问题描述

我正在尝试使用套接字与服务器建立连接.连接管道破损如下图异常.

I am trying to make connection with server using socket. The connection pipe is broken as shown below exceptions.

这是代码，在这一行 outStreamRec.write(bData); 抛出异常.

Here is the code and on this line outStreamRec.write(bData); throwing exception.

    try {
        port = 86;
        byterecv = new byte[1040];
        clientRec = new Socket();
        clientRec.connect(new InetSocketAddress("192.168.1.36", port));
        System.out.println("Just connected to " + clientRec.getRemoteSocketAddress());
    } catch (IOException e2) {
        // TODO Auto-generated catch block
        e2.printStackTrace();
    }
    while (true) {
        try {
            System.out.println("Connecting to " + ServerUrl.url + " on port " + port);              
            OutputStream outToServerRec = clientRec.getOutputStream();
            DataOutputStream outStreamRec = new DataOutputStream(outToServerRec);

            outStreamRec.write(bData);

            InputStream inFromServerPlay = clientRec.getInputStream();
            DataInputStream inStreamPlay = new DataInputStream(inFromServerPlay);
            while ((lstream = inStreamPlay.read(byterecv)) != -1) {
                System.out.println("startrec bytearray -- " + byterecv.length);
                bos1.write(byterecv, 0, lstream);
            }                
            if (stopcall == true) {
                clientRec.close();
                break;
            }

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

注意:如果我关闭套接字连接立即工作正常.但是我想保持连接仍然活着我手动关闭套接字连接.单击停止按钮我正在关闭连接.

Note: if I close the socket connection immediate works fine. But I want to keep the connection alive still I close the socket connection manually. Onclick of stop button I am closing the connection.

我搜索了网络，但没有找到解决此问题的方法.

I searched the web, but didn't find a way to fix this.

推荐答案

对等方在您写入时关闭了连接.这通常意味着你向它发送了它不理解的东西.它可能是一个 HTTP 服务器吗?或者您尚未在客户端代码中实现的其他协议?

The peer closed the connection while you were writing to it. That usually means you sent it something it didn't understand. Is it perhaps an HTTP server? Or some other protocol that you haven't implemented in your client code?
