MaplibreGL and WMS

[cotegeo]

Hello,

I know that question asked many times but I didn't find solution.

I work with MapboxGL/MaplibreGL and when I add WMS layer, the console returns all time

Access to fetch at 'https://wms.myurl.fr/qgis?map=projects/test_wms1.qgs&bbox=136975.15468703583,5371382.851655904,146759.09430753812,5381166.7912764065&format=image/png&service=WMS&version=1.3.0&request=GetMap&srs=EPSG:3857&transparent=true&width=256&height=256&layers=carte_moissac' from origin 'http://localhost' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

For information, this problem come from MaplibreGL (and lonely) because my WMS layer works with LeafletJS.

Headers are present ahead to my php file like that :

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: *");
header("Access-Control-Allow-Credentials: true");
?>
How do you go about it?

Thanks

Sylvain

Leaflet is using img html element, which doesn't need CORS enabled on the server.
Maplibre is fetching the image and pass it to the GPU so it doesn't use the same technology.
You need to enable CORS on your server in order to use this layer or have the maplibre code run from the same origin.
You can also disable CORS restriction in your browser, but that will only apply to you and not your users.
Good luck!

Thank you for your feedback. About the first solution, ie enable CORS server side, I don't know how to do that at the moment. Thanks

And another question : I complete the second solution, but I have a layer with tiles index. How disable this layer ? It's a parameter I have to disable server side ? (ie when I make my WMS layer with qgis ?) Thks. Sylvain

I don't understand the question, sorry...
