[Qgis-user] wfs problems

[Juerg Lindauer]

Hi Jonathan

Thanks a lot for your answer. 

It was really something wrong in the configuartion of the server. Now
it works fine.

Cheers, 
Juerg

Hi Juerg,

I've looked into this and suspect the problem is actually with the 
configuration of the server.

This URL gets the GetCapabilities document and works:

https://map.geo.sz.ch/main/wsgi/mapserv_proxy?REQUEST=GetCapabilities&service=wfs


If you look in the document you'll see that it's declaring the
following 
URL as being for GetCapabilities:
<ows:Operation name="GetCapabilities">
<ows:DCP>
<ows:HTTP>
<ows:Get xlink:type="simple" 
xlink:href="https://map.geo.sz.ch/main/mapserv?"/>
<ows:Post xlink:type="simple" 
xlink:href="https://map.geo.sz.ch/main/mapserv?"/>
</ows:HTTP>
</ows:DCP>

Note the lack of "_proxy". In fact, if you search the document the 
string "_proxy" doesn't appear anywhere. But if you try that declared 
URL, you get a 403 - Forbidden:
https://map.geo.sz.ch/main/mapserv?REQUEST=GetCapabilities&service=wfs


So I suspect (this is a guess) that QGIS 3 is trying to ("correctly") 
use the declared URLs for the services, whereas QGIS 2 was ignoring
them 
and extrapolating them based on the base URL path. Which of these 
options is desirable is a tricky one - there are situations whether 
either work or don't.

Unfortunately the service doesn't declare any contact information to 
tell the server operator to fix it. But maybe you can find an email on

their web-page.

Cheers,
Jonathan
