当码头服务器上的客户端身份验证失败时，浏览器上会出现空白屏幕

Question

我使用嵌入式码头服务器创建了一个 Java rest API 并启用了客户端身份验证。在客户端身份验证中，我获取客户端证书的 CN 并查看它是否是允许的。我创建了一个过滤器 class 来处理上述客户端身份验证逻辑。但是，当客户端身份验证失败并且过滤器为 returns 时，没有任何响应被发回并且浏览器上出现空白屏幕，从那里点击 API。理想情况下，它应该响应一些错误。我正在从已经添加了有效客户端证书的浏览器中点击 API

在过滤器的响应对象中，我已经在响应中添加了一个return状态和一些其他的东西来让它结束请求但是没有用。

Enabling client auth which configuring SslContextFactory:

SslContextFactory sslContextFactory = new SslContextFactory();
sslContextFactory.setKeyStore(keyStore);
sslContextFactory.setKeyStorePassword("changeit");
sslContextFactory.setKeyManagerPassword("changeit");
sslContextFactory.setCertAlias("selfsignlatest");
sslContextFactory.setNeedClientAuth(true);
sslContextFactory.setTrustStore(keyStore);
sslContextFactory.setTrustStorePassword("changeit");

Filter class doFilter method:

@Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        logger.debug("Filtering incoming request....");
        boolean isValid = false;
        HttpServletRequest httpreq = (HttpServletRequest) request;
        HttpServletResponse httpresp = (HttpServletResponse) response;
        X509Certificate[] certificates = (X509Certificate[]) httpreq.getAttribute("javax.servlet.request.X509Certificate");
        if(certificates!=null && certificates.length>0) {
            for(X509Certificate cert: certificates) {
                commanName = getCNfromDomainName(cert.getSubjectX500Principal().getName());
                if(commanName!=null && commanName.equals("clientjetty")) {
                    isValid = true;
                    break;
                }
            }
        }

        if(isValid) {
            chain.doFilter(request, response);
        }else {
            httpresp.reset();
            httpresp.setHeader("Connection", "close");
            httpresp.setStatus(HttpStatus.SC_UNAUTHORIZED);
            httpresp.flushBuffer();
            httpresp.sendError(-1);
            return;
        }
    }

替换...

httpresp.reset();
httpresp.setHeader("Connection", "close");
httpresp.setStatus(HttpStatus.SC_UNAUTHORIZED);
httpresp.flushBuffer();
httpresp.sendError(-1);

与...

httpresp.setHeader("Connection", "close");
httpresp.sendError(HttpStatus.SC_UNAUTHORIZED);
