WMTS Custom Request Fields

[yuanlei88]

I met my requirements when using the CesiumWebMapTileServiceRasterOverlay component to load WMTS, but for some WMTS services, verification keys need to be added, such as the<tk=>field. However, based on the internal combination method, if I add this code snippet to the URL, there will be xxx/wmts? Tk=xxx? Request=GetTile&version=1.0.0&service=WMTS&format=tiles&layer=img&style=&tilematrixset=w&tilematrix=3&tilerow=4&tilecol=15. The strange combination of URLs mentioned above can cause request exceptions. Can you add a custom field combination so that I can add my necessary verification information
