получение данных XML через https: //

Question

Мой код работает для http, но не для https.Вот сообщение об ошибке, которое я получаю, когда я вызываю getMessage () на IOException :

java.net.SocketException: семейство адресов не поддерживается протоколом

вот мой код:

 package com.evankimia;

 import java.io.IOException;
 import java.io.StringReader;
 import java.io.UnsupportedEncodingException;
 import java.net.MalformedURLException;

 import android.os.Bundle;
 import android.util.Log;

 public class XMLParserTestActivity extends Activity {
     /** Called when the activity is first created. */
     @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);       
    {
        Log.e("sys",""+getXML());

     }
 }

    public  String getXML(){
        String line = null;

        try {

            DefaultHttpClient httpClient = this.createHttpClient();
            HttpPost httpPost = new HttpPost("https://web2.uconn.edu/driver/old/timepoints.php?stopid=10");

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            line = EntityUtils.toString(httpEntity);

        } catch (UnsupportedEncodingException e) {
            line = "<results status=\"error\"><msg>Cans't connect to server</msg></results>";
        } catch (MalformedURLException e) {
            line = "<results status=\"error\"><msg>Cand't connect to server</msg></results>";
        } catch (IOException e) {
            line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
            e.getMessage();
        }

        return line;

}

private DefaultHttpClient createHttpClient()
{
    HttpParams params = new BasicHttpParams();
    HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
    HttpProtocolParams.setContentCharset(params, HTTP.DEFAULT_CONTENT_CHARSET);
    HttpProtocolParams.setUseExpectContinue(params, true);

    SchemeRegistry schReg = new SchemeRegistry();
    schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    schReg.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
    ClientConnectionManager conMgr = new ThreadSafeClientConnManager(params, schReg);

    return new DefaultHttpClient(conMgr, params);
}

 }

Метод, который вы перечислили, работает только для http.Сделайте так, чтобы ваша программа идентифицировала URL-адрес https и используйте некоторые теги, подобные следующим.

 /**
 * Initialize the HTTP/S connection (if needed)
 *
 * @param  keystoreFile  the full path of the keystore file
 * @param  keystorePass  the password for the keystore file
 */
private void initHttps(String keystoreFile, String keystorePass)
{
    // check if the URL uses HTTP/S
    if (url.toLowerCase().startsWith(HTTPS_PROTOCOL))
    {
        print("Initializing HTTP/S protocol...");
        // set the system properties needed for HTTP/S
        System.setProperty("javax.net.ssl.keyStore", keystoreFile);
        System.setProperty("javax.net.ssl.keyStorePassword", keystorePass);
        System.setProperty("javax.net.ssl.keyStoreType", "JKS");
        System.setProperty("javax.net.ssl.trustStore", keystoreFile);
        System.setProperty("javax.net.ssl.trustStorePassword", keystorePass);
        System.setProperty("javax.protocol.handler.pkgs",
            "com.sun.net.ssl.internal.www.protocol");
        //int addProvider = Security.addProvider(new       com.sun.net.ssl.internal.ssl.Provider());
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {   // fix a HTTP/S handshake issue
            public boolean verify(String hostName, SSLSession session)
            {   // Verify that the host name is acceptable 
                return true;
            }
        });
    }
}
