Question

我正在尝试使用服务帐户列出域中的用户。

 String userEmail = "name@yourdomain.com";

GoogleCredential credential = new GoogleCredential.Builder()
                .setTransport(httpTransport)
                .setJsonFactory(JSON_FACTORY)
                .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
                .setServiceAccountPrivateKey(k.getPrivate())
                .setServiceAccountScopes(SCOPES)
            //    .setServiceAccountUser(userEmail)
                .build();   

//Call directory API
Directory service = new Directory.Builder(httpTransport, JSON_FACTORY, credential)
          .setApplicationName(APPLICATION_NAME)
          .build();

        // List the users in your domain
        Users result = service.users().list()
               .setCustomer("my_customer")
               .setMaxResults(10)
               .setOrderBy("email")
               .execute();
       List<User> users = result.getUsers();
       if (users == null || users.size() == 0) {
           System.out.println("No users found.");
       } else {
           System.out.println("Users:");
           for (User user1 : users) {
               System.out.println(user1.getName().getFullName());
           }
       }

我已经通过遵循Quickstart使用Oauth客户端ID来完成此操作。但是我不想向用户显示授权屏幕。因此，我使用服务帐户来实现域范围的委派。

因此，我已经从documentation中获取了代码来使用服务帐户。我使用密钥库从.p12文件中获得了私钥。我遵循了这个answer（@ sdm的答案）。当我运行下面的程序时，它给了我下面的错误。

当我取消注释.setServiceAccountUser（userEmail）时，它会给我

线程“ main”中的异常 com.google.api.client.auth.oauth2.TokenResponseException：401 未经授权

我给了用户正确的电子邮件ID。

有人可以向我解释背后的原因是什么以及如何解决吗？

线程“主”中的com.google.api.client.googleapis.json.GoogleJsonResponseException异常：503服务不可用
