是否有可能接收谷歌应用引擎的电子邮件退回通知 - python

Question

我有一个使用纯python的谷歌端点项目，我使用内置邮件发送电子邮件。但由于某些原因，电子邮件无法到达收件人（配额未用尽）。所以我想创建一个反弹通知器。到目前为止，我已经这样做了。

app.yaml

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

applications.py

from app.api.bounce.api import Bounce
APPLICATION = endpoints.api_server([Bounce])

bounce.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 [e-mail] 发送电子邮件时，此 API 未命中。任何帮助真的非常感谢。

回答我自己的问题

您无法使用 Google 应用引擎端点进行此设置。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='[e-mail]', sender='[e-mail]', 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仅允许管理员用户使用此 URL
