Hi, Kevin,  
Thanks for the reply.  
The ‘GetCapabilities’ service returned by the server as follows.

And I put in the such url in my browser as"[http://t0.tianditu.gov.cn/img\_c/wmts?tk=mytoken&request=GetTile&version=1.0.0&service=WMTS&format=tiles&layer=img&style=default&tilematrixset=c&tilematrix=1&tilerow=0&tilecol=0](http://t0.tianditu.gov.cn/img_c/wmts?tk=mytoken&request=GetTile&version=1.0.0&service=WMTS&format=tiles&layer=img&style=default&tilematrixset=c&tilematrix=1&tilerow=0&tilecol=0)", I get the result.

why CesiumWebMapTileServiceRasterOverlay can not load the RasterOverlay? I still think the problem is the tk. My server requires the url to be " [http://t0.tianditu.gov.cn/img\_c/wmts?tk=mytoken](http://t0.tianditu.gov.cn/img_c/wmts?tk=mytoken)". Yet the CesiumWebMapTileServiceRasterOverlay has no place to hold the tk. The CesiumWebMapTileServiceRasterOverlay just adds another ‘’?" behind the url，and it might cause the problem. Would it be reasonable to add a variable member such as “tk” to wmtsOptions in the source code?
