Yes, GetStyle and GetStyles should be split. As SLDVER is optional, it
might be good to raise an exception only if wms version is != 1.1.1 (or
if other required parameters are missing).

Hi
QGIS server has its own GetStyle method because implementation of
the server started based on WMS 1.3/SLD1.1. It seems OGC GetStyles
is only present in WMS1.1.1/SLD1.0 and has been dropped
afterwards. So it seems to me the bug in the server code is that
GetStyles is directed to QGIS GetStyle.
I'm aware that WMS 1.1.1/SLD1.0 are very frequently used. So a
patch to add OGC GetStyles behaviour for 1.1.1 is very welcome.
Hi Marco,
thank you for clarifying, you are absolutely right and it seems that
it was dropped after 1.0, my issue is related to "GetStyles" request,
(please notice the trailing "s"), I used this documentation
(02-070_Styled_Layer_Descriptor_Implementation_Specification.pdf,
http://portal.opengeospatial.org/files/?artifact_id=1188) :
13.1. GetStyles
The GetStyles operation is used to retrieve user-defined styles from a
WMS. The
parameters of the HTTP-GET method are defined as follows:
Parameter Required Description VERSION Required
Version as required by OGC interfaces.
REQUEST Required Value must be “GetStyles”.
LAYERS Required Comma-separated list of named layers for which to
retrieve style
descriptions.
SLDVER Optional The SLD version requested for the SLD document. The
default is
to return the highest version supported by the server. If a version
is requested that the server does not support, then the next lower
supported version is supported by the server is returned, or the
server’s lowest supported version. This is similar to WMS version
negotiation.
If I understand this correctly, we should split GetStyle and GetStyles
calls and support the second one only if SLDVER is set and
SLDVER=1.0.0, raise an exception if not match.
GetStyles should then accept the following parameters:
REQUEST=GetStyles
LAYERS=comma separated list of TypeNames
SLDVER=1.0.0 (this seems the only version that supports GetStyles)
BTW: does anybody know what method took the place of GetStyles after
it was dropped?
