java - Java Server如何向Flex打开的Socket写入数据

Question

好的，基本上我的 Flex 应用程序会打开一个套接字并监听它。我的 java 程序将向此端口写入一些字符串。

我的 AS3 代码是

        private function onRecvClick():void
        {
            var host:String = "localhost"; 
            var port:int = 9090;

            var socket:Socket = new Socket(host, port);
            socket.addEventListener(Event.CONNECT, onConnect);
            socket.addEventListener(DataEvent.DATA, onData);
            socket.connect(host, port);
        }

我的 Java 代码是:

 private ClientSocket()
{
    try
    {
        String  host    =   "localhost";
        int     port    =   9090;

        Socket socket = openSocket(host, port);

        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
        writer.write("HelloTest");
        writer.flush();

    }
    catch (Exception e)
    {
        System.out.println(e);
    }
}

private Socket openSocket(String server, int port) throws Exception
{
  Socket socket;

  // create a socket with a timeout
  try
  {
    InetAddress inteAddress = InetAddress.getByName(server);
    SocketAddress socketAddress = new InetSocketAddress(inteAddress, port);

    // create a socket
    socket = new Socket();

    // this method will block no more than timeout ms.
    int timeoutInMs = 10*1000;   // 10 seconds
    socket.connect(socketAddress, timeoutInMs);

    return socket;
  } 
  catch (SocketTimeoutException ste) 
  {
    System.err.println("Timed out waiting for the socket.");
    ste.printStackTrace();
    throw ste;
  }
}

在尝试写入套接字时，我收到此 java.net.ConnectException: Connection refused: connect。有趣的是，Flex 中的 socket 似乎没有派发任何事件，这正常吗？

除非我完全误读了文档，flash.net.Socket和 java.net.Socket是客户端套接字。

您需要将一侧作为服务器套接字才能将它们连接在一起。

对于 Java 中的服务器端，请查看此演练:Socket Communications .
