java - 请求 MS Graph 访问令牌以在 AAD 中实现订阅用户更改

Question

我正在尝试使用 java 实现 msgraph 订阅。我有以下代码。我能够获取访问令牌，但无法使用 graphClient 并且对如何提供 notificationUrl 及其后端处理也有疑问。

尝试{

           final ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
                   .clientId(CLIENT_ID)
                   .clientSecret(CLIENT_SECRET)
                   .tenantId(TENANT)
                   .build();

           final GraphServiceClient graphClient =
                   GraphServiceClient
                           .builder()
                           .authenticationProvider( Some authprovider here goes here )
                           .buildClient();

           Subscription subscription = new Subscription();
           subscription.changeType = "created";
           subscription.notificationUrl = "http://localhost:4200/1/mynotification";
           subscription.resource = "/users";
           subscription.expirationDateTime = OffsetDateTimeSerializer.deserialize("2022-03-20T18:23:45.9356913Z");
           subscription.clientState = "secretClientValue";
           //   subscription.latestSupportedTlsVersion = "v1_2";

           Subscription graphresult = graphClient.subscriptions()
                   .buildRequest()
                   .post(subscription);
       
           System.out.println("graphresult :"+graphresult );
       } catch (Exception e) {
           e.printStackTrace();
           logger.info("\nException : "+e);
       }

我希望有一个人可以帮助我！这将是一个很大的帮助！

谢谢你的时间！
