[mapserver-users] server geojson data as input to map file

[Thomas Gratier]

Hi Jeff,

Could be wrong but your exemple use a static GeoJSON file whereas flask
datasource would more probably be
http://urlflaskserver/my_end_point/layername.geojson

So

CONNECTIONTYPE OGRCONNECTION "name.json"DATA "layername"

would be

CONNECTIONTYPE OGRCONNECTION
"/vsicurl/http://urlflaskserver/my_end_point/layername.geojson"DATA
"layername"

FYI, above untested but considering it may work because it could inherit
from GDAL/OGR behaviour like below and already mentioned for other
datasources e.g
https://mapserver.org/input/virtual-file.html#configure-mapserver-layer

Be aware that remote consumption a least on ogrinfo need an url ending like
it's a file e.g
# Working because geojson extension in the url (so GDAL can guess it's a
GeoJSON)
ogrinfo -so
https://raw.githubusercontent.com/nvkelso/natural-earth-vector/master/geojson/ne_10m_airports.geojson

# Not working whereas it's a GeoJSON

ogrinfo -so /vsicurl/
https://ahocevar.com/geoserver/wfs?request=GetFeature&service=WFS&version=1.1.0&outputFormat=application/json&typenames=usa:states
