openlayers加载天地图和高德地图

一、天地图部分

1、在vue中安装openlayers

npm i --save ol

这里说的vue是基于脚手架构建的。新建个页面，也就是vue文件，配置好路由。接着就是可以直接放入我的代码运行显示了。

vue利用openlayers加载天地图和高德地图
<template>
  <div class="wrapper">
    <div>天地图</div>
    <div class="map" id="olMap"></div>
  </div>
</template>
<script>
import "ol/ol.css";
import {
  Tile as TileLayer } from "ol/layer";
import XYZ from "ol/source/XYZ";
import {
  defaults as defaultControls } from "ol/control";
import Map from "ol/Map.js";
import View from "ol/View.js";
export default {
  data() {
   return {
      map: null,
      parser: null,
    };
  },
  mounted() {
    this.initMap();
  },
  methods: {
    initMap() {
     const map = new Map({
       target: "olMap",
        view: new View({
 
          center: [0, 0], //中心点经纬度
          zoom: 4, //图层缩放大小
          projection: "EPSG:4326",
        }),
        controls: defaultControls({
          zoom: true,
          attribution: false,
          rotate: false,
        }),
      });
      this.map = map;
      // 添加地图
      let url = "http://t{0-7}.tianditu.com/DataServer?x={x}&y={y}&l={z}";
      url = `${
   url}&T=vec_c&tk=替代你的key`;
      const source = new XYZ({
     url: url,
        projection: "EPSG:4326",
      });
      const tdtLayer = new TileLayer({
        source: source,
      });
      this.map.addLayer(tdtLayer);
      // 添加注记
      url = "http://t{0-7}.tianditu.com/DataServer?x={x}&y={y}&l={z}";
      url = `${
   url}&T=cva_c&tk=替代你的key`;
      const sourceCVA = new XYZ({
        url: url,
        projection: "EPSG:4326",
      });
      const tdtcvaLayer = new TileLayer({
        source: sourceCVA,
      });
      this.map.addLayer(tdtcvaLayer);
    },
  },
};
</script>
<style scoped>
.map {
  width: 100%;
  height: 100vh;
}
</style>

天地图就可以显示出来了。

二、高德地图部分

相对于天地图，高德地图就容易多了，直接上代码

<template>
  <div class="wrapper">
    <div>高德地图</div>
    <div id="map"></div>
  </div>
</template>
<script>
import {
 Map,View,Feature} from 'ol'

import * as olProj from 'ol/proj'
import {
 Point} from 'ol/geom'
import {
  Style, Fill, Stroke, Circle as sCircle } from "ol/style";
// 添加图层
import Tilelayer from 'ol/layer/Tile'
import {
 Vector as VectorLayer} from 'ol/layer'
import {
 XYZ,Vector as VectorSource} from 'ol/source'
//引入样式文件
import "ol/ol.css"
export default {
  data() {
  return {
    map:null
    }
  },
  mounted() {
  this.init();
   this.setMarker();
  },
  methods: {
    init(){
       this.map=new Map({
         target:'map',
         layers:[new Tilelayer({
           source: new XYZ({
               url:'https://wprd0{1-4}.is.autonavi.com/appmaptile?lang=zh_cn&size=1&style=7&x={x}&y={y}&z={z}',
           })
         })
         ],
        view:new View({

            // 将西安作为地图中心 
            // olProj.fromLonLat方法将经纬度转换成对应的坐标
          center:olProj.fromLonLat([108.945951, 34.465262]),
          zoom:2
        }),
       })
    },
    setMarker(){
        let _style = new Style({
            image:new sCircle({
                radius:10,
                stroke:new Stroke({
                    color:"#fff",
                }),
                fill: new Fill({
                    color:'#3399CC',
                }),
            }),
        });
        let _feature = new Feature({
 
            geometry:new Point(olProj.fromLonLat([108.945951, 34.465262])),
        });
        _feature.setStyle(_style);
        let _marker = new VectorLayer({

            source: new VectorSource({
               feature:[_feature],
            }),
        });
        this.map.addLayer(_marker);
    },
  },
}
</script>
<style scoped>
  #map{
      /* 屏幕宽高 */
    width: 100vw;
    height: 100vh;
  }
</style>
