Rewrite this property method If there are more arguments
        need  attach to the url. Like bellow:

            class NewSubClass(OAuth2):
                @property
                def authorize_url(self):
                    url = super(NewSubClass, self).authorize_url
                    url += '&blabla'
                    return url
