我可以使用google應用內的remote_api_stub連接到遠程/生產數據存儲嗎？

Question

我想知道是否可以在本地dev_appserver.py上運行的腳本中使用remote_api_stub。

我已經成功地通過從命令行運行的基本腳本通過remote_api_stub連接到開發/生產數據存儲，所以我非常有信心app.yaml設置正確。

如果我想從我的本地開發服務器中找到用戶對象列表，我可以簡單地設置存根以連接到本地服務器，然後像往常一樣獲取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 

如果我想找到從生產服務器的用戶對象的列表，我只需要改變某些路徑

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 

的這兩項工作的預期將返回我正確的數據。

當我嘗試在dev_appserver.py實例上實際運行的任何代碼段內設置remote_api_sub時，問題就開始了。

例如，如果我嘗試在任何基本的請求處理程序上配置存根，我遇到了一些問題。

如果我使用remote_api_stub.ConfigureRemoteApiForOAuth，像以前一樣使用相同的參數，可以我得到一個錯誤NotSupportedOnThisPlatform

所以我繼續尋找，然後發現了這個非常類似的問題和答案：here

然而，看起來他們使用的是remote_api_stub.ConfigureRemoteApi而不是remote_api_stub.ConfigureRemoteApiForOAuth。

當我嘗試使用

remote_api_stub.ConfigureRemoteApi(app_id=None, path='/_ah/remote_api', 
            auth_func=lambda: ('myemail', 'mypass'), 
            servername='myappid.appspot.com') 

我得到

如果我嘗試使用（設置APP_ID自己）

remote_api_stub.ConfigureRemoteApi(app_id=myappid, path='/_ah/remote_api', 
            auth_func=lambda: ('myemail', 'mypass'), 
            servername='myappid.appspot.com') 

我得到同樣的HTTP錯誤404像以前一樣

As far作爲不使用OAuth時使用的電子郵件和密碼組合，我已經嘗試了對應用擁有所有權的用戶名/密碼，但似乎並不奏效。

爲了使命令行ConfigureRemoveApiForOAuth能夠正常工作，我必須使用密鑰設置一個服務帳戶。我想知道如何使用該電子郵件remote-api-service@myappid.iam.gserviceaccount.com，但我不確定密碼是什麼，所以我想這可能是不正確的。

我也試過在appengine_config.py裏面設置remote_api_stub而不是在個別的處理程序中，所有的問題都是一樣的。

我也試過這兩個與vm：true和沒有在app.yaml，它似乎沒有區別。

總結一下： 是否可以使用remote_api_stub從谷歌應用程序本身的代碼連接到谷歌應用程序引擎數據存儲？我已經可以從應用程序的外部訪問數據存儲區了，但是裏面運行的任何代碼似乎都不起作用。

感謝

編輯：有問題的帳戶具有「允許安全性較低的應用程序登錄是在谷歌設置爲或任何設置ON」

我能夠通過使用gcloud庫來解決這個問題。
