这是我目前的代码，我正在使用 Google Cloud SDK 和 Python 2.7：
import webapp2
import smtplib
import time
import imaplib
import email
class ReadMail(webapp2.RequestHandler):
def get(self):
mail = imaplib.IMAP4_SSL(imap.gmail.com)
mail.login('xxx@gmail.com','xxx')
mail.select('inbox')
type, data = mail.search(None, 'ALL')
mail_ids = data[0]
id_list = mail_ids.split()
first_email_id = int(id_list[0])
latest_email_id = int(id_list[-1])
for i in range(latest_email_id,first_email_id, -1):
typ, data = mail.fetch(i, '(RFC822)' )
for response_part in data:
if isinstance(response_part, tuple):
msg = email.message_from_string(response_part[1])
email_subject = msg['subject']
email_from = msg['from']
self.response.headers['Content-Type'] = 'text/plain'
self.response.write('Hello World?')
self.response.write('From :') + email_from + '\n'
self.response.write('Subject :') + email_subject + '\n'
app = webapp2.WSGIApplication([
('/', ReadMail),
], debug=True)
但是我收到此错误，并且网页未加载（HTML 500 错误）：
ERROR 2018-06-14 07:30:02,217 wsgi.py:279]
Traceback (most recent call last):

我看到问题在于调用模块，但由于我对 python 完全陌生，所以我很难理解它是如何工作的。任何帮助，将不胜感激！
编辑
如果我删除'Request.Handler'from class ReadMail(webapp2.RequestHandler)，我会收到此错误：
File "C:\Users\xxx\desktop\pythontest\demo\hello.py", line 8, in <module>
class ReadMail(webapp2):
TypeError: Error when calling the metaclass bases
