net之socket的通信

Client.js:

var net = require('net');var client = new net.Socket();client.setEncoding('utf8');client.connect(8431, '127.0.0.1', function () {    console.log('已连接到服务器!');    client.write('你好.');});client.on('data', function (data) {    console.log('已收到服务器端的数据:' + data);});client.on('erro', function (err) {    console.log('与服务器连接时发生了一个错误,错误编码为:' + err.code);    client.destroy();});

Server.js:

var net = require('net');var server = net.createServer();server.on('connection',function (socket) {    console.log('客户端与服务器端链接已建立');    socket.setEncoding('utf8');    socket.on('data',function (data) {        console.log('已接收客户端发送的数据:'+data);        socket.write('确认数据:'+data)    });});server.listen(8431,'127.0.0.1');
