QT 5.8 Webview如何执行请求，如何拦截它？

QWebEngineView *webView = new QWebEngineView();
webView->load(QUrl("https://www.example.com"));

void requestInterceptor(QWebEngineHttpRequest &request) {
    // 在这里对请求进行拦截或修改
    qDebug() << "Intercepted request: " << request.url().toString();
}

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);

    QWebEngineView *webView = new QWebEngineView();
    QWebEngineProfile *profile = webView->page()->profile();
    profile->setRequestInterceptor(requestInterceptor);

    webView->load(QUrl("https://www.example.com"));
    webView->show();

    return app.exec();
}
