Hi,

I would say that if your service is advertising geojson as a supported WFS
outputformat in GetCapabilities it should also support all standard WFS
requests and parameters and MaxFeatures is such an important parameter that
at least that should work for all outputformats. I suggest you to file a bug
into github https://github.com/mapserver. The developers woud like to get
also a repeatable test case with a small shapefile and mapfile.

Hi List,

 

i did some further testing and meet some unexpecting behavior. If I doesn't
use "MAXFEATURES" in my WFS-Request I get back a GeoJSON Response. Is that
wanted behavior or do I miss something?

 

Kind regards,


JM

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:

      MIMETYPE "application/json; subtype=geojson"

    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.

not incl.): 0.134s

 

My test request is:

Could somebody give me an advice?

 

Kind regards, 

 

JM
