我搜索了 Google、FMS Guru 和大量 Adob​​e 开发人员教程。我有点困惑如何从客户端将变量作为参数发送到共享对象或客户端对象中，以便我可以从 main.asc 文件中获取和处理服务器端的变量。

例如，如何使用创建的 SWF 中的 AS3 将用户名、用户 ID、性别、用户类型和生日变量发送到 main.asc 文件？

来自chat.mxml

private var xmlstring:String = "http://www.blah.com/xml.xml";


            private var userType:String;
            private var userCountText:String;

            protected function getXML():void {
                XML.ignoreWhitespace = true;
                var myLoader:URLLoader=new URLLoader();
                myLoader.load(new URLRequest(ownerstring));
                myLoader.addEventListener(Event.COMPLETE, processXML);
            }

            protected function processXML(e:Event):void {
                var myXML:XML = XML(e.target.data)
                for (var i:int = 0; i<myXML.*.length(); i++){
                    xinstance = myXML.owner[0];
                    xuserid = myXML.owner[1];
                    xusername = myXML.owner[2];
                    xphoto = myXML.owner[3];
                    xroomowner = myXML.owner[4];
                }
                //xinstance = myXML.broadcastowner.owner.(@title == "instance");
                //xuserid = myXML.broadcastowner.owner.(@title == "userid");
                //xusername = myXML.broadcastowner.owner.(@title == "username");
                //xphoto = myXML.broadcastowner.owner.(@title == "photo");
                //xroomowner = myXML.broadcastowner.owner.(@title == "roomowner");

                go();
            }

            private function initConnection(event:FlexEvent):void{
                getXML();
            }

            private function go():void {
                var fmsstring:String = "rtmp://blah.com/appname/" + xinstance;

                nc = new NetConnection();
                nc.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
                nc.connect(fmsstring);
                nc.client = this;
            }           

            protected function onNetStatus(event:NetStatusEvent):void{
                trace(event.info.code);

                switch(event.info.code){

                    case "NetConnection.Connect.Success":
                        publishCamera(); 
                        displayPublishingVideo();
                        chat_broadcastLive();

                        so = SharedObject.getRemote("message", nc.uri, false);

                        so.username = xusername;
                        so.userid = xuserid;
                        so.userType = xroomowner;

                        so.addEventListener(SyncEvent.SYNC, soOnSync);
                        so.client = this;
                        so.connect(nc);

                        //so.setProperty("userinfo",{username:xusername, userid:xuserid, userType:xroomowner});

                        sendBtn.addEventListener(MouseEvent.CLICK, onClickSendBtn);
                        break;

                    case "NetConnection.Connect.Closed" :
                        nc.call("chat.sendMessage", myResponder, xusername + " left the room");
                        break;

                }
            }

主目录

application.onAppstart = function(){
this.totalUserCount = 0; 
}

application.onConnect = function(client, username, userid, gender, userType, birthday )
{

//userType = so.data.userinfo["userType"];

client.username = username;
client.userid = userid;
client.gender = gender;
client.userType = userType;
client.birthdaye = birthday;

if(userType="viewer"){
this.totalUserCount++;
}

client.chat = chat;

application.acceptConnection(client);

}

application.onDisconnect = function(client){
if(userType="viewer"){
this.totalUserCount--;
}
}

trace("usercount is:" + this.totalUserCount);

使用上面的 main.asc 代码我得到“usercount is undefined”，所以我一定做错了什么。

至少您的一个问题是您将值“viewer”分配给您的 userType var 而不是评估它。例如

if(userType="viewer")

应该

if(userType == "viewer")

此外，您的跟踪语句很可能在您应用程序 onStart() 之前运行，因此您的变量在那时确实是未定义的。

在您的客户端代码中，您需要在连接字符串之后在网络连接上的 connect() 函数中传递参数，所以如果它会是这样的：

nc.connect(fmsstring, username, userid, gender, userType, birthday);
