Question

我正在尝试使用套接字与服务器建立连接。连接管坏了如下图异常。

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

    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存在我手动关闭套接字连接。单击停止按钮我将关闭连接。

我在网上搜索过，但没有找到解决此问题的方法。

在您写入时，对方关闭了连接。这通常意味着您向它发送了它不理解的内容。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一些协议(protocol)？
