[Android] JSON parsing Error - "JSONException e"

JSON parsing을 공부하는 중.

json exception이 발생했다.

처음으로 run 시켰던 때라 이게 뭣때문인지 몰랐다.

public static JSONObject jObject; private static String SCREEN_NAME = "screen_name"; private static String DESCRIPTION = "description"; private static String URL = "url"; public static void twitParse() { try { URL url = new URL("http://api.twitter.com/1/users/show.json?screen_name=croute17"); URLConnection urlConnection = url.openConnection(); HttpURLConnection httpUrlConnection = (HttpURLConnection)urlConnection; int responseCode = httpUrlConnection.getResponseCode(); if (responseCode == HttpURLConnection.HTTP_OK) { InputStream inputStream = httpUrlConnection.getInputStream(); String str = inputStream.toString(); Log.i("str", str); jObject = new JSONObject(str); String screen_name = jObject.getString(SCREEN_NAME); Log.i(SCREEN_NAME, screen_name); String description = jObject.getString(DESCRIPTION); Log.i(DESCRIPTION, description); String url_link = jObject.getString(URL); Log.i(URL, url_link); } } catch (MalformedURLException e) { Log.e("error", "url fault"); e.printStackTrace(); } catch (IOException e) { Log.e("error", "I/O exception"); e.printStackTrace(); } catch (JSONException e) { Log.e("error", "json exception"); e.printStackTrace(); } }

대충 짐작해 봤을 때, InputStream type으로 되있는걸 단순하게 .toString() 으로 String type으로 컨버팅한게 문제였던 것 같다.

그래서 아래처럼 코드를 수정해 주었다.

결과는 양호!!

String str = inputStream.toString();

----->>>>> String str = convertStreamToString(inputStream);

converStreamToString() 메소드

public static String convertStreamToString(InputStream inputStream) { if (inputStream != null) { Writer writer = new StringWriter(); char[] buffer = new char[1024]; try { Reader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8")); int n; while ((n=reader.read(buffer))!=-1) { writer.write(buffer, 0, n); } return writer.toString(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } return null; }
