由于互联网连接速度慢，用户断开连接后，我正在重新连接用户连接。我需要让用户连接回来。问题是，连接成功，并且重新连接正在完成，但重新连接时，同一用户，它在fms服务器上添加为新连接。下面是简单连接和重新连接的flex代码。

<![CDATA[<p><b>Stream Reconnect</b></p>
<p>This example shows how a stream continues to play even when you lose your network connection.
The stream uses the buffer to continue playing while the NetConnection is reconnected.</p>
<p> </p>
<p><b>Do one of the following to disconnect and reconnect to a nework:</b>
<li>Disable your wireless network connection and enable it.</li>
<li>Unplug your ethernet cable and plug it back in.</li>
<li>Unplug your ethernet cable and try to connect to a wireless connection.</li></p>
<p><b>Or, to simulate a network change, click the Disconnect button.</b></p>
<p>The Disconnect button calls the application.disconnect() function on the server.
(If you call NetConnection.close() on the client, Flash Player cleans up the NetConnection
and NetStream objects and you can't reuse them.)</p>
<p> </p>
<p>The stream continues to play seamlessly. Watch the log to see the 'NetConnection.Connect.Closed' event,
then 'Timer Started', then either 'reconnectNetConnection() called' or 'NetConnection.Connect.Failed'.
If the connection attempt fails, the timer runs again and restarts the process until a successful
connection is made. A successful connection triggers 'NetConnection.Connect.Success' which invokes
'reconnectStream()'</p>
<p> </p>
<p><b>Smart Seek</b></p>
<p>Smart seek uses the back buffer and the forward buffer to seek -- the server doesn't request
data from the server. Click "Show Buffers" to see the buffer lengths. Click "Seek" and "Step" to move
the playhead. Look at the log to see whether the seek was "Smart" or "Standard". If the buffer isn't large
enough, Flash Player calls the server for more data, resulting in a standard seek. </p>

你是对的，每个NetConnection到FMS服务器获得一个唯一的FMS ID，你无能为力。但是，当您使用以下命令连接到FMS时必须考虑：
nc.connect(connectionURL, "user1");
您已经确定了服务器的用户身份。唯一剩下的部分是在服务器端脚本中接收此信息：
application.onConnect = function(client, userId)
{
// userId will contain "user1"
}
然后，您可以在服务器端脚本中收集已连接用户的信息，并确定新连接是新用户还是重新连接现有用户。
干杯！
