Python-cookie Bypass Verification Code Login

Objective

Some login interface will have verification code: SMS Verification Code, graphics verification Code, and so on, this kind of login verification code parameters can be obtained from the background (or check the database most directly).

It doesn't matter if you get it, you can bypass the captcha by adding a cookie.

First, catch the login cookie

1. Login will generate a logged in status of the cookie, then only need to add this value directly into the cookie.

2. You can log in manually once, and then crawl this cookie, you need to use the Grab Kit tool fiddler

3. First open the Blog Park login screen, manually enter the account and password (tick the next automatic login)

4. Open the Fiddler Capture tool, refresh the login home page, is the cookie before login

5. After the successful login, then look at the cookie changes, found that two sets of parameters, many of these two sets of parameters is what we want, copy out, one will be useful
