我想知道是否可以在本地dev_appserver.py上运行的脚本中使用remote_api_stub。
我已经成功地通过remote_api_stub从命令行运行的基本脚本连接到开发/生产数据存储区，所以我非常有信心app.yaml设置正确。
如果我想从本地开发服务器中找到User对象列表，我可以简单地设置存根以连接到本地服务器，然后像往常一样获取ndb模型。
DEV_HOSTNAME = 'localhost'
DEV_PORT = '54256'
DEV_SERVER = '%s:%s' % (DEV_HOSTNAME, DEV_PORT)
DEV_PATH = '/_ah/remote_api'
DEV_SECURE = False
remote_api_stub.ConfigureRemoteApiForOAuth(DEV_SERVER, DEV_PATH, secure=DEV_SECURE)
users = User.query()
# at this point users will contain data from the DEVELOPMENT server
如果我想从生产服务器中找到用户对象列表，我只需要更改一些路径
PROD_SERVER = 'myappid.appspot.com'
PROD_PATH = '/_ah/remote_api'
PROD_SECURE = True
remote_api_stub.ConfigureRemoteApiForOAuth(PROD_SERVER, PROD_PATH, secure=PROD_SECURE)
users = User.query()
# at this point users will contain data from the PRODUCTION server
这两项工作都按预期工作，并会返回正确的数据。
当我尝试在dev_appserver.py实例上实际运行的任何代码段内设置remote_api_sub时，问题就开始了。
例如，如果我尝试在任何基本请求处理程序上配置存根，我会遇到一些问题。
如果我使用remote_api_stub.ConfigureRemoteApiForOAuth，使用与以前相同的参数，我会收到NotSupportedOnThisPlatform错误

所以我继续寻找然后发现了这个非常相似的问题和答案：here
但是，看起来他们使用的是remote_api_stub.ConfigureRemoteApi而不是remote_api_stub.ConfigureRemoteApiForOAuth。
当我尝试使用
时remote_api_stub.ConfigureRemoteApi(app_id=None, path='/_ah/remote_api',
auth_func=lambda: ('myemail', 'mypass'),
servername='myappid.appspot.com')
我得到了

如果我尝试使用（自己设置app_id）
remote_api_stub.ConfigureRemoteApi(app_id=myappid, path='/_ah/remote_api',
auth_func=lambda: ('myemail', 'mypass'),
servername='myappid.appspot.com')
我得到了与之前相同的HTTP错误404
就不使用OAuth时使用的电子邮件和密码组合而言，我尝试过对应用程序拥有所有权的用户名/密码，但这似乎不起作用。
我必须使用密钥设置一个服务帐户，以便命令行ConfigureRemoveApiForOAuth工作。我想知道如何使用该电子邮件remote-api-service@myappid.iam.gserviceaccount.com，但我不确定密码是什么，所以我认为可能不正确。
我也尝试在appengine_config.py中设置remote_api_stub，而不是在各个处理程序中设置，所有问题都是一样的。
我也尝试过使用vm：true和app.yaml，但它似乎没有什么区别。
总结一下： 是否可以使用remote_api_stub从谷歌应用程序本身的代码连接到谷歌应用程序引擎数据库？我已经可以从应用程序的OUTSIDE访问数据存储了，但是在里面运行的任何代码似乎都不起作用。
