내가 할 필요가 내 응용 프로그램 중 하나에있는 모든 안녕하세요 ... 내가이

public class UrlPinger extends AsyncTask<URL, Void, Void> { 

     @Override 
     protected Void doInBackground(URL... urls) { 
      URL url = urls[0]; 

      try { 
       HttpURLConnection urlConnection = (HttpURLConnection) url 
         .openConnection(); 
       urlConnection.connect(); 
       System.out.println("thisi si wie URL>>>"+url+""); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
       System.out.println("ERROR "+e.getMessage()+""); 
      } 

      return null; 

     } 

위의 클래스 나에게 오류를 포기하지 않을 수행 한 모든 URL을 명중 URL을 잘못 누르지 않았습니까? 이

UrlPinger pinger = new UrlPinger(); 
        pinger.execute(myURL);// this is perfect url copy pase in browser hits

Answer 1

HttpURLConnection connection = null; 
    try { 
     URL u = new URL("http://www.google.com/"); 
     connection = (HttpURLConnection) u.openConnection(); 
     connection.setRequestMethod("HEAD"); 
     int code = connection.getResponseCode(); 
     System.out.println("" + code); 
     // You can determine on HTTP return code received. 200 is success. 
    } catch (MalformedURLException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } finally { 
     if (connection != null) { 
      connection.disconnect(); 
     } 
    }
