Send POST request with JSON data using Volley

Question

I would like to send a new JsonObjectRequest request:

• I want to receive JSON data (response from server): OK

• I want to send JSON form

Answer 1

final String URL = "/volley/resource/12";
// Post params to be sent to the server
HashMap<String, String> params = new HashMap<String, String>();
params.put("token", "AbCdEfGh123456");

JsonObjectRequest req = new JsonObjectRequest(URL, new JSONObject(params),
       new Response.Listener<JSONObject>() {
           @Override
           public void onResponse(JSONObject response) {
               try {
                   VolleyLog.v("Response:%n %s", response.toString(4));
               } catch (JSONException e) {
                   e.printStackTrace();
               }
           }
       }, new Response.ErrorListener() {
           @Override
           public void onErrorResponse(VolleyError error) {
               VolleyLog.e("Error: ", error.getMessage());
           }
       });

// add the request object to the queue to be executed
ApplicationController.getInstance().addToRequestQueue(req);

Answer 2

final Map<String,String> params = new HashMap<String,String>();
        params.put("email", customer.getEmail());
        params.put("password", customer.getPassword());
        String url = Constants.BASE_URL+"login";

doWebRequestPost(url, params);


public void doWebRequestPost(String url, final Map<String,String> json){
        getmDialogListener().showDialog();

    StringRequest post = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            try {
                getmDialogListener().dismissDialog();
                response....

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.d(App.TAG,error.toString());
            getmDialogListener().dismissDialog();

        }
    }){
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Map<String,String> map = json;

            return map;
        }
    };
    App.getInstance().getRequestQueue().add(post);

}
