本文實例講述了nodejs socket實現的服務端和客戶端功能。分享給大家供大家參考，具體如下：

使用node.js的net模塊能很快的開發出基于TCP的服務端和客戶端。直接貼代碼。

server.js

/** * Created with JetBrains WebStorm. * User: Administrator * Date: 12-10-26 * Time: 下午3:44 * To change this template use File | Settings | File Templates. */var net = require('net');var timeout = 20000;//超時var listenPort = 7003;//監聽端口var server = net.createServer(function(socket){  // 我們獲得一個連接 - 該連接自動關聯一個socket對象  console.log('connect: ' +    socket.remoteAddress + ':' + socket.remotePort);  socket.setEncoding('binary');  //超時事件//  socket.setTimeout(timeout,function(){//    console.log('連接超時');//    socket.end();//  });  //接收到數據  socket.on('data',function(data){    console.log('recv:' + data);  });  //數據錯誤事件  socket.on('error',function(exception){    console.log('socket error:' + exception);    socket.end();  });  //客戶端關閉事件  socket.on('close',function(data){    console.log('close: ' +      socket.remoteAddress + ' ' + socket.remotePort);  });}).listen(listenPort);//服務器監聽事件server.on('listening',function(){  console.log("server listening:" + server.address().port);});//服務器錯誤事件server.on("error",function(exception){  console.log("server error:" + exception);});

client.js

/** * Created with JetBrains WebStorm. * User: Administrator * Date: 12-10-26 * Time: 下午3:56 * To change this template use File | Settings | File Templates. */var net = require('net');var port = 7003;var host = '127.0.0.1';var client= new net.Socket();client.setEncoding('binary');//連接到服務端client.connect(port,host,function(){  client.write('hello my client');});client.on('data',function(data){  console.log('recv data:'+ data);});client.on('error',function(error){  console.log('error:'+error);  client.destory();});client.on('close',function(){  console.log('Connection closed');});

希望本文所述對大家nodejs程序設計有所幫助。
