基于GenericAPIView写的接口

本文主要是介绍基于GenericAPIView写的接口，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

# views.py
class Book2View(GenericAPIView):
    #queryset要传queryset对象，查询了所有的图书
    # serializer_class使用哪个序列化类来序列化这堆数据
    queryset=Book.objects
    # queryset=Book.objects.all()
    serializer_class = BookSerializer
    def get(self,request):
        book_list=self.get_queryset()
        book_ser=self.get_serializer(book_list,many=True)

        return Response(book_ser.data)
    def post(self,request):
        book_ser = self.get_serializer(data=request.data)
        if book_ser.is_valid():
            book_ser.save()
            return Response(book_ser.data)
        else:
            return Response({'status':101,'msg':'校验失败'})


class Book2DetailView(GenericAPIView):
    queryset = Book.objects
    serializer_class = BookSerializer
    def get(self, request,pk):
        book = self.get_object()
        book_ser = self.get_serializer(book)
        return Response(book_ser.data)

    def put(self, request,pk):
        book = self.get_object()
        book_ser = self.get_serializer(instance=book,data=request.data)
        if book_ser.is_valid():
            book_ser.save()
            return Response(book_ser.data)
        else:
            return Response({'status': 101, 'msg': '校验失败'})

    def delete(self,request,pk):
        ret=self.get_object().delete()
        return Response({'status': 100, 'msg': '删除成功'})
    
 #url.py
    # 使用GenericAPIView重写的
    path('books2/', views.Book2View.as_view()),
    re_path('books2/(?P<pk>\d+)', views.Book2DetailView.as_view()),
