Python enables automatic monitoring of websites and sending email alerts

By timed execution of Python script, you can implement regular batch access to the site, if you find that the site is not open, the first time to send mail to the administrator mailbox for early warning

python3.5 is used here.

Plugins that need to be installed:

Smtplib: E-mail needs to be used

Pycurl: When visiting the website, you will need to use

Linecache: When reading the TXT Web site list, you 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

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)

Note: 1, change [email protected] to your own mailbox,

2. Change the file path to your true path
