由于基础django中的View,不支持form表单传参,并且返回给前端的数据只能是json数据,所以本次优化,继承rest_framework中的APIView
请求实例方法中的第二个参数request为rest_framework中的Request对象:
request会根据请求头中的Content-Type自动解析
使用request.data可以对POST、PUT、PATCH的请求体参数进行解析,不仅支持form传参,也支持json格式传参
使用request.query_params获取查询字符串参数
views.py文件优化后的代码如下:
from rest_framework import status from rest_framework.views import APIView from rest_framework.response import Response from django.http import Http404 from .models import Projects from .serializers import ProjectsModelSerializer class ProjectsList(APIView): def get(self, request): projects = Projects.objects.all() serializer = ProjectsModelSerializer(projects, many=True) return Response(serializer.data, status=status.HTTP_200_OK) def post(self, request): serializer = ProjectsModelSerializer(data=request.data) try: serializer.is_valid(raise_exception=True) except Exception as e: return Response(serializer.errors) serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) class ProjectsDetail(APIView): def get_object(self, pk): try: return Projects.objects.get(id=pk) except Projects.DoesNotExist: raise Http404 def get(self, request, pk): project = self.get_object(pk) serialzer = ProjectsModelSerializer(project) return Response(serialzer.data, status=status.HTTP_200_OK) def put(self, request, pk): project = self.get_object(pk) serialzer = ProjectsModelSerializer(instance=project, data=request.data) try: serialzer.is_valid(raise_exception=True) except: return Response(serialzer.errors) serialzer.save() return Response(serialzer.data, status=status.HTTP_201_CREATED) def delete(self, pk): project = self.get_object(pk) project.delete() return Response(None, status=status.HTTP_204_NO_CONTENT)
projects子应用下的其它文件代码未改动,本次不再上传!
django框架学习六:优化views.py文件,使用rest_framework中的APIVew和Response返回
