Accesing only key names of json using jsonPath

I have a simple question, say I have the following json

{
   "ALPHA":[
      ....
   ],
   "BETA":[
     ....
   ],
   "GAMMA":[
     .....
   ]
}

how do I access the subroot elements, I mean just the names: "ALPHA","BETA","GAMMA" using jsonPath? Be aware that I mean their names not their array!!!

I tried jsonPath("$[*]", ...) but it doesn't work, any sugesstions?

Solution

  • Thanks a lot @Raymond Choi, it should also work.

    But based on your answer, that I should use the function keys(), I search a lit bit more and I found that jsonPath indeed has his own function.

    So the solution to my question is simple:

    jsonPath("$.keys())
