加载geoserver发布的wmts服务titlematrix错误

[liangyuan1]

使用wmtssource 加载geoserver 发布的wmts服务，titlemaxtrix ：直接返回数字，丢失 3857:类似的字段，如下图所示

实现代码：vue(2.6.14)
具体方法：
var orthoSource1 = new itowns.WMTSSource({
url: 'http://192.168.112.29:9090/geoserver2/cite/gwc/service/wmts?',
crs: 'EPSG:3857',
name: 'cite:csdmaWMTS3857',
tileMatrixSet: '3857',
format: 'image/png',
})
var orthoLayer1 = new itowns.ColorLayer('Ortho1', {
source: orthoSource1,
})
view.addLayer(orthoLayer1)
结果问题：（1）存在跨域，但是使用oepnlayer和cesium加载不存在，（2）瓦片请求地址不对，主要是TILEMATRIX字段，正确的应该是TILEMATRIX=tileMatrixSet+“:”+tileMatrixSet

Hello, why would we have the tileMatrixSet in the tileMatrix ? This info is already carried in the tileMatrixSet.
Do you have a spec for this ?
Thank you

ALSO, you must type in English so it makes it easier for everyone involved in this project ( english isn't my primary language neither ;) )

This is the rule for publishing services on Geoserver. Geoserver is an open-source map server that is widely used

Hi,
Geoserver does indeed format tileMatrixSet identifiers this way. You can use the tileMatrixCallback parameter to adress this problem : tileMatrixCallback: (zoomLevel => "3857:" + zoomLevel).

let orthoSource1 = new itowns.WMTSSource({
url: 'http://192.168.112.29:9090/geoserver2/cite/gwc/service/wmts?',
crs: 'EPSG:3857',
name: 'cite:csdmaWMTS3857',
tileMatrixSet: '3857',
format: 'image/png',
tileMatrixCallback: (zoomLevel => "3857:" + zoomLevel)
});
