Python how to download protected files - Audio/video stream recording forums

I would like to download a "token" protected file and to use my cookie file in order to avoid multiple re-login. The way i proceed is as follow

First of all, import the cookie

Code:

import requests, cookielib



    cj = cookielib.MozillaCookieJar('cookies.txt')

    cj.load()

    r = requests.get(url, cookies=cj)

This is where i get a problem with, I must follow these steps in order to successfully download the desired file. (Everything in square brackets have to be replaced)

Code:

>> http://videoXXXXXXXX.fr/index.php?optio … &video_id=[VIDEO_ID]&load=1

Recover the cookie provided via "header set-cookie" 

>> http://videoXXXXXXXX.fr/index.php?optio … &video_id=[VIDEO_ID]

Recover the "order_id" in the sent back page [ORDER_ID]

>> http://videoXXXXXXXX.fr/index.php?optio … &order_id=[ORDER_ID]

Recover the response token: [Token]

>> http://videoXXXXXXXX.fr/index.php?optio … raw&token=[Token]&order_id=[ORDER_ID]

This step allow the activation of the cookie recovered in step 1 as well as to obtain the complete file

But the truth is, I would like some help in order to do all that in "Python"

Thank you in advance for your time, as well as your help.
