-view的封装过程有空可以看一下

-ViewSetMixin

	# 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

　　-使用:

	-urls.py中

		url(r'^publishs/', views.PublishView.as_view({'get': 'aaa','post':'ddd'})),

		url(r'^bbb/', views.PublishView.as_view({'get': 'bbb','post':'ccc'})),

	-视图类中:

		class PublishView(ViewSetMixin,APIView):   #注意这里类的顺序，ViewSetMixin写在前面

			def aaa(self,request):

				return Response({'status':100})

			def bbb(self,request):

				return Response({'bb': "bbb"})

url(r'^publish/$', views.PublishView.as_view()),

url(r'^publish/(?P<pk>\d+)/$', views.PublishDetailView.as_view()),
