目前我正在使用 flex 和 FMS（Flash 媒体服务器）进行客户端和服务器端通信。
我正在尝试执行以下程序，该程序每 2 秒检查一次连接状态，如果客户端没有响应则断开连接。

这里我收到一个错误：
ReferenceError：错误 #1069：在 flash.net.NetConnection 上找不到属性 ping，并且没有默认值。

客户端代码

        nc.connect("rtmp://127.0.0.1/ChkConn",user.text);

服务器端代码

 // ActionScript Communications Document
 application.onAppStart=function()
 {
trace("Application Start");
 };
application.onConnect=function(client,name)
{
anyvariable=name;

monitorConnection(client);
if(name!="user1")
{
    application.rejectConnection(client);
    trace(name+" Rejected");
}
else
{
application.acceptConnection(client);
trace(name+" Connect"); 
}

 };

clientPingResponder = function(client) {

this.onResult = function(res) {
    trace("ClientPingResponder.onResult Received: " + res);
    clearInterval(client.cleanupTaskId);
} 

this.onStatus = function(info) {
    trace("ClientPingResponder.onStatus Received: " + info);
}
};
monitorConnection = function(client) {

client.isAlive = function() {
    trace("client.isAlive has been fired");
    client.cleanupTaskId = setInterval(client.dead, 2 * 1000);
    client.call("pings", new clientPingResponder(client));
}

client.dead = function() {
    trace("cleanupTaskId: " + client.cleanupTaskId);
    trace("monitorTaskId: " + client.monitorTaskId);

    clearInterval(client.cleanupTaskId);
    clearInterval(client.monitorTaskId);

    trace("ghost connection has been detected");

    application.disconnect(client);
}

client.monitorTaskId = setInterval(client.isAlive, 7*1000);
trace("detected");
}


application.onDisconnect=function(client)
{
//application.disconnect(client);
trace(anyvariable +" Disconnect");
};

任何帮助都会得到帮助。谢谢

你需要类似的东西。

nc.client = this;
