python - 消息实例在 Google 应用引擎邮件接收中没有属性 'read'

Question

接收处理程序中的代码

class LogSenderHandler(InboundMailHandler):
   def receive(self, mail_message):
    logging.info("Received a message from: " + mail_message.sender)
    #logging.info("Received a message from: " + mail_message.attachments)
    logging.info("Received a message from: " + mail_message.date)
    logging.info("Received a message from: " + mail_message.subject)
    report = DocFile()
    report.doc_name = mail_message.subject
    if mail_message.attachments is not None:
        report.doc_file = mail_message.attachments
    else:
        report.doc_file = mail_message.bodies(content_type='text/plain')
    report.put()

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

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

url.py 中的代码

inbound_services:
- mail

handlers:
- url: /_ah/mail/.+ 
script: handle_incoming_email.py

当我尝试从 http://localhost:8080/_ah/admin/inboundmail 发送一封简单的电子邮件时出错

Message send failure

    Traceback (most recent call last):
  File "F:\Program Files\Google\google_appengine\google\appengine\ext\webapp\__init__.py", line 509, in __call__
    handler.post(*groups)

    mime_message = _parse_mime_message(mime_message)
  File "F:\Program Files\Google\google_appengine\google\appengine\api\mail.py", line 232, in _parse_mime_message
    return email.message_from_file(mime_message)

    return Parser(*args, **kws).parse(fp)
  File "F:\Python25\lib\email\parser.py", line 68, in parse
    data = fp.read(8192)
  AttributeError: Message instance has no attribute 'read'

编辑此错误仅出现在本地机器上，而不出现在应用引擎上

Answer 1

您有最新版本的 API 吗？收邮件功能需要1.2.6以上版本。

后来我在 google groups 看到我引用 Joshua Smith 的“解决方案”

"我发现你之前需要重启本地开发环境

进行任何入站邮件测试。否则，你会得到那个读取错误"

因此每次更改代码时，您必须重新启动服务器，即使只是添加空格(严重)
