"detail": "Authentication credentials were not provided." 一般观点
"detail": "Authentication credentials were not provided." for general views
我已经创建了自定义用户模型并应用了 Djoser 身份验证和 jwt。但是在此之后，当我尝试获取产品视图请求时，出现此错误：

我已经搜索过，但他们说要更改 REST_FRAMEWORK 的身份验证权限，如您所见，我已经完成了，但无济于事。
您是否在 headers 中添加了令牌？。如果您已添加，则访问令牌必须已过期，以便您可以从刷新令牌中获取新的访问令牌
在 headers 中添加令牌，如不记名令牌。
要在非认证用户上打开 API，您需要在 authentication_classes 上给它一个空列表：
from rest_framework.decorators import api_view, authentication_classes, permission_classes
@api_view(['GET'])
@authentication_classes([]) # Add this
