12、Python 运行代码监控及邮件发送

问题描述：使用python进行运行程序监控，一旦程序出现问题，立即重新启动，并进行邮件发送提醒

 

import os
from email.mime.text import MIMEText
from email.header import Header
import smtplib
import time
os.system("nohup python3 generate_waiting.py  >> waiting.log 2>&1 &") # 前提 generate_waiting 存在
os.system("nohup python3 generate_running.py  >> running.log 2>&1 &") # 前提 generate_running 存在

def send_email(info):
    from_addr = '[email protected]' #发件邮箱
    password = 'jelpkwpaxxejbdfh' #邮箱授权密码
    to_addr = ['[email protected]','[email protected]'] #收件邮箱
    smtp_server = 'smtp.qq.com' #SMTP服务器

    message ='hello，world！'
    msg = MIMEText(message,'plain','utf-8')
    msg['Subject'] = Header("来自Python的邮件",'utf-8')
    msg['From'] = Header(from_addr)



    for email_id,email in enumerate(to_addr):
      msg['To'] = Header(email,'utf-8')
      try:
         server = smtplib.SMTP(smtp_server,25) #第二个参数为默认端口为25，有些邮件有特殊端口
         print('开始登录')

         print('登录成功')
         print("邮件开始发送")
         server.sendmail(from_addr,email,msg.as_string())  #将msg转化成string发出
         server.quit()
         print("邮件发送成功")

  time.sleep(15)
