Python Requests and persistent sessions

Question

I am using the requests module (version 0.10.0 with Python 2.5). I have figured out how to submit data to a login form on a website and retrieve the session key, but I can't see an obvious way to use this session key in subsequent requests. Can someone fill in the ellipsis in the code below or suggest another approach?

>>> import requests >>> login_data =  {'formPosted':'1', 'login_email':'[email protected]', 'password':'pw'} >>> r = requests.post('https://localhost/login.py', login_data) >>>  >>> r.text u'You are being redirected <a href="profilePage?_ck=1349394964">here</a>' >>> r.cookies {'session_id_myapp': '127-0-0-1-825ff22a-6ed1-453b-aebc-5d3cf2987065'} >>>  >>> r2 = requests.get('https://localhost/profile_data.json', ...) 

Answer 1

You can easily create a persistent session using:

s = requests.Session() 

After that, continue with your requests as you would:

s.post('https://localhost/login.py', login_data) #logged in! cookies saved for future requests. r2 = s.get('https://localhost/profile_data.json', ...) #cookies sent automatically! #do whatever, s will keep your cookies intact :)
