＝＝＝＝＝＝＝＝＝＝＝server.js＝＝＝＝＝＝＝＝＝＝＝
//引用 express
const { request, response, json } = require('express');
const express = require('express');
//创建应用对象
const app = express();
//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
//app.all 可以接收任意类型的请求头
app.all('/axios-server', (request, response) => {
//设置响应头，设置充许跨域
response.setHeader('Access-Control-Allow-Origin', '*');
response.setHeader('Access-Control-Allow-Headers', '*');
const data = { name: 'xiaoming', age: '18' };
//setTimeout(() => {
response.send(JSON.stringify(data));
//}, 3000);
})
// 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.......');
})
