openlayers wfs层不出现

Question

在openlayers 4.4中，我有一个图层，其来源来自mapserver。 通过执行AdministrationSource.getFeatures（）。 ForEach（功能（功能）{     console.log（feature.getGeometry（）getCoordinates（）。）; 我有一个几何列表，但是它们没有出现在我的图层上。 我不知道它是否来自mapserver .map文件或openlayers。 openlayers代码

var administrationSource =  new ol.source.Vector({
    format: new ol.format.GeoJSON(),
    url: function (extent,resolution) { 
     if (resolution<2) {return 'http://10.210.1.32:8080/cgi-bin/mapserv.exe?map=C:/ms4w/map/fond_mapserver_wfs_ol4.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=administration2&OUTPUTFORMAT=geojson&SRSNAME=EPSG:2154&bbox='+ extent.join(',') + ',EPSG:3857';
      }},
    strategy: ol.loadingstrategy.bbox
    });
     var administrationwfs =  new ol.layer.Vector({
    source: administrationSource,
    maxResolution: 2 ,
    style: new ol.style.Style({
      stroke: new ol.style.Stroke({
        color: 'rgba(255, 51, 0, 1.0)',
        width: 2
      })
    })
  });
     map.addLayer(administrationwfs);
