[mapserver-users] Problems with getting geojson running as WFS response

[Rahkonen Jukka (Tike)]

Hi,

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

      MIMETYPE "application/json; subtype=geojson"
END

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&SERVICE=WFS&VERSION=1.0.0&REQUEST=getfeature&TYPENAME=test&MAXFEATURES=100&srsname=EPSG:900913&bbox=1518929.826549386,6766016.954331277,2693002.5808462612,7384239.639015725&outputformat=geojson

Could somebody give me an advice?

Kind regards,

JM
