How to add JSON points from Web Service on JS API

[MattWilliams4]

I am looking to see if anyone can help me with some details and an example on how to add a points to a JS API 4.6 map when retrieved from a JSON web service.

I know I need to use the request function but an lost as to then how to put the points on the map AFTER I have retrieved the JSON data from the web service.

I have studied the esri samples like Flickr, etc but cant seem to get anything to work.

Any help is appreciated.

Thanks

That's the method I use to add a geoJSON do my map, You need to put the requires and adjust to your application.

        function loadJson(content, title) {
            var obj = eval('(' + content + ');');

            var gl = new GraphicsLayer({
                title: title
            });

            if (obj.features) {
                var symbol;
                switch (obj.geometryType) {
                    case "esriGeometryPolyline":
                        symbol = simboloAdicionaCamadaLinha.clone();
                        break;
                    case "esriGeometryPoint":
                        symbol = simboloAdicionaCamadaPonto.clone();
                        break;
                    case "esriGeometryPolygon":
                        var symbol = simboloAdicionaCamadaPoligono.clone();
                        break;

                };
                if (obj.spatialReference.wkid != 4326) {
                    copagisAlert.info('Sistema de coordenadas da camada a adicionar na web deve ser o GCS_WGS_1984 WKID: 4326');
                    return false;
                }

                for (var i = 0; i < obj.features.length; i++) {
                    var graphic = new Graphic({
                        geometry: geometryJsonUtils.fromJSON(obj.features[i].geometry),
                        symbol: symbol,
                        attributes: obj.features[i].attributes
                    });
                    gl.add(graphic);

                }
                gl.then(function () {
                    view.goTo(gl.graphics);
                });
                map.add(gl);
            }
        }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
