vue3开发高德地图
在vue3的index.html
使用动态注入地址名和key
<html lang="en"><head><meta charset="UTF-8" /><link rel="icon" type="image/svg+xml" href="/vite.svg" /><meta name="viewport" content="width=device-width, initial-scale=1.0" /><title>Vite + Vue</title></head><body><div id="app"></div><script type="text/javascript" src="%VITE_MAP_ULR%/maps?v=1.4.6&key=%VITE_MAP_KEY%"></script><script type="text/javascript" src="%VITE_MAP_ULR%/maps?v=1.4.15&plugin=AMap.Driving&plugin=AMap.ControlBar&plugin=AMap.MapType,AMap.PolyEditor,AMap.CircleEditor,AMap.HeatMap&key=%VITE_MAP_KEY%"></script><script type="text/javascript" src="%VITE_MAP_ULR%/maps?v=1.4.6&plugin=AMap.DistrictSearch&key=%VITE_MAP_KEY%"></script><script type="text/javascript" src="%VITE_MAP_ULR%/maps?v=1.4.6&plugin=AMap.MouseTool&key=%VITE_MAP_KEY%"></script><script type="text/javascript" src="%VITE_MAP_ULR%/maps?v=1.4.15&plugin=AMap.ControlBar&key=%VITE_MAP_KEY%"></script><script type="module" src="/src/main.js"></script></body>
</html>在对应的开发环境中注入对的地址和key,比如在.env.development(开发环境)
VITE_NODE_ENV='development'
# 后端链接地址
VITE_APP_URL='http://www.taobao.com'
# 如果使用了CJS,不知道报错日志，脚本显示报错日志 --vite官网/指引/故障排除/CJS
VITE_CJS_TRACE=true
# 忽略CJS警告
# VITE_CJS_IGNORE_WARNING=true
# 高德API
VITE_MAP_ULR=''
# 高德地图key
VITE_MAP_KEY=''因为请求高德会报跨域，所以在vite中使用代理地址
server: {open: true,// port: 3000,proxy: {'^/maps': {target: 'http://webapi.amap.com/',changeOrigin: true}}},在对应的页面中引入高德地图

封装的高德方法
/***? 加载地图*/
import { reactive } from 'vue'
const data = reactive({map: '',polyEditor: '',mouseTool: '',polygon: '', // 覆盖物location: {lng: '',lat: ''},path: []
})
export const mapInit = (mapConfig, dom) => {data.map = new AMap.Map(dom, {viewMode: mapConfig.viewMode, // 默认使用 2D 模式，如果希望使用带有俯仰角的 3D 模式，请设置 viewMode: '3D'zoom: mapConfig.zoom, // 初始化地图层级center: mapConfig.location, // 初始化地图中心点})data.map.on("click", showInfoClick)return data.map
}/***@description 获取点击的经纬度*/export function showInfoClick(e) {console.log('e', e)data.location.lng = e.lnglat.getLng() //记录最后一次点击的经纬度data.location.lat = e.lnglat.getLat()
}/***! 添加画图工具*/export const addDrawingManager = () => {if (data.polyEditor) {//判断存在多边形围栏就先取消编辑并清除之前画的多边形围栏data.polyEditor.close()}data.polyEditor = new AMap.PolygonEditor(data.map)data.polyEditor.on('add', function (attr) {console.log(data);let polygon = attr.target;data.polyEditor.addAdsorbPolygons(polygon)polygon.on('dblclick', () => {data.polyEditor.setTarget(polygon);data.polyEditor.open()})})return data.polyEditor}
