这可以在一个html文件中完成。您必须使用L.geoJson功能。查看代码段：
var map = L.map('mapid').setView([39.10, -76.60], 12);
L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpandmbXliNDBjZWd2M2x6bDk3c2ZtOTkifQ._QA7i5Mpkd_m30IGElHziw', {
id: 'mapbox.streets'
}).addTo(map);
