Question

我的django项目中有自定义管道。在this example之后，我尝试获取访问令牌（从google plus获取数据），但它返回TypeError: string indices must be integers。

自定义渠道：

def user_details(strategy, details, response, user=None, *args, **kwargs):
    ....

    if user:
        if kwargs['is_new']:
            if "google" in kwargs['backend'].redirect_uri:
                ...
                try:
                    social = user.social_auth.get(provider='google-plus')
                    access_token = logger.warning(social.extra_data['access_token'])
                    ....

                except HTTPError:
                    pass
                .....

TypeError: string indices must be integers

Answer 1

解决方案很简单：

auth_token = json.loads(social.extra_data)['access_token']

当我尝试获取access_token时，Python-social-auth管道返回TypeError
