Wrong query to WMS (WMS.GetFeatureInfo)

[alexbruy]

Seems that QGIS send wrong query to WMS when used Identify tool. Error message

Результат WMS-определения для 258, 213

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

/WMS_exception_1_1_1.dtd"> <ServiceExceptionReport version="1.1.1" >   <ServiceException>
      java.lang.NullPointerException
null
</ServiceException></ServiceExceptionReport>

When we look at query:

http://gis.gis-lab.info:8080/geoserver/wms
    ?SERVICE=WMS&SERVICE=WMS
    &VERSION=1.1.1&REQUEST=GetFeatureInfo
    &BBOX=77.305313,49.465485,89.865570,55.358971
    &SRS=EPSG:4326&WIDTH=500&HEIGHT=235
    &LAYERS=geosample%3Aoopt&STYLES=
    &FORMAT=image/gif&TRANSPARENT=TRUE
    &QUERY_LAYERS=geosample174Aoopt
    &INFO_FORMAT=text/plain&X=458&Y=174

In line QUERY_LAYERS instead of 174A must be semicolon (:). Also there is duplicated SERVICE=WMS

Discussion is Russian on GIS-Lab: ​http://gis-lab.info/forum/viewtopic.php?f=14&t=3838 (several last posts)

Tested on QGIS 1.2 (svn 11481M) and QGIS 1.3 (svn 11496, 11518M)

Replying to alexbruy:

Fixed in r11522

• the double SERVICE=WMS is harmless. The WMS server probably shouldn't already include SERVICE=WMS in it's OnlineResource in the GetCapabilities response.

• the other problem was that the percent encoding turned that colon in your layer into %3A and the %3 was in turn wrongly replaced with the x coordinate.

• the WMS provider now also treats the WMS response a UTF-8. That should be harmless when it's plain ascii and helps in your case. I now get:

WMS identify result for 375, 289:

Whatever that means ;)
