未处理的承诺拒绝:错误:当我在JavaFX上的WebView中加载Youtube视频时不受信任的URL

WebEngine engine = webView.getEngine();
engine.setCreatePopupHandler(param -> {
    WebView newWebView = new WebView();
    webView.getChildren().add(newWebView);
    return new WebEngine();
});

engine.setOnStatusChanged(event -> {
    if (event.getSource() instanceof WebEngine) {
        WebEngine webEngine = (WebEngine) event.getSource();
        String url = webEngine.getLocation();
        if (!isTrustedUrl(url)) {
            webEngine.getLoadWorker().cancel();
        }
    }
});

private boolean isTrustedUrl(String url) {
    // 检查URL是否在信任的白名单中
    // 返回true表示受信任，允许加载；返回false表示不受信任，拒绝加载
}

WebEngine engine = webView.getEngine();
engine.setJavaScriptEnabled(true);
engine.setUserAgent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3");
engine.load(url);
