关于DRF基类APIView提供的Request和Response对象的作用，可以看我的另一篇博文：

综合使用：

from django.http import HttpResponsefrom rest_framework import statusfrom rest_framework.response import Responsefrom rest_framework.views import APIViewfrom user.models import Departmentfrom user.serializers import DepartmentSerializerclass DepartmentListAPIView(APIView):    def get(self,request):        """查询多条数据"""        dep = Department.objects.all()        # 创建序列化器对象        serializer = DepartmentSerializer(instance=dep,many=True)        # 序列化：对象->字典        data_dict = serializer.data        # DRF的Response对象可以把字典转换为请求头指定的格式返回        return Response(data=data_dict)    def post(self,request):        """新增一条数据"""        # DRF的Request对象直接把接受到的值转换为字典        data_dict = request.data        # 创建序列化器对象        serializer = DepartmentSerializer(instance=None,data=data_dict)        # 校验校验不通过，抛异常(反序列化的功能)        serializer.is_valid(raise_exception=True)        # 反序列化，把字典的数据存进数据库        serializer.save()        # restful风格，新增要返回新增数据的那一列内容。用了序列化，把对象转换为字典，同时Response处理。        return Response(data=serializer.data)class DepartmentDetailAPIView(APIView):    def get(self,request,pk):        """查询一条数据"""        # 查询出该条数据的对象        try:            dep = Department.objects.get(id=pk)        except Department.DoesNotExist:            return HttpResponse(status=status.HTTP_404_NOT_FOUND)        # 创建序列化器对象        serializer = DepartmentSerializer(instance=dep)        # 序列化，把对象转换为字典，同时Response根据请求头返回相应的格式        return Response(data=serializer.data)    def post(self,request,pk):        """修改部门"""        # DRF的Request对象直接把接受到的值转换为字典        data_dict = request.data        # 查询出要修改的数据        try:            dep = Department.objects.get(id=pk)        except Department.DoesNotExist:            return HttpResponse(status=404)        # 创建序列化器对象        serializer = DepartmentSerializer(instance=dep,data=data_dict)        # 反序列化，校验参数是否正确，若不正确，抛异常        serializer.is_valid(raise_exception=True)        # 反序列化，把字典的数据存进数据库        serializer.save()        # 序列化，把对象转换为字典。同时DRF的Response对象根据请求头返回相应的格式        return Response(serializer.data)    def delete(self,request,pk):        """删除一个部门"""        try:            dep = Department.objects.get(id=pk)        except Department.DoesNotExist:            return HttpResponse(status=404)        dep.delete()        return Response(status=status.HTTP_204_NO_CONTENT)

 

相应路由的配置：

urlpatterns = [    url(r'^admin/', admin.site.urls),    url(r'^departments$',views.DepartmentListAPIView.as_view()),    url(r'^departments/(?P
     
      \d+)$',views.DepartmentDetailAPIView.as_view())]
