[MapProxy] Mapproxy 1.12 issue restful requests (GFI)

Thu Jan 28 03:47:37 PST 2021

Dear List,

I have a issue between Mapproxy 1.12.0 and Mapserver 7.4.3 with restful requests

When I use the WMS(?) KVP Capabilities from Mapproxy (http://localhost/mapproxy/service?REQUEST=GetCapabilities) in e.g. QGIS, everything works fine. The legend and the GetFeatureInfo (GFI) are avaiable and working for the WMTS Layer.

The GFI request is similar as in Mapserver WMS,
http://localhost/mapproxy/service?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo&BBOX=359590.9848198993713595,5668915.14138658251613379,361421.80612308223498985,5670043.28831636067479849&CRS=EPSG:25832&WIDTH=568&HEIGHT=350&LAYERS=verkehrsweg_wmts&STYLES=&FORMAT=image/png&QUERY_LAYERS=verkehrsweg_wmts&INFO_FORMAT=text/html&I=268&J=176&FEATURE_COUNT=10

http://localhost/cgi-bin/mapserv64/mapserv.fcgi?map=c:/srv/mapfiles/verkehrswege.map&language=ger&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&BBOX=359590.9848198993713595,5668915.14138658251613379,361421.80612308223498985,5670043.28831636067479849&SRS=EPSG:25832&WIDTH=568&HEIGHT=350&LAYERS=Verkehrsweg&STYLES=&FORMAT=image/png&QUERY_LAYERS=Verkehrsweg&INFO_FORMAT=text/html&X=266&Y=176&FEATURE_COUNT=10

But,

When I use the restful Mapproxy Service (http://localhost/mapproxy/wmts/1.0.0/WMTSCapabilities.xml), no Legend and GFI works

The LegendURL is not exist in the Capabilities, when I copy the WMTSCapabilities.xml to local an add the LegendURL manually, it works from the local file.
      <Style>
        <ows:Title>Style für Verkehrsweg</ows:Title>
                              <ows:Identifier>default</ows:Identifier>
        <LegendURL format="image/png" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:type="simple" xlink:href="http://localhost/mapproxy/service?styles=&layer=verkehrsweg&service=WMS&format=image/png&sld_version=1.1.0&request=GetLegendGraphic&version=1.1.1 "/>
      </Style>

But my biggest problem is:

When I request the restful service, the restful tile request works
http://localhost/mapproxy/wmts/verkehrsweg_wmts/wmtsgrid/09/146/324.png

but the GFI request on the same tile not
http://localhost/mapproxy/wmts/verkehrsweg_wmts/wmtsgrid/09/146/324/38/142.html

Mapserver says:
msQueryByPoint(): Search returned no results. No matching record(s) found.

Unfortunally I can´t see the request from Mapproxy to Mapserver in my logs or the HTTP Debugger.

Using http://localhost/mapproxy/service?REQUEST=GetCapabilities&SERVICE=WMTS in QGIS, the legend and GFI are also not available
the answer for GFI is:
GetFeatureInfo-Fehler Error transferring http://localhost/mapproxy/service?SERVICE=WMTS&REQUEST=GetFeatureInfo&VERSION=1.0.0&LAYER=verkehrsweg_wmts&STYLE=default&INFOFORMAT=text/html&TILEMATRIXSET=wmtsgrid&TILEMATRIX=10&TILEROW=511&TILECOL=171&I=168&J=214 - server replied: Internal Server Error

-<ows:Exception exceptionCode="NoApplicableCode">
<ows:ExceptionText>missing parameters ['format']</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>

adding the FORMAT Parameter to the URL manually, Mapserver says again
msQueryByPoint(): Search returned no results. No matching record(s) found

I don´t know if this ist a Mapproxy or Mapserver problem, maybe has someone a solution for this issue.

My Mapproxy yaml configuration:

in the http://localhost/mapproxy/service?REQUEST=GetCapabilities&SERVICE=WMTS
are no LegendURL or ResourceURL are generated

Thanks in advance,
