Getting an error when parsing a JSONObject

Question

I'm trying to get a data from an online JSON, so getting the json and printing it works without issue, but when I want a particular data, my IDE give me this error

org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]

I tried many solutions but none works for me, or I'm still too novice to adapt solution to my code, it will be very nice if someone can help me with this. I'm stuck on it since a long moment now.

So here is my code:

public class Main {

    public static void main(String[] args) throws Exception {
        File file = new File("src/main/java/ressources/config.txt");
        List<String> list = Files.readAllLines(file.toPath(), StandardCharsets.UTF_8);
        String url = "https://osu.ppy.sh/api/get_user?k=" + list.get(1) + "&u=" + list.get(0);

        System.out.println(url);
        System.out.println(readUrl(url));

        try {
            JSONObject json = new JSONObject(readUrl(url));

            String mydata = (String) json.get("ranked_score");
            System.out.println(mydata);

        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

    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();
        }
    }
}

And the JSON give me this

Answer 1

You are getting an array at the top level instead of a JSON object. You should use JSONArray instead of JSONObject to parse the inital response object.

JSONObject json = new JSONObject(readUrl(url));

to

JSONArray json = new JSONArray(readUrl(url));

Then you need to grab an object out of the array

JSONObject object = json.getJSONObject(0);
object.getString("ranked_score");

The fact that you are getting an Array response likely means there is or can be more than one object in the response. You may only have to deal with the first object in the array but it depends on what exactly the endpoint is returning.

Answer 2

Use this instead of your previous line:

String content=readUrl(url);
JSONObject json = new JSONObject(content.substring(1,content.length()-1);

This will remove the [ and ] from outside so it will become a valid JSON object without breaking anything.
