Django 和 Restful API

Django 和 Restful API：构建现代化的Web应用程序

python
# 引入Django和Rest Framework相关模块
from django.urls import path
from rest_framework.views import APIView
from rest_framework.response import Response
# 定义资源视图类
class UserView(APIView):
    def get(self, request):
        # 处理GET请求，返回用户列表
        users = User.objects.all()
        response_data = []
        for user in users:
            response_data.append({
                'id': user.id,
                'name': user.name,
                'email': user.email
            })
        return Response(response_data)
    
    def post(self, request):
        # 处理POST请求，创建新用户
        name = request.data.get('name')
        email = request.data.get('email')
        user = User.objects.create(name=name, email=email)
        return Response({'id': user.id, 'name': user.name, 'email': user.email})
    
    def put(self, request, user_id):
        # 处理PUT请求，更新指定用户
        name = request.data.get('name')
        email = request.data.get('email')
        user = User.objects.get(id=user_id)
        user.name = name
        user.email = email
        user.save()
        return Response({'id': user.id, 'name': user.name, 'email': user.email})
    
    def delete(self, request, user_id):
        # 处理DELETE请求，删除指定用户
        user = User.objects.get(id=user_id)
        user.delete()
        return Response(status=204)
# 定义URL路由
urlpatterns = [
    path('users/', UserView.as_view()),
    path('users//', UserView.as_view()),
