I'd like to be able to generate pure JSON from a wiki page, to use in other pages via
AJAX. To that end I created a page with the following content:
{{velocity wiki="false"}}
$response.setContentType('application/json')
{
"greeting" : "Hello",
"location": "World"
}
{{/velocity}}
Calling this via /xwiki/bin/get/Sandbox/JsonTest I get the following code:
<p><br/>{<br/>"greeting" :
"Hello",<br/>"location":
"World"<br/>}</p>
I get the same via /xwiki/bin/view/AlertDB/JsonTest?xpage=plain.
If I remove the $response.setContentType('application/json')

Inded, I would have imagine also that xpage=plain would have worked but it doesn’t. You
have to use outputsyntax.
For example: http://playground.xwiki.org/xwiki/bin/get/Main/VMA?outputSyntax=plain
Note: You can go on a page with a livetable and check with Chrome dev tools or Firebug the
requests done and you’ll see it uses that.
Thanks

Thanks so much for that. It did indeed work :-)
So 'view' with xpage=plain&outputSyntax=plain or just 'get' with
outputSyntax=plain does the job.
Now I know what to look for, for posterity I've put this information into
http://extensions.xwiki.org/xwiki/bin/view/Extension/Output+JSON
FWIW I'd have rather put the license as something like "public domain", but
the closest ("Do What The F*** You Want..") seemed unnecessarily vulgar. Does
such language really have a place on your website?
Thanks,
Bryn

I agree it looks vulgar. However this is a real license,

Instead of printing the JSON directly I recommend using the $jsontool
(see http://extensions.xwiki.org/xwiki/bin/view/Extension/Velocity+Module#HVeloc…
). The advantage is that you don't have to care about escaping JSON
(property) values.
$jsontool.serialize({
"greeting" : $someObject.greeting,
"location": $someOtherObject.location
})
Hope this helps,
Marius
