Question

我尝试从Android应用/客户端连接到socket.io，但我一直收到以下错误

io.socket.engineio.client.EngineIOException：xhr民意调查错误

从服务器端（如后端人员所说），这是连接的代码

var socket = require('socket.io-client')('https://al3malh-geniusescode.c9users.io:8081', {
query: {
    "session_key": '52c3cf92-34d8-4edd-8809-94679533a1c6'
}
});

socket.on('connection', function () {});

从android方面来看，（在持有代码的活动的onCreate方法中）代码是：

public Socket socket;
IO.Options options = new IO.Options();

JSONObject jsonObject = new JSONObject();



 try {
            jsonObject.put("session_key",readFromPreferences(MyApplication.getAppContext(), MyApplication.SESSION_KEY, ""));
    } catch (JSONException e) {
        e.printStackTrace();

    }

        options.query = jsonObject.toString();

{
            try {

            socket = IO.socket("https://al3malh-geniusescode.c9users.io:8081",options);



        } catch (URISyntaxException e) {
            e.printStackTrace();
        }
    }



socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {
@Override
public void call(Object... args) {

    Log.d("ActivityName: ", "CONNECTION");
}
});

    socket.on(Socket.EVENT_CONNECTING, new Emitter.Listener() {
        @Override
        public void call(Object... args) {

            Log.d("ActivityName: ", "Trying To Connect");


        }
    });

    socket.on(Socket.EVENT_CONNECTING, new Emitter.Listener() {
        @Override
        public void call(Object... args) {

            Log.d("ActivityName: ", "Trying To Connect");


        }
    });



    socket.on("on_error", new Emitter.Listener() {
        @Override
        public void call(Object... args) {

            Log.d("ActivityName: ", "ERROR FROM SERVER"+args[0].toString());

        }
    });
    socket.on(Socket.EVENT_CONNECT_ERROR,new Emitter.Listener() {
        @Override
        public void call(Object... args) {

            Log.d("ActivityName: ", args[0].toString());

        }
    });
    socket.connect();

我正在使用的图书馆是

＆＃39; io.socket：socket.io客户端：0.7.0＆＃39;

并且清单中有权限（INTERNET）。

来自查询的问题是我在（Options.query）中作为字符串传递的吗？

任何帮助都将得到高度评价，在此先感谢

无法从Android客户端连接到socket.io，服务器需要查询＆＃39;
