> 用于取消某些資源的加載，比如css，images 使用ResourceHandler，您可以確定是否應加載HTML，圖像，JavaScript和CSS文件，favicon等資源。默認情況下，將加載所有資源。要修改默認行為，您需要注冊自己的ResourceHandler實現。例如： ``` NetworkService networkService = browser.getContext().getNetworkService(); networkService.setResourceHandler(new ResourceHandler() { @Override public boolean canLoadResource(ResourceParams params) { boolean isNotAnImageType = params.getResourceType() != ResourceType.IMAGE; if (isNotAnImageType) { return true; } // Cancel loading of all images return false; } }); ``` 此實現取消了所有圖像的加載。使用相同的技術，您可以實現并注冊自己的 ResourceHandler ，您可以在其中取消所需資源的加載。 ``` import com.teamdev.jxbrowser.chromium.*; import com.teamdev.jxbrowser.chromium.swing.BrowserView; import javax.swing.*; import java.awt.*; /** * This sample demonstrates how to handle all resources such as * HTML, PNG, JavaScript, CSS files and decide whether web browser * engine should load them from web server or not. For example, in * this sample we cancel loading of all Images. */ public class ResourceHandlerSample { public static void main(String[] args) { Browser browser = new Browser(); BrowserView browserView = new BrowserView(browser); JFrame frame = new JFrame(); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.add(browserView, BorderLayout.CENTER); frame.setSize(700, 500); frame.setLocationRelativeTo(null); frame.setVisible(true); NetworkService networkService = browser.getContext().getNetworkService(); networkService.setResourceHandler(new ResourceHandler() { @Override public boolean canLoadResource(ResourceParams params) { System.out.println("URL: " + params.getURL()); System.out.println("Type: " + params.getResourceType()); boolean isNotImageType = params.getResourceType() != ResourceType.IMAGE; if (isNotImageType) { return true; // Cancel loading of all images } return false; } }); browser.loadURL("http://www.google.com"); } } ```
