前言
因为有一些网站需要每日检查是否有问题,所以需要一个报警监控的机制,这个需要你指定你发送的邮箱和你接收的邮箱,就可以做到对网站自动监控了。
这里用的是python3.5
需要安装的插件:
1、smtplib:发邮件需要用到
2、pycurl:访问网站时会需要用到
3、linecache:在读取txt网站清单时需要用到
具体思路:
python程序从txt里面批量读取到网站的信息,通过Curl.py模拟浏览器去访问网站,并且把访问的结果写入到以自己的网站名称-日期.txt格式的文件中记录;有几种情况:
1、如果发现打不开了,直接发邮件提示网站已经打不开
2、发现可以打开,读取文件中上一次访问的情况(读取txt文件最后一行),
1)如果发现上一次是打不开的,发邮件提醒网站已经恢复了
2)如果发现上一次是打得开的(200的返回码),只是记录网站访问的日志就可以了
总共4个文件
Email.py是邮件类,主要用来发邮件的时候调用,这里需要按照你的情况改成你的邮箱(msg['From']),邮箱服务器地址(SMTP地址),和你的邮箱密码(SMTP.login)

site_moniter.py 这个文件为主程序,主要执行调用上面的函数,读取txt文件中的网站清单,如果网站打不开就发邮件出来告警
需要注意:
1、把xxxx@xxxx.com改成你自己的邮箱,
2、把文件路径改成自己的真实路径
