Der bereitgestellte Code konzentriert sich auf die Generierung einer SAML-Assertion und die anschließende Signierung der Assertion mithilfe eines X.509-Zertifikats. Die Erstellung der SOAP-Nachricht ist nicht inbegriffen. Der Code setzt voraus, dass Sie bereits über eine XML-Nachricht mit einem Platzhalter für die SAML-Behauptung verfügen und dass der Nachrichtentext den Inhalt enthält, den Sie senden möchten.
Hier ist ein Beispiel dafür, wie Sie den von mir bereitgestellten Code kombinieren können der Code zum Erstellen der SOAP-Nachricht:
