Save Cookies in Qt6.2.4 ?

[Paullux]

    qDebug(qPrintable(QStandardPaths::writableLocation(QStandardPaths::CacheLocation)));
    qDebug("\n");
    qDebug(qPrintable(QStandardPaths::writableLocation(QStandardPaths::AppLocalDataLocation)));

return :

C:/Users/paulw/AppData/Local/Paul_WOISARD/FranceTV/cache


C:/Users/paulw/AppData/Local/Paul_WOISARD/FranceTV

but the folders don't exist in my system

I meant before and after setting the path on the default profile.

The problem is existing since i upgrade to Qt6.2.3 or Qt6.2.4, before with Qt5.15.2 ou Qt5.15.6 i havent its problem

[SGaist]

That I understood very well. Hence I suggested that you compare the values of the cache path before and after you set it on the profile in order to eliminate that as an obvious possible bug.

in doc i found this :

    QNetworkAccessManager *manager = new QNetworkAccessManager(this);
    QNetworkDiskCache *diskCache = new QNetworkDiskCache(this);
    diskCache->setCacheDirectory(QStandardPaths::writableLocation(QStandardPaths::CacheLocation));
    manager->setCache(diskCache);

which save cache but no cookies

for your question

    qDebug("before");
    qDebug(qPrintable(QWebEngineProfile::defaultProfile()->persistentStoragePath()));

...
...
...
    qDebug("after");
    qDebug(qPrintable(QWebEngineProfile::defaultProfile()->persistentStoragePath()));

result :

before
qt.webenginecontext:
...
...
...
after
C:/Users/paulw/AppData/Local/Paul_WOISARD/FranceTV

@SGaist

the responses to your question is here :

    qDebug("before");
    qDebug(qPrintable(QWebEngineProfile::defaultProfile()->cachePath()));
    qDebug(qPrintable(QWebEngineProfile::defaultProfile()->persistentStoragePath()));
    defaultProfile->setCachePath(QStandardPaths::writableLocation(QStandardPaths::CacheLocation));
    defaultProfile->setPersistentStoragePath(QStandardPaths::writableLocation(QStandardPaths::AppLocalDataLocation));
    qDebug("after");
    qDebug(qPrintable(QWebEngineProfile::defaultProfile()->cachePath()));
    qDebug(qPrintable(QWebEngineProfile::defaultProfile()->persistentStoragePath()));

reponse :

before

C:/Users/paulw/AppData/Roaming/Paul_WOISARD/FranceTV/QtWebEngine/OffTheRecord
after

C:/Users/paulw/AppData/Local/Paul_WOISARD/FranceTV

cachePath is never set

[SGaist]

Looks like you found the culprit.

Can you check with 6.3 ?

Looks like you found the culprit.

with qt6.2.3 it's the same

CachePath: ""
StoragePath: "C:/Users/paulw/AppData/Roaming/Paul_WOISARD/FranceTV/QtWebEngine/OffTheRecord"
isOffTheRecord: true
after
CachePath: ""
StoragePath: "C:/Users/paulw/AppData/Local/Paul_WOISARD/FranceTV"
isOffTheRecord: true

perhaps cache size must be define

[Paullux]

the problem with qt6.3.0 is always here

[SGaist]

Then you should check the bug report system to see if there already something about it. If not, please open a new report providing a minimal compilable example that shows that behaviour.

i created a ticket issue : https://bugreports.qt.io/browse/QTBUG-102133

[Paullux]

its not mean be a bug.

a developer of Qt said me :
Michal Klocek a ajouté un commentaire - Il y a 2 heures
in 6.x series default profile is off the record , you need to create a custom profile and use that.

how to create a profile which is on the record ?

[SGaist]

Unless I am mistaken you got an answer to that as well on the report.

[Paullux]

The Solution is :

    QWebEngineProfile *profile = new QWebEngineProfile(QString::fromLatin1("MyApplication.%1").arg(qWebEngineChromiumVersion()));  // unique profile store per qtwbengine version
    QWebEnginePage *page = new QWebEnginePage(profile); // page using profile
    QWebEngineView *view = new QWebEngineView();

    view->setPage(page);
    view->setUrl(AccueilUrl);
    view->setZoomFactor(1.2);

    setCentralWidget(view);
