Node | Express简单使用

npm i express@4.17.1

// 1、导入Express模块
const express = require('express')
// 2、创建web服务器
const server = express()
// 3、启动web服务器
server.listen(80, () => {
    console.log('express server running at http://127.0.0.1');
})

server.get('/user', (req, res) => {
    res.send({
        name: '张三',
        age: 18
    })
})
server.post('/user', (req, res) => {
    res.send("这是post请求")
})

server.get('/getUserById',(req,res)=>{
    console.log('id==',req.query.id)
    res.send(req.query)
})

server.get('/user/:id/:gender', (req, res) => {
    console.log('id===', req.params.id);
    console.log('gender===', req.params.gender);
    res.send(req.params)
})

server.use(express.static('./static'))

/*如果访问不到，那么大概率是路径问题，推荐导入path模块后用join拼接路径*/
server.use(express.static(path.join(__dirname,'./static')))

server.use('/static',express.static(path.join(__dirname,'./static')))
