Question

我试图通过WebSocket库 socket.io 连接网址（ wws：//www.abc.com/ws？sid = sessionId0＆amp; mobile = 1 ）在android中。我用android 5.1手机测试。我收到以下错误“io.socket.engineio.client.EngineIOException：xhr poll error”

注意：我研究过socket.io库不支持来自棒棒糖设备的 wws 安全连接。

 String url = "wws://www.abc.com/ws?sid=sessionId0&mobile=1";

 mSocket = IO.socket(url);
 mSocket.on(Socket.EVENT_CONNECT, onConnect);
 mSocket.on(Socket.EVENT_DISCONNECT, onDisconnect);
 mSocket.on(Socket.EVENT_CONNECT_ERROR, onConnectError);
 mSocket.on(Socket.EVENT_CONNECT_TIMEOUT, onConnectError);
 mSocket.connect();




private Emitter.Listener onConnect = new Emitter.Listener() {
        @Override
        public void call(Object... args) {
            Log.e(TAG, "socket is connected");
            if (!isConnected) {
                if (null != mUsername)
                    mSocket.emit("add user", mUsername);
                isConnected = true;
            }
        }
    };

    private Emitter.Listener onDisconnect = new Emitter.Listener() {
        @Override
        public void call(Object... args) {

            isConnected = false;
            Log.e(TAG, "SOCKET is disconnected");
        }
    };


    private Emitter.Listener onConnectError = new Emitter.Listener() {
        @Override
        public void call(Object... args) {
            Log.e(TAG, "error occurred while connecting to socket");
        }
    };

如何解决我的问题。建议将不胜感激。在此先感谢：）
