[mapserver-users] [EXTERNAL] RE: Multiple Styles for a LAYER/CLASS

Tue Sep 15 01:43:33 PDT 2020

Some example urls that makes it easier to test.  
Change "/home/lars" to where you placed the files. 

http://localhost/cgi-bin/mapserv?
map=/home/lars/style_test/style_test.map
&SERVICE=WMS
&REQUEST=Getmap
&VERSION=1.1.1
&LAYERS=square,circle
&styles=green,grey
&srs=EPSG:4326
&BBOX=0,0,20,15
&FORMAT=image/png
&WIDTH=200
&HEIGHT=150

http://localhost/cgi-bin/mapserv?
map=/home/lars/style_test/style_test.map
&SERVICE=WMS
&REQUEST=Getmap
&VERSION=1.1.1
&LAYERS=ST
&styles=color
&srs=EPSG:4326
&BBOX=0,0,20,15
&FORMAT=image/png
&WIDTH=200
&HEIGHT=150

http://localhost/cgi-bin/mapserv?
map=/home/lars/style_test/style_test.map
&SERVICE=WMS
&REQUEST=GetCapabilities
&VERSION=1.1.1

Have fun / Lars
