如何重新連接斷開的連接

Question

由於互聯網連接速度慢，我正在重新連接用戶連接，用戶斷開連接後。我需要讓用戶連接回去。問題是，連接成功，並且重新連接正在完成，但同一用戶重新連接時，它將作爲新的連接添加到fms服務器。以下是用於簡單連接和重新連接的柔性代碼。

      <![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代碼（main.asc的）

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

     application.onConnect=function(client)

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

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

     }; 


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

請讓我知道，我缺乏的背後我在哪裏。如果提供任何示例，這將是非常有幫助的。

在此先感謝

你是對的，每個NetConnection到FMS服務器獲取獨特的FMS標識，並沒有什麼，你可以做的。但是，你必須要考慮，當你使用命令連接到FMS：

nc.connect(connectionURL, "user1"); 

你已經確定你的用戶到服務器。唯一剩下的部分是接收服務器端腳本這樣的信息：

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

然後你就可以收集連接的用戶在服務器端腳本的信息，並確定新的連接是新用戶或重聯現有的用戶。

乾杯！
