How to login Facebook with Request module for further access?
-
Hi All, with the help of some nice guys here, I finished my first pythonista little project, a facebook video downloader: https://gist.github.com/henryaukc/6fd00b8baee4c069a2b44e574829469f
It works for downloading videos posted by the pages that open to public access. I would like to enhance it a bit so that it can download videos from my friends page. It requires to login the facebook with my credentials and save the cookies to further access the pages. I have searched the web for solutions but it seems all outdated and see if someone can give me some hints?
I will continue to investigate it and post my result here too. Thanks a lot.

Thanks @abcabc ! I have tried the script and it works fine after some small modification. I would try to update my script accordingly later.

Sorry, maybe I was not checking thoroughly or it is not working anymore, my script to login facebook fails now....
Can someone shed some light on it?
