no post using ion library

Question

I am trying to post a json object through android ion library on a computer in my local network with the following code :

String url = "http://192.168.1.23/ws/svn/branches/application/public/connectMobile";
                    try {


                        JsonObject json = new JsonObject();
                        json.addProperty("email", email.getText().toString());
                        json.addProperty("psw", password.getText().toString());
                        Log.i("json envoyé",json.toString());



                            Ion.with(context)
                                    .load("POST",url)
                                    .addHeader("Content-Type", "application/json")
                                    .setLogging("ion-geny", Log.DEBUG)
                                    .setJsonObjectBody(json)
                                    .asJsonObject()
                                    .setCallback(new FutureCallback<JsonObject>() {
                                        @Override
                                        public void onCompleted(Exception e, JsonObject result) {
                                            if (result != null)
                                            {
                                                Log.i("result",result.toString());
                                            }
                                            else
                                            {
                                                Log.i("result","null");
                                            }
                                            if (e != null)
                                            {
                                                Log.i("error",e.toString());

                                            }
                                            else
                                            {
                                                Log.i("error","null");
                                            }

                                        }

                                    });



                    } catch (Exception ex) {
                        ex.printStackTrace();
                        Log.i("except", ex.toString());
                    }

The debug gives this :

I suspect that the parse error is due to the fact that nothing is returned.

Moreover, on my server, I wrote a piece of code to check what's coming in, and I receive nothing on the server from my sample but when trying with RESTEASY with firefox sending the same, the post is correctly sent my server receives the post and a response is sent back.

Any idea ? I can't figure out what's wrong...

Answer 1

if you are getting stuck regarding json parsing error because when you get result into JsonObject formate and try to get string usually people write wrong parsing so I write it in String formate now you need not to parse it you can get your response in String so you can get String easily using .toString and there are lot of mechanism to do this problem and lot of way to write code but meaning would be same but sometime you write code same and meaning also same but compiler could not translate it. so we get error that's why I write here string now you can get your response.

  .addHeader("Content-Type", "application/json")
                                .setLogging("ion-geny", Log.DEBUG)
                                .setJsonObjectBody(jsobj.getAsJsonObject())
                            .asString()
                                .setCallback(new FutureCallback<String>() {
                                    @Override
                                    public void onCompleted(Exception e, String result) {
                                        if (result != null)
                                        {
                                            Log.i("result",result.toString());
