सर्वर से JSON डाउनलोड करने का तरीका कैसे?

Question

क्या कोई अच्छा उदाहरण है कि सर्वर से पूछताछ और प्रतिक्रिया (जेएसओएन या एक्सएमएल) डाउनलोड करने का तरीका दिखा रहा है?

Answer 1

इस चाल करना चाहिए

String JsonResponse = HttpHelper.connect(SERVER_URL); 
JSONObject json=new JSONObject(JsonResponse); 

private static String convertStreamToString(InputStream is) { 
     /* 
     * To convert the InputStream to String we use the BufferedReader.readLine() 
     * method. We iterate until the BufferedReader return null which means 
     * there's no more data to read. Each line will appended to a StringBuilder 
     * and returned as String. 
     */ 
     BufferedReader reader = new BufferedReader(new InputStreamReader(is)); 
     StringBuilder sb = new StringBuilder(); 

     String line = null; 
     try { 
      while ((line = reader.readLine()) != null) { 
       sb.append(line + "\n"); 
      } 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 
      try { 
       is.close(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
     return sb.toString(); 
    } 
    public static String connect(String url) 
    { 
     HttpClient httpclient = new DefaultHttpClient(); 
     HttpGet httpget = new HttpGet(url); 
     HttpResponse response; 
     try { 
      response = httpclient.execute(httpget); 
      //Log.i(TAG,response.getStatusLine().toString()); 
      HttpEntity entity = response.getEntity(); 
      if (entity != null) { 
       InputStream instream = entity.getContent(); 
       String result= convertStreamToString(instream); 
       instream.close(); 
       return result; 
      } 
     } catch (ClientProtocolException e) { 
     } catch (IOException e) { 
     } 
     return null; 
    }
