QWebEngineProfile设置给h5权限

最近开发中遇到QWebEngine嵌入网页，控制语音的开关双击无效的问题。找到如下的解决方案：

#include <QApplication>
#include <QUrl>
#include <QWebEngineView>

class WebEnginePage: public QWebEnginePage{
    Q_OBJECT
public:
    WebEnginePage(QObject *parent = Q_NULLPTR):QWebEnginePage(parent){
        connect(this, &WebEnginePage::featurePermissionRequested, this, &WebEnginePage::onFeaturePermissionRequested);
    }
private Q_SLOTS:
    void onFeaturePermissionRequested(const QUrl &securityOrigin, QWebEnginePage::Feature feature){

//在这里设置权限
        if(feature  == QWebEnginePage::MediaAudioCapture
                || feature == QWebEnginePage::MediaVideoCapture
                || feature == QWebEnginePage::MediaAudioVideoCapture)
            setFeaturePermission(securityOrigin, feature, QWebEnginePage::PermissionGrantedByUser);
        else
            setFeaturePermission(securityOrigin, feature, QWebEnginePage::PermissionDeniedByUser);
    }
};
main函数：
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    
     关键代码如下：
     
    QString sPath = QDir::currentPath();
    sPath = sPath+"/html/test.html";
    ui.webEngineView->setPage(new WebEnginePage);
    ui.webEngineView->resize(1024, 750);
    ui.webEngineView->setUrl(sPath);
    
    return app.exec();
}
