QtWebEngine，如何在C++/Qt6.2.4中保存饼干？

Question

因为我把应用程序的Qt5改成了Qt6，

什么对Qt5有效(为了保存cookies，我跟踪了这个线程QT 5.6 QWebEngine doesn't save cookies)，

现在不管用了：

    QWebEngineProfile::defaultProfile()->setPersistentCookiesPolicy(QWebEngineProfile::ForcePersistentCookies);
    QWebEngineProfile* defaultProfile = QWebEngineProfile::defaultProfile();

    defaultProfile->setHttpCacheType(QWebEngineProfile::DiskHttpCache);
    defaultProfile->setPersistentCookiesPolicy(QWebEngineProfile::ForcePersistentCookies);
    QHttpPart* header = new QHttpPart;
    header->setRawHeader("X-Frame-Options", "ALLOWALL");

    defaultProfile->setCachePath(QStandardPaths::writableLocation(QStandardPaths::CacheLocation));
    defaultProfile->setPersistentStoragePath(QStandardPaths::writableLocation(QStandardPaths::AppLocalDataLocation));

我要救饼干。

解决办法是：

    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);
