python - 在 python 中发送邮件时出错

Question

pwd = "mypassword"
import smtplib

server = smtplib.SMTP('smtp.gmail.com')
server.ehlo()
server.starttls()
server.login("gvpcse113@gmail.com",pwd)

msg = "YOUR MESSAGE!"
server.sendmail("gvpcse113@gmail.com", "sender@xyz.com", msg)
server.quit()

我试过通过 python 发送邮件...
错误:

Traceback (most recent call last):
  File "H:/my projects/PythonCourse/test_cont/mail_test4.py", line 4, in <module>
    server = smtplib.SMTP('smtp.gmail.com')
  File "C:\Python27\lib\smtplib.py", line 256, in __init__
    (code, msg) = self.connect(host, port)
  File "C:\Python27\lib\smtplib.py", line 316, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "C:\Python27\lib\smtplib.py", line 291, in _get_socket
    return socket.create_connection((host, port), timeout)
  File "C:\Python27\lib\socket.py", line 557, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
socket.gaierror: [Errno 11001] getaddrinfo failed

我正在通过代理连接
我在windows中通过cmd设置代理。请帮我解决这个问题。

更新:
我确定互联网连接:

import urllib2

def internet_on():
    try:
        response=urllib2.urlopen('https://www.google.co.in',timeout=1)
        return True
    except urllib2.URLError as err: pass
    return False

print internet_on()

输出为 True

你的代码对我来说工作正常，所以它可能是连接设置。

尝试将服务器更改为:

server = smtplib.SMTP('64.233.184.108')

(就是smtp.gmail.com的IP地址，用来绕过DNS解析)
