Problems with a webservice and population in Json

[rdvg...@gmail.com]

Hi,

I am trying to consume a webservice using the restful API. It correctly returns the information I request:

data => [{usuarioid=17, usuario=demo1, nombreempresa=Embutidora Nacional, impuesto=7, menuid=1, dispositivoid=4, leehuella=1, imei=55555, correo=rube...@yahoo.com, nombre=Usuario Embutidos, radio=300, fuenteinventario=A, permitecambiarfoto=1, iniciosesion=1, contrasena=202cb962ac59075b964b07152d234b70, rangoinicio=100001, rangofin=150000, secuenciaorden=100054, estado=A, token=0a5b3d4a-5b8f-443d-af8e-cfb4100b71c4}]

To consume I do the following:

public static void login(Idioma idioma, String usuario, String contrasena, final SuccessCallback<Usuario> onSuccess, final FailureCallback<Object> onError) {  

        Rest.get(SERVER_URL + "blank_ws_autenticar/blank_ws_autenticar.php").

                acceptJson().

                queryParam("contrasena", contrasena).

                queryParam("usuario", usuario).

                getAsJsonMapAsync(new Callback<Response<Map>>() {

                    @Override

                    public void onSucess(Response<Map> value) {

                        usr = new Usuario();

                        PreferencesObject.create(usr).bind(); 

                        usr.getPropertyIndex().populateFromMap(value.getResponseData());

                        onSuccess.onSucess(usr);

                    }

                    @Override

                    public void onError(Object sender, Throwable err, int errorCode, String errorMessage) {

                        onError.onError(null, err, errorCode, errorMessage);

                    }

                });

    }

I cannot pass the information through the property "populateFromMap"

What is the correct way to do it?

Thanks

Hi,

It's hard to tell. Is the printout of data related to value.getResponseData()?

What are the fields of User?

How does it fail? Is the user object not set?
If you step over it with a debugger is it set for a short while?

Hi,

In debug the value value.getResponseData () is:

I have "usuario" class that implements PropertyBusinessObject to receive interaction "0" (see image).

When I try to receive the fields from the class they are in null (  usr.getPropertyIndex().populateFromMap(value.getResponseData());  ).

Thanks

Hi,

It's a bit hard to read in this way but it looks like the server returns a list of users.

So you would need something like this:

Map responseMap = value.getResponseData();

List entries = (List)responseMap.get("data");

usr.getPropertyIndex().populateFromMap((Map)entries.get(0));

Hi,

Return error in List entries = (List)responseMap.get("data");

Hi,

In with a JSON validator on the internet I put the URL that I am using:

http://3.12.118.139:8091/scriptcase/app/tempus/blank_ws_autenticar/blank_ws_autenticar.php?usuario=demo1&contrasena=123

I was able to verify that the ws is working well as the validation resulted in:

[ { "usuario_id":"17", "usuario":"demo1", "nombre_empresa":"Embutidora Nacional", "impuesto":"7", "menu_id":"1", "dispositivo_id":"4", "lee_huella":"1", "imei":"55555", "numero_telefono":"64237770", "correo":"rube...@yahoo.com", "nombre":"Usuario Embutidos", "radio":"300", "fuente_inventario":"A", "permite_cambiar_foto":"1", "inicio_sesion":"1", "rango_inicio":"100001", "rango_fin":"150000", "secuencia_orden":"100054", "estado":"A", "token":"0a5b3d4a-5b8f-443d-af8e-cfb4100b71c4" }]

For some reason that I do not understand, I am resiving it as a list and therefore my problem must be with the client. The method to receive is:

 

public static void login(Idioma idioma, String usuario, String contrasena, final SuccessCallback<Usuario> onSuccess, final FailureCallback<Object> onError) {

          Rest.get(SERVER_URL + "blank_ws_autenticar/blank_ws_autenticar.php").

                acceptJson().

                queryParam("contrasena", contrasena).

                queryParam("usuario", usuario).

                getAsJsonMapAsync(new Callback<Response<Map>>() {

                    @Override

                    public void onSucess(Response<Map> value) {

                        usr = new Usuario();

                        PreferencesObject.create(usr).bind();

                        usr.getPropertyIndex().populateFromMap(value.getResponseData());

                        onSuccess.onSucess(usr);

                    }

                    @Override

                    public void onError(Object sender, Throwable err, int errorCode, String errorMessage) {

                        onError.onError(null, err, errorCode, errorMessage);

                    }

                });

      }

I appreciate you pointing out what I'm doing wrong.

Thanks

In JSON [] means array or list and {} means object or map. So you do have a list of maps in the jSON which is what you see in Java.

Sorry it wasn't clear but I means java.util.List not com.codename1.ui.List. If you fix your import the code I posted above should work.

Hi,

Thank you very much, it works well.
