Question

如果我只知道该字段的名称，如何从X509Certificate获取价值？
例如＆＃34; CN＆＃34;有OID＆＃34; 2.5.4.3＆＃34;，如果我知道只获取字符串名称如何将其转换为OID并从字段中获取值？

如果我只有字符串名称OID，我怎么能得到数字OID？

public class CustomX509TrustManager implements X509TrustManager{
private X509Certificate[] serverX509CertificateArray;
    @Override
    public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    @Override
    public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
            //TODO xcs array include: OID,...
        this.serverX509CertificateArray = xcs;
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return this.serverX509CertificateArray;
    }
}

代码部分：

SSLContext sslContext = SSLContext.getInstance("SSLv3");
sslContext.init(null, new TrustManager[] {new CustomX509TrustManager()}, new java.security.SecureRandom());
SSLSocketFactory ssf = sslContext.getSocketFactory();
HttpsURLConnection conn = (HttpsURLConnection) new URL("https://www.facebook.com/").openConnection();

        conn.setSSLSocketFactory(ssf);
        conn.setHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String string, SSLSession ssls) {
                return true;
            }
        });
        conn.setConnectTimeout(1000);
        conn.setReadTimeout(1000 * 2);
        conn.connect();
        //READ HTML
        conn.disconnect();
