Question

创建服务帐户并授予域范围授权是否应该能够访问我的doamin中的所有课程和作业？我是域管理员并创建了服务帐户。但是，当我执行代码时，它不会返回任何结果。当我直接从“参考”页面运行相同的请求时，它会返回数据。

域范围委派要求您指定您希望代理的域用户。它也不适用于应用程序默认凭据（内置于AppEngine和Compute Engine服务的服务帐户），您需要在项目中手动创建SA。假设您正在使用您创建的SA（凭证文件），请尝试添加：

$user_to_impersonate = "admin@yourdomain.com";
$client->setSubject($user_to_impersonate);
