Using Nodejs is so simple to implement a simple chat server
The implementation code is as follows:
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){ //Send data to client 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(); } } }}The process of use is:
Start js
node chat.js
Connection method: telnet
telnet 127.0.0.1 9000
