Router使用

• router.js

const express  =require('express'); //导入express
const router = express.Router();//2.创建路由对象

//3.挂载具体路由

router.get('/user/list',(req,res)=>{
    res.send('Get user list...');
    console.log('获取用户信息....');
});//http://127.0.0.1/api/user/list

router.get('/user/add',(req,res)=>{
    res.send('Add user list...');
    console.log('添加用户信息....')
});//http://127.0.0.1/api/user/add


//4.向外暴露路由对象
module.exports =router;

• index.js

const express =require('express');//1.导入express

const router = require('./router');//2.导入路由模块

const app = express();

app.use('/api',router);//3.注册路由模块，并加上统一的前缀

app.listen(80,()=>{console.log('http://127.0.0.1已经启动！')})
