信任过期的证书[重复]

Question

我的客户端在与证书过期的 https 服务器通信时出现以下错误。当我们正在等待通过更新在服务器端修复它时，我想知道我们是否可以通过将过期的证书添加到我们自己的信任库来绕过这个错误？这使我们能够在等待证书更新时获得一些测试时间。

使用以下代码信任所有证书。 注意：不要在生产中使用它

    try {
        SSLContext ctx = SSLContext.getInstance("TLS");
        ctx.init(new KeyManager[0], new TrustManager[] { new X509TrustManager() {
            @Override
            public void checkClientTrusted(X509Certificate[] x509Certificates, String name) throws CertificateException {}

            @Override
            public void checkServerTrusted(X509Certificate[] x509Certificates, String name) throws CertificateException {}

            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        } }, new SecureRandom());

        SSLContext.setDefault(ctx);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
