我有一份geojson数据：const smc={"type":"FeatureCollection", "features": [svg转geojson，{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[119.66253898412081,30.

直接上代码：var vector = new ol.layer.Vector({source: new ol.source.Vector({url: './data/geojson/countries.geojson',format: new ol.format.GeoJSON()})});　　 map.addLayer(vector); 转载于:https://www.cnblogs.com/marost/p/7352531.html
