GetCertificate

L'exemple Java suivant montre comment utiliser l'GetCertificateopération.

L'opération récupère un certificat à partir de votre autorité de certification privée. L'ARN du certificat est renvoyé lorsque vous appelez l'IssueCertificateopération. Vous devez spécifier à la fois l'ARN de votre autorité de certification privée et l'ARN du certificat émis lors de l'appel de l'opération GetCertificate. Vous pouvez récupérer le certificat si son état est ISSUED. Vous pouvez appeler l'CreateCertificateAuthorityAuditReportopération pour créer un rapport contenant des informations sur tous les certificats émis et révoqués par votre autorité de certification privée.

Votre sortie doit être une chaîne de certificats similaire à la chaîne suivante pour l'autorité de certification et le certificat que vous avez spécifiés.

-----BEGIN CERTIFICATE----- base64-encoded certificate -----END CERTIFICATE-----

-----BEGIN CERTIFICATE----- base64-encoded certificate -----END CERTIFICATE-----
