工作 50 分钟后 POCO websocket 混乱

Question

我有以下与 POCO 库相关的问题。我的客户使用 POCO 库监听来自我们后端服务器的消息。前 50 分钟一切正常，然后套接字发生了一些奇怪的事情，方法“receiveFrame”开始返回异常。之后，套接字将无法运行。我做了一些测试，之后我收到无法运行的套接字的时间正好是 50 分钟。另外我需要注意的是，我们的后端服务器始终不会发送任何内容。我不知道会发生什么...下面是我们的握手和读取程序的代码：

void WebSocketManager::Handshake()
{
    qDebug() << "WebSocketManager::Handshake";

    try {
        HTTPResponse response;
        QString origin = Settings::Instance()->GetErPortal();
        QString host = origin.remove("http://");
        host = host.remove('/');
        QString token = "/event/bus/ws/subscribe?auth_token=" + Settings::Instance()->token().toUtf8();

        _wssession.setHost(host.toUtf8().constData());
        _wssession.setPort(80);

        HTTPRequest request(HTTPRequest::HTTP_GET, token.toUtf8().constData(),HTTPMessage::HTTP_1_1);
        request.set("origin", origin.toUtf8().constData());

        _wssock = new WebSocket(_wssession, request, response);
        response.getStatus();

        HTTPResponse::HTTPStatus status = response.getStatus();
        qDebug() << "Handshake status is : " << status;

        if(status == HTTPResponse::HTTPStatus::HTTP_SWITCHING_PROTOCOLS)
            _status = true;
    }
    catch (std::exception &e)
    {
        qDebug() << "WebSocketManager::Handshake exception " << e.what();
    }
}

void WebSocketManager::Read()
{
    char receiveBuff[1024];

    while(_status)
    {

        qDebug() << "WebSocketManager::Read wait data...., thread = " << QThread::currentThread();

        try {
            int flags=0;
            int rlen=_wssock->receiveFrame(receiveBuff,1024,flags);

            if(!rlen)
            {
                qDebug() << "WebSocketManager::Read error";
                emit ConnectionFailed();
                return;
            }
            else
            {
                qDebug() << "WebSocketManager::Read, len =" << rlen << ", flags = " << flags << ", data = " << receiveBuff;
                ProcessBackendEvent(QString(receiveBuff));
            }
        }
        catch (std::exception &e)
        {
            qDebug() << "WebSocketManager::Read exception " << e.what();
        }

    }
}

这似乎是这里描述的 POCO 库的错误https://github.com/pocoproject/poco/issues/490 在 1.9.0 POCO 库上一切正常...
