Question

我有一台服务器，如果我使用node.js和javascript，我会完美地连接到它并接收消息。

我在Android Studio上启动了一个具有EditText和TextView属性的应用。

我的目标是输入EditText按发送并将该消息发送到服务器并在TextView中打印回复。

出于某种原因，我无法让它工作，我可以看到Socket在我调试它时会连接。但我似乎无法从我的js示例中获得服务器的响应。这是我的代码：

public class MainActivity extends AppCompatActivity {
    private Socket socket;
    String response = "";
    BufferedReader in = null;
    PrintStream out = null;
    TextView tv;
    EditText et;
    private static final int SERVERPORT = 80;
    private static final String ONLY_HOST = "myServer.azurewebsites.net";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv = (TextView) findViewById(R.id.textView);
        et = (EditText) findViewById(R.id.messages);

        ClientThread client = new ClientThread();
        client.execute();


    }

    class ClientThread extends AsyncTask<Void, Void, Void> {
        @Override
        protected Void doInBackground(Void... arg0) {
            try {

                socket = new Socket(ONLY_HOST, SERVERPORT);
                byte[] buffer = new byte[1024];
                InputStream inputStream = socket.getInputStream();

                while (inputStream.read(buffer) != -1) {
                    response += new String(buffer);
                }
            } catch (UnknownHostException e1) {
                Log.e("UnknownHost","Socket not starting" );
                e1.printStackTrace();
            } catch (IOException e1) {
                Log.e("IO Exception","Socket not starting" );
                e1.printStackTrace();
            }
            return null;
        }
        @Override
        protected void onPostExecute(Void result) {
            if (tv != null) {
                tv.setText(response);
            }
            super.onPostExecute(result);
        }
    }


    public void sendIt(View v)  {
        try {
            if (socket.isConnected()) {
                out = new PrintStream(socket.getOutputStream(), true);
                out.write(et.getText().toString().getBytes());
                out.flush();

            }
        } catch (UnknownHostException e1) {
            Log.e("sendIt","1st" );
            e1.printStackTrace();
        } catch (IOException e1) {
            Log.e("sendIt","2nd" );
            e1.printStackTrace();
        }
    }
}

任何帮助都会让我已经这么久了。

谢谢！
