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 cCurl.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 csite_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
