Node.js net

net-socket 聊天室效果

1. server.js 先创建个服务器

```javascriptconst net = require('net');const port = 8080;const hostname = '10.31.163.20';const server = ateServer();const clients = {};let clinenum = ('connection', (client) => {  //连接客户端client.name = ++clinenum           //不同客户端编号clients[client.name] = ('data', (msg) => {       //获取客户端发来的信息console.log(`客户端${client.name}发来信息>${msg}`)for (let key in clients) {clients[key].write(`客户端${client.name}发来信息>${msg}`)}})('error', (e) => {console.log(`错误是${e}`)});('close', (clineName) => {   //客户端下线，提示信息delete clients[client.name]console.log(`客户端${client.name}已下线`)});});server.listen(port, hostname, () => {   //监听服务器console.log(`server is running at:${hostname}:${port}`)})
```

2. client.js 创建客户端

        const net = require('net');const socket = new net.Socket();const port = 8080;const hostname = '10.31.163.20';const readline = require('readline');const rl = ateInterface({ // 创建接口，进行信息的读写input: process.stdin,output: process.stdout})t(port, hostname, () => {socket.write('大家好')})('data', () => {rl.question('请输入', (answer) => {if (answer === 'bye') {          //如果输入bye就关闭客户端socket.destroy()rl.end()} else {socket.write(answer + 'n')}})})('error', (e) => {console.log(`错误是${e}`)});('close', () => {console.log('客户端已下线')})
   

首先运行server.js，然后可以运行多个client.js模拟多个客户端操作
