JSON Question

Get a JSON object from a HTTP response

I want to get a

JSON
object from a Http get response:

Here is my current code for the Http get:

protected String doInBackground(String... params) {

HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(params[0]);
HttpResponse response;
String result = null;
try {
response = client.execute(request);
HttpEntity entity = response.getEntity();

if (entity != null) {

// A Simple JSON Response Read
InputStream instream = entity.getContent();
result = convertStreamToString(instream);
// now you have the string representation of the HTML request
System.out.println("RESPONSE: " + result);
instream.close();
if (response.getStatusLine().getStatusCode() == 200) {
netState.setLogginDone(true);
}

}
// Headers
org.apache.http.Header[] headers = response.getAllHeaders();
for (int i = 0; i < headers.length; i++) {
System.out.println(headers[i]);
}
} catch (ClientProtocolException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
return result;
}


Here is the convertSteamToString function:

private static String convertStreamToString(InputStream is) {

BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();

String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}


Right now I am just getting a string object. How can I get a JSON object back.

Answer

The string that you get is just the JSON Object.toString(). It means that you get the JSON object, but in a String format.

If you are supposed to get a JSON Object you can just put:

JSONObject myObject = new JSONObject(result);
