I am using cesium with angular. I need to know where is built the request url for GetFeatureInfo in cesium but i cannot find it. For the context, what I want to do is display featureInfo on click on the map. But the request sent is using x and y parameters for coordinate and what I would like is replace them by i and j. Moreover, I would like to get bbox information present in this same request to display them. If someone could help me ! Thank you !

Are you asking in WebMapServiceImageryProvider's getFeatureInfo? – ZhefengJin Oct 21 '21 at 01:34

Yes ! I am using it for getMap, but it does not work for getFeatureInfo, in fact the request is sent with params x and y instead of i and j. So, I tried to build the request alone, but I am blocked with the bbox and the i and j coordinate. I do not know where to find it. Or maybe if you know how to replace x,y by i,j ? – Fab83i Oct 21 '21 at 07:11

The request is actually made in UrlTemplateImageryProvider.js's function pickFeatures.
This is a call stack screenshot in this sample.

Thank you for your answer, should i change name param x and y for i and j in this file ? – Fab83i Oct 21 '21 at 12:33

It is strange, I guess it is not coming from `buildPickFeatureResource()` because i commented this function and the request is still sent with all the params – Fab83i Oct 21 '21 at 12:51

Ok, First of all, thank you @ZhefengJin !
Due to your answer, I have checked the UrlTemplateImageryProvider.js, but the answer was not there. Nevertheless, It guides me to WebMapServiceImageryProvider.js. There, I noticed that x and y coordinate are assigned to x={i} and y={j} in pickFeatureParams.
I tried to add new param in this var but it did not work, I still do not understand why.
But I have tried to had my new param in my getFeatureInfoParameters using the same value, thinking that it will be passed in webMapServiceImageryProvider too and be assigned the same way.
And it works for me.
