How to parse JSON

nGrinder 3.1.1 contains json.jar, one of most famous Json parser(provided from www.json.org). You can easily parse json string with this library.
You can use this like the following.

JYTHON

from org.json import JSONObject

message = """
{
  "glossary": {
     "title": "example glossary",
        "GlossDiv": {
           "title": "S",
           "GlossList": {
              "GlossEntry": {
                 "ID": "SGML",
                 "SortAs": "SGML",
                 "GlossTerm": "Standard Generalized Markup Language",
                 "Acronym": "SGML",
                 "Abbrev": "ISO 8879:1986",
                 "GlossDef": {
                    "para": "A meta-markup language, used to create markup languages such as DocBook."
                 },
                 "GlossSee": "markup"
            }
         }
      }
  }
}
"""

json = JSONObject(message)
grinder.logger.info(json.get("glossary").getString("title"))

GROOVY

For groovy you can use JsonSlurper instead.

import groovy.json.JsonSlurper


....
def message = """
{
  "glossary": {
     "title": "example glossary",
        "GlossDiv": {
           "title": "S",
           "GlossList": {
              "GlossEntry": {
                 "ID": "SGML",
                 "SortAs": "SGML",
                 "GlossTerm": "Standard Generalized Markup Language",
                 "Acronym": "SGML",
                 "Abbrev": "ISO 8879:1986",
                 "GlossDef": {
                    "para": "A meta-markup language, used to create markup languages such as DocBook."
                 },
                 "GlossSee": "markup"
            }
         }
      }
  }
}"""
def jsonMsg = new JsonSlurper().parseText(message)
grinder.logger.info(jsonMsg.glossary.title)
