Groovy Json parsing

Question

Hi i am bit new and need help to parse a hash, for example data: in current example,i want to loop through all keys TEST-A,TEST-B,TEST-C and change their value (app-id), for now using jsonslurper i can parse and edit value per key like this:

parsed.'TEST-A'[0].app_id = a

but what i want is to read keys and assign values (these value i will be reading as String)

---

import groovy.json.*
data = '''
{
    "TEST-A":   [{ "app_id":"aaa" }],
    "TEST-B":   [{ "app_id":"bbb" }],
    "TEST-C":   [{ "app_id":"ccc" }]
}'''

def parsed = new JsonSlurper().parseText(data)
String a= 'test';
parsed.'TEST-A'[0].app_id = a
def result = JsonOutput.toJson(parsed)
println "result: $result"

import groovy.json.*
data = '''
{
    "TEST-A":   [{ "app_id":"aaa" }],
    "TEST-B":   [{ "app_id":"bbb" }],
    "TEST-C":   [{ "app_id":"ccc" }]
}'''

def parsed = new JsonSlurper().parseText(data)
def a = 665
parsed.each{k,v-> 
  if(k in ['TEST-A','TEST-B','TEST-C']) v[0].app_id = a
}

println new JsonBuilder(parsed).toPrettyString()

output:

{
    "TEST-A": [
        {
            "app_id": 665
        }
    ],
    "TEST-B": [
        {
            "app_id": 665
        }
    ],
    "TEST-C": [
        {
            "app_id": 665
        }
    ]
}
