您好，您问题里说的是wms服务，但是我看您代码中的地址好像是rest服务的。

leaflet加载wms标准地图服务：http://support.supermap.com.cn:8090/iserver/iClient/forJavaScript/examples/leaflet/editor.html#WMSLayer

leaflet加载记载rest地图服务：http://support.supermap.com.cn:8090/iserver/iClient/forJavaScript/examples/leaflet/editor.html#01_tiledMapLayer4326

希望可以帮助到您。
