该组件配置了高德和腾讯地图的底图。具有新建图层和打点（使用leaflet中的方法），打点分为单个和多个。经纬度和详细地址的互相转换由高德api完成。

使用leaflet新建一底图的简写方式

let map = L.map('map').setView([39.90887, 116.397435], 17);

复杂icon标点

// latlngs是标点坐标，格式同初始化地图时的中心坐标
let marker = L.marker(latlngs, {icon: L.divIcon({className: "dIcon", //标点icon的容器类名html:`标点icon的html字段内容`, //可以添加标点名字之类的自定义内容// iconSize: [60, 24] //标点icon的容器大小，也可以直接用className类名写css样式})
}).addTo(map); //添加到地图中
