javascript - actionscript p2p - 聊天如何创建多个连接并向所有/任何连接发送消息

Question

我是 ActionScript 新手。今天我写了这部分代码和奇怪的事情，但它有效)))

<?xml version="1.0" encoding="utf-8"?>

        private const SERVER_ADDRESS:String = "rtmfp://p2p.rtmfp.net/bla-bla/";
        private var nc:NetConnection;
        private var ss:NetStream; 
        private var rs:NetStream; 
        private var myPeerID:String; 
        private var recvStreams:Object = new Object();
        private var sendStreams:Object = new Object();
        private var soundNewMsg:Class;



        private function initConnection():void{
            nc = new NetConnection();
            nc.maxPeerConnections = 1000;
            nc.addEventListener(NetStatusEvent.NET_STATUS, ncStatus);
            nc.connect(SERVER_ADDRESS);
        }

        public function ncStatus(event:NetStatusEvent):void{
            if(event.info.code == "NetConnection.Connect.Success"){
                myPeerID = nc.nearID;
                initSendStream();
                ExternalInterface.call("alert",nc.nearID);
            }
            else ExternalInterface.call("p2pError",event.info.code);
        }

        private function initSendStream():void{
            ss = new NetStream(nc, NetStream.DIRECT_CONNECTIONS);
            ss.publish('chat');
            var client:Object = new Object();
            client.onPeerConnect = function(subscriber:NetStream):Boolean{
                if(!sendStreams[subscriber.farID]&&!recvStreams[subscriber.farID]){
                    initReceiveStream(subscriber.farID);
                    sendStreams[subscriber.farID] = true;
                }
                return true;
            };
            ss.client = client;
        }

        private function initReceiveStream(peerID:String):void{
            rs = new NetStream(nc,peerID);
            rs.play('chat');
            var client:Object = new Object();
            client.receiveSomeData = receiveSomeData;
            rs.client = client;
            recvStreams[peerID] = true;
        }

        private function sendSomeData(str:String):void{
            if(str)ss.send('receiveSomeData', str);
        }

        private function receiveSomeData(str:String):void{
            ExternalInterface.call("receiveSomeData", str);
        }

        public function init():void{
            ExternalInterface.addCallback("initConnection",initConnection);
            ExternalInterface.addCallback("sendSomeData",sendSomeData);
            ExternalInterface.addCallback("initReceiveStream",initReceiveStream);
            ExternalInterface.call("p2pStartInit");
        }
    ]]>
</mx:Script>

js:

function getP2p(){
    if(navigator.appName.indexOf("Microsoft")!=-1)return window.p2p;
    else return document.p2p;
}

function p2pStartInit(){
    try{getP2p().initConnection()}
    catch(e){p2pError('flasherror')}
}

function initReceiveStream(p2pId){
    try{getP2p().initReceiveStream(p2pId)}
    catch(e){p2pError(e)}
}

function sendSomeData(str){
    try{getP2p().sendSomeData(str)}
    catch(e){p2pError('flasherror')}
}

function p2pError(err){
    alert(err)
}

function receiveSomeData(str,id){
    alert('Received:'+str+'/'+id)
}

和 html:

<input onblur="initReceiveStream(this.value)" value="initReceiveStream(p2pId)" />
<input onblur="sendSomeData(this.value)" value="sendSomeData(str)" />

现在我正在做什么:

我在歌剧中打开的第一个例子。它给了我它的ID。 然后我在 mozilla 中打开第二个。在第一个输入字段中，我输入了歌剧示例的 id。它连接得很好。当我尝试在这两个示例之间发送/接收消息后，一切正常(它们都接收/发送消息)

这是我的第一个问题:

当我在其他浏览器中打开第三个示例并将第三个示例 id 放入第二个示例(位于 mozilla 中)的输入字段中时，然后在 Opera 中我得到“NetStream.Connect.Closed”。如果我尝试从 mozilla 示例发送一些消息，则该消息将同时出现在 Opera 和第三个浏览器中。但如果我尝试从 Opera 发送消息，它不会发送到任何地方。我应该怎么做才能将来自 Opera 的消息发送到 Mozilla 并将来自 Mozilla 的消息发送到所有示例？

第二个问题是:

当我成功完成第一个示例时，我希望第二个示例(应包含所有已连接聊天的 ID)可以选择应将消息发送到的位置:发送到第一个示例，还是第三个示例，还是同时发送到这两个示例？我怎样才能实现这一目标？

非常感谢您的帮助!

实际上我刚刚知道如何做到这一点。
