Django rest-framework framework - The routing component

路由：

    a. url(r'^(?P<version>[v1|v2]+)/v1/$',views.ViewView.as_view())
       url(r'^(?P<version>[v1|v2]+)/v1\.(?P<format>\w+)$',views.ViewView.as_view())

    b. url(r'^(?P<version>[v1|v2]+)/v1/(?P<pk>\d+)/$',views.ViewView.as_view({'get':'list',}))

    c. 自动生成路由
    	from rest_framework import routers

    	routers = routers.DefaultRouter()
    	routers.register(r'user'， views.UserInfoView)
    	routers.register(r'group'， views.GroupView)

    	urlpatterns = {
    		url(r'^(?P<version>[v1|v2]+)/', include(routers.urls)),
    	}
