Hi,
I've attached a quick'n dirty solution (against master). When applied to
mapogroutput.c you can set a JSONP formatoption to the callback name:
OUTPUTFORMAT
NAME 'geojson'
DRIVER 'OGR/GEOJSON'
MIMETYPE 'application/json; subtype=geojson; charset=utf-8'
FORMATOPTION 'STORAGE=stream'
FORMATOPTION 'FORM=simple'
FORMATOPTION 'LCO:COORDINATE_PRECISION=5'
FORMATOPTION 'JSONP=%callback%'
END
This needs of course a WEB.VALIDATION:
WEB
...
VALIDATION
callback '.*'
END
END
Would be great if you can test if this works (looks good to me). The Devs might
have a look if this could be integrated into master until OGR has an
appropriate layer creation option (solution described by Even).
Greetings

Betreff: Re: [mapserver-users] Setting up a JSONP service
Hello,
first of all: Thank you for your support!
Sorry for the late reply but I unfortunately was ill.
@ Steve:
I read about templating but also read that it is slower?
I do not have a lot of experience in writing templates. Would you mind
sharing a JSONP template?
@ Even: Thank you for your thoughts. Who would implement that change
though? I'm afraid I can't.
@ Jeff: I followed those links but I only found threads referring to
GeoServer or that were not related to my question. The GDAL page I did
study and that's how I managed to set up the GeoJSON service but thats
not the same unfortunately as it conflicts with the same origin policy.
Best
Lars

You can also use MapServer templates to accomplish this. It's a little
more work since you have to write the template but it's quite flexible
then. Usually I write the template to produce JSON and then use a simple
wrapper template to produce JSONP. For example, jsonp.js looks like
(callback is passed in):
// MapServer Template
[callback](
[include src=templates/json.js]
)
Output formats look like:
OUTPUTFORMAT
NAME 'JSON'
DRIVER 'TEMPLATE'
MIMETYPE 'application/json;'
FORMATOPTION 'FILE=templates/json.js'
FORMATOPTION 'ATTACHMENT=service.json'
END
OUTPUTFORMAT
NAME 'JSONP'
DRIVER 'TEMPLATE'
MIMETYPE 'application/json;'
FORMATOPTION 'FILE=templates/jsonp.js'
FORMATOPTION 'ATTACHMENT=service.json'
END

Subject: [mapserver-users] Setting up a JSONP service
Dear List,
I have a WFS service running under MapServer that I would like to
operate as JSONP service. I managed to set GEOJSON as output format but I
get Cross-Origin-Request Blocked if I try to call it with a Javascript
client (using Leaflet L.layerJSON.
The question is: Is it possible to set up a JSONP service from Mapserver
and if yes, how? My current mapfile looks like this (relevant parts):
# in WEB - METADATA
wfs_getfeature_formatlist geojson,csv,ogrgml
OUTPUTFORMAT
NAME geojson
DRIVER OGR/GEOJSON
MIMETYPE application/json; subtype=geojson; charset=utf-8
FORMATOPTION STORAGE=stream
FORMATOPTION FORM=SIMPLE
FORMATOPTION LCO:COORDINATE_PRECISION=5
END
If this would already be a correct JSONP service, I have to look on the
Leaflet side for the error...
Thanks for your help.
Cheers
Lars
