如何重新连接断开的连接

Question

由于互联网连接速度慢，我正在重新连接用户连接，用户断开连接后。我需要让用户连接回去。问题是，连接成功，并且重新连接正在完成，但同一用户重新连接时，它将作为新的连接添加到fms服务器。以下是用于简单连接和重新连接的柔性代码。

      <![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>&nbsp;</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>&nbsp;</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>&nbsp;</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>

FMS代码（main.asc的）

 var name="connect"; 
     application.onAppStart=function() 
     { 
     trace("ON connected");

     application.onConnect=function(client)

     trace("connected::::: "+name); 

     client.disconnectClient=function()

     client.getdata=function(str) 
     { 
     name=str; 
     trace("GetData Is Called!! "+name); 
     }; 

     }; 


     application.onDisconnect=function() 
     { 
     trace("Disconnected: "); 
     }; 

请让我知道，我缺乏的背后我在哪里。如果提供任何示例，这将是非常有帮助的。

在此先感谢

你是对的，每个NetConnection到FMS服务器获取独特的FMS标识，并没有什么，你可以做的。但是，你必须要考虑，当你使用命令连接到FMS：

nc.connect(connectionURL, "user1"); 

你已经确定你的用户到服务器。唯一剩下的部分是接收服务器端脚本这样的信息：

application.onConnect = function(client, userId) 
{ 
    // userId will contain "user1" 
} 

然后你就可以收集连接的用户在服务器端脚本的信息，并确定新的连接是新用户或重联现有的用户。

干杯！
