使用JxBrowser DialogHandler API可以处理应显示“ 选择SSL证书”对话框的情况。默认情况下，JxBrowser显示其自己的对话框实现，用户可以在可用证书列表中选择所需的证书。为了覆盖默认行为，您必须使用重写的DialogHandler.onSelectCertificate（CertificatesDialogParams params）方法注册您自己的DialogHandler接口实现。在您的实现中，您可以显示自己的对话框或取消对话框并以编程方式选择所需的证书。 以下示例演示如何使用自定义“选择SSL证书”对话框覆盖默认实现： ``` import com.teamdev.jxbrowser.chromium.*; import com.teamdev.jxbrowser.chromium.swing.BrowserView; import com.teamdev.jxbrowser.chromium.swing.DefaultDialogHandler; import javax.swing.*; import java.awt.*; import java.util.List; /** * The sample demonstrates how to display Select SSL Certificate dialog where * user must select required SSL certificate to continue loading web page. */ public class SelectSSLCertificateSample { public static void main(String[] args) { Browser browser = new Browser(); final BrowserView view = new BrowserView(browser); JFrame frame = new JFrame(); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.add(view, BorderLayout.CENTER); frame.setSize(700, 500); frame.setLocationRelativeTo(null); frame.setVisible(true); browser.setDialogHandler(new DefaultDialogHandler(view) { @Override public CloseStatus onSelectCertificate(CertificatesDialogParams params) { String message = "Select a certificate to authenticate yourself to " + params.getHostPortPair().getHostPort(); List<Certificate> certificates = params.getCertificates(); if (!certificates.isEmpty()) { Object[] selectionValues = certificates.toArray(); Object selectedValue = JOptionPane.showInputDialog(view, message, "Select a certificate", JOptionPane.PLAIN_MESSAGE, null, selectionValues, selectionValues[0]); if (selectedValue != null) { params.setSelectedCertificate((Certificate) selectedValue); return CloseStatus.OK; } } return CloseStatus.CANCEL; } }); browser.loadURL("<URL that causes Select SSL Certificate dialog>"); } } ```
