如何在Django中返回401 Unauthorized？

from django.http import HttpResponse

def my_view(request):
    response = HttpResponse("Unauthorized", status=401)
    response['WWW-Authenticate'] = 'Basic realm="API"'  # 可选：添加认证头
    return response

from django.http import JsonResponse

def api_view(request):
    return JsonResponse(
        {"error": "Authentication required"},
        status=401,
        headers={'WWW-Authenticate': 'Bearer'}
    )

from functools import wraps
from django.http import JsonResponse

def require_auth(view_func):
    @wraps(view_func)
    def wrapper(request, *args, **kwargs):
        if not request.user.is_authenticated:
            return JsonResponse({"error": "Unauthorized"}, status=401)
        return view_func(request, *args, **kwargs)
    return wrapper

@require_auth
def protected_view(request):
    return JsonResponse({"data": "敏感数据"})

from rest_framework.response import Response
from rest_framework.decorators import api_view, permission_classes
from rest_framework.permissions import IsAuthenticated

@api_view(['GET'])
@permission_classes([IsAuthenticated])
def drf_view(request):
    return Response({"data": "ok"})

# 未认证时会自动返回401
