ViewSetMixin 重写了as_view方法
from rest_framework.viewsets import ViewSetMixin
# ViewSetMixin 重写了as_view方法
# ViewSetMixin 写在前面,先找ViewSetMixin的as_view方法
# 用了ViewSetMixin ,视图类中,不需要再写get,post,delete....这些函数了,函数名可以自定义
# 而且这个视图类,可以响应多条路由
# class PublishView(ViewSetMixin,APIView):
# def aaa(self,request):
#
# return Response({'status':100})
# def bbb(self,request):
# return Response({'bb': "bbb"})

url(r'^publish/(?P<pk>\d+)', views.PublishView.as_view({'get': 'retrieve','put':'update','delete':'destroy'})),
