Convert InputStream to JSONObject

Question

I am converting InputStream to JSONObject using following code. My question is, is there any simple way to convert InputStream to JSONObject. Without doing InputStream -> Bu

Answer 1

This code works

BufferedReader bR = new BufferedReader(  new InputStreamReader(inputStream));
String line = "";

StringBuilder responseStrBuilder = new StringBuilder();
while((line =  bR.readLine()) != null){

    responseStrBuilder.append(line);
}
inputStream.close();

JSONObject result= new JSONObject(responseStrBuilder.toString());       

Answer 2

Here is a solution that doesn't use a loop and uses the Android API only:

InputStream inputStreamObject = PositionKeeperRequestTest.class.getResourceAsStream(jsonFileName);
byte[] data = new byte[inputStreamObject.available()];
if(inputStreamObject.read(data) == data.length) {
    JSONObject jsonObject = new JSONObject(new String(data));
}

Answer 3

The best solution in my opinion is to encapsulate the InputStream in a JSONTokener object. Something like this:

JSONObject jsonObject = new JSONObject(new JSONTokener(inputStream));

Answer 4

Simple Solution:

JsonElement element = new JsonParser().parse(new InputStreamReader(inputStream));
JSONObject jsonObject = new JSONObject(element.getAsJsonObject().toString());

Answer 5

Make use of Jackson JSON Parser

ObjectMapper mapper = new ObjectMapper();
Map<String,Object> map = mapper.readValue(inputStreamObject,Map.class);

If you want specifically a JSONObject then you can convert the map

JSONObject json = new JSONObject(map);

Refer this for the usage of JSONObject constructor http://stleary.github.io/JSON-java/index.html

Answer 6

This worked for me:

JSONArray jsonarr = (JSONArray) new JSONParser().parse(new InputStreamReader(Nameofclass.class.getResourceAsStream(pathToJSONFile)));
JSONObject jsonobj = (JSONObject) new JSONParser().parse(new InputStreamReader(Nameofclass.class.getResourceAsStream(pathToJSONFile)));
