通过定时执行python脚本,可以实现定期批量访问网站,如果发现网站打不开,第一时间发邮件到管理员邮箱进行预警
这里用的是python3.5
需要安装的插件:
smtplib:发邮件需要用到
pycurl:访问网站时会需要用到
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 sysimport smtplibfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartclass 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 sysimport pycurlclass 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
