nazimGT

hello, i don't know what is happening to my Qt
i have to get a JSON file from a request to Google Maps API Geocoding, when i send a request using QNetworkAccessManager, it shown in the consol reply->size() == 0 so there is no file returned
but when i load it in a web Page with QWebEngineView pageWeb->load(QUrl(url2)); i can se the JSON file

i don't know why it not work by a request and it work in a web page

this is the code :

QUrl url2 ("https://maps.googleapis.com/maps/api/geocode/json?address="+adresse + ",+Algérie&key="+MY_API_KEY);
QNetworkRequest request;
request.setUrl(url2);
m_pNetworkAccessManager->get(request);
connect(m_pNetworkAccessManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinished(QNetworkReply*)));

pageWeb->load(QUrl(url2));
pageWeb->show();

void MainWindow::replyFinished(QNetworkReply *reply)
{
    std::cerr << (reply->size()) << endl;

    QJsonDocument document = QJsonDocument::fromJson(reply->readAll());
    QJsonObject rootObj = document.object();

    if(rootObj.empty())
        ui->statusBar->showMessage("vide");
    else
        ui->statusBar->showMessage("ayah machi vide !!!");
}
