthErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

on_header Event

This event is fired every time a header line comes in.

Syntax

class OAuthHeaderEventParams(object):
  @property
  def field() -> str: ...

  @property
  def value() -> str: ...

# In class OAuth:
@property
def on_header() -> Callable[[OAuthHeaderEventParams], None]: ...
@on_header.setter
def on_header(event_hook: Callable[[OAuthHeaderEventParams], None]) -> None: ...

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

on_launch_browser Event

This event fires before launching a browser with the authorization URL.

Syntax

class OAuthLaunchBrowserEventParams(object):
  @property
  def url() -> str: ...
  @url.setter
  def url(value) -> None: ...

  @property
  def command() -> str: ...
  @command.setter
  def command(value) -> None: ...

# In class OAuth:
@property
def on_launch_browser() -> Callable[[OAuthLaunchBrowserEventParams], None]: ...
@on_launch_browser.setter
def on_launch_browser(event_hook: Callable[[OAuthLaunchBrowserEventParams], None]) -> None: ...

Remarks

When the client_profile property is set to ocpApplication and get_authorization is called, the class will fire this event with the Command, which will be executed by the class. The URL parameter will be the authorization URL that the user will be directed to authenticate.

Within this event, you may override the current value of either Command or URL and provide your own value. If Command is set to an empty string, the class will not attempt to launch the browser and instead you will be responsible for directing the user to the authorization URL specified by the URL parameter.

In Windows, ShellExecute is used to execute Command, which limits the verbs available for use in Command to:

• edit
• explore
• find
• open
• print

on_log Event

This event fires once for each log message.

Syntax

class OAuthLogEventParams(object):
  @property
  def log_level() -> int: ...

  @property
  def message() -> str: ...

  @property
  def log_type() -> str: ...

# In class OAuth:
@property
def on_log() -> Callable[[OAuthLogEventParams], None]: ...
@on_log.setter
def on_log(event_hook: Callable[[OAuthLogEventParams], None]) -> None: ...

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"
• "FirewallResponse"

on_redirect Event

This event is fired when a redirection is received from the server.

Syntax

class OAuthRedirectEventParams(object):
  @property
  def location() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class OAuth:
@property
def on_redirect() -> Callable[[OAuthRedirectEventParams], None]: ...
@on_redirect.setter
def on_redirect(event_hook: Callable[[OAuthRedirectEventParams], None]) -> None: ...

Remarks

This event is fired in cases in which the client can decide whether or not to continue with the redirection process. The Accept parameter is always True by default, but if you do not want to follow the redirection, Accept may be set to False, in which case the class fails with an error. Location is the location to which the client is being redirected. Further control over redirection is provided in the follow_redirects property.

on_return_url Event

This event fires when the user is redirected to the embedded web server.

Syntax

class OAuthReturnURLEventParams(object):
  @property
  def url_path() -> str: ...

  @property
  def query_string() -> str: ...

  @property
  def response_headers() -> str: ...
  @response_headers.setter
  def response_headers(value) -> None: ...

  @property
  def response_body() -> str: ...
  @response_body.setter
  def response_body(value) -> None: ...

# In class OAuth:
@property
def on_return_url() -> Callable[[OAuthReturnURLEventParams], None]: ...
@on_return_url.setter
def on_return_url(event_hook: Callable[[OAuthReturnURLEventParams], None]) -> None: ...

Remarks

When client_profile is set to ocpApplication and the embedded web server is used (default), this event will fire when the user is redirected from the authorization server back to the local embedded web server. The event provides an opportunity to set the ResponseHeaders and ResponseBody and to provide a custom response that the user will see in their browser.

URLPath and QueryString are informational parameters that show the values sent by the authorization server.

Additionally, the Params* properties will be populated. This allows the get_param method to be used to get a specific parameter returned from the authorization server when used within this event.

on_set_cookie Event

This event is fired for every cookie set by the server.

Syntax

class OAuthSetCookieEventParams(object):
  @property
  def name() -> str: ...

  @property
  def value() -> str: ...

  @property
  def expires() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def path() -> str: ...

  @property
  def secure() -> bool: ...

# In class OAuth:
@property
def on_set_cookie() -> Callable[[OAuthSetCookieEventParams], None]: ...
@on_set_cookie.setter
def on_set_cookie(event_hook: Callable[[OAuthSetCookieEventParams], None]) -> None: ...

Remarks

The on_set_cookie event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (url_server) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (url_path) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class OAuthSSLServerAuthenticationEventParams(object):
  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class OAuth:
@property
def on_ssl_server_authentication() -> Callable[[OAuthSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[OAuthSSLServerAuthenticationEventParams], None]) -> None: ...

Remarks

This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

on_ssl_status Event

Shows the progress of the secure connection.

Syntax

class OAuthSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class OAuth:
@property
def on_ssl_status() -> Callable[[OAuthSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[OAuthSSLStatusEventParams], None]) -> None: ...

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

on_start_transfer Event

This event is fired when a document starts transferring (after the headers).

Syntax

class OAuthStartTransferEventParams(object):
  @property
  def direction() -> int: ...

# In class OAuth:
@property
def on_start_transfer() -> Callable[[OAuthStartTransferEventParams], None]: ...
@on_start_transfer.setter
def on_start_transfer(event_hook: Callable[[OAuthStartTransferEventParams], None]) -> None: ...

Remarks

The on_start_transfer event is fired first when the client starts sending data to the server (in a POST or PUT request) and then when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_status Event

This event is fired when the HTTP status line is received from the server.

Syntax

class OAuthStatusEventParams(object):
  @property
  def http_version() -> str: ...

  @property
  def status_code() -> int: ...

  @property
  def description() -> str: ...

# In class OAuth:
@property
def on_status() -> Callable[[OAuthStatusEventParams], None]: ...
@on_status.setter
def on_status(event_hook: Callable[[OAuthStatusEventParams], None]) -> None: ...

Remarks

HTTPVersion is a string containing the HTTP version string as returned from the server (e.g., "1.1").

StatusCode contains the HTTP status code (e.g., 200), and Description the associated message returned by the server (e.g., "OK").

on_transfer Event

This event is fired while a document transfers (delivers document).

Syntax

class OAuthTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def percent_done() -> int: ...

  @property
  def text() -> bytes: ...

# In class OAuth:
@property
def on_transfer() -> Callable[[OAuthTransferEventParams], None]: ...
@on_transfer.setter
def on_transfer(event_hook: Callable[[OAuthTransferEventParams], None]) -> None: ...

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
