Hi, Arun
I also making an OAuth consumer with Google App Engine for Python.
The consumer uses simplegeo oauth2 library.
Here is my code snippet to get access token
when called back just after authorization.
....
user_info.authorized_request_token =
self.request.get("oauth_token")
user_info.verifier = self.request.get("oauth_verifier")
assert(user_info.request_token ==
user_info.authorized_request_token)
request_token =
oauth2.Token(user_info.request_token.__str__(),
user_info.request_token_secret.__str__())
request_token.set_verifier(user_info.verifier.__str__()) #
may not needed
request = oauth2.Request.from_consumer_and_token(consumer,
token=request_token, http_url = SP_ACCESS_TOKEN_URL)
signature_method = oauth2.SignatureMethod_HMAC_SHA1()
request.sign_request(signature_method, consumer,
request_token)
#self.response.out.write(request.to_header())
connection.request(request.method, SP_ACCESS_TOKEN_URL,
headers=request.to_header())
response = connection.getresponse()
response_read = response.read()
access_token = oauth2.Token.from_string(response_read)
user_info.access_token = access_token.key
user_info.access_token_secret = access_token.secret
user_info.put()
....
I hope it helps you somewhat.
