Node.js实现简单聊天服务器

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
