将响应从json嵌套字典转换为python字典

Question

I've searched and tried. I'm getting response back to get my access token. Im trying to get the keys from the response but it's not working. Here's what I've tried:

r=requests.post(url, data=req_params) 
data=r.json()

data type = dict; data prints:

{u'access_token':lrga242jt204j, u'user':{u'username':u'someoneismad',u'bio':u'im mad'}}

When I access it: unicode has no attribute get

Things I've tried

ast.literal_eval(data) #error malformed string
ast.literal_eval(str(data)) #malformed string
json.loads(r) #expected string or buffer
json.loads(str(r)) #no json could be decoded

[[update]] accessing dict

data.get('access_token')
data['access_token']
data.get('access_token', {}).get('user_id')

Problem is that I run into unicode error as indicated above

Answer 1

Did you try:

r=requests.post(url, data=req_params) 
data=r.json()
access_token = data['access_token']
user_data = data['user']
username = user_data['username']
#or
username = data['user']['username']

It should print your access token.
