Node.js實現簡單聊天伺服器_node.js

使用Nodejs是如此簡單的實現了一個簡單的聊天伺服器

實現代碼如下：

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){    //資料發送給用戶端    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();      }    }  }}

使用過程就是：

啟動js

node chat.js

串連方式：telnet

telnet 127.0.0.1 9000
