我试着在铯地球仪上添加wms层，以便在android应用中显示。我使用的是 翩翩 插件v0.3.21，geoserver v2.15.1和铯v1.69。
我在真实设备和仿真器中得到了这个错误和警告。

我可以试着把你的代码放到Cesium Sandcastle中，看看是否能用。
这里有一个Cesium Sandcastle显示本地GeoServer地图的例子。
如果铯沙堡失败。你必须在GeoServer中启用CORS。. 进入GeoServer的webapps/geoserver/WEB-INF/web.xml，取消所有CORS部分的注释，然后重新启动GeoServer。https:/docs.geoserver.orglatestenuserproductioncontainer.html#enable-cors。
