title: How to extract values from json in jmeter when the keys are unkown?
body: <p>I have a json response as,
  {
    'sadasd123242' : 'asdadada122dfsfs',
    'dadsadaskljk' : 'adasdasdasdsadds'
  }
  I want to extract the keys from the response in jmeter test using the JSON extractor. I am unable to do this as I do not know the keys in the response. How do I get the keys ?</p>
