我正在使用DjangoREST框架，并按照本教程在管理员用户通过身份验证时检索所有用户。
Class-based APIView of Django REST Framework
我正在使用Postman进行测试，并尝试检索系统中注册的所有用户的列表。
首先，我尝试使用Postman中的"User Login with Token" API创建必要的令牌，如下所示：

我复制了"token"键的值，并将其粘贴为Postman中"Get All Users" API的"Headers"部分中"Authorization"键的值，如下所示。这是一个GET请求，我得到的响应是错误"detail": "Authentication credentials were not provided."。

必要的代码片段如下所示：

• • 查看次数. py**

class UserAccountListView(APIView):
"""
    List of All Users in the System / Application
    * Requires Token Authentication.
    * Only Admin Users are able to access this view.
"""
authentication_classes = (TokenAuthentication, )
permission_classes = (IsAdminUser, )

def get(self, request, format=None):
    """
        Returns a List of All Users
    """
    full_names = [user.full_name for user in UsersAccount.objects.all()]
    return Response(full_names)

• • 设置. py**

REST_FRAMEWORK = {
    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticated',
        'rest_framework.permissions.IsAdminUser',
    ],
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework_simplejwt.authentication.JWTAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    ],

    "SLIDING_TOKEN_LIFETIME": timedelta(minutes=5),
    "SLIDING_TOKEN_REFRESH_LIFETIME": timedelta(days=1),
}

• • 网址. py**

urlpatterns = [
    path('', UsersAccountAPIOverview.as_view()),
    path("all", UserAccountListView.as_view()),
    path("register", UsersAccountRegistrationView.as_view()),
    path("token", UserAccountTokenObtainPairView.as_view()),
    path("token/refresh", TokenRefreshView.as_view()),
    path("token/verify", TokenVerifyView.as_view()),
]
