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)
email.py
#!/usr/bin/python
#-*- coding:utf-8 -*-
import sys
import smtplib
from email.mime.text import mimetext
from email.mime.multipart import mimemultipart
class email_send(object):
def __init__(self,msgto,data2,subject):
self.msgto=msgto
self.data2=data2
self.subject=subject
def sendemail(self):
# (attachment,html) = content
msg = mimemultipart()
msg[‘subject’] = self.subject
msg[‘from’] = ‘xxxx@xxxx.com.cn’
msg[‘to’] = self.msgto
html_att = mimetext(self.data2, ‘html’, ‘utf-8’)
#att = mimetext(attachment, ‘plain’, ‘utf-8’)
msg.attach(html_att)
#msg.attach(att)
try:
smtp = smtplib.smtp()
smtp.connect(‘smtp.xxxx.com’, 25)
smtp.login(msg[‘from’], ‘xxxx’) #改成自己的邮箱密码
smtp.sendmail(msg[‘from’], msg[‘to’].split(‘,’), msg.as_string())
return(‘邮件发送成功’)
except exception as e:
print(‘————–sss——‘,e)
def curl(self):
import pycurl
c=pycurl.curl()
#url=”www.luoan.com.cn”
#indexfile=open(os.path.dirname(os.path.realpath(__file__))+”/content.txt”,”wb”)
c.setopt(c.url,url)
c.setopt(c.verbose,1)
c.setopt(c.encoding,”gzip”)
#模拟火狐浏览器
c.setopt(c.useragent,”mozilla/5.0 (windows nt 6.1; rv:35.0) gecko/20100101 firefox/35.0″)
return c
curl.py 主要用来执行模拟浏览器访问网站并返回结果的文件
#!/usr/bin/python
#-*- coding:utf-8 -*-
import sys
import pycurl
class curl(object):
def __init__(self,url):
self.url=url
def curl_site(self):
c=pycurl.curl()
#url=”www.luoan.com.cn”
#indexfile=open(os.path.dirname(os.path.realpath(__file__))+”/content.txt”,”wb”)
c.setopt(c.url,self.url)
c.setopt(c.verbose,1)
c.setopt(c.encoding,”gzip”)
#模拟火狐浏览器
c.setopt(c.useragent,”mozilla/5.0 (windows nt 6.1; rv:35.0) gecko/20100101 firefox/35.0″)
return c
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
