django社交认证从Google oauth2获得错误的access_token

Question

I am integrating google oauth2 to my website using django social auth. The problem is that with django social auth , I get an access_token like

ya29.2QCqpS-uKGXMNOP8yZnN6Z-F5LfVnyd7jwa8TaLP43nTEp2NUPB_p7Hi

While with the code sample from google code the access token is like :

ya29.2QCVXKc7XSNR3QxqRVAi0Z8Uz6mvolDGpezbZ9_r_oq7CXt01WvE9oUb90HXaynOLE4J8PjA5pzYDB

The first one does not work while the second one works fine

does anyone have any idea on this ?

Answer 1

all right. it turns out to be a problem of scope . the sample code set a default scope to mail.google.com while social-auth only have a default scope to read user information.

the difference in length of token must be related to the scope
