如何忽略来自 Java 应用程序外部的过期证书?

Anyone have any ideas that would work?

推荐答案

这里是结合java - 忽略过期的 ssl 证书 和 Java SSL:如何禁用主机名验证.

public class IgnoreExpiredServerCertificateAgent {

    public static void premain(String args, Instrumentation inst) throws Exception {
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init((KeyStore) null);

        TrustManager[] trustManagers = tmf.getTrustManagers();
        final X509TrustManager origTrustManager = (X509TrustManager) trustManagers[0];

        TrustManager[] wrappedTrustManagers = new TrustManager[]{
                new X509TrustManager() {
                    @Override
                    public X509Certificate[] getAcceptedIssuers() {
                        return origTrustManager.getAcceptedIssuers();
                    }

                    @Override
                    public void checkClientTrusted(X509Certificate[] certs, String authType) throws CertificateException {
                        origTrustManager.checkClientTrusted(certs, authType);
                    }

                    @Override
                    public void checkServerTrusted(X509Certificate[] certs, String authType) throws CertificateException {
                        try {
                            origTrustManager.checkServerTrusted(certs, authType);
                        } catch (CertificateExpiredException ignored) {
                        }
                    }
                }
        };

        //SSLContext sc = SSLContext.getDefault();
        SSLContext sc = SSLContext.getInstance("TLS");
        sc.init(null, wrappedTrustManagers, null);
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    }
}

然后只需将 -javaagent:IgnoreExpiredServerCertificateAgent.jar 添加到程序的 java 启动参数中.
