use this code...

QNetworkAccessManager* netManager = new QNetworkAccessManager();
        QUrl myurl("http://******");
        QNetworkRequest req(myurl);

    QNetworkReply* ipReply = netManager->get(req);

    QEventLoop eventLoop;
    QObject::connect(ipReply, SIGNAL(finished()), &eventLoop, SLOT(quit()));
    eventLoop.exec();
    std::cout << "finished" << std::endl; //request finished here
    requestFinished(ipReply);

Use QNetworkAccessManager, QNetworkRequest and QNetworkReply classes to make http connection.

QNetworkAccessManager* netManager = new QNetworkAccessManager();
QUrl myurl(yourURL);
QNetworkRequest req(url);

QNetworkReply* ipReply = netManager->get(req);
connect(ipReply, SIGNAL(finished(QNetworkReply*)), this, SLOT(onReply(QNetworkReply*)));
}

In onReply slot parse your response

if (reply) {
    if (reply->error() == QNetworkReply::NoError) {
        int available = reply->bytesAvailable();
        if (available > 0) {
            int bufSize = sizeof(char) * available + sizeof(char);
            QByteArray buffer(bufSize, 0);
            int read = reply->read(buffer.data(), available);
            response = QString(buffer);
        }
    } else {
        response =
                QString("Error: ") + reply->errorString()
                        + QString(" status:")
                        + reply->attribute(
                                QNetworkRequest::HttpStatusCodeAttribute).toString();
    }
    reply->deleteLater();
}
