Adding JWT Token in Volley Request

Question

I am using Node.js at the Backend, and need to send some params(parameters) and a jwt token(for authorization) in header of a GET request. I am using express-jwt module at the node server. The request need to be authorized using jwt token there. Simply sending the token as params do not work there.

    private void getInfo(final String instanceId, final String token) {
//token is jwt token
            StringRequest strReq = new StringRequest(Request.Method.GET,
                    Config.URL_GET_ID_INFO, new Response.Listener<String>() {

                @Override
                public void onResponse(String response) {
                    Log.d(TAG, response);

                    try {
                        JSONObject responseObj = new JSONObject(response);
                        boolean error = responseObj.getBoolean("error");
                        String message = responseObj.getString("message");
                        if (!error) {

                            Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();

                        } else {
                            Toast.makeText(getApplicationContext(),
                                    "Error: " + message,
                                    Toast.LENGTH_LONG).show();
                        }

                        // hiding the progress bar
                        //progressBar.setVisibility(View.GONE);

                    } catch (JSONException e) {
                        Toast.makeText(getApplicationContext(),
                                "Error: " + e.getMessage(),
                                Toast.LENGTH_LONG).show();

                       // progressBar.setVisibility(View.GONE);
                    }

                }
            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.e(TAG, "Error: " + error.getMessage());
                    Toast.makeText(getApplicationContext(),
                            error.getMessage(), Toast.LENGTH_SHORT).show();
                    //progressBar.setVisibility(View.GONE);
                }
            }) {
                @Override
                protected Map<String, String> getParams() {
                    Map<String, String> params = new HashMap<String , String>();
                    params.put("instanceId", instanceId);

                    //Need to send jwt along with params, but do not know how to include it in the request.
                    Log.e(TAG, "Posting params: " + params.toString());

                    return params;
                }



            };

            // Adding request to request queue
            MyApplication.getInstance().addToRequestQueue(strReq);
        }

Just override the Request's method getHeaders()

Here's an example :

@Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String> params = new HashMap<String, String>();
            params.put("Authorization", "Bearer "+ yourToken);
            return params;
        }
