使用Nodejs是如此简单的实现了一个简单的聊天服务器

实现代码如下：

var net = require('net');

var chatServer = net.createServer(),clientList = [];

chatServer.on("connection",function(client){

client.name = client.remoteAddress + ":" + client.remotePort;

client.write("Hi! "+client.name+" \n");

clientList.push(client);

client.on("data",function(data){

//数据发送给客户端

broadcast(data,client);

// clientList[i].write(data);

});

client.on("end",function(){

clientList.splice(clientList.indexOf(client),1);

});

client.on("error",function(e){

console.log(e)

});

});

chatServer.listen(9000)

function broadcast(message,client){

var cleanup = [];

for(var i=0;i

if(client != clientList[i]){

if(clientList[i].writable){

clientList[i].write(client.name = "says:"+message);

}else{

cleanup.push[clientList[i]];

clientList[i].destory();

}

}

}

}

使用过程就是：

启动js

node chat.js

连接方式：telnet

telnet 127.0.0.1 9000
