python之在代理后面的 Django 中使用 send_mail 时出现错误_编程设计

我正尝试使用 gmail 从我的 Django 应用程序发送电子邮件。我将这些电子邮件设置添加到 settings.py

EMAIL_HOST = 'smtp.gmail.com' 
EMAIL_HOST_USER = 'myemail@gmail.com' 
EMAIL_HOST_PASSWORD = 'mypassword' 
EMAIL_PORT = 587 
EMAIL_USE_TLS = True

但它抛出这个名称解析错误:

Traceback (most recent call last): 
File "/usr/lib/python3.4/code.py", line 90, in runcode 
  exec(code, self.locals) 
File "<console>", line 1, in <module>

  self.sock = self._get_socket(host, port, self.timeout)

  for res in _socket.getaddrinfo(host, port, family, type, proto, flags): 
socket.gaierror: [Errno -2] Name or service not known

注意:我在代理后面工作。

此外，我尝试通过套接字连接到 google.com:

import socket 
socket.gethostbyname('www.google.com')

它抛出:

[Errno 11001] getaddrinfo failed

请您参考如下方法:

在 gmail.com 中启用 pop3
为django应用创建特定的密码 ( http://support.google.com/accounts/bin/answer.py?hl=en&answer=185833 )
