使用node.js的net模块能很快的开发出基于TCP的服务端和客户端。直接贴代码。
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;//超时 var listenPort = 7003;//监听端口 var server = net.createServer(function(socket){ // 我们获得一个连接 - 该连接自动关联一个socket对象 console.log('connect: ' + socket.remoteAddress + ':' + socket.remotePort); socket.setEncoding('binary'); //超时事件 // socket.setTimeout(timeout,function(){ // console.log('连接超时'); // socket.end(); // }); //接收到数据 socket.on('data',function(data){ console.log('recv:' + data); }); //数据错误事件 socket.on('error',function(exception){ console.log('socket error:' + exception); socket.end(); }); //客户端关闭事件 socket.on('close',function(data){ console.log('close: ' + socket.remoteAddress + ' ' + socket.remotePort); }); }).listen(listenPort); //服务器监听事件 server.on('listening',function(){ console.log("server listening:" + server.address().port); }); //服务器错误事件 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'); //连接到服务端 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'); });
