JS
//1. 引入express
const express = require('express');
//2. 创建应用对象
const app = express();
//3. 创建路由规则
// request 是对请求报文的封装
// response 是对响应报文的封装
//jQuery 服务
app.all('/jquery-server', (request, response) => {
//设置响应头 设置允许跨域
response.setHeader('Access-Control-Allow-Origin', '*');
response.setHeader('Access-Control-Allow-Headers', '*');
// response.send('Hello jQuery AJAX');
const data = {name:'尚硅谷'};
response.send(JSON.stringify(data));
});
//4. 监听端口启动服务
app.listen(8000, () => {
console.log("服务已经启动, 8000 端口监听中....");
});
