I'm trying to read date from JSON using a URL , but it throws an exception. and the response from header is 301 Moved Permanently

this basically means the there is something wrong with link, but I cannot figure out what it is exactly since the API provider did not mention anything in regard to changes to their API

Any help is appreciated.

here is my code

private static String readUrl(String urlString) throws Exception {
        BufferedReader reader = null;
        try {
            URL url = new URL(urlString);
            reader = new BufferedReader(new InputStreamReader(url.openStream()));
            StringBuffer buffer = new StringBuffer();
            int read;
            char[] chars = new char[1024];
            while ((read = reader.read(chars)) != -1)
                buffer.append(chars, 0, read);

            return buffer.toString();
        } finally {
            if (reader != null)
                reader.close();
        }
    }

String url = "http://webservice.fanart.tv/v3/movies/" + movie.id + "?api_key=" + apikey;
        List<String> enClearLogos = new ArrayList<>();
        try {
            JSONObject json = new JSONObject(readUrl(url));
            JSONArray jsonArray = json.getJSONArray("hdmovielogo");
            for(int i = 0; i < jsonArray.length(); i++){
                JSONObject movieObject = jsonArray.getJSONObject(i);
                if (movieObject.getString("lang").equalsIgnoreCase("en"))
                    enClearLogos.add(movieObject.getString("url"));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

  • Please include the full exception message and stack trace in the question text – Tim Moore Oct 29 '22 at 23:18
  • Obviously, JSON you're trying to parse is invalid. Try to print it on the console. – Alexander Ivanchenko Oct 29 '22 at 23:34
  • it is the exact same thing on the console. I just did `curl 'https://webservice.fanart.tv/v3/movies/629542?api_key=xxxxxxxxxxxxxxx` – Steve Oct 29 '22 at 23:36
  • yes just like that , so what should it look like normally? – Steve Oct 29 '22 at 23:43

    Sorry, my bad, the sample-JSON is valid, it should be parsed fine (I've tried it). But exception should have a reason, either something is missing or something gets added to it. – Alexander Ivanchenko Oct 29 '22 at 23:52
  • you are right , I appreciate it , I did a little digging , I think it has sth to do with some sort of protection https://stackoverflow.com/questions/31912000/byethost-server-passing-html-values-checking-your-browser-with-json-string – Steve Oct 29 '22 at 23:56

The http:// causes url redirection and throws this message in the header response (301 Moved Permanently) so I had to use https:// instead now everything works nicely.
