GetPolicy

Das folgende Java-Beispiel zeigt, wie die -GetPolicyOperation verwendet wird.

Die -Operation ruft die ressourcenbasierte Richtlinie ab, die einer privaten Zertifizierungsstelle zugeordnet ist. Eine ressourcenbasierte Richtlinie wird verwendet, um die kontoübergreifende gemeinsame Nutzung von Zertifizierungsstellen zu ermöglichen. Sie finden den ARN einer privaten Zertifizierungsstelle, indem Sie die ListCertificateAuthorities Aktion aufrufen.

Zu den zugehörigen API-Aktionen gehören PutPolicy und DeletePolicy.
