主要代码是这样的： var net = require(“net”); var events = require(“events”); var channel = new events.EventEmitter(); channel.clients = {}; channel.subscriptions = [];

channel.on('join’,function(id,client){ console.log(‘has joined’); this.clients[id] = client; this.subscriptions[id] = function(senderid,message){ if (id != senderid) { this.clients[id].write(message); } } this.on('broadcast’,this.subscriptions[id]); });

var server = net.createServer(function(client){ var id = client.remoteAddress + “:” +client.remotePort; client.on('connect’,function(){ console.log(‘connect’); channel.emit('join’,id,client); });

client.on('data',function(data){
    data = data.toString();
    console.log('received data--->:'+data);
    channel.emit('broadcast',id,data);
});

}); server.listen(3000); 测试的时候，发现加粗的代码没有执行，查了nodejs的api，net.socket是有connect事件的，不知道为啥没执行
