android - 使用 Autobahn 进行 WebSocket 通信，而不是从服务器接收

Question

我正在实现 Autobahn 以通过 WebSockets 连接到服务器。当我点击连接时，它会正确打开套接字并记录该套接字已打开。然后我尝试向服务器发送一个请求，这很简单{"request":"getSoftwareVersion"}，当服务器收到这个请求时，它应该以 JSON 对象的形式发回软件版本，问题是，onMessage 永远不会被命中。这是我的代码：

public class AutoBahnConnectRequest extends Request{
    private static WebSocketConnection mAutoBahnConnection;
    private String mSocketHostAddress;
    private final static String m_TAG = AutoBahnConnectRequest.class.getSimpleName();

    public AutoBahnConnectRequest(String SocketHostAddress){
        this.mAutoBahnConnection = new WebSocketConnection();
        this.mSocketHostAddress = SocketHostAddress;
    }

    @Override
    protected Void doInBackground(Void... params){
        try {
            mAutoBahnConnection.connect(mSocketHostAddress, new WebSocketHandler(){

                @Override
                public void onOpen() {
                    String requestSoftware = "{\"request\":\"getSoftwareVersion\"}";
                    Log.i(m_TAG, requestSoftware);
                    Log.i(m_TAG, "Status: Connected to " + mSocketHostAddress);
                    mAutoBahnConnection.sendTextMessage(requestSoftware);
                }

                @Override
                public void onTextMessage(String payload) {
                    Log.i(m_TAG, "Got echo: " + payload);
                }

                @Override
                public void onClose(int code, String reason) {
                    Log.i(m_TAG, "Connection lost."+ reason);
                }
            });
        } catch (WebSocketException e) {
            Log.d(m_TAG, e.toString());
        }
        return null;
    }
}

这已经用一个像这样的 html 客户端实现了（不是用高速公路）：

function getSoftwareVersion() {
    socket_di.send('{"request":"getSoftwareVersion"}');
}

并且 onMessage 接收数据。如果我在这里做错了什么，有人可以告诉我吗？

谢谢你。

我已经弄清楚了我的问题。WebSocket 连接需要添加协议和选项。所以我改变了这个：

mAutoBahnConnection.connect(mSocketHostAddress, new WebSocketHandler(){

                @Override
                public void onOpen() {
                    String requestSoftware = "{\"request\":\"getSoftwareVersion\"}";
                    Log.i(m_TAG, requestSoftware);
                    Log.i(m_TAG, "Status: Connected to " + mSocketHostAddress);
                    mAutoBahnConnection.sendTextMessage(requestSoftware);
                }

                @Override
                public void onTextMessage(String payload) {
                    Log.i(m_TAG, "Got echo: " + payload);
                }

                @Override
                public void onClose(int code, String reason) {
                    Log.i(m_TAG, "Connection lost."+ reason);
                }
            });
        } catch (WebSocketException e) {
            Log.d(m_TAG, e.toString());
        }

对此：

 mAutoBahnConnection.connect(mSocketHostAddress,new String[]{"this is my protocol"} ,new WebSocketHandler(){

                @Override
                public void onOpen() {
                    String requestSoftware = "{\"request\":\"getSoftwareVersion\"}";
                    Log.i(m_TAG, requestSoftware);
                    Log.i(m_TAG, "Status: Connected to " + mSocketHostAddress);
                    mAutoBahnConnection.sendTextMessage(requestSoftware);
                }

                @Override
                public void onTextMessage(String payload) {
                    Log.i(m_TAG, "Got echo: " + payload);
                }

                @Override
                public void onRawTextMessage(byte[] payload) {
                    try {
                        rawText = new String(payload, "UTF-8");
                        Log.i(m_TAG, "ON RAW TEXT");
                    } catch (UnsupportedEncodingException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void onBinaryMessage(byte[] payload) {
                    Log.i(m_TAG, "ON BINARY MESSAGE");
                }


                @Override
                public void onClose(int code, String reason) {
                    Log.i(m_TAG, "Connection lost."+ reason);
                }
            }, options);
        } catch (WebSocketException e) {
            Log.d(m_TAG, e.toString());
        }
