使用SimpleJWT登录时为AnonymousUser

问题描述 投票：0回答：1

我知道这不是第一个问题，但是其他主题对我没有帮助。我想使用djangorestframework-simplejwt来验证用户身份，一切都很好，因为涉及到获取用户。我总是得到AnonymousUser。

我通过访问api /令牌并传递凭据来获得令牌。令牌创建正确，其中包含正确的用户ID。当我尝试访问受保护的视图时，它允许我访问，但Django无法识别用户。

我相信这很明显，是因为几天前我开始学习drf，但是数小时的Google搜索没有帮助。

您使用的是JWTTokenUserAuthentication，而不是JWTAuthentication。后者会在您的请求中返回User对象，而前者会在请求中返回TokenUser。

请参见this explanation。
