QWebEngineView的信号为void loadStarted()。它从QWebEnginePage收到时会发出此信号。 QWebEnginePage从QWebEnginePagePrivate重写此函数,其中它是void loadStarted(const QUrl& provisionalUrl,bool isErrorPage = false),但在QWebEnginePage类参数中,参数provisionalUrl标记为Q_UNUSED(),但我想知道它的值。我该怎么办?

如果你必须截取导航请求并按导航类型过滤它们,你可以做的最好是覆盖QWebEnginePage :: acceptNavigationRequest()虚函数。
https://doc.qt.io/qt-5/qwebenginepage.html#acceptNavigationRequest
class NavigationRequestOverride : public QWebEnginePage
{
public:
NavigationRequestOverride(QObject* parent) : QWebEnginePage(parent) {}
protected:
virtual bool acceptNavigationRequest(const QUrl &url, NavigationType type, bool isMainFrame)
{
// Here goes your logic
}
};
