需求：根据后端返回的定位坐标数据实现定位渲染

1.效果图

2.准备工作,在main.js和index.js文件中添加以下内容

main.js
app.use(BaiduMap, {
    // ak 是在百度地图开发者平台申请的密钥 详见 http://lbsyun.baidu.com/apiconsole/key */
    ak: 'sRDDfAKpCSG5iF1rvwph4Q95M6tDCApL',
    // v:'3.0',  // 默认使用3.0
    // type: 'WebGL' // ||API 默认API  (使用此模式 BMap=BMapGL)
});

index.js
 <script type="text/javascript" src="https://api.map.baidu.com/getscript?v=3.0&ak=sRDDfAKpCSG5iF1rvwph4Q95M6tDCApL"></script>

3.html

<template>
  <div>
      <div id="main6"
         style="width:650px;height:400px;"></div>  
  </div>
</template>
