我的 django 项目中有自定义管道。正在关注this example我正在尝试获取访问 token (以从 google plus 获取数据)，但它返回给我 TypeError: stringindexs Must be integers。
自定义管道:
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
最佳答案
解决方案很简单:
auth_token = json.loads(social.extra_data)['access_token']
关于当我尝试获取 access_token 时，Python-social-auth 管道返回 TypeError，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36751079/
