Failed to authorize tokeninfo oauth2 request using

Question

To access TokenInfo I use the Google APIs Client Library for Python (oauth2client app engine). I have received an oauth2 access token and this code works fine:

@decorator.oauth_aware        
def get(self):

    ....
    ....
    if decorator.has_credentials() :
        body = urllib.urlencode({'access_token': decorator.credentials.access_token})
        http = httplib2.Http()
        resp, content = http.request("https://www.googleapis.com/oauth2/v1/tokeninfo",method="POST", body=body)    

But when I use the decorator to create an authorized http instance:

@decorator.oauth_aware        
def get(self):

    ....
    ....
    if decorator.has_credentials() :
        http = decorator.http()                              
        resp, content = http.request("https://www.googleapis.com/oauth2/v1/tokeninfo",method="POST") 

I receive:

'status' : '400'
{
 "error": "invalid_token",
 "error_description": "either access_token or id_token required"
}

UPDATE-1

I studied oauth2client\client.py : decorator.http() not only authorizes the request, but also refreshes the access_token if it has been expired.

I very welcome ideas on how to solve this? Thanks for your help.

UPDATE-2 AND SOLVED

The TokeInfo API does not need any Authorization. The request itself has to contain the access_token. The Authorization header is ignored.
