Rest Web Service - Keep-alive Connection



  • How to Keep-Alive Connection calling rest Web Service
    It is necessary to keep alive any TCP/HTTP while calling 2 or more Server request if so
    how to use connection:Keep-Alive , Im using that codes below:

    #include <QDebug>
    #include <QThread>
    #include <QtCore/QUrl>
    #include <QtNetwork/QNetworkAccessManager>
    #include <QtNetwork/QNetworkRequest>
    #include <QtNetwork/QNetworkReply>
    #include <QtNetwork/QNetworkProxy>
    #include <QtXml/QDomDocument>

    MainWindow::MainWindow(QWidget *parent,) :
    QDialog(parent),
    ui(new Ui::afterbarcode)
    {
    ui->setupUi(this);
    }
    MainWindow::~MainWindow()
    {
    delete ui;
    }

    void MainWindow::on_pushButton_clicked()
    {

    QString url="http://127.0.0.1:8085/";
    QString Webmethod="ValidationRequest?SessionKey=12345678";
    

    QString REQUEST_URL =url+Webmethod;

    m_network = new QNetworkAccessManager (this);
    QNetworkRequest request;

    request.setUrl(QUrl(REQUEST_URL));

    QNetworkReply *reply = m_network->get(request);
    QObject::connect(m_network, SIGNAL(finished(QNetworkReply *)),
    SLOT(RequestFinished(QNetworkReply *)));

    }

    void MainWindow::RequestFinished(QNetworkReply *reply){

    QByteArray data = reply->readAll();
    QDomDocument doc;
    doc.setContent(data);
    qDebug()<<"<XML>"<<doc.toString()<<"</XML>";
    QDomNodeList ValidationResponse = doc.elementsByTagName("ValidationResponse");
    QDomNodeList Result = doc.elementsByTagName("Result");
