Qt Websocket，連接到服務器

Question

我正在嘗試連接到“ wss：//api.huobi.pro/ws”。 連接后，我必須用消息“ {“ id”：“ wanbtc”，“ sub”：“ market.wanbtc.depth.step0”}“訂閱頻道

    auto ws = new WebSocketSync;
    ws->setIs_display_scan_speed(new bool(false));

    QJsonObject json;
    json["sub"] = "market.wanbtc.depth.step0";
    json["id"] = "wanbtc";

    ws->set_url("wss://api.huobi.pro/ws");
    ws->set_register_message(QJsonDocument(json).toJson(QJsonDocument::Compact));

    ws->open();

代碼結果：

[Websocket] Current soket state: QAbstractSocket::ConnectingState
[Websocket] Current soket state: QAbstractSocket::ConnectedState
[Websocket] Connected to server "wss://api.huobi.pro/ws"
[Websocket] Send message to server "{\"id\":\"wanbtc\",\"sub\":\"market.wanbtc.depth.step0\"}"

但是socket之后不發送任何數據

類似的代碼可在node.js上運行

const moment = require('moment');
const WebSocket = require('ws');
const pako = require('pako');

const WS_URL = 'wss://api.huobi.pro/ws';


var orderbook = {};

exports.OrderBook = orderbook;

function handle(data) {
    console.log('received', data.ch, 'data.ts', data.ts, 'crawler.ts', moment().format('x'));
    let symbol = data.ch.split('.')[1];
    let channel = data.ch.split('.')[2];
    switch (channel) {
        case 'depth':
            orderbook[symbol] = data.tick;
            //console.log(data.tick);
            break;
    }
}

function subscribe(ws) {
    var symbols = ['wanbtc'];

    for (let symbol of symbols) {
        var message = JSON.stringify({
            "sub": `market.${symbol}.depth.step0`,
            "id": `${symbol}`
        });
        console.log('send to ws ' + message);
        ws.send(message);
    }

}

function init() {

    var ws = new WebSocket(WS_URL);
    ws.on('open', () => {
        console.log('connect to ' + WS_URL);
        subscribe(ws);
    });
    ws.on('message', (data) => {
        let text = pako.inflate(data, {
            to: 'string'
        });
        let msg = JSON.parse(text);
        if (msg.tick) {
            // console.log(msg);
            handle(msg);
        }

    });
}

init();

可能是什么原因？ 在node.js上工作，而不在Qt上工作。 是否需要找到QWebsocket的替代產品？

編輯1： WebSocketSync.cpp

WebSocketSync::WebSocketSync()
{
    connect(&m_socket, &QWebSocket::connected, this, [=]{

        qDebug() << "[Websocket] Connected to server" << m_socket.request().url().toString();

        if (m_is_need_to_register_channel) {

            qDebug() << "[Websocket] Send message to server" << m_register_message;
            m_socket.sendTextMessage(m_register_message);
        }

    });

    connect(&m_socket, &QWebSocket::textMessageReceived, this, [=](const QString & message) {
        qDebug() << message;
    });

}

void WebSocketSync::set_url(const QString &url)
{
//    qDebug() << "[Websocket] Server url setted:" << url;

    m_url.setUrl(url);
}

void WebSocketSync::set_register_message(const QString &url)
{
//    qDebug() << "[Websocket] Register message setted:" << url;

    m_is_need_to_register_channel = true;
    m_register_message = url;
}

void WebSocketSync::open()
{
//    qDebug() << "[Websocket] Open url:" << m_url;

    m_socket.open(m_url);
}

原因是服務器發送了二進制數據。 我需要為此連接使用QWebSocket::binaryMessageReceived 。 現在我需要弄清楚如何處理二進制數據（\\ x1F \\ x8B \\ b \\ x00 \\ x00）
