I am using Ion library to send JsonArray to the web service and get JSOn output. The same url and and input are working well on postman giving the correct result. But when supplied the same url and input through Ion library, it is giving the Request error in xml format.
Please help me to get rid of this, following the code i am using
Ion.with(PracticalExam.this)
.load(url)
.setJsonArrayBody(jsonArray)
.asString()
.setCallback(new FutureCallback<String>() {
@Override
public void onCompleted(Exception e, String result)
{
String error=null;
System.out.println("RESPONSE===> "+result);
}
});
Below is the response I get

I tried following as per the suggestions but still getting null result
Ion.with(PracticalExam.this)
.load("POST",url)
.addQuery("action", "dummyAction")
.addHeader("Content-Type", "application/json")
.setJsonArrayBody(jsonArray)
.asJsonObject()
.setCallback(new FutureCallback<JsonObject>()
{
@Override
public void onCompleted(Exception e, JsonObject result)
{
pd.dismiss();
System.out.println("Result=> " + result);
System.out.println("Exception=> "+e);
}
});
Ion did not work for me, hence i did it using AsyncTask, Below is the code
public class SendJsonArrayToServer extends AsyncTask<String, String, String>
{
String jsonData;
private String JsonResponse;
HttpURLConnection urlConnection = null;
BufferedReader reader = null;
@Override
protected void onPreExecute() {
super.onPreExecute();
pd.setMessage("Saving...");
pd.show();
}
@Override
protected String doInBackground(String... params)
{
String jsonResponse = null;
String jsonData = params[0];
try
{
URL url = new URL("http://xxxxxxxxxxxxx/xxxxxxxxxxxxx");
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setRequestMethod("POST");
Writer writer = new BufferedWriter(new OutputStreamWriter(urlConnection.getOutputStream(), "UTF-8"));
writer.write(jsonData);
writer.close();
InputStream inputStream = urlConnection.getInputStream();
StringBuffer buffer = new StringBuffer();
if (inputStream == null) {
// Nothing to do.
return null;
}
reader = new BufferedReader(new InputStreamReader(inputStream));
String inputLine;
while ((inputLine = reader.readLine()) != null)
buffer.append(inputLine + "\n");
if (buffer.length() == 0)
{
// Stream was empty. No point in parsing.
return null;
}
JsonResponse = buffer.toString();
//send to post execute
return JsonResponse;
}catch (Exception e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String s)
{
super.onPostExecute(s);
try {
urlConnection.disconnect();
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
pd.dismiss();
}
and call AsyncTask using
new SendJsonArrayToServer().execute(String.valueOf(jsonArray));
