Question

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

nosejs服务器是：

node v6.7.0
express 4.10.8
socket.io 1.4.5

java方面正在使用maven：

  <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了几十个连接

socket.io:socket socket connected - writing packet +106ms

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％的时间它只创建了一个＆＃34; socket connect＆＃34;和5％它创建了几十个。有什么问题或者您可以建议一种调试方法吗？

问题在于系统实施..

在我调试时，我有时会关闭套接字服务器（为了更改一些代码）。在客户端，我每5秒进行一次重新连接检查。此方法每次都调用createNodeConnection。最后我重新加载套接字服务器，所有这些连接立即连接。

修复是将'套接字创建'与'套接字连接'分开（并在重新连接方法中使用'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();            

}

在socket io中，一个用户连接创建了数十个＆＃34;加入空间＆＃34;？
