Python automatically monitors websites and sends alert messages

Preface

Because there are some sites need daily check whether there is a problem, so need an alarm monitoring mechanism, this requires you to specify the mailbox you send and the mailbox you receive, you can do to the site automatic monitoring.

python3.5 is used here.

Plugins that need to be installed:

1,smtplib: E-mail needs to use

2,Pycurl: Access to the site will need to use

3,Linecache: When reading the TXT website list need to use

Specific ideas:

The Python program reads the information from the TXT in bulk to the website, accesses the website through the curl.py simulation browser, and writes the results of the visit to a file in its own website name-date. txt format; there are several situations:

1, if found not open, direct e-mail prompted the site has not opened

2, the discovery can open, read the file in the last access situation (read the TXT file the final line),

1) If you find that the last time is not open, e-mail reminder site has been restored

2) If the last time is found to be open (200 of the return code), just record the site access to the log can be

A total of 4 files

email.py is the message class, mainly used to send the message when the call, here need to follow your case to change to your mailbox (msg[' from '), the Mailbox server address (SMTP address), and your mailbox password (smtp.login)

email.py

Curl.py is primarily used to perform a file that simulates a browser's access to a Web site and returns results

#!/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 this file as the main program, mainly execute call the above function, read the TXT file in the Web site list, if the website can not open to send an email alarm

Need to note:

1, change the xxxx@xxxx.com to your own mailbox,

2. Change the file path to your true path

Summarize

Using Python to automatically monitor the site and send email alerts to this is basically the end of the hope that everyone's study work can be helpful.
