传单是开源且免费的。但是,传单站点上的示例使用MAPBOX呈现地图。MAPBOX比Google Map(Mapbox定价)更昂贵。问题是:有人可以真正免费使用传单吗?
您可以免费使用传单库,只有示例中使用的tileprovider,mapbox中使用的钱才能为瓷砖提供资金。您只需要像OpenStreetMap这样的免费tileprovider:
var map = new L.Map('leaflet', {
center: [0, 0],
zoom: 0,
layers: [
new L.TileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
'attribution': 'Map data © <a href="http://openstreetmap.org">OpenStreetMap</a> contributors'
})
]
});
