windows环境下IP监控脚本配置并在IP变动时向邮箱发送邮件

邮箱准备

1.注册126邮箱

2.邮箱设置POP3/SMTP服务

3.保存授权码

python脚本

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


def send_email(new_ip):
    # 创建 SMTP 对象
    smtp = smtplib.SMTP()
    # 连接（connect）指定服务器
    smtp.connect("smtp.126.com", port=25)
    # 登录，需要：登录邮箱和授权码
    smtp.login(user="monitor_lzh@126.com", password="*****保存的授权码*****")

    message = MIMEText('P330工作站 IP变更为' + new_ip, 'plain', 'utf-8')
    message['From'] = Header("P330 IP变更监控", 'utf-8')
    message['To'] = Header("Users", 'utf-8')
    message['Subject'] = Header('P330工作站IP变更 ' + new_ip, 'utf-8')

    smtp.sendmail(from_addr="monitor_lzh@126.com", to_addrs="指定收件邮箱", msg=message.as_string())

    if os.path.exists('./email.txt'):
        fr = open('./email.txt','r',encoding='utf-8')
        emails = fr.readline().strip('\n').split('\n')
        if emails:
            for email in emails:
                if email.strip() != '' and email.strip() != '\n' and '@' in email:
                    smtp.sendmail(from_addr="monitor_lzh@126.com", to_addrs=email, msg=message.as_string())

def main():
    log_path = './ip_log.log'
    fa = open(log_path, 'a', encoding='utf-8')
    cur_ip = socket.gethostbyname(socket.gethostname())
    if not os.path.isfile(log_path) and fa.read().strip() == '':
        fa.write(cur_ip + '##')
        send_email(cur_ip)
        fa.close()
        return 0

    with open(log_path, 'r', encoding='utf-8') as fr:
        old_ip = fr.read().strip('##').split('##')[-1]
        if old_ip != cur_ip or old_ip is None:
            # print('old:', old_ip)
            fa.write(cur_ip + '##')
            send_email(cur_ip)

    fa.close()


if __name__ == '__main__':
    main()
