Django에서 JSON 응답을 올바르게 구성하는 방법은 무엇입니까?

def validate_user(request):
    if request.method == 'POST':
        ...
        array_to_js = [vld_id, vld_error, False]

        if vld_value == "TestUser":
            array_to_js[2] = True
            x = simplejson.dumps(array_to_js)
            return HttpResponse(x)
        else:
            ...
            return render_to_response('index.html', ...)

response_data = {}
response_data['vld_id'] = vld_id
response_data['vld_error'] = vld_error
response_data['valid'] = False

if vld_value == "TestUser":
    response_data['valid'] = True

json_response = json.dumps(response_data)
return HttpResponse(json_response, content_type="application/json")

from django.http import JsonResponse

return JsonResponse({
    'vld_id': vld_id,
    'vld_error': vld_error,
    'valid': False
})
