[python] simply use selenium to write web page login and sign-in functions without interface Google browser

Use python to write a simple function of automatic login and sign-in on server-side web pages

Note: It is only used for testers to automate script testing, do not use it for other purposes

-------------------------------------------------------------------------------------

Preparation

1. selenium , a plug-in to control the browser

Install selenium using pip: pip install selenium

2. No interface browser, that is, a browser without interface started on the server side

Download Headless Google Chrome
