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

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: ' +

console.log("server error:" + exception);
});
