[MapServer-users] WFS, OpenLayers and OUTPUTFORMAT explanations

[mathias cunault]

Hello,
Something that was never clear to me.
Here is a mapfile for a WFS definition:
MAP

OUTPUTFORMAT

# FORMATOPTION "FORM=SIMPLE"

FORMATOPTION "FORM=SIMPLE"
END #fin format

END #fin layer prescription

END #-----fin mapfile

It works fine in QGIS.
In a javascript file with the OpenLayers library, I can define a source
with an url function like this:
 url: function (extent) {
    return (
      "http://xxxx/cgi-bin/mapserv.exe?MAP=C:/.../vue_ol_prescription.map&"
+
      "service=WFS&version=1.1.0&request=GetFeature&typename=prescription&"
+
      "outputformat=geojson&SRSNAME=EPSG:2154&bbox=" +
      extent.join(",") +
      ",EPSG:3857"
    )

Why can't I use outputformat = application/json though it is permitted by
the outpuformat in mapfile layer definition ? I have an error :
"application.json  not permitted".
