Groovy - parse/ convert x-www-form-urlencoded to something like JSON

Question

this is my second try to explain a bit more precisely what I'm looking for ;-)

I set a webhook in Mailchimp that fires every time a new subscriber of an audience appears. Mailchimp sends a HTTP POST request to a Jira Sriptrunner REST endpoint.

The content type of this request is application/x-www-form-urlencoded.

Within the Jira endpoint I would like to read the request data. How can I do that?

The payload (raw body) I receive looks like this:

type=unsubscribe&fired_at=2020-05-26+07%3A04%3A42&data%5Baction%5D=unsub&data%5Breason%5D=manual&data%5Bid%5D=34f28a4516&data%5Bemail%5D=examlple%40bla.com&data%5Bemail_type%5D=html&data%5Bip_opt%5D=xx.xxx.xxx.198&data%5Bweb_id%5D=118321378&data%5Bmerges%5D%5BEMAIL%5D=example%40bla.com&data%5Bmerges%5D%5BFNAME%5D=Horst&data%5Bmerges%5D%5BLNAME%5D=Schlemmer&data%5Bmerges%5D%5BCOMPANY%5D=First&data%5Bmerges%5D%5BADDRESS%5D%5Baddr1%5D=XXX

Now I would like to parse the data of the raw body into a JSON or something similiar.

The result might look like this:

{
 "web_id": 123,
 "email": "example@bla.com",
 "company": "First",
 ...
 }

Meanwhile I searched around a little and found something like the node.js "querystring" module. It would be great if there is something similiar within Groovy or any other way to parse the data of application/x-www-form-urlencoded to json format.

Best regards and thanks in advance

def body = "type=unsubscribe&fired_at=2020-05-26+07%3A04%3A42&data%5Baction%5D=unsub&data%5Breason%5D=manual&data%5Bid%5D=34f28a4516&data%5Bemail%5D=examlple%40bla.com&data%5Bemail_type%5D=html&data%5Bip_opt%5D=xx.xxx.xxx.198&data%5Bweb_id%5D=118321378&data%5Bmerges%5D%5BEMAIL%5D=example%40bla.com&data%5Bmerges%5D%5BFNAME%5D=Horst&data%5Bmerges%5D%5BLNAME%5D=Schlemmer&data%5Bmerges%5D%5BCOMPANY%5D=First&data%5Bmerges%5D%5BADDRESS%5D%5Baddr1%5D=XXX"

def map = body.split('&').collectEntries{e->
    e.split('=').collect{ URLDecoder.decode(it, "UTF-8") }
}

assert map.'data[merges][EMAIL]'=='example@bla.com'
map.each{println it}

prints:

data[action]=unsub
