1.在 public/index.html 中引入

<!DOCTYPE html>
    <html lang="en">
    
    <head>
      <meta charset="utf-8">
      <meta http-equiv="X-UA-Compatible" content="IE=edge">
      <meta name="viewport" content="width=device-width,initial-scale=1.0">
      <link rel="icon" href="<%= BASE_URL %>favicon.ico">
      <title>title</title>
      <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=你自己的key值"></script>
    </head>
    
    <body>
      <div id="app"></div>
    </body>
    
    </html>

2.在vue文件中

<template>
      <div>
        <div class="map-box">
        <div class="map-header">
          <button @click="fixedPos">定位</button>
          <div>
            <label>当前纬度</label>
            <input v-model="latitude" />
          </div>
          <div>
            <label>当前经度</label>
            <input v-model="longitude" />
          </div>
          <div>
            <input v-model="keyWords" placeholder="请输入要搜索的地址" />
            <button @click="setPlace">搜索</button>
          </div>
        </div>
        <div id="map"></div>
      </div>
      </div>
    </template>
    <script>
      data(){
         
        return {
         
          map: null,
          local: null,
          mk: null,
          latitude: '',
          longitude: '',
          keyWords: ''
        }
      },
      mounted(){
         
        this.initMap()
      },
      methods: {
         
        initMap(){
         
          this.map = new BMap.Map('map')
          let point = new BMap.Point(116.404, 39.915)
          this.map.centerAndZoom(point, 12)
          this.map.enableScrollWheelZoom(true) // 开启鼠标滚轮缩放
          this.map.addControl(new BMap.NavigationControl())
        },
        // 点击定位-定位到当前位置
        fixedPos() {
         
          const _this = this
          const geolocation = new BMap.Geolocation()
          this.confirmLoading = true

            if (this.getStatus() == BMAP_STATUS_SUCCESS) {
         
              _this.handleMarker(_this, r.point)
              let myGeo = new BMap.Geocoder()
              myGeo.getLocation(new BMap.Point(r.point.lng, r.point.lat), function(result) {

          this.local.search(this.keyWords)
        },
        searchPlace() {
         
          if (this.local.getResults() != undefined) {
         
            this.map.clearOverlays() //清除地图上所有覆盖物
