OAuthAPI.GetOpenIDMetadata()
Get metadata from the Identity Provider for a service running on a Genero Application Server (GAS).
Syntax
FUNCTION GetOpenIDMetadata()
RETURNS OAuthAPI.OpenIDMetadataType
NULL
may be returned if metadata is not found.
Usage
Use the GetOpenIDMetadata()
function to retrieve metadata—such as the
registration endpoint, supported scopes, and user information endpoints—provided by the Genero
Identity Provider for accessing a secure RESTful web service. A request is made to obtain this
metadata, which is then stored in an OpenIDMetadataType
record.
If the service is not started behind the GAS, you should call the FetchOpenIDMetadata() function instead.
In case of error, a NULL
value will be returned.
