Authentication problem with Weibo backend when integrate with Django application

[josseph]

Hi, I am trying to integrate python-social-auth into my application. I meet some problems when enable weibo backend.

The configurations like below.
1.

AUTHENTICATION_BACKENDS = (
    'social.backends.weibo.WeiboOAuth2',
    'django.contrib.auth.backends.ModelBackend',
) 

SOCIAL_AUTH_WEIBO_KEY = '*****'  // repalce the confidential key with star 
SOCIAL_AUTH_WEIBO_SECRET = '***' // remove the confidential secret with star

1. use the Django example to run the social authentication.

After I enter my weibo account and click on login, the authentication failed at the step of http://test.com/complete/weibo/?state=A5aliysJJjDpLyPLdxjVZQirhPaPkAHs&code=9ea8dc11dba1b494415ad82d2b48e804

Some exceptions thrown:

HTTPError at /complete/weibo/
405 Client Error: Method Not Allowed

Proposed one solution to fix this issue. #100
If the fix has potential regression issue, just ignore it.
