vue引用高德地图实现选择定位，根据经纬度标注功能
引用vue-amap
yarn add vue-amap
main配置
// 引入vue-amap
import VueAMap from 'vue-amap';
Vue.use(VueAMap);
// 初始化vue-amap，高德的key值需要自己去申请
VueAMap.initAMapApiLoader({
key: '',
plugin: ['AMap.Scale', 'AMap.OverView', 'AMap.ToolBar', 'AMap.MapType', 'AMap.PlaceSearch', 'AMap.Geolocation', 'AMap.Geocoder'],
v: '1.4.4',
uiVersion: '1.0'
});
