vue + 高德地图

2024-09-23 09:17:01 浏览数 (3)

官方文档:

https://lbs.amap.com/api/javascript-api-v2/summary

API 文档 :

http://https://lbs.amap.com/api/javascript-api-v2/documentation

个别接口有每日调用限制,如不满足使用需要购买服务包 流量限制说明-地图 JS API 2.0 | 高德地图API*

准备工作:

(注册成为高德开发者进入应用管理,创建新应用,新应用中添加 key,服务平台选择 Web端(JS API))

具体示例:准备-地图 JS API 2.0 | 高德地图API

Web端使用:

安装高德地图加载器插件 :

代码语言:bash复制
npm  i  @amap/amap-jsapi-loader -S

具体思路:VUE文件created中初始化调用

1、初始化加载地图方法

2、如需实时跟踪点位信息需要加上初始化动态刷新坐标的方法(可以采用前端页面轮询或后端Websocket主动发送的方式)(websocket参考上篇文章)

主要方法(初始化加载地图)
代码语言:javascript复制
AMapLoader.load({
        key: "xxxxxxxxxxxxxxxxxxxxxxxxxxx",             // 申请好的Web端开发者Key,首次调用 load 时必填
        version: "2.0",      // 指定要加载的 JSAPI 的版本,缺省时默认为 1.4.15
        plugins: ['AMap.InfoWindow', 'AMap.Marker', 'AMap.Polyline', 'AMap.Icon'],       // 需要使用的的插件列表,如比例尺'AMap.Scale'等
      }).then((AMap) => {
        this.map = new AMap.Map("container", {  //设置地图容器id
          viewMode: "2D",    //是否为3D地图模式
          zoom: 12,           //初始化地图级别
          center: [117.125809,36.679151], //初始化地图中心点位置
        })
         //这里添加需要的地图api、如下图完整代码
         }).catch((error) => {
        console.log("地图加载失败!",error);
      });
},
