Put ArrayList into param JsonObject

Question

i must do i request with Volley Framework. This is a POST request with JSONObject.

I must pass one string and one JSONArray..but how i can?

I start with this:

Click to copy

 private String mUrl;
    private ArrayList<String> mUrlDove;

  HashMap<String, String> params = new HashMap<String, String>();
            params.put("url", mUrl);
            params.put("urlDove", mUrlDove); ---> Wrong because mUrlDove is not a String


            mUrl = app.getInstance().getmUrlRestWS() + getString(R.string.path);

            JsonObjectRequest mRequest = new JsonObjectRequest(
                    mUrl, new JSONObject(params),
                    createMyReqSuccessListener(),
                    createMyReqErrorListener()) {
                @Override
                public Map<String, String> getHeaders() throws AuthFailureError {
                    return app.getInstance().createBasicAuthHeader();
                }
            };

If i try with Browser i must set this:

Click to copy

{
  "url": "www.secret.com",
  "urlDove" : [ "www.google.com","www.yahoo.com"]
}

Answer 1

try passing JSONObject instead of hashmap

Click to copy

JSONObject params = new JSONObject();
params.put("url", "www.secret.com");

JSONArray urlDove = new JSONArray();
urlDove.put("www.google.com");
urlDove.put("www.yahoo.com");

params.put("urlDove", urlDove);


JsonObjectRequest mRequest = new JsonObjectRequest(
                mUrl, params,
                createMyReqSuccessListener(),
                createMyReqErrorListener()) {
            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                return app.getInstance().createBasicAuthHeader();
            }
        };

you need to make a JSON Array first and then store that

Click to copy

private String mUrl;
private ArrayList<String> mUrlDove;

HashMap<String, String> params = new HashMap<String, String>();
        params.put("url", mUrl);
        JSONArray jsArray = new JSONArray(mUrlDove);
        params.put("urlDove", jsArray.toString()); 

        mUrl = app.getInstance().getmUrlRestWS() + getString(R.string.path);

        JsonObjectRequest mRequest = new JsonObjectRequest(
                mUrl, new JSONObject(params),
                createMyReqSuccessListener(),
                createMyReqErrorListener()) {
            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                return app.getInstance().createBasicAuthHeader();
            }
        };
