Groovy. How can I get json elements in array

Question

there is such a JSON: https://restcountries.com/v3.1/all I just want to have a choice "translations" -> "ita" -> "common"

HTTPBuilder getHttpBuilder() {
    new HTTPBuilder('https://restcountries.com/')
}

def http = httpBuilder.request(Method.GET, ContentType.JSON){
    uri.path = 'v3.1/all'
    uri.query = [fields: 'translations,ita,common']
    response.success = { resp, json ->
        log.error(json.toString()) //string
        log.error(JsonOutput.toJson(json).br) //json
        log.error(JsonOutput.prettyPrint(JsonOutput.toJson(json))) //formated json
    }
}

but I always get either a general view or nothing of what is needed Help me to understand! Thank you!

Found this solution for me. Maybe someone else will stumble upon it too.

import groovy.json.JsonOutput
import groovyx.net.http.ContentType
import groovyx.net.http.HTTPBuilder
import groovyx.net.http.Method
import groovy.json.JsonSlurper

HTTPBuilder getHttpBuilder() {
    new HTTPBuilder('https://restcountries.com/')
}

def http = httpBuilder.request(Method.GET, ContentType.JSON){
    uri.path = 'v3.1/all'    
}

def tempJson = JsonOutput.toJson(http)
def resultParseJson = parseJsonText(tempJson)
def needResult = resultParseJson.translations.ita.common

def parseJsonText(String textJson){
    def jsonSlurper = new JsonSlurper()
    return jsonSlurper.parseText(textJson)
}

needResult - what I need. Perhaps someone will have a more beautiful or correct solution - I will be grateful. But so far this result is satisfactory.
