關於DRF基類APIView提供的Request和Response物件的使用，可以看我的另一篇博文：https://www.cnblogs.com/chichung/p/9939864.html

綜合使用：

from django.http import HttpResponse
from rest_framework import status
from rest_framework.response import Response
from rest_framework.views import APIView
from user.models import Department
from
 
 user.serializers import DepartmentSerializer


class DepartmentListAPIView(APIView):
    def get(self,request):
        """查詢多條資料"""
        dep = Department.objects.all()
        # 建立序列化器物件
        serializer = DepartmentSerializer(instance=dep,many=True)
        # 序列化：物件->字典
        data_dict = serializer.data
        
 
# DRF的Response物件可以把字典轉換為請求頭指定的格式返回
        return Response(data=data_dict)

    def post(self,request):
        """新增一條資料"""
        # DRF的Request物件直接把接受到的值轉換為字典
        data_dict = request.data
        # 建立序列化器物件
        serializer = DepartmentSerializer(instance=None,data=data_dict)
        # 校驗校驗不通過，拋異常(反序列化的功能)
 

        serializer.is_valid(raise_exception=True)
        # 反序列化，把字典的資料存進資料庫
        serializer.save()
        # restful風格，新增要返回新增資料的那一列內容。用了序列化，把物件轉換為字典，同時Response處理。
        return Response(data=serializer.data)


class DepartmentDetailAPIView(APIView):
    def get(self,request,pk):
        """查詢一條資料"""
        # 查詢出該條資料的物件
        try:
            dep = Department.objects.get(id=pk)
        except Department.DoesNotExist:
            return HttpResponse(status=status.HTTP_404_NOT_FOUND)
        # 建立序列化器物件
        serializer = DepartmentSerializer(instance=dep)
        # 序列化，把物件轉換為字典，同時Response根據請求頭返回相應的格式
        return Response(data=serializer.data)

    def post(self,request,pk):
        """修改部門"""
        # DRF的Request物件直接把接受到的值轉換為字典
        data_dict = request.data
        # 查詢出要修改的資料
        try:
            dep = Department.objects.get(id=pk)
        except Department.DoesNotExist:
            return HttpResponse(status=404)
        # 建立序列化器物件
        serializer = DepartmentSerializer(instance=dep,data=data_dict)
        # 反序列化，校驗引數是否正確，若不正確，拋異常
        serializer.is_valid(raise_exception=True)
        # 反序列化，把字典的資料存進資料庫
        serializer.save()
        # 序列化，把物件轉換為字典。同時DRF的Response物件根據請求頭返回相應的格式
        return Response(serializer.data)

    def delete(self,request,pk):
        """刪除一個部門"""
        try:
            dep = Department.objects.get(id=pk)
        except Department.DoesNotExist:
            return HttpResponse(status=404)
        dep.delete()
        return Response(status=status.HTTP_204_NO_CONTENT)

相應路由的配置：

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