用Python发邮件，QQ邮件，解决（Error: A secure connection is requiered(such as ssl)）

用Python发邮件，QQ邮件

之前查的网上的代码 都有

503 ‘Error: A secure connection is requiered(such as ssl)’之类的Bug.

QQ邮箱要求ssl，smtp.qq.com 端口号465.

因此我们把smtplib.SMTP()改成smtplib.SMTP_SSL()

#-*-coding:utf-8-*-
#==========================================
# 导入smtplib和MIMEText
#==========================================
from email.mime.text import MIMEText
import smtplib
#==========================================
# 要发给谁，这里发给3个人
#==========================================
mailto_list=["xxxx@qq.com","zhoul14@mails.tsinghua.edu.cn"]
#==========================================
# 设置服务器，用户名、口令以及邮箱的后缀
#==========================================
mail_host="smtp.qq.com"
mail_user="你的用户名"
mail_pass="你的授权码"#qq要求授权码，密码不行，你要在手机发短信具体的上qq邮箱网站上看
mail_postfix="qq.com"
#==========================================
# 发送邮件
#==========================================
