我正在使用RPi和WebRTC构建家庭安全系统。我只需要一种方法来触发浏览器在给定的URL处打开并自动授予对麦克风和摄像头的访问权限。我曾希望将WebEngine库与PyQt一起使用,但PyQt for RPi不支持WebEngine。所以我现在正在尝试Qt。不幸的是我不熟悉C ++,所以我很挣扎。
示例here占我所需要的90%。代码在下面复制。我只需要调整它就可以在请求时授予对麦克风和摄像头的访问权限。我希望有人可以帮助我吗?
#include <QApplication>
#include <QWebEngineView>
QUrl commandLineUrlArgument()
{
const QStringList args = QCoreApplication::arguments();
for (const QString &arg : args.mid(1)) {
if (!arg.startsWith(QLatin1Char('-')))
return QUrl::fromUserInput(arg);
}
return QUrl(QStringLiteral("https://www.qt.io"));
}
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QApplication app(argc, argv);
QWebEngineView view;
view.setUrl(commandLineUrlArgument());
view.resize(1024, 750);
view.show();
return app.exec();
}

我回答了这个问题,但对于PyQt5:Grant access to Cam & Mic using Python for PyQt WebEngine,我只会对Python进行C ++转换,基础是相同的。
#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){
if(feature == QWebEnginePage::MediaAudioCapture
|| feature == QWebEnginePage::MediaVideoCapture
|| feature == QWebEnginePage::MediaAudioVideoCapture)
setFeaturePermission(securityOrigin, feature, QWebEnginePage::PermissionGrantedByUser);
else
setFeaturePermission(securityOrigin, feature, QWebEnginePage::PermissionDeniedByUser);
}
};
QUrl commandLineUrlArgument()
{
const QStringList args = QCoreApplication::arguments();
for (const QString &arg : args.mid(1)) {
if (!arg.startsWith(QLatin1Char('-')))
return QUrl::fromUserInput(arg);
}
return QUrl(QStringLiteral("https://www.qt.io"));
}
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QApplication app(argc, argv);
QWebEngineView view;
view.setPage(new WebEnginePage);
view.setUrl(commandLineUrlArgument());
view.resize(1024, 750);
view.show();
return app.exec();
}
