Node.js实现简单聊天服务器

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<clientList.length;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
