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);
});
},
