Re: [MapServer-users] Link in SLD doc returns an exception

2023-01-01 Thread Brent Fraser 
Hi Jeff,

I've filed an Issue in the docs.I haven't looked at the Mapserver code yet, 
but do you have any insight as to why I would get a "Cross-Origin Request 
Blocked" error from the foreign server when I include the SLD body (not the 
URL) in the get request using the SLD_BODY= parameter?

Thanks!
Brent

Happy new year Brent,

I have been updating the demo server with big changes, so your timing is
good: if you don't mind, it helps me if you file this as a ticket in the
documentation repository (I'll then tag it there as a demo server
ticket) : https://github.com/MapServer/MapServer-documentation

Thanks,

-jeff

Re: [MapServer-users] Link in SLD doc returns an exception

2022-12-31 Thread Brent Fraser 
Bjørn,

Thanks for the info.  I'm not sure if I should file an Issue on the doc for the 
broken link, or on the demo for the missing file (no public GitHub repository 
for the demo?).

While testing the GeoMoose/OpenLayers client, I did see foreign WMS servers 
(not under my control) cause a "Cross-Origin Request Blocked" error.  This was 
unexpected as I had encoded the XML SLD document and included it in the GET 
request parameter SLD_BODY.  I could understand getting the error if I had used 
the alternative method of instead using SLD=http://... to reference an SLD 
document somewhere on the web, but I did not use that method.  I even removed 
the reference links in the header of the SLD, but I got the same error.

Thanks again!
Brent Fraser

The error message is correct,
https://demo.mapserver.org/ogc-demos/map/sld/sld_line_simple.xml returns a 404
Page not found, The root folder at /ogc-demos/ has been removed at some point.

Be aware though, that not all WMS-servers allow (by configuration) external
hosted SLD-files due to potential XXE (XML eXternal Entity) vulnerability,

Also might be of interrest: the Mapserver implementation of GetStyle-request
(return SLD for a given layer) has some limitations on line-symbols where
images (png) are placed along the line symbol, and same with polygon fills
using a repeated png-file as fill - but simple polygon symbologies with a solid
fill color works as expected.
