前情提要
- 获得百度地图授权的ak密钥
- 引入echarts的百度地图
- 准备好echarts百度地图需要的数据
- 自定义百度地图的样式
- 去掉百度地图的logo
一、获取百度地图的ak密钥
首先得注册成为百度开发者 https://lbsyun.baidu.com/
成为开发者后，点击控制台
选择创建应用
创建完成之后就可以拿到ak密钥，我们将ak密钥在项目中使用，一般放在html模板，通过js引入
二、引入echarts的百度地图
在项目的全局额外引入
import 'echarts/extension/bmap/bmap';
三、准备数据
<template>
<div>
<Echart :options="options" id="mapchina" height="3.9063rem" width="3.9063rem"></Echart>
</div>
</template>
<script>
import Echart from '@/common/echart';
// import zhongxian from "../../../common/map/zhongxian";
// import zhongguo from '../../../common/map/zhongguo';
export default {
data() {
return {
