Java GUI显示网页并返回HTML

Java GUI显示网页并返回HTML

这是一个使用JavaFX的人为示例，该示例将html内容打印到System.out
－适应创建

getHtml()

方法应该不会太复杂。（我已经用JavaFX 8对其进行了测试，但是它也应该可以与JavaFX 2一起使用）。

每次加载新页面时，该代码都会打印HTML内容。

注意：我已

printdocument

从此答案中借用了代码。

public class TestFX extends Application {    @Override    public void start(Stage stage) throws Exception {        try { final WebView webView = new WebView(); final WebEngine webEngine = webView.getEngine(); Scene scene = new Scene(webView); stage.setScene(scene); stage.setWidth(1200); stage.setHeight(600); stage.show(); webEngine.getLoadWorker().stateProperty().addListener(new ChangeListener<Worker.State>() {     @Override     public void changed(Observablevalue<? extends State> ov, State t, State t1) {         if (t1 == Worker.State.SUCCEEDED) {  try {      printdocument(webEngine.getdocument(), System.out);  } catch (Exception e) { e.printStackTrace(); }         }     } }); webView.getEngine().load("http://www.google.com");        } catch (Exception e) { e.printStackTrace();        }    }    public static void printdocument(document doc, OutputStream out) throws IOException, TransformerException {        TransformerFactory tf = TransformerFactory.newInstance();        Transformer transformer = tf.newTransformer();        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");        transformer.setOutputProperty(OutputKeys.METHOD, "xml");        transformer.setOutputProperty(OutputKeys.INDENT, "yes");        transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");        transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");        transformer.transform(new DOMSource(doc), new StreamResult(new OutputStreamWriter(out, "UTF-8")));    }    public static void main(String[] args) {        launch(args);    }}
