是否可以接收 Google 应用引擎 - python 的电子邮件退回通知？

Question

我有一个使用纯Python的谷歌端点项目，我使用内置的mail发送电子邮件。但由于某些原因，电子邮件无法到达收件人（配额未用完）。所以我想创建一个弹跳通知程序。到目前为止我已经做到了。

app.yaml

inbound_services:
- mail_bounce
handlers:
- url: /_ah/bounce
  script: applications.APPLICATION
  login: admin

应用程序.py

from app.api.bounce.api import Bounce

APPLICATION = endpoints.api_server([Bounce])

反弹.py

import endpoints
import logging

from protorpc import remote, message_types

from google.appengine.ext.webapp.mail_handlers import BounceNotification
from google.appengine.ext.webapp.mail_handlers import BounceNotificationHandler
from google.appengine.ext.webapp.mail_handlers import InboundMailHandler
from app.messages.auth import OutputAdminUserMessage


@endpoints.api(name='bounce', version='v1')
class Bounce(remote.Service):
    @endpoints.method(message_types.VoidMessage, OutputAdminUserMessage,
                      path="bounce", http_method="POST",
                      name="bounce")
    def post(self, request):
        bounce = BounceNotification(request.POST)
        logging.info('Bounce original: %s', bounce.original)
        logging.info('Bounce notification: %s', bounce.notification)

这似乎不起作用，当我尝试向 [电子邮件受保护] 发送电子邮件时，该 API 没有被命中。非常感谢任何帮助。

回答我自己的问题

您无法使用 google appengine 端点进行设置。我使用 webapp2 来设置它。

handle_bounced_email.py

import logging
import webapp2
from google.appengine.api import mail
from google.appengine.ext.webapp.mail_handlers import BounceNotification
from google.appengine.ext.webapp.mail_handlers import BounceNotificationHandler

class LogBounceHandler(BounceNotificationHandler):
    def receive(self, bounce_message):
        mail.send_mail(to='[email protected]', sender='[email protected]', subject='Bounced email',
                       body=str(self.request))
        logging.info('Received bounce post ... [%s]', self.request)
        logging.info('Bounce original: %s', bounce_message.original)
        logging.info('Bounce notification: %s', bounce_message.notification)

class BounceHandler(webapp2.RequestHandler):
    def post(self):
        bounce = BounceNotification(self.request.POST)
        logging.info('Bounce original: %s', bounce.original)
        logging.info('Bounce notification: %s', bounce.notification)

app = webapp2.WSGIApplication([
    ('/_ah/bounce', LogBounceHandler),
], debug=True)

现在在 app.yaml 中添加这些

inbound_services:
- mail_bounce

- url: /_ah/bounce
  script: handle_bounced_email.app
  login: admin

login:admin
