Django REST framework视图

Django REST framework视图 学习序列化的时候发现有大量的冗余代码，所以我们要使用Django REST framework里的视图减少我们的代码 DRF中的request 在Django REST Framework中内置的Request类扩展了Django中的Request类，实现了很多方便的功能--如请求数据解析和认证等。 比如，区别于Django中的request从request.GET中获取URL参数，从request.POST中取某些情况下的POST数据。 在APIView中封装的request，就实现了请求数据的解析： 对于GET请求的参数我们通过request.query_params来获取。 对于POST请求、PUT请求的数据我们通过request.data来获取。 学习序列化时的部分 from rest_framework.views import APIView from rest_framework.response import Response from .models import * from django.shortcuts import HttpResponse from django.core import serializers from rest_framework import serializers class
