注意：直接引入script的话，可能会报错：Bmap is not defined

解决方案：

第一步：新建一个map.js

export function MP(ak) {

    return new Promise(function (resolve, reject) {

        window.onload = function () {

            resolve(BMap)

        }

        var script = document.createElement("script");

        script.type = "text/javascript";

        script.src = "http://api.map.baidu.com/api?v=2.0&ak="+ak+"&callback=init";

        script.onerror = reject;

        document.head.appendChild(script);

    })

}

第二步：在你的百度地图页面中调用(ak 就是你的密钥)

import {MP} from './map.js'

mounted(){

    this.$nextTick(function(){

        var _this = this;

        MP(_this.ak).then(BMap => {

            //在此调用api

            _this.getMyLocation();

        }）

    })

}

第三步：调用百度api去获取地理信息

getMyLocation(){

    var that=this;

    var geolocation = new BMap.Geolocation();

    geolocation.getCurrentPosition((r) => {

        that.latitude = r.latitude;

        that.longitude = r.longitude;

        that.getActStoreAreaList();

    }, { enableHighAccuracy: true })

},
