Python发送邮件功能示例【使用QQ邮箱】
(编辑：jimmy 日期: 2025/9/23 浏览：2)
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)
