在socket io中，一個用戶連接創建了數十個「加入空間」？

Question

我在linux上連接到運行socket-io-client的客戶機上有一個nodejs socket.io應用程序。

的nosejs服務器是：

• 節點v6.7.0
• 表達4.10.8
• socket.io 1.4.5

Java端使用行家：

<dependency> 
    <groupId>io.socket</groupId> 
    <artifactId>socket.io-client</artifactId> 
    <version>0.8.3</version> 
    </dependency> 

我只是從socket.io 0.9遷移，所以我只有一個用戶連接到nodejs套接字服務器。

在某些情況下，我有一個奇怪的現象是這一個連接創建數十個連接

socket.io:socket socket connected - writing packet +106ms 
socket.io:socket joining room /#q-brvq0-lMhLKY6tAAAR +0ms

從Java客戶端這是創建連接的代碼：

 try { 
      System.out.println("socket phy create"); 
      socket = IO.socket(domain+":"+port); 
     } catch (URISyntaxException ex) { 
      System.out.println("socket URISyntaxException"); 
     } 

95它創建只有一個「套接字連接」的時間的百分比，5％創建了幾十個。有什麼問題，或者你能提出一種調試方法？

Answer 1

的問題是與系統實現..

當我調試，我有時會被關閉套接字服務器（爲了改變一些代碼）。在客戶端，我每5秒鐘進行一次重新連接檢查。這個方法每次都調用createNodeConnection。當最後我重新加載套接字服務器時，所有這些連接立即連接。

定盤到「套接字創建」從「套接字連接」分離（並使用在重連接方法的「套接字連接」）

public void createNodeConnection() { 
     try { 
      socket = IO.socket(domain+":"+port); 
     } catch (URISyntaxException ex) { 
      System.out.println("socket URISyntaxException"); 
     } 

     socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() { 
      @Override 
      public void call(Object... args) {...//handle code..} 

     }).on(Socket.EVENT_DISCONNECT, new Emitter.Listener() { 

      @Override 
      public void call(Object... args) {...//handle code..} 

     }).on(Socket.EVENT_CONNECT_ERROR, new Emitter.Listener() { 
      @Override 
      public void call(Object... args) {...//handle code..}; 
     });    

     socketConnection(); 
}; 


public void socketConnection() { 
     socket.connect();    

}
