So I've spent way to much time on this, and it seems to me like it should be a simple fix. I'm trying to use Facebook's Authentication to register users on my site, and I'm trying to do it server side. I've gotten to the point where I get my access token, and when I go to:
I get the information I'm looking for as a string that's like this:
{"id":"123456789","name":"John Doe","first_name":"John","last_name":"Doe","link":"http:\/\/","gender":"male","email":"jdoe\u0040gmail.com","timezone":-7,"locale":"en_US","verified":true,"updated_time":"2011-01-12T02:43:35+0000"}
It seems like I should just be able to use dict(string) on this but I'm getting this error:
ValueError: dictionary update sequence element #0 has length 1; 2 is required
So I tried using Pickle, but got this error:
KeyError: '{'
I tried using django.serializers to de-serialize it but had similar results. Any thoughts? I feel like the answer has to be simple, and I'm just being stupid. Thanks for any help!

This data is JSON! You can deserialize it using the built-in json module if you're on Python 2.6+, otherwise you can use the excellent third-party simplejson module.
import json # or `import simplejson as json` if on Python < 2.6
json_string = u'{ "id":"123456789", ... }'
obj = json.loads(json_string) # obj now contains a dict of the data
Use ast.literal_eval to evaluate Python literals. However, what you have is JSON (note "true" for example), so use a JSON deserializer.
>>> import json
>>> s = """{"id":"123456789","name":"John Doe","first_name":"John","last_name":"Doe","link":"http:\/\/","gender":"male","email":"jdoe\u0040gmail.com","timezone":-7,"locale":"en_US","verified":true,"updated_time":"2011-01-12T02:43:35+0000"}"""
>>> json.loads(s)
{u'first_name': u'John', u'last_name': u'Doe', u'verified': True, u'name': u'John Doe', u'locale': u'en_US', u'gender': u'male', u'email': u'', u'link': u' u'timezone': -7, u'updated_time': u'2011-01-12T02:43:35+0000', u'id': u'123456789'}
In Python 3.x
import json
t_string = '{"Prajot" : 1, "Kuvalekar" : 3}'
res = json.loads(t_string)
print(res) # <dict> {"Prajot" : 1, "Kuvalekar" : 3}
