在Google App Engine中接收邮件 [英] Receiving Mail in Google App Engine

问题描述

我正在阅读有关接收邮件的教程。我按照说明更新了app.yaml文件：

 应用程序：hello-1-world 
版本：1 
运行时：python 
 api_version：1 
 
处理程序：
  -  url：/favicon.ico 
 static_files：static / images / favicon.ico 
上传：static / images / favicon.ico 
 
  -  url：/_ah/mail/.+ 
脚本：handle_incoming_email.py 
登录：admin 
 
  -  url：/.* 
 script：hw.py 
 
 inbound_services：
  -  mail 
  

并创建了一个 handle_incoming_email.py

  import cgi 
 import os 
 import log 
 from google.appengine.api import users 
 from google.appengine.ext import webapp 
 from google.appengine .ext.webapp.util import_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接收（自我，消息）：
 logging.info（从％s收到的电子邮件％message.sender）
 plaintext = message.bodies（content_type ='text / plain'）
纯文本：
 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）
如果__name__ ==__main__：
 main（）
  

我也有用于练习发送电子邮件的 hw.py 。

现在我去 http：// localhost：8081 / _ah / admin / inboundmail 和发送电子邮件至 [e-mail]

任何人都可以向我解释我处理此电子邮件？如何访问电子邮件的内容？我有代码

  self.response.out.write（txtmsg）
  / pre> 
 
 
在 handle_incoming_email.py 中，但不打印任何内容。
 
 
 
如果有人澄清接收电子邮件的工作原理，我将非常感激。
 
 
 
例如，这个问题 
类MailHandler（InboundMailHandler）：
 def receive（self，message）：
 sender = message.sender 
 user_account = db.GqlQuery（SELECT * FROM Task WHERE user =：1，发件人）.fetch（5）
  
据我所知发件人是发件人的电子邮件。所以，在我的情况下，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收到的邮件？为什么我不能将 ReceiveEmail 处理程序放在我的 hw.py 
  application = webapp.WSGIApplication（[
 ReceiveEmail.mapping ）
]，debug = True）
  
如果可以帮助我，我将不胜感激这些问题。
 
 
 
（我在GAE组中问了同一个问题，但没有答案。）
解决方案
 p>是[e-mail]一个有效的谷歌用户？ GAE只能从您的应用程序的谷歌用户接收/发送邮件。 
您的代码似乎正确。
 
 
 
另外，为什么我需要一个单独的脚本来处理收到的邮件？为什么我不能把ReceiveEmail处理程序在我的hw.py - >主要脚本是处理url请求，我认为这样更清楚。
 
I am reading the tutorial about Receiving Mail. I updated the app.yaml file as instructed:
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
And created a 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()
I also have hw.py that I used to practice sending email. That one works.

Now I go to http://localhost:8081/_ah/admin/inboundmail and send an email to [e-mail]

Can anyone explain to me how I process this email? How do I access the content of the email? I have the code
self.response.out.write(txtmsg)
in handle_incoming_email.py but that does not print anything.

I would greatly appreciate if someone clarify how receiving email works.

For instance, 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)
as far as I understand sender is the email of the sender. So, in my case, how do I access the sender email address.

Also, why do I need to have a separate script to handle incoming mail? Why can't I put the  ReceiveEmail handler in my hw.py script? If I do that, where do I put the line 
application = webapp.WSGIApplication([
  ReceiveEmail.mapping()
], debug=True)
I would be grateful if you can help me with these questions.

(I asked the same question in GAE group but there were no answers.)
解决方案
Is [e-mail] a valid google user? GAE can receive/send mails only from the google user of your application.
Your code seems correct.

"Also, why do I need to have a separate script to handle incoming mail? Why can't I put the ReceiveEmail handler in my hw.py" -> the main script is to handle url request, I think is much clearer in this way.
