Python automatically monitors websites and sends email alerts

This article describes how to regularly execute python scripts to access websites in batches. if you find that the website cannot be opened, you can send an email to the administrator's mailbox for warning immediately. For more information, see. Preface

Because some websites need to check whether there is a problem on a daily basis, an alarm monitoring mechanism is required. you need to specify the email address you sent and the email address you received, you can automatically monitor your website.

Here, python3.5 is used.

Plug-ins to be installed:

1,Smtplib: Used for sending emails

2,Pycurl: Used to access a website

3,Linecache: Used to read the txt website list

Specific ideas:

Records are recorded in the prepare format. There are several situations:

1. if you find that the website cannot be opened, send an email directly prompting you that the website cannot be opened.

2. you can open the file and read the last access to the file (read the last row of the txt file ),

1) If you find that the last attempt was rejected, send an email to remind you that the website has recovered.

2) If you find that the last attack was opened (200 return code), you only need to record the website access logs.

Email. py is an email class, mainly used for calling when sending an email. here, you need to change it to your mailbox (msg ['from']), email server address (SMTP address ), and your mailbox password (SMTP. login)

Email. py

Curl. py is a file used to simulate a browser to access a website and return 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") # simulate Firefox browser c. setopt (c. USERAGENT, "Mozilla/5.0 (Windows NT 6.1; rv: 35.0) Gecko/20100101 Firefox/35.0") return c

The site_moniter.py file is the main program. it mainly calls the above function to read the list of websites in the txt file. if the website cannot be opened, an alarm is sent.

Note:

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

2. change the file path to your own real path.

Summary

The method of using Python to automatically monitor the website and send email alerts has basically ended. I hope this will be helpful for everyone's learning work.
