[Qgis-user] QGIS Server a GetFeatureInfo request problems. Not sure what I am missing.

[Peter Len]

I am using QGIS Server that is running in my OSGeo Apache web server (on Windows 7).  Not sure what version the QGIS Server is but it was from the latest OSGeo4W installer.  I was testing an OpenLayers client to view a QGIS Desktop project file over WMS from the QGIS Server.  All seems good with that.  For example, my OpenLayers code to get  this looks like:

var url = "http://localhost:8090/qgis/qgis_mapserv.fcgi.exe";
var layer = new OpenLayers.Layer.WMS( "Main Layer", url, {
	layers: 'table_poly,location_view',
	format: 'image/png',
   },
   {
       buffer: 1, 
	isBaseLayer: true, 
       graphicZIndex: 0, 
   }
);
map.addLayers([layer]);

With the above, I can view my layers within OpenLayers.  My next test was to see if I could get the feature info from items on my layers.  I found an example of how to make this call in OpenLayers and it looks like:

var info = new OpenLayers.Control.WMSGetFeatureInfo({
                          url: url,
                          title: 'Identify features by clicking',
                          queryVisible: true,
                          eventListeners: {
                            getfeatureinfo: function(event) {
                                alert("Got feature info");                         
                            }
                         }
                      });
map.addControl(info);
info.activate();

When I tried this, I didn't get anything except a spinning cursor.  I then tried another test to see if that was the correct way to ask for feature info so I changed the URL for the layers to get the layers from my GeoServer rather than from QGIS Server (the project file got these layers initially from GeoServer so we are talking about the same layer source).  That worked just fine and I was able to get individual feature information.  After switching back to point to my QGIS Server I started to look at the Apache web server logs and the GeoServer output screen.  The Apache logs didn't list anything related but the GeoServer console listed the following:

20 Jan 13:06:57 INFO [geoserver.wms] -
Request: getServiceInfo
20 Jan 13:06:57 INFO [geoserver.wms] -

        Namespace = Postgres
        UpdateSequence = null
        Request = GetCapabilities
        Version = 1.3.0
        RequestCharset = null
        RawKvp = {SERVICE=WMS, REQUEST=GetCapabilities}
        Get = false
        BaseUrl = http://localhost:8080/geoserver/

ment.
20 Jan 13:06:57 WARN [wms.capabilities] - Map output format application/xml does
 not include mime type in output format names. Will be excluded from capabilitie
s document.

This occurred just after clicking on my OpenLayers map, which in turn triggered the WMSGetFeatureInfo request.  I noticed that there was no reference to GetFeatureInfo.  So... I am not sure what to make of this.  Should my OpenLayers call be something different?  Does QGIS Server not serve up features from layers within a project file?  I had found some references concerning a problem with QGIS Server and GetFeatureInfo calls (Bug #8656) but the request URL listed seemed to be something different than my scenario via OpenLayers and to a project file layer.  

Any thoughts?
