### 案例-使用APIView改写RestAPI ###

# views.py from rest_framework.views import APIView from rest_framework import status from django.http import Http404 from booktest.serializers import BookInfoSerializer # /books/ class BookListView(APIView): """ 获取所有图书、增加图书 """ def get(self, request): """ 获取所有的图书数据 """ queryset = BookInfo.objects.all() # 序列化所有图书数据 serializer = BookInfoSerializer(queryset, many=True) return Response(serializer.data) def post(self, request): """ 新增一个图书数据 """ # 反序列化-数据校验 serializer = BookInfoSerializer(data=request.data) serializer.is_valid(raise_exception=True) # 反序列化-数据保存(save内部会调用序列化器类的create方法) serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) # /books/(?P<pk>\d+)/ class BookDetailView(APIView): """ 获取、修改、删除指定图书 """ def get(self, request, pk): """ 获取指定图书 """ try: book = BookInfo.objects.get(pk=pk) except BookInfo.DoesNotExist: raise Http404 # 将图书数据进行序列化 serializer = BookInfoSerializer(book) return Response(serializer.data) def put(self, request, pk): """ 修改指定图书 """ try: book = BookInfo.objects.get(pk=pk) except BookInfo.DoesNotExist: raise Http404 # 反序列化-数据校验 serializer = BookInfoSerializer(book, data=request.data) serializer.is_valid(raise_exception=True) # 反序列化-数据保存(save内部会调用序列化器类的update方法) serializer.save() return Response(serializer.data) def delete(self, request, pk): """ 删除指定图书： """ try: book = BookInfo.objects.get(pk=pk) except BookInfo.DoesNotExist: raise Http404 book.delete() return Response(status=status.HTTP_204_NO_CONTENT)
