Web Scraping Dynamic Facebook Content : Python

I want to scrape my own current online buddy chat list from my facebook account. I want to use python script and what I've learned so far is to inspect GET requests but I really dont see how to implement those into some simple script. If someone could help please.

the request if I'm not mistaken looks something like this http://ift.tt/1AtAO7R****myID****&__a=1&__dyn=7..some letters and..&__req=1r&__rev=**somenumbers****&ids[0]=***chatbuddyID****&so on....

import urllib
import re
import json

req = urllib.urlopen("code presented previousely").read()
print req
