3.CBV视图之csrf补充

CBV使用csrf装饰器关闭/开启 csrf验证，直接在函数上加装饰器无效的

#方法1
from django.views import View
from django.views.decorators.csrf import csrf_exempt, csrf_protect
from django.utils.decorators import method_decorator

class Login(View):
   #在视图类中函数上加装饰器是无效的，必须放在dispatch中【源码中反射处理的函数】
   @method_decorator(csrf_exempt)
   def dispatch(self, request, *args, **kwargs):
       return super(StudentsView,self).dispatch(request, *args, **kwargs)

    def users(self):
        pass

    def inofs(self):
        pass

#方法2 推荐
from django.views import View
from django.views.decorators.csrf import csrf_exempt, csrf_protect
from django.utils.decorators import method_decorator

#csrf处理方式，指向源码中的dispatch
@method_decorator(csrf_protect,name='dispatch')
class Login(View):
    def users(self):
        pass

    def inofs(self):
        pass
