nodejs socket服务端和客户端简单通信功能

var net = require('net');//模块引入var listenPort = 8080;//监听端口var server = net.createServer(function(socket){ // 创建socket服务端 console.log('connect: ' +  socket.remoteAddress + ':' + socket.remotePort); socket.setEncoding('binary'); //接收到数据 socket.on('data',function(data){  console.log('client send:' + data); });socket.write('Hello client!/r/n'); // socket.pipe(socket); //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('client closed!');   // 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);});

var net = require('net');var port = 8080;var host = '127.0.0.1';var client= new net.Socket();//创建socket客户端client.setEncoding('binary');//连接到服务端client.connect(port,host,function(){ client.write('hello server'); //向端口写入数据到达服务端});client.on('data',function(data){ console.log('from server:'+ data); //得到服务端返回来的数据});client.on('error',function(error){//错误出现之后关闭连接 console.log('error:'+error); client.destory();});client.on('close',function(){//正常关闭连接 console.log('Connection closed');});
