使用Appengine Flex服务帐户访问Drive文件夹的权限不足

我编写了一个使用所有客户端/ sdks的应用程序正式记录。

credentials = GoogleCredentials \
    .get_application_default() \
    .create_scoped('https://www.googleapis.com/auth/drive')
drive = discovery.build(
    'drive',
    'v3',
    http=self.credentials.authorize(Http())
)
drive.files() \
    .get(fileId=file_id) \
    .execute()

通过面板生成的服务帐户在本地运行完美,但在部署应用程序时,AppEngine灵活环境中的服务帐户会出现问题。

我已经检查了权限,但它们都已设置完毕。问题可能是由于“使用此参数将无效...”消息,在尝试创建范围凭据时出现。

正如您在之前的评论中提到的那样,这是一个known issue。如araf...@google.com所述,灵活环境中的App Engine实例似乎将uderlying GCE VM的凭据视为应用程序默认凭据。

  

在此期间,根据Using OAuth 2.0 for Server to Server Applications,您可以使用手动创建的服务帐户导出为存储在应用中的JSON密钥。

对于受此问题影响或解决方法无效的任何人,请在said issue上发布任何相关信息。
