在Django中对于基于函数的视图我们可以 @csrf_exempt 注解来标识一个视图可以被跨域访问。那么对于基于类的视图，我们应该怎么办呢？

简单来说可以有两种访问来解决

方法一：在类的 dispatch 方法上使用 @csrf_exempt

class InsertMyFavView(LoginRequiredMixin, View):    """    加入收藏    """    login_url = '/login/'    redirect_field_name = 'next'    def post(self, request):        user = request.user        data = json.loads(request.body.decode())        fav_id = data["fav_id"]        fav_type = data["fav_type"]        try:            user_fav = UserFavorite.objects.get(user=user, fav_id=fav_id, fav_type=fav_type)            if user_fav:                return JsonResponse({"status": "success", "msg": "已收藏!"})        except UserFavorite.DoesNotExist:            UserFavorite(user=user, fav_id=fav_id, fav_type=fav_type,add_time=datetime.now()).save()            return JsonResponse({"status": "success", "msg": "添加收藏成功!"})

方法二：在 urls.py 中配置

from django.conf.urls import urlfrom django.views.decorators.csrf import csrf_exemptimport AddMyFavViewurlpatterns = [    # 加入收藏    path('myfav/add/', csrf_exempt(AddMyFavView.as_view()), name="add_fav"),]
