Node.js Socket 服务端和客户端

Node.js Socket 服务端和客户端

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

/**

 * User: Administrator
 * Date: 12-10-26
 * Time: 下午3:44

 */

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

/**

 * User: Administrator

 */

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');

});
