在谷歌应用引擎中接收邮件

我正在阅读关于 Receiving Mail . 我按照说明更新了app.yaml文件:

application: hello-1-world
version: 1
runtime: python
api_version: 1

handlers:
- url: /favicon.ico
  static_files: static/images/favicon.ico
  upload: static/images/favicon.ico

- url: /_ah/mail/.+
  script: handle_incoming_email.py 
  login: admin

- url: /.*
  script: hw.py

inbound_services:
- mail

创造了一个 handle_incoming_email.py

import cgi
import os
import logging
from google.appengine.api import users
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
from google.appengine.ext import db
from google.appengine.api import mail
from google.appengine.ext.webapp.mail_handlers import InboundMailHandler

class ReceiveEmail(InboundMailHandler):
    def receive(self,message):
        logging.info("Received email from %s" % message.sender)
        plaintext = message.bodies(content_type='text/plain')
        for text in plaintext:
            txtmsg = ""
            txtmsg = text[1].decode()
            logging.info("Body is %s" % txtmsg)
            self.response.out.write(txtmsg)

application = webapp.WSGIApplication([
  ReceiveEmail.mapping()
], debug=True)

def main():
    run_wsgi_app(application)
if __name__ == "__main__":
    main()

我也有 hw.py 我以前练习发邮件。那是有用的。

现在我去 http://localhost:8081/_ah/admin/inboundmail 并发送电子邮件至 help@hello-1-world.appspotmail.com

有人能告诉我如何处理这封邮件吗?如何访问电子邮件的内容?我有密码

self.response.out.write(txtmsg)

在里面 处理接收的电子邮件.py 但这并不能印出任何东西。

如果有人能澄清接收电子邮件的工作原理,我将不胜感激。

例如, in this question

class MailHandler (InboundMailHandler):
  def receive(self, message):
    sender = message.sender
    user_account = db.GqlQuery("SELECT * FROM Task WHERE user = :1", sender).fetch(5)

据我所知 sender 是发件人的电子邮件。所以,在我的例子中,我如何访问发件人的电子邮件地址。

另外,为什么我需要一个单独的脚本来处理传入邮件?为什么我不能把 ReceiveEmail 我的处理器 H.Py 脚本?如果我这样做,我该把线放在哪里

application = webapp.WSGIApplication([
  ReceiveEmail.mapping()
], debug=True)

如果你能帮我解答这些问题,我将不胜感激。

( I asked the same question 但没有答案。)
