Django -如何在身份验证期间返回JSON响应而不是HTML？

from django.contrib.auth.backends import ModelBackend
from django.contrib.auth import get_user_model
from django.http import JsonResponse

UserModel = get_user_model()

class JSONBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            user = UserModel.objects.get(username=username)
            if user.check_password(password):
                return user
        except UserModel.DoesNotExist:
            pass
        return None

    def get_user(self, user_id):
        try:
            return UserModel.objects.get(pk=user_id)
        except UserModel.DoesNotExist:
            return None

    def authentication_failed(self, request, message=None, **kwargs):
        return JsonResponse({'error': message}, status=401)

AUTHENTICATION_BACKENDS = [
    'myapp.backends.JSONBackend',
    'django.contrib.auth.backends.ModelBackend',
]

from django.contrib.auth.decorators import login_required
from django.http import JsonResponse

@login_required
def my_view(request):
    # 处理逻辑
    return JsonResponse({'message': 'Success'})
