Cookies值未在QWebEngineView中传播

Question

我正在尝试使用QWebEngineProfile，QWebEnginePage和QWebEngineCookieStore使用QWebEngineView打开一个jsp文件。我可以为从应用程序发起的呼叫设置Cookie。但是随后会启动多个jsp调用，但未为该调用设置cookie。 代码截图如下。

QWebEngineSettings* webEngineSettings = QWebEngineSettings::defaultSettings();                webEngineSettings->setAttribute(QWebEngineSettings::WebAttribute::AutoLoadImages, true);        webEngineSettings->setAttribute(QWebEngineSettings::WebAttribute::JavascriptEnabled, true);                         webEngineSettings->setAttribute(QWebEngineSettings::WebAttribute::LocalStorageEnabled, true);

QWebEngineProfile* profile = new QWebEngineProfile("abc", parent);
profile->setPersistentCookiesPolicy(QWebEngineProfile::AllowPersistentCookies);
profile->setHttpCacheType(QWebEngineProfile::HttpCacheType::MemoryHttpCache);
profile->setHttpCacheMaximumSize(10);
QWebEngineCookieStore* cookieStore = profile->cookieStore();
cookieStore->loadAllCookies();
QNetworkCookie* webEngineNewCookie = new NetworkCookie(QByteArray("MyCookie"), QByteArray("1234"));
QUrl url = "https://example.com/help.jsp"
cookieStore->setCookie(*webEngineNewCookie, QUrl(url));
QStringList location = QStandardPaths::standardLocations(QStandardPaths::CacheLocation);
profile->setPersistentStoragePath(location.at(0));

QWebEnginePage* page = new QWebEnginePage(profile,parent);
page->action(QWebEnginePage::WebAction::InspectElement);

QWebEngineHttpRequest* webEngineHttpReq = new QWebEngineHttpRequest(QUrl(url), QWebEngineHttpRequest::Post);
parent->setPage(page);
parent->load(*webEngineHttpReq);

当我进行此调用时，我确实在此（https://example.com/help.jsp）中获得了cookie，但是此后从help.jsp启动了另一个调用，这些调用可能没有cookie，因此它们被服务器。
