Beispiele

protected override SecurityToken GetTokenCore(TimeSpan timeout)

    // Create a SamlSecurityToken from the provided assertion
    SamlSecurityToken samlToken = new SamlSecurityToken(assertion);

    // Create a SecurityTokenSerializer that will be used to serialize the SamlSecurityToken

    // Create a memory stream to write the serialized token into
    // Use an initial size of 64Kb
    MemoryStream s = new MemoryStream(UInt16.MaxValue);

    // Create an XmlWriter over the stream
    XmlWriter xw = XmlWriter.Create(s);

    // Write the SamlSecurityToken into the stream
    ser.WriteToken(xw, samlToken);

    // Seek back to the beginning of the stream
    s.Seek(0, SeekOrigin.Begin);

    // Load the serialized token into a DOM
    XmlDocument dom = new XmlDocument();
    dom.Load(s);

    // Create a KeyIdentifierClause for the SamlSecurityToken
    SamlAssertionKeyIdentifierClause samlKeyIdentifierClause = samlToken.CreateKeyIdentifierClause<SamlAssertionKeyIdentifierClause>();

Hinweise

Wenn die GetTokenCore-Methode überschrieben wird und das an den Tokenparameter übergebene Sicherheitstoken nicht abgerufen werden kann, wird die SecurityTokenException-Ausnahme ausgelöst.

Die GetToken-Methode wird von der ClientCredentials-Klasse aufgerufen, wenn ein Client eine SOAP-Nachricht sendet und ein Sicherheitstoken erforderlich ist.

Die GetToken-Methode ruft die GetTokenCore-Methode auf.
