Error getting json using oauthlib python

Im trying to get a pretty json but always have the same error expected string or buffer my code is below

        import urllib2
        import json
        import logging
        from libs.requests_oauthlib import OAuth1Session
        import libs.requests2

        coke = OAuth1Session('user_key',
                             client_secret='user_secret',
                             resource_owner_key='key',
                             resource_owner_secret='key_secret')

        headers = {'content-type': 'application/json'}
        url = "http://test.hdp.pengostores.mx/api/rest/orders"


        response = coke.get(url,headers=headers)
        self.response.out.write(response.text)

In error message you use

json.loads( coke.get(...) )

but get() returns response object - you have to use get().text or get().content (instead of get()) to get text or bytes.

Or try 

 data = coke.get(...).json()

to get directly JSON converted to Python data.

EDIT: to pretty print Python data use pprint.pprint(data) or convert Python data to JSON string using json.dumps()

See example from doc: https://docs.python.org/2/library/json.html

Pretty printing:

>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True,
...                  indent=4, separators=(',', ': '))
{
    "4": 5,
    "6": 7
}
