Send POST request of Json Array as data to server using volley

Question

I want to send a post request using volley. I have data in this format.

  [{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"10:29:17","id":1},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"15:59:41","id":2},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"16:05:53","id":3},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"16:06:16","id":4},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"16:06:51","id":5},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"16:08:36","id":6},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"16:13:33","id":7},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"16:22:32","id":8},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"17:00:46","id":9},{"date":"24 Jul 2015","doctorEmail":"[email protected]","doctorName":"aquib","time":"17:04:04","id":10}]

And I am getting response in this format

{"Message" : "Success"}

I have written this code to send request.

   public void saveDataToServer(String data){

        final String BASE_URL = "http://spirantcommunication.com/andriod/grl/doctor_visit_track1.php";
        final String DOCTOR_JSON_PARAM = "doctorJson";

        HashMap<String, String> params = new HashMap<>();
        params.put(DOCTOR_JSON_PARAM, data);

        JsonObjectRequest request = new JsonObjectRequest(BASE_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) {

            }
        });

        MySingleton.getInstance(this).addToRequestQueue(request);
    }

But I am not able to send it.Please somebody help me.

In order to send some post parameters using volley you have to override getParams() method which should return list of parameters to be send in a key value format.

Kindly follow below code segment for sending proper post parameters to server.

// Tag used to cancel the request
String tag_json_obj = "json_obj_req";

                  JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
                url, null,
                new Response.Listener<JSONObject>() {

                    @Override
                    public void onResponse(JSONObject response) {
                        Log.d(TAG, response.toString());
                                                }
                }, new Response.ErrorListener() {

                    @Override
                    public void onErrorResponse(VolleyError error) {
                        VolleyLog.d(TAG, "Error: " + error.getMessage());
                                               }
                }) {

            @Override
            protected Map<String, String> getParams() {
                Map<String, String> params = new HashMap<String, String>();
                params.put(DOCTOR_JSON_PARAM, data);                 

                return params;
            }

        };

// Adding request to request queue
 MySingleton.getInstance(this).addToRequestQueue(jsonObjReq, tag_json_obj);
