java.security.cert.CertificateException：沒有主題替代 DNS 名稱匹配

Question

我正在通過 REST api 編寫文件閱讀器，簡單代碼如下：

import domain

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.ssl.HttpsURLConnection;
import java.net.MalformedURLException;

public class Verifier{
    public static void main(String args[]) throws IOException
    {
        URL url = new URL("https://somehostname.xx.xxx.net/somecontent?somequery=number");
        try{
            HttpsURLConnection http=(HttpsURLConnection) url.openConnection();
            int reponse = http.getResponseCode();
            //some json processing
            //...
           }catch (MalformedURLException e) {
               e.printStackTrace();
           }catch (IOException e) {
               e.printStackTrace();
           }
    }
}

然后我在行中得到了錯誤

int reponse = http.getResponseCode();

錯誤消息是：

同一個站點的內容可以通過chrome瀏覽器檢索到，不需要任何用戶名和密碼（但是在IE瀏覽器中確實顯示了這個網站的安全證書有問題，在Chrome中沒有，你可以繼續獲取json內容而無需輸入任何內容）。

我在想 JAVA/eclipse 中可能存在一些證書問題，也許吧？ 我該如何解決？

謝謝。

SSLContext sc = SSLContext.getInstance( "TLS");
        TrustManager[] tmArr = {new X509TrustManager() {
            @Override
            public void checkClientTrusted(
                    X509Certificate[] paramArrayOfX509Certificate,
                    String paramString) throws CertificateException {
            }

            @Override
            public void checkServerTrusted(
                    X509Certificate[] paramArrayOfX509Certificate,
                    String paramString) throws CertificateException {
            }

            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        }};
        sc.init(null, tmArr, new SecureRandom());
        if (isDetail) {
            if (!ValueWidget.isNullOrEmpty(tmArr)) {
                System.out.println("first TrustManager:" + tmArr[0]);
            }
        }
        huc = (HttpsURLConnection) url.openConnection();

            //解決 javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative DNS name matching apis.map.qq.com found.
            ((HttpsURLConnection) huc).setHostnameVerifier(new HostnameVerifier() {
                @Override
                public boolean verify(String s, SSLSession sslSession) {
                    return true;
                }
            });
