在socket io中，一个用户连接创建了数十个“加入空间”？

Question

我在linux上连接到运行socket-io-client的客户机上有一个nodejs socket.io应用程序。

的nosejs服务器是：

• 节点v6.7.0
• 表达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> 

我只是从socket.io 0.9迁移，所以我只有一个用户连接到nodejs套接字服务器。

在某些情况下，我有一个奇怪的现象是这一个连接创建数十个连接

从Java客户端这是创建连接的代码：

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

95它创建只有一个“套接字连接”的时间的百分比，5％创建了几十个。有什么问题，或者你能提出一种调试方法？

Answer 1

的问题是与系统实现..

当我调试，我有时会被关闭套接字服务器（为了改变一些代码）。在客户端，我每5秒钟进行一次重新连接检查。这个方法每次都调用createNodeConnection。当最后我重新加载套接字服务器时，所有这些连接立即连接。

定盘到“套接字创建”从“套接字连接”分离（并使用在重连接方法的“套接字连接”）

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();    

}
