[Question]: Is there a way to configure WMS version for third party WMS layers?

[RaineEkman]

What is the question? (in English)

In my project there is a layer configured using the "Get images directly from WMS Server" checkbox. It won't show in the web client, and I can see in my browser dev tools that WMS 1.3.0 is tried. However, when I try manually any of the WMS 1.3.0 URLs I can see, I get this, indicating that the server doesn't support WMS 1.3.0:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE ServiceExceptionReport SYSTEM "http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd">
<ServiceExceptionReport version="1.1.1">
 <ServiceException>Unsupported WMS version</ServiceException>
</ServiceExceptionReport>

QGIS Desktop loads the layer fine, and checking it I can see that the URLs are WMS 1.1.1. I can't find a way in the Lizmap plugin to configure the version as 1.1.1. Should this even be possible or is only 1.3.0 supported?

Versions, safeguards, check summary etc

Can you check in your QGS file all occurences of the URL of your WMS to see if the VERSION is included in it ?

[Gustry]

Well, there are a few area where 1.3.0 is hardcoded : https://github.com/search?q=repo%3A3liz%2Flizmap-web-client%201.3.0&type=code

I tweaked the server settings in QGIS:

• Added ?VERSION=1.1.1 to the server connection
• Checked the "ignore GetXXXXURI reported in capabilities" options to keep the entered connection URL
• Re-added the layer
• Exported using the Lizmap plugin.

The version number went into both copies of the URL in the .qgs file. Now I get URLs with double version numbers in the web client:
https://<redacted>/TeklaOGCWeb/WMS.ashx?VERSION=1.1.1&REQUEST=GetMap&SERVICE=WMS&VERSION=1.3.0&FORMAT=image%2Fpng&STYLES=&TRANSPARENT=true&LAYERS=<redacted>&DPI=135&TILED=true&WIDTH=384&HEIGHT=384&CRS=EPSG%3A3067&BBOX=<redacted>

Some hardcoded version number should probably be replaced by something more flexible/smarter.

It's not just the version number in the HTTP call, but mainly parameters and response that should bec checked.
