CBV添加装饰器

from django.utils.decorators import method_decorator

（1）添加在函数上

class CbvTest(View):
    @method_decorator(login_auth)
    def get(self):
        return HttpResponse('get请求')

    def post(self):
        return HttpResponse('post请求')

（2）添加在类上

@method_decorator(login_auth,name='get')
@method_decorator(login_auth,name='post')
class CbvTest(View):
    def get(self):
        return HttpResponse('get请求')

    def post(self):
        return HttpResponse('post请求')

（3）重写dispatch方法

• 作用于当前类里面的所有的方法

class CbvTest(View):
    @method_decorator(login_auth)
    def dispatch(self, request, *args, **kwargs):
        pass

    def get(self):
        return HttpResponse('get请求')

    def post(self):
        return HttpResponse('post请求')
