前言

很多朋友在学习和使用mars3d时，经常发现用的官方推荐组件，在实际应用中会出现很多问题。我用vuecli 4.0以上版本生成的vue项目，直接套用官方示例和官方组件会出现只显示地图，模型无法显示的问题。
如图
以下是我重构后的代码

一、map.vue

<template>
  <div
    :id="`mars3d-container${mapKey}`"
    :class="['mars3d-container', customClass, { 'mars3d-container-compare-rh': compare }]"
  ></div>
</template>

<script>
import Vue from "vue";

// 使用免费开源版本
import "mars3d/dist/mars3d.css";
import * as mars3d from "mars3d";

// 导入插件(其他插件类似，插件清单访问：http://mars3d.cn/dev/guide/start/install.html)
// echarts插件
// import 'mars3d-echarts'

// 为了方便使用,绑定到原型链，在其他vue文件，直接 this.mars3d 来使用
Vue.prototype.mars3d = mars3d;
Vue.prototype.Cesium = mars3d.Cesium;

export default {
  name: "mars3dViewer",

  props: {
    // 初始化配置参数
    url: String,

    // 地图唯一性标识
    mapKey: {
      type: String,
      default: "",
    },

    // 自定义参数
    options: Object,

    // 是否分屏显示
    compare: {
      type: Boolean,
      default: false,
    },

    // 是否插入到body元素上
    appendToBody: {
      type: Boolean,
      default: false,
    },

    // 自定义css类名
    customClass: {
      type: String,
      default: "",
    },
  },

  mounted() {
    if (this.appendToBody) {
      document.body.appendChild(this.$el);
    }

    if (this.mapKey) {
      this.initMars3d(this.options);
    } else {
      mars3d.Resource.fetchJson({ url: this.url }).then((data) => {
        this.initMars3d(data.map3d); // 构建地图
      });
    }
  },

  beforeDestroy() {
    this[`map${this.mapKey}`].destroy();
    delete this[`map${this.mapKey}`];
  },

  methods: {
    initMars3d(options) {
      if (this[`map${this.mapKey}`]) {
        this[`map${this.mapKey}`].destroy();
      }

      const mapOptions = {
        ...options,
        ...this.options,
      };

      // 创建三维地球场景
      var map = new mars3d.Map(`mars3d-container${this.mapKey}`, mapOptions);

      this[`map${this.mapKey}`] = map;

      console.log(">>>>> 地图创建成功 >>>>", map);

      // 挂载到全局对象下，所有组件通过 this.map 访问
      Vue.prototype[`map${this.mapKey}`] = map;

      // 绑定对alert的处理，右键弹出信息更美观。
      // window.haoutil = window.haoutil || {}
      // window.haoutil.msg = (msg) => {
      //   this.$message.success(msg)
      // }
      // window.haoutil.alert = (msg) => {
      //   this.$message.success(msg)
      // }

      // 抛出事件
      this.$emit("onload", map);
    },
  },
};
</script>

<style>
.mars3d-container {
