Facebook OAuth 2 Tutorial
=========================
Setup a new web application client in the `Facebook APP console`_
When you have obtained a ``client_id``, ``client_secret`` and registered
a callback URL then you can try out the command line interactive example below.
.. _`Facebook APP console`: https://developers.facebook.com/apps
.. code-block:: pycon
>>> # Credentials you get from registering a new application
>>> client_id = '<the id you get from facebook>'
>>> client_secret = '<the secret you get from facebook>'
>>> # OAuth endpoints given in the Facebook API documentation
>>> authorization_base_url = 'https://www.facebook.com/dialog/oauth'
>>> token_url = 'https://graph.facebook.com/oauth/access_token'
>>> redirect_uri = 'https://localhost/' # Should match Site URL
>>> from requests_oauthlib import OAuth2Session
>>> from requests_oauthlib.compliance_fixes import facebook_compliance_fix
>>> facebook = OAuth2Session(client_id, redirect_uri=redirect_uri)
>>> facebook = facebook_compliance_fix(facebook)
>>> # Redirect user to Facebook for authorization
>>> authorization_url, state = facebook.authorization_url(authorization_base_url)
>>> print 'Please go here and authorize,', authorization_url
>>> # Get the authorization verifier code from the callback url
>>> redirect_response = raw_input('Paste the full redirect URL here:')
>>> # Fetch the access token
>>> facebook.fetch_token(token_url, client_secret=client_secret,
..> authorization_response=redirect_response)
>>> # Fetch a protected resource, i.e. user profile
>>> r = facebook.get('https://graph.facebook.com/me?')
>>> print r.content
