[qgis-qwc2] GetMap request from QWC2 miss map-parameter

Thu Mar 28 08:06:06 PDT 2019

Yes, I thougt so, too. But actualy it did not take effect in getfeatureinfo.

Using "map=" instead of "MAP=" fixed this for getmap, although the bbox in the request url is still xmin,ymin,xmax,ymax, so it is adapted.

I also edited "map=" of the url in themesConfig.jason, but after compiling themes.json only in the line "url" it is written in lower case, "legendUrl", "featureInfoUrl" and "printUrl" still have a capital letter "MAP=". ("legendUrl" is not bothered by this, as seen before.) Editing these to lowercase by hand has no effect in QWC, though.

Anyway, I will complie QWC2 again with your fix and see. Does this fix already cover the case sensitiveness of "map=" in the server url or do I have to file an issue?

Everything works: I get the QWC, it displays my theme showing the tools and the background layer and even the legend graphics are displayed. But the qgs-layers do not appear in the map!
