第一步，在public文件夹下的index.html中添加百度地图的script

<script type="text/javascript" src="https://api.map.baidu.com/getscript?v=3.0&ak=您的密钥></script>

这里需要尤其注意，官方默认给你的标签是：

<script type="text/javascript" src="http://api.map.baidu.com/api?v=3.0&ak=您的密钥"></script>

但是这种连接方法会导致浏览器报以下警告信息：

A parser-blocking, cross site (i.e. different eTLD+1) script, https://api.map.baidu.com/getscript?v=3.0&ak=密钥密钥密钥密钥&services=&t=20181029164750, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message. See https://www.chromestatus.com/feature/5718547946799104 for more details.

在srcipt标签中改用getcript方式可以解决这个问题 

然后再vue中新建一个map.vue文件，代码如下：

<template>
  <div id="allmap" ref="allmap"></div>
</template>

<script>

export default {
  name: 'Map',
  mounted() {
      this.ready();
  },
  methods: {
    ready: function() {
      var map = new BMap.Map("allmap");    
      var point = new BMap.Point(116.404, 39.915);    
      map.centerAndZoom(point, 15);    
      window.setTimeout(function(){  
          map.panTo(new BMap.Point(116.409, 39.918));
      }, 2000);
    }
  }
};

</script>

<style>
#allmap{
  height: 300px;
  width: 500px;
}
</style>
