1. 效果图

2. 画线

2.1 html

<baidu-map class="bm-view" :scroll-wheel-zoom="true" :center="map.center" :zoom="map.zoom">
      <bm-polyline :path="lineList" stroke-color="red" :stroke-opacity="0.5" :stroke-weight="2"></bm-polyline>
</baidu-map>

2.2 data

lineList: []
// 返回格式:
// lineList: [
//   { lng: 116.404, lat: 39.915 },
//   { lng: 116.375, lat: 39.824 },
//   { lng: 116.423, lat: 39.9 }
// ]

后端返回数据

2.3 js 格式化后端返回数据

async getList() {
   let code = ".1.";
   this.lineList = [];
   let jsonArr = [];
   let res = await axiosRest(Settings.MapCoords + code, {}, "get");
   if (res.data.features[0].geometry.type == "Polygon") {
     jsonArr = res.data.features[0].geometry.coordinates;
   }
   for (let i = 0; i < jsonArr[0].length; i++) {
     let obj = {};
     obj.lng = jsonArr[0][i][0];
     obj.lat = jsonArr[0][i][1];
     this.lineList.push(obj);
   }
   console.log(this.lineList);
 },

格式化后 this.lineList 数据
