Learn to use Selenium library to simulate landing, and save the cookie as a local file, then for later use (requests module), with the selenium simulation Landing, More smoothly, did not encounter the need to verify code, the code is placed in a module named cookiesload.py :

Due to personal habits, a settings.py configuration module was used:

1 # User name 2 ' 173866016XX ' 3 4 # Password 5 ' XXX '

After execution, a folder named Cookies is generated in the current working directory and thecookies.txt file is in that folder. In the event that the cookie is not expired, you will be able to access it later without having to log in again and load the cookie file directly.

The Chrome browser used above has an interface mode, if you do not want the browser to run directly in the background, do not pop up the interface, you can:

1  from Import Options 2 3 options = options ()4 options.add_argument ('--headless' )5 brower = Chrome (options=options)
