Python发送邮件功能示例【使用QQ邮箱】

本文实例讲述了Python发送邮件功能。分享给大家供大家参考，具体如下：

这里以QQ邮箱为例说明

登录邮箱点账号

开启smtp

开启时会要求你发送一条短信，发送完成后点已发送。

就有授权码了

代码如下，只需更改发件人、收件人等信息即可

# encoding: utf-8
import logging
import smtplib
from email.mime.text import MIMEText
import email.utils
from datetime import datetime
_logger = logging.getLogger('utils.mailclient')
class MailClient(object):
 def __init__(self, host, port, user, pwd=''):
   self._host = host
   self._port = port
   self._user = user
   self._pwd = pwd
   self._smtp_server = None
   self._debug = False
   self._keepalive = True
 def set_keepalive(self, keepalive):
   self._keepalive = keepalive
 def set_debug(self, debug):
   self._debug = debug
   if self._smtp_server is not None:
     self._smtp_server.set_debuglevel(self._debug)
 def _connect(self):
   if self._smtp_server is None:
     _smtp_server = smtplib.SMTP(self._host, self._port)
     _smtp_server.ehlo()
     _smtp_server.starttls()
     _smtp_server.set_debuglevel(self._debug)
     if self._pwd:
       _smtp_server.login(self._user, self._pwd)
     self._smtp_server = _smtp_server
   return self._smtp_server
 def _dispose(self):
   if self._smtp_server is not None:
     self._smtp_server.quit()
     self._smtp_server = None
 def send(self, to_addrs, subject, content, isdispose=True):
   _smtp_server = self._connect()
   if not isinstance(to_addrs, list):
     to_addrs = [to_addrs]
   _msg = MIMEText(content, 'html', 'utf-8')
   _msg['Subject'] = subject
   _msg['From'] = self._user
   _msg['To'] = '; '.join(to_addrs)
   _msg['Date'] = datetime.now().strftime('％Y-％d-％m ％H:％M:％S')
   _smtp_server.sendmail(self._user, to_addrs, _msg.as_string())
   isdispose and (not self._keepalive) and self._dispose()
 def send_mails(self, mails):
   _smtp_server = self._connect()
   for mail in mails:
     self._send_mail(mail.get('to'), mail.get('subject'), mail.get('content'), False)
   (not self._keepalive) and self._dispose()
 def close(self):
   self._dispose()
if __name__ == '__main__':
 logging.basicConfig(level=logging.DEBUG,
           format='％(asctime)s ％(name)s ％(levelname)s:％(message)s',
           datefmt='％Y-％m-％d ％H:％M:％S')
 import time
 s = MailClient('smtp.qq.com', 587, '10010@qq.com', '授权码') #  注意，此处端口要用587,465端口是ssl使用的。
 s.set_keepalive(False)
 s.set_debug(True)
 st = time.time()
 s.send('收信人邮箱地址', '测试', '测试邮件 From QQ') #要发送的账号、标题、内容
 print(time.time() - st)

希望本文所述对大家Python程序设计有所帮助。
