Hi,

Have you tried to request geojson with its MIMETYPE as
&format=application/json; subtype=geojson ?

running with GeoJSON. But I always get back an empty response. I tried
several approaches and my WFS runs with a GML response. So maybe somebody
could give me hint. Here is my mapfile:

 

MAP

#    FORMATOPTION "FORM=SIMPLE"

#  END

 

OUTPUTFORMAT

      NAME "geojson"

      DRIVER "TEMPLATE"

      FORMATOPTION "FILE=/home/test/messtischblatt.js"

      MIMETYPE "application/json; subtype=geojson"

END

                "wfs_getfeature_formatlist" "geojson"

    END

    END

  END

 

END # MAP#  Tile Index

 

I test it with a couple of approaches. It tried both Outputformats and both
ways of defining a postgis data source. But in any case I get back an empty
response. With the template approach I used the following template:

 

[resultset layer=test]

{

                "type": "FeatureCollection",

                "features": [

                               [feature trimlast=","]

                               {

                                               "type": "Feature",

                                               "id": "[id]",

                                               .

                               }

                               [/feature]

                ]

}

[/resultset]

 

I run my mapserver also with DEBUG level 5. I got the following log output:

 

[Mon Jul 21 18:10:21 2014].528584 msFreeMap(): freeing map at 0x19447b0.

[Mon Jul 21 18:10:22 2014].387718 CGI Request 1 on process 4362

[Mon Jul 21 18:10:22 2014].521952 mapserv request processing time (msLoadMap
not incl.): 0.134s

 

My test request is:

 

http://localhost/cgi-bin/mtbows?map=./test.map
<http://localhost/cgi-bin/mtbows?map=./test.map&SERVICE=WFS&VERSION=1.0.0&RE
QUEST=getfeature&TYPENAME=test&MAXFEATURES=100&srsname=EPSG:900913&bbox=1518

612,7384239.639015725&outputformat=geojson

 

Could somebody give me an advice?

 

Kind regards, 

 

JM
