ol3之加载geojson数据

数据：

let data  = {
  "type": "Feature",
  "geometry": {
    "type": "Point",
    "coordinates": [125.6, 10.1]
  },
  "properties": {
    "name": "Dinagat Islands"
  }
}

加载图层：

var vectorSource = new ol.source.Vector({
        features: (new ol.format.GeoJSON()).readFeatures(data)
      });
var vectorLayer = new ol.layer.Vector({
        source: vectorSource,
        style: ''
      });
this.map.addLayer(vectorLayer)

定位：

let extent = vectorSource.getExtent()
this.view.fit(extent)
