Python automatically monitors websites and sends email alerts-Python Tutorial-php.cn

Preface

Because some websites need to check whether there are problems every day, an alarm monitoring mechanism is needed. This requires you to specify the email address you send and the email you receive. With your email address, you can automatically monitor the website.

The python3.5 used here

Plug-ins that need to be installed:

1. smtplib: Needed to send emails Go to

2. pycurl: You will need to use

when accessing the website 3. linecache: You will need to use it when reading the txt website list

Specific idea:

The python program reads website information in batches from txt, and uses Curl.py to simulate a browser to access the website , and write the results of the visit into a file in the format of your website name-date.txt; there are several situations:

1. If you find that it cannot be opened, send an email directly. Prompt that the website cannot be opened

2. It is found that it can be opened and the last accessed situation in the file is read (read the last line of the txt file),

1) If it is found that it cannot be opened last time, send an email to remind that the website has been restored

2) If it is found that it can be opened last time (200 return code), only the log of website access is recorded That’s it

A total of 4 files

Email.py is an email class, which is mainly used to call when sending emails. Here you need to follow In your case, change it to your email (msg['From']), email server address (SMTP address), and your email password (SMTP.login)

site_moniter.py This file is the main program, which mainly executes and calls the above functions, reads the website list in the txt file, and sends an email to alert if the website cannot be opened

2. Change the file path Become your own real path
