Google App Engine：接收電子郵件然後轉發它？

我有一個應用程序引擎應用程序，它接收電子郵件並將其元數據發送到腳本進行處理。它運作良好。代碼如下，並通過Github示例從Google提供。Google App Engine：接收電子郵件然後轉發它？

但問題是，如何將此腳本（或一般的App Engine）收到的電子郵件轉發到另一個電子郵件地址？

特別是，我的客戶在使用Gmail將我的電子郵件轉發給我時，我想接收他們的轉發請求，以便我作爲人員管理員可以批准他們。

您是否正在尋找？ https://cloud.google.com/appengine/docs/standard/python/mail/sending-mail-with-mail-api –

是我嗎？我想我是。「轉發」是最終用戶在as處引用的內容。但我想後端正在接收消息，然後發送它。我對電子郵件瞭解不多，所以如果在協議層面沒有「轉發」這樣的事情，那麼就是這樣。 – Warren

我相信你已經回答了你自己的問題然後：）導致只有你可以根據你的命令「轉發/發送」電子郵件 –

如上所述，您可以使用mail.send_mail（）函數在您當前的類中實現此目的。

from google.appengine.api import app_identity #[ If you want current user as the sender ] 
from google.appengine.api import mail 

def forward_mail(sender_address,forward_address,original_message,html_body,original_attachments): 
    # [START forward_mail] 
    message = mail.EmailMessage(
     sender= sender_address, 
     subject= original_message.subject, 
     to = forward_address, 
     sender = original_message.sender, 
     body = html_body, 
     attachments = original_attachments 
    ) 

    message.send() 
    # [END forward_mail]

然後在你的HandleEmail類中調用這個函數。

希望它有幫助
