使用 express 框架搭建 web 服务
首先创建工程目录
代码语言：javascript复制~ $ mkdir myapp
~/myapp $ cd myapp初始化nodejs工程

Is this OK? (yes) 安装 express 框架
代码语言：javascript复制~/myapp $ npm install express写个Hello World验证程序
代码语言：javascript复制const express = require('express')
const app = express()
const port = 3000
app.get('/', (req, res) => {
res.send('Hello World!')
})
app.listen(port, () => {
console.log(`Example app listening on port ${port}`)
})启动服务
代码语言：javascript复制~/myapp $ node app.js
Example app listening on port 3000使用浏览器访问 http://192.168.31.250:3000/ 验证。
