})

const express = require("express");               //加载express
 
const ppp = express.Router();                       //运行router

ppp.get("/user/list", (req, res) => {              //简单的路由
    res.send(‘用户列表‘)
})

ppp.post("/user/add", (req,res) => {           //简单的路由
    res.send(‘添加用户‘)
})
module.exports = ppp;                                 //共享对象

const express = require("express");               

const app = express();

const ly = require("./03_模块化对象分支");

app.use(ly);    //注册路由模块     (必须要)

app.listen(80, () => {
