arcgis for js 4.9 调用WMS出现 No 'Access-Control-Allow-Origin' 和Failed to load layer

Failed to load http://localhost:6080/arcgis/s ... ties: No 'Access-Control-Allow-Origin' header is present on the requested resource.

[esri.layers.WMSLayer] #load() Failed to load layer (title: 'Layer', id: '166f22bf542-layer-0')

出现上述两个问题始终没解决，请教各位了谢谢。
