-url控制 　　-传统的url配置     url(r'^books/$', views.BookView.as_view()),     url(r'^books/(?P<pk>\d+)$', views.BookDetailView.as_view()), 　　-半自动     url(r'^publish/$', views.PublishView.as_view({'get':'list','post':'create'})),     url(r'^publish/(?P<pk>\d+)/$', views.PublishView.as_view({'get':'retrieve','put':'update','delete':'destroy'})), 　　-全自动(了解)     -能自动生成多条路由

自定义路由（原始方式）#

from django.conf.urls import url
from app01 import views
urlpatterns = [
    url(r'^books/$', views.BookView.as_view()),
    url(r'^books/(?P<pk>\d+)$', views.BookDetailView.as_view()),
]

class BookView(APIView):       def get(self, request):         book_list = models.Book.objects.all()         bs = BookSerializers(book_list, many=True)         return Response(bs.data)       def post(self, request):         # 添加一条数据         print(request.data)           bs=BookSerializers(data=request.data)         if bs.is_valid():             bs.save()  # 生成记录             return Response(bs.data)         else:               return Response(bs.errors)   class BookDetailView(APIView):     def get(self,request,pk):         book_obj=models.Book.objects.filter(pk=pk).first()         bs=BookSerializers(book_obj,many=False)         return Response(bs.data)     def put(self,request,pk):         book_obj = models.Book.objects.filter(pk=pk).first()           bs=BookSerializers(data=request.data,instance=book_obj)         if bs.is_valid():             bs.save() # update             return Response(bs.data)         else:             return Response(bs.errors)     def delete(self,request,pk):         models.Book.objects.filter(pk=pk).delete()           return Response("")
