How to convert HttpEntity into JSON?

I want to retrieve JSON from a web-service and parse it then.
Am I on the right way?

    HttpClient httpclient = new DefaultHttpClient();
    HttpGet htt         


        

Answer 1

You can convert string to json as:

try {
        response = httpclient.execute(httpget);
        HttpEntity entity = response.getEntity();

        if (entity != null) {
           String retSrc = EntityUtils.toString(entity); 
           // parsing JSON
           JSONObject result = new JSONObject(retSrc); //Convert String to JSON Object

             JSONArray tokenList = result.getJSONArray("names");
             JSONObject oj = tokenList.getJSONObject(0);
             String token = oj.getString("name"); 
        }
}
 catch (Exception e) {
  }

Use the entity.getContent() to get the InputStream and convert it to String.

Answer 3

Try this

public String getMyFeed(){
    HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet(url);
    HttpResponse response = httpclien.execute(httpget);

    HttpEntity entity = response.getEntity();
    HttpInputStream content = entity.getContent();

    StatusLine sl = response.getStatusLine();
    int statCode = sl.getStatusCode()

   if (statCode ==200){

    // process it

}

}


String readFeed  = getMyFeed();
JSONArray jArr = new JSONArray(readFeed);

for(int i=0 ; i<jArr.length ; i++)
JSONObject jObj = jArr.getJSONObject(i);

Answer 4

Using gson and EntityUtils:

HttpEntity responseEntity = response.getEntity();

try {
    if (responseEntity != null) {
        String responseString = EntityUtils.toString(responseEntity);
        JsonObject jsonResp = new Gson().fromJson(responseString, JsonObject.class); // String to JSONObject

    if (jsonResp.has("property"))
        System.out.println(jsonResp.get("property").toString().replace("\"", ""))); // toString returns quoted values!

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