How to get a value from a JSON (string) in Groovy

Question

I have been struggling to figure out how to get a parameter out of a JSON string in Groovy.

I have a string similar to:

'{"id":"12345678","name":"Sharon","email":"sharon\u0040example.com"}'

and am trying to extract the email address.

I can of course use regex, or other substring methods, but I'm sure there is a cleaner way.

Answer 1

Use JsonSlurper.

import groovy.json.JsonSlurper

def str = '{"id":"12345678","name":"Sharon","email":"sharon\u0040example.com"}'
def slurper = new JsonSlurper().parseText(str)

assert slurper.email == 'sharon@example.com'
assert slurper.name  == 'Sharon'
