Load a file geojson in OpenLayers 3

[المشرف العام]

Before, to load my .geojson, I had a php file who generated the code :

var vector_limite_comm_white = new ol.layer.Vector({ source: new ol.source.GeoJSON({ url: 'geojson1.php', defaultProjection :'EPSG:4326', projection: 'EPSG:3857' }), name: 'NAME 1', style: style_white()})After, I tried to directly load my geojson file, so I wrote :

var vector_name1 = new ol.layer.Vector({ source: new ol.source.Vector ({ url: 'data/json/file1.geojson', defaultProjection :'EPSG:4323', projection: 'EPSG:3857' }), name: 'NAME 1', style: style_white()})In firebug, at onload event, I saw my geojson file was loaded correctly but, it doesn't appear in my map. So I tried an other method like that :

var test = 'data/json/file1.geojson';var vectorSource = new ol.source.Vector({ features: (new ol.format.GeoJSON()).readFeature(test)}); var vector_overlay = new ol.layer.Vector({ source: vectorSource, style: new ol.style.Style(style_white()});It's not a good method too.

Do you have some explications?
