实现
1、插件地址
https://github.com/Norkart/Leaflet-MiniMap
2、注意这里的官方说明
不要将小地图组件添加到主地图的图层上，需要单独声明一个图层。
3、下载源码引入所需的js、css、image文件
4、修改css中图片的路径
5、完整示例代码
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>leaflet迷你地图显示</title>
<link rel="stylesheet" href="https://unpkg.com/leaflet@1.7.1/dist/leaflet.css" />
<link rel="stylesheet" href="./css/Control.MiniMap.min.css" />

<body>
<div id="map"></div>
<script type="text/javascript" src="https://unpkg.com/leaflet@1.7.1/dist/leaflet.js"></script>
<script type="text/javascript" src="./js/Control.MiniMap.min.js"></script>
<script type="text/javascript">
var map = L.map('map');
var osmUrl='http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png';
var osmAttrib='Map data © OpenStreetMap contributors';
var osm = new L.TileLayer(osmUrl, {minZoom: 5, maxZoom: 18, attribution: osmAttrib});
map.addLayer(osm);
map.setView(new L.LatLng(36.09, 120.35),10);
//Plugin magic goes here! Note that you cannot use the same layer object again, as that will confuse the two map controls
var osm2 = new L.TileLayer(osmUrl, {minZoom: 0, maxZoom: 13, attribution: osmAttrib });
var miniMap = new L.Control.MiniMap(osm2, { toggleDisplay: true }).addTo(map);
</script>
</body>
