JSONBuilder in Groovy adds wrong quotation marks - json

Question

I'm trying to read a json file, edit some parts of it and then parse it back to a json file. The goal is to change the value of a confluence page. I'm using the groovy code in a Jenkins pipeline. Here it is:
def changeValue(){
def json_map = readJSON file: '/tmp/updater.json'
def body_content = '{"storage":{"value":'
body_content += '"<h1>test</h1>"'
body_content += ',"representation":"storage"}}'
json_map.body = body_content
json_as_string = new JsonBuilder(json_map).toPrettyString().replaceAll("\\\\", "") // It also adds unneccesary escapes
print json_as_string
}
This is the contents of the updater.json:
{
"id":"redacted",
"type":"page",
"title":"redacted",
"space":{"key":"redacted"},
"body":{"storage":{"value":"<h1>wrong</h1>","representation":"storage"}},
"version":{
"number":6
}
}
That is what I get:
{
"id": "redacted",
"type": "page",
"title": "redacted",
"space": {
"key": "redacted"
},
"body": "{"storage":{"value":"<h1>test</h1>","representation":"storage"}}",
"version": {
"number": 6
}
}
As you can see, it added quotation marks around the block of the body. How can I get rid of them?

Answer 1

The result is as expected, you update the body with a new String.
If you want to update only the value use this based on this answer
import groovy.json.JsonBuilder
import groovy.json.JsonSlurper
def jsn = """
{
"id":"redacted",
"type":"page",
"title":"redacted",
"space":{"key":"redacted"},
"body":{"storage":{"value":"<h1>wrong</h1>","representation":"storage"}},
"version":{
"number":6
}
}"""
def slp= new JsonSlurper().parseText(jsn)
bld.content.body.storage.value = '<h1>test</h1>'
println(bld.toPrettyString())
result
{
"id": "redacted",
"type": "page",
"title": "redacted",
"space": {
"key": "redacted"
},
"body": {
"storage": {
"value": "<h1>test</h1>",
"representation": "storage"
}
},
"version": {
"number": 6
}
}
