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:
varnet=require('net'); varchatServer=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) functionbroadcast(message,client){ varcleanup=[]; for(vari=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
nodechat.js
连接方式:telnet
telnet127.0.0.19000
