Question

我正在使用python-social-auth，当我尝试刷新Google Oauth2访问令牌时，我收到以下错误：

[2017-02-15 14:41:00,089: ERROR/MainProcess] Task tasks.tasks.test_login[169e5810-489d-4134-af8f-db3b80629fd2] raised unexpected: HTTPError(u'400 Client Error: Bad Request for url: https://accounts.google.com/o/oauth2/token',)

    raise HTTPError(http_error_msg, response=self)
HTTPError: 400 Client Error: Bad Request for url: https://accounts.google.com/o/oauth2/token

我使用以下代码刷新访问令牌：

from social.apps.django_app.utils import load_strategy

w_user = WUser.objects.get(auth_user=A('username','xxxx'))
social = UserSocialAuth.objects.get(user_id=w_user.auth_user.id)
strategy = load_strategy()
social.refresh_token(strategy)

我做错了吗？

Answer 1

致电social.get_access_token(load_strategy())时遇到相同的问题。如果您不想手动实施Google登录，则可以使用这种解决方法，它迫使用户重新进行身份验证以刷新其令牌。

try:
    strategy = load_strategy()
    access_token = social.get_access_token(ls)
except HTTPError as e:
    return HttpResponseRedirect(reverse('social:begin', kwargs={'backend': "google-oauth2"}))

Answer 2

正如上面的yilmazhuseyin所指出的，该问题与刷新令牌不存在有关。您需要在参数中传递access_type='offline'，以便Google返回刷新令牌。可以通过在settings.py中为django中的python-social-auth添加以下内容来实现：

SOCIAL_AUTH_GOOGLE_OAUTH2_AUTH_EXTRA_ARGUMENTS = {
    'access_type': 'offline',
}

更多详细信息可以在Google OAuth 2.0 documentation中找到。
