Python 域范围权限签名JWTAssertionCredentials访问被拒绝

我对SignedJwtAssertionCredentials有问题。 此帖子中已经报告了此问题： 但这个解决方案对我不起作用。 以下是我的代码：

SERVICE_ACCOUNT_EMAIL = 'xxx.apps.googleusercontent.com'
SERVICE_ACCOUNT_PEM_FILE_PATH = 'privatekey.pem'
SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly',
          'https://www.googleapis.com/auth/drive.readonly',
          'https://www.googleapis.com/auth/drive.file',
          'https://www.googleapis.com/auth/admin.directory.user']

def get_drive_service_for_user(user_email):
    f = file(SERVICE_ACCOUNT_PEM_FILE_PATH, 'rb')
    key = f.read()
    f.close()

    credentials = SignedJwtAssertionCredentials(
        SERVICE_ACCOUNT_EMAIL, 
        key,
        scope=SCOPES, 
        sub=user_email)
    http = httplib2.Http()
    http = credentials.authorize(http)

    return build('drive', 'v2', http=http)

这是日志：

AccessTokenRefreshError: access_denied

我按照此指南设置了所有域范围的授权：

感谢您的帮助

您确定您在管理第三方OAuth客户端访问中添加了所有这些作用域，并在云控制台上启用了这些API吗？我很抱歉现在才回答，显然这是一个域问题，在另一个域上运行相同的代码工作正常。不管怎样，谢谢你域问题是什么？
