用node.js模拟服务器和客户端

var net = require("net")var server = net.createServer();server.listen(12306,"127.0.0.1") server.on("listening",function(){ ???console.log(server.address()) ???console.log("服务启动了")}) server.on(‘connection‘,function(socket){ ???console.log(‘有新的连接‘) ???socket.on(‘data‘,function(data){ ?????????console.log(data.toString()) ??????????socket.write("hello client") ????}) ???socket.on(‘close‘,function(){ ???????console.log("客户端已关闭") ???????server.close() ???})}) server.on(‘close‘,function(){ ???console.log(‘服务器已关闭‘)})

var net= require("net");var socket = net.connect(12306,"127.0.0.1")socket.on(‘connect‘,function(){ ???console.log(‘已连接服务器‘) ???console.log(socket.remoteAddress);//服务器地址 ???console.log(socket.remotePort)//服务器端口 ???console.log(socket.localAddress)//本地地址 ???console.log(socket.localPort)//本地端口})socket.on(‘data‘,function(data){ ???console.log(data.toString()) ????socket.end()})socket.on(‘close‘,function(){ ???console.log("连接已关闭")})socket.write("hello server")
