默认情况下，JxBrowser允许使用无效的SSL证书加载HTTPS网站。如果您需要更改此默认行为并且不允许无效的SSL证书，则可以在您决定是否应忽略无效SSL证书的情况下注册自己的LoadHandler实现。例如： ``` browser.setLoadHandler(new DefaultLoadHandler() { @Override public boolean onCertificateError(CertificateErrorParams params) { // Return false to ignore certificate error. return false; } }); ``` 该 CertificateErrorParams 参数提供了有关SSL证书无效信息。您可以使用其详细信息来决定是否允许证书。 ``` import com.teamdev.jxbrowser.chromium.Browser; import com.teamdev.jxbrowser.chromium.Certificate; import com.teamdev.jxbrowser.chromium.CertificateErrorParams; import com.teamdev.jxbrowser.chromium.DefaultLoadHandler; import com.teamdev.jxbrowser.chromium.swing.BrowserView; import javax.swing.*; import java.awt.*; /** * Demonstrates how to handle SSL certificate errors. */ public class CertificateErrorSample { 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); browser.setLoadHandler(new DefaultLoadHandler() { @Override public boolean onCertificateError(CertificateErrorParams params) { Certificate certificate = params.getCertificate(); System.out.println("subjectName = " + certificate.getSubjectName()); System.out.println("issuerName = " + certificate.getIssuerName()); System.out.println("hasExpired = " + certificate.hasExpired()); System.out.println("errorCode = " + params.getCertificateError()); // Return false to ignore certificate error. return false; } }); browser.loadURL("<https-url-with-invalid-ssl-certificate>"); } } ```
