Format JSON data from custom REST Endpoint Edited

[Ian Balas]

Hi all,

I'm tasked with formatting the returned JSON Data that's returned from this custom REST Endpoint code that we're working with:

import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovy.json.JsonBuilder
import groovy.transform.BaseScript
import groovyx.net.http.ContentType
import groovyx.net.http.HTTPBuilder
import groovyx.net.http.Method

import javax.ws.rs.core.MultivaluedMap
import javax.ws.rs.core.Response
import groovy.xml.MarkupBuilder




@BaseScript CustomEndpointDelegate delegate2

CMRDisplay(httpMethod: "GET") { MultivaluedMap queryParams ->

    def query = queryParams.getFirst("query") as String

    def rt = [:]
    if (query) {

        String url = "https://test.service-now.com"
        String uriPath = "/api/now/table/u_jira_change_data"

        HTTPBuilder http = new HTTPBuilder(url)
        def output = http.request(Method.GET, ContentType.JSON) {
        uri.path = uriPath
        uri.query = [sysparm_query:"u_jira_ticket_number=$query", sysparm_fields:"u_change_record.number,u_change_record.short_description,u_change_record.state", sysparm_display_value: "true"]
        headers.'Authorization' = "Basic ${"svc-jira:buO\$qguQUgat5lNVF7GH\$3VMtjaR1o".bytes.encodeBase64().toString()}"

         response.failure = { resp, reader ->
                log.warn("Failed to query SNow API: " + reader.text)
             }
        }


        def cmrState = output["result"]*."u_change_record.state"
        def cmrNumber = output["result"]*."u_change_record.number"
        def cmrDesc = output["result"]*."u_change_record.short_description"

      rt = output 

    return Response.ok( new JsonBuilder(rt).toString()).build(); 
  }
}

For a certain issue in our instance, the output is converted to string and parsed to a multi-text field like so:

{"result":[{"u_change_record.number":"CHG0010042","u_change_record.state":"Draft","u_change_record.short_description":"test app req 5"},
{"u_change_record.number":"CHG0010061","u_change_record.state":"Draft","u_change_record.short_description":"test"},
{"u_change_record.number":"CHG0016010","u_change_record.state":"Draft","u_change_record.short_description":"Test Jira"},
{"u_change_record.number":"CHG0010057","u_change_record.state":"Draft","u_change_record.short_description":"tesst"}]}

Is there any way that I can format this output to resemble proper JSON structure?

Like below:

{
  "result": [
    {
      "u_change_record.number":"CHG0010042",
      "u_change_record.state":"Draft",
      "u_change_record.short_description":"test app req 5"
    },
    {
      "u_change_record.number":"CHG0010061",
      "u_change_record.state":"Draft",
      "u_change_record.short_description":"test"
    },
    {
      "u_change_record.number":"CHG0016010",
      "u_change_record.state":"Draft",
      "u_change_record.short_description":"Test Jira"
    },
    {
      "u_change_record.number":"CHG0010057",
      "u_change_record.state":"Draft",
      "u_change_record.short_description":"tesst"
    }
  ]
}

The first JSON output is perfectly valid for machine parsing

But if you want a pretty layout, you can output toPrettyString()

return Response.ok( new JsonBuilder(rt).toPrettyString()).build();

Ah, that was simple enough.

Thanks!
