Dear list,
@Jeff: Thanks for the tip. But I need a programmatic way using the
Python API how to extract the "GetMap" URL.
Currently I fixed my problem with OWSlib:
```
d = parse_qs(source)
url_get_capabilities = d['url'][0]
layers = d['layers'][0]
# request getMap URL via OWSLib
wms = WebMapService(url_get_capabilities)
url_get_map = wms.getOperationByName('GetMap').methods[0]['url'] ```
However, I am not that happy with this approach, because OWSlib makes
another request to the server. I mean, QGIS obviously knows the URL
already, but I cannot easily access it Python. Does anyone else have an
idea how the retrieve the "GetMap" URL? Thanks and best wishes, Jakob

Try Richard's great 'QGIS Network Logger' plugin, to see all WMS
requests. I've recorded several options here to grab the GetMap url:

Dear list,
I want to extract the "GetMap" URL from WMS layers. For most of the
WMS layers I can extract it from "layer.source()". However this does
not work for WMS layers where "GetMap" and "GetCapabilities" is
different. Like for this layer:
https://www.geoportal.rlp.de/mapbender/php/wms.php?inspire=1&layer_id=69694&withChilds=1&INSPIRE=1&;
The only place where I can find the "GetMap" URL is inside the
"layer.htmlMetadata()" document. From there the URL can be extracted
using REGEX. But every localization of QGIS (e.g. German, French ...)
have different terms for the surrounding "GetMap" HTML element. This
makes this approach quite tricky.
Is there any more elegant solution how to retrieve the "GetMap" URL
from WMS layers?
Thanks in advance and best wishes,
Jakob
