Behaviour and external API does not return correctly

serge calderara

Dear all,

I am trying to build a behaviour which convert a text field in a select list box by collecting data from an exteranal API.

For that I follow the samples provided in this link below :

Select List Conversions (adaptavist.com)

I have for that created a simple REST API call which collect VM information from Azure and which return the following sample data from POSTMAN

From my custom Rest endpoint, I need to return the *tags list items* in order to be visible into the Select List field of my behavior

The issue I met is that I do not know, or at least it is not so clear from sample on the way I should format the return response from the API in order that behavior gets the data

In my sample snipet code below, I need to return, as in the sample, a New JsonBuilder object based on my json return by the API but I could not get the correct syntax to replace in ???????? in order that my field slection contains items *com, aem, dispatcher* from tags element of my original return json above

Any idea ?

I am struggling this for a full week now and I am stuck, hoping you can help

regards

The select conversion method need the JSON in very specific format.

So you'll need to prepare a return object with that format.

Based on what you provided, I'm expecting the vmInfo object returned by httpBuilder.request to look something like this (as you would deeclarie it in groovy)

[
   name:'dummy', 
   location:"don't care", 
   tags:[
      app:'appname', 
      product:'aem', 
      type:'dispatcher']
]

So if I start with building a replacement variable with this data, I can use that to construct the output object

def vmInfo = [name:'dummy', location:"don't care", tags:[app:'appname', product:'aem', type:'dispatcher']]
//we're only interested in the tags ... I've opted to include both tag key and value sepearated by colon, but you can adjust that format
def tags = vmInfo.tags.collect{k,v-> "$k : $v"}

//normally, the query should come from your rest api with 
//def query = queryParams.getFirst("query") as String
// but I used this for testing
def query = 'prod'
//this is the object we need to return
def singleSelectRet = [
     items : tags.collect{tag -> 
        [
           value: tag,
           label: tag,
           html: tag.replaceAll(/(?i)$query/) { "<b>${it}</b>" }
        ]
     },
     total : tags.size(),
     footer : "Select a tag"
]
return Response.ok(new JsonBuilder(singleSelectRet).toString()).build()
