Question

您好我有一个服务器套接字，它侦听来自客户端套接字的请求，而我的代码似乎无法从客户端套接字发送的数据中检索其输入流中的数据。

下面是侦听连接和处理请求的服务器套接字代码

  public void startlistener() {
serverSocket = new ServerSocket(PORT);
            listening = true;
            thread.start();
            Log.print(TAG, "startlistener");

        }

        public void stopListener() {
            thread.stop();
            listening = false;
            Log.print(TAG, "stopListener");
        }

    public void run() {
                while (listening) {
                    try {

                        Log.d(TAG, "inside server listener loop");
                        Socket accept = serverSocket.accept();

                        String data = getData(accept);

                        httpHandler.handleRequest(data, accept);

                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }

    private String getData(Socket socket) throws IOException {
            InputStream in = socket.getInputStream();
            Log.print(TAG, "getData");
            int c = 0;

            StringBuffer buffer = new StringBuffer();
    //goes as far as here and then freezes/doesnt retrieve anything from the input stream
            while ((c = in.read()) != -1) {
                buffer.append((char) c);
            }
            return buffer.toString();

        }

这是我的测试用例

private static final String HTTP_REQUEST = "HTTP/1.0 408 Request Time-out"
        + newLine + "Cache-Control: no-cache" + newLine
        + "Connection: close" + newLine + "Content-Type: text/html";

public void testSocketConnection() {

        try {
            httpProxy = new HttpProxy(testHttpHandler);
            httpProxy.startlistener();
            testSocket = new Socket("localhost", HttpProxy.PORT);
            OutputStream outputStream = testSocket.getOutputStream();
            InputStream inputStream = testSocket.getInputStream();

            outputStream.write(HTTP_REQUEST.getBytes());
} catch (UnknownHostException e) {
            httpProxy.stopListener();
            e.printStackTrace();
            fail(e.toString());
        } catch (IOException e) {
            httpProxy.stopListener();
            e.printStackTrace();
            fail(e.toString());
        }


}

您的客户端未关闭套接字。您的服务器读取套接字直到EOS，因为您的客户端没有关闭套接字，所以它永远不会到达。

NB不接受接受线程中的客户端I / O.开始一个单独的线程。

Java Socket服务器无法从客户端套接字接收数据
