I would add that you should use {{velocity wiki="false"}} as otherwise
your JSON is going to be parsed as wiki syntax.
Hi everybody,
I am new at XWiki and I would like to know if it's possible to build a JSON
object in a velocity script and get later this JSON via the REST API.
This is my script :
{{velocity}}
#if($xcontext.action == 'get' && "$!{request.outputSyntax}" ==
'plain')
$response.setContentType('application/json')
#end
#set($hql = "")
#set($results = $xwiki.searchDocuments($hql))
#set($json= "[" )
#set($started = false)
#foreach($item in $results)
#set($itemdoc = $xwiki.getDocument($item))
#if($started)
#set($pointvirgule=",")
#set($json = "${json} ${pointvirgule}" )
#else
#set($started = true)
#end
#set($suite="{ ""name"" :
""${itemdoc.fullName}""}")
#set($json= "${json} ${suite}")
#end
#set($fin="]")
#set($json= "${json} ${fin}")
$json
It is advisable to build the JSON in memory using objects like maps,
arrays, etc. and then serialize the 'root' object using the JSON
Velocity tool
http://extensions.xwiki.org/xwiki/bin/view/Extension/Velocity+Module#HJSONT…
. One of the advantages with this approach is that you don't have to
care about escaping JSON values (in your code above any of the strings
you put in the JSON can contain special characters that would break
the JSON).
And you don't need REST to access the generated JSON. Just use the
page URL (/xwiki/bin/get/Space/Page?outputSyntax=plain).
Hope this helps,
Marius

{{/velocity}}
I thought my JSON would be in the content of my page but when I try to get
this content with REST API I only have the velocity script in hard.
Someone could help me ?
Thanks in advance for your answers.
