Python学习笔记——发邮件

参考：Python3实现163邮箱SMTP发送邮件

1.首先需要注册一个网易的邮箱，开启smtp服务，并使用其授权码

2.发送邮件的Python脚本

#!/usr/bin/python
# -*- coding: UTF-8 -*-

import smtplib
from email.header import Header
from email.mime.text import MIMEText

# 第三方 SMTP 服务
mail_host = "smtp.163.com"  # SMTP服务器
mail_user = "XXX"  # 用户名
mail_pass = "XXX"  # 授权密码，非登录密码

sender = "XXX@163.com"  # 发件人邮箱(最好写全, 不然会失败)
receivers = ["XXX@126.com"]  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱

content = '我用Python'
title = '人生苦短'  # 邮件主题  

def sendEmail():
    message = MIMEText(content, 'plain', 'utf-8')  # 内容, 格式, 编码
    message['From'] = "{}".format(sender)
    message['To'] = ",".join(receivers)
    message['Subject'] = title

    try:
        smtpObj = smtplib.SMTP_SSL(mail_host, 465)  # 启用SSL发信, 端口一般是465
        smtpObj.login(mail_user, mail_pass)  # 登录验证
        smtpObj.sendmail(sender, receivers, message.as_string())  # 发送
        print("mail has been send successfully.")
    except smtplib.SMTPException as e:
        print(e)

def send_email2(SMTP_host, from_account, from_passwd, to_account, subject, content):
    email_client = smtplib.SMTP(SMTP_host)
    email_client.login(from_account, from_passwd)
    # create msg
    msg = MIMEText(content, 'plain', 'utf-8')
    msg['Subject'] = Header(subject, 'utf-8')  # subject
    msg['From'] = from_account
    msg['To'] = to_account
    email_client.sendmail(from_account, to_account, msg.as_string())

    email_client.quit()

if __name__ == '__main__':
    sendEmail()
    # receiver = '***'
    # send_email2(mail_host, mail_user, mail_pass, receiver, title, content)
