Facebook signed_request POST parameter seems to get pre-processed by Django - http://developers.facebook.com/docs/authentication/signed_request/
Here is what I'm getting back in my view instead: <WSGIRequest GET:<QueryDict: {}>, POST:<QueryDict: {u'fb_sig_uninstall': [u'1'], u'fb_sig_added': [u'0'], u'fb_sig_locale': [u'en_US'], u'fb_sig_time': [u'1303506130.0511'], u'fb_sig_in_new_facebook': [u'1'], u'fb_sig_country': [u'us'], u'fb_sig_user': [u'1000016388xxxx'], u'fb_sig': [u'783xxxxxxxxxxxx], u'fb_sig_api_key': [u'a8f3xxxxxxxxxxxxxxxxxxxx'], u'fb_sig_app_id': [u'14xxxxxxxxxxx']}>, COOKIES:{}, -- You received this message because you are subscribed to the Google Groups "Django users" group.
