java - GoogleJsonResponseException : 404 Not Found during getting user list of enterprise

Question

我正在使用 Google Play EMM API (lib google-api-services-androidenterprise-v1-rev8-1.20.0.jar) 编写简单的应用程序，该应用程序应生成用于自动安装设备策略 Controller (Android for Work) 的激活代码)在设备上。

HttpTransport sHttpTransport = GoogleNetHttpTransport.newTrustedTransport();
JsonFactory sJsonFactory = JacksonFactory.getDefaultInstance();

GoogleCredential credentials = new GoogleCredential.Builder().setTransport(sHttpTransport).setJsonFactory(sJsonFactory)
        .setServiceAccountId(MASTER_SERVICE_ACCOUNT_EMAIL)
        .setServiceAccountScopes(AndroidEnterpriseScopes.all())
        .setServiceAccountPrivateKeyFromP12File(new File(PRIVATE_KEY_P12_FILE_NAME))
        .build();

AndroidEnterprise sAndroidEnterprise = new AndroidEnterprise(sHttpTransport, sJsonFactory, credentials);

String userId = sAndroidEnterprise.users().list(enterpriseId, userEmail).execute()
            .getUser()
            .get(0)
            .getId();

String activationCode = sAndroidEnterprise.users().generateToken(enterpriseId, userId).execute().getToken();

问题是我在方法execute()中得到异常结果

String userId = sAndroidEnterprise.users().list(enterpriseId, userEmail).execute()

    "reason" : "notFound"
  } ],

    at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:469)

最有趣的是，如果我将不存在的电子邮件作为参数 userEmail，方法execute() 也不异常(exception)，当然方法getUser() 返回null。

如何修复此代码以成功获取用户 ID？对我来说，这看起来像是库或服务器的问题，但我希望我只是做错了什么。

请注意:我已成功注册客户并按照 https://developers.google.com/play/enterprise/samples 做好准备工作

您似乎正在使用 MSA 帐户进行身份验证来调用 users() 方法。尝试使用 ESA 帐户进行身份验证，即您在请求中提到的企业 ID。 (您需要为客户创建服务帐户才能进行身份验证)。问题将会得到解决。
