Android Volley: Headers are not appended

Question

I am trying to implement tokenization in my Android app, and for that I always need to add the authorization header to my request anytime I make one to the server. The problem is that when I debug the server instance, even if the request is made, there is no Authorization header added in it that

Here is my code

private void syncDatabases()
{
    String tag_json_obj = "json_obj_req";
    String uri = "random_url";
    final ProgressDialog pDialog = new ProgressDialog(this);
    pDialog.setMessage("Please wait while syncing");
    pDialog.show();

    List<Plane> allPlane = service.gettAllPlane();
    Gson gson = new Gson();
    JSONArray jsArray = new JSONArray();

    for (Plane p : allPlane)
    {
        String jsonString = gson.toJson(p);
        try {
            JSONObject obj = new JSONObject(jsonString);
            obj.remove("ID");
            jsArray.put(obj);

        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

    JsonArrayRequest jsonObjReq = new JsonArrayRequest(Request.Method.POST, uri, jsArray, new Response.Listener<JSONArray>()
    {
        @Override
        public void onResponse(JSONArray response)
        {
            ArrayList<Plane> newList = new ArrayList<>();
            try
            {
                for(int i=0;i<response.length();i++)
                {
                    String planeName,planeEngine,planeProducer,planeCountry,planeYear,wikiLink,ID;
                    JSONObject pl = response.getJSONObject(i);

                    String p1 = pl.optString("ID");
                    if (pl != null && !p1.isEmpty())
                        ID = pl.getString("ID");
                    else
                        ID = "0";

                    String p2 = pl.optString("planeName");
                    if (p2 != null && !p2.isEmpty())
                        planeName = pl.getString("planeName");
                    else
                        planeName = "";

                    String p3 = pl.optString("planeEngine");
                    if (p3 != null && !p3.isEmpty())
                        planeEngine = pl.getString("planeEngine");
                    else
                        planeEngine = "";

                    String p4 = pl.optString("planeProducer");
                    if (p4 != null && !p4.isEmpty())
                        planeProducer = pl.getString("planeProducer");
                    else
                        planeProducer = "";

                    String p5 = pl.optString("planeCountry");
                    if (p5 != null && !p5.isEmpty())
                        planeCountry = pl.getString("planeCountry");
                    else
                        planeCountry = "";

                    String p6 = pl.optString("planeYear");
                    if (p6 != null && !p6.isEmpty())
                        planeYear = pl.getString("planeYear");
                    else
                        planeYear = "0";

                    String p7 = pl.optString("wikiLink");
                    if (p7 != null && !p7.isEmpty())
                        wikiLink = pl.getString("wikiLink");
                    else
                        wikiLink = "";

                    Plane plf = new Plane(Integer.parseInt(ID),planeName,planeEngine,planeProducer,planeCountry,Integer.parseInt(planeYear),wikiLink);
                    newList.add(plf);
                }
            }
            catch (JSONException e)
            {
                e.printStackTrace();
            }

            service.deleteAllFromPlane();
            for (Plane p : newList)
            {
                boolean ok = service.addNewPlane(p);
            }
            pDialog.dismiss();
            tab1.onIorU();

        }

    }, new Response.ErrorListener()
    {
        @Override
        public void onErrorResponse(VolleyError error)
        {
            Log.e("ERROR", "Error occurred ", error);
            pDialog.dismiss();
        }
    })
    {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError
        {
            SharedPreferences settings = PreferenceManager
                    .getDefaultSharedPreferences(MainActivity.this);
            String auth_token_string = settings.getString("token", "");

            Map<String, String> params = new HashMap<>();
            params.put("Content-Type", "application/json; charset=UTF-8");
            params.put("Authorization", auth_token_string);
            return params;
        }
    };

I already verified if auth_token_string is null (it isn't). Here is what I see on the server side (C# Web API 2 server)

And here is how I get the header:

var authorization = request.Headers.Authorization;

In the pic you can see a part of the token I try to send in the headers field though. What am I doing wrong? Thank you.

Answer 1

In your authorization token you are missing Type of authorization. I am asuming that you are using Bacis auth, so try using this:

params.put("Authorization", "Basic " + auth_token_string);
