JSONPath Expression to assert a list contains a specific element

I'm looking for an expression which checks if an element with id=123 is contained in a json-list. 

 

[
      {
      "id": "123"
      }
   },
      {
      "id": "456"
      }
   }
]

 Given the above list, I could use this JSONPath Expression: $[0].id but unfortunately, I can't guarantee that the element is always at index 0. Sometimes it would be $[1].id.

I tried with $[*].id but this extracts [[id1,id2]].

 

So basically, I'm looking for something like "is 123 equals to $[0].id OR $[1].id" or if that's not possible something like "does $[*].id contains an element "123". 

 

I'm using ReadyApi 1.4.1.

    I think you're looking for something like this:

    $[?(@.id == 123)].id

    Not very good at Json path.

    But below script assertion should do the job[using the assumed json array]

     

     

    import net.sf.json.groovy.JsonSlurper

    def jsonText = '''{
  "cars": [
    {
      "name" : "Jetta",
      "madeBy" : "Volkswagen"
    },
    {
      "name" : "Polo GT",
      "madeBy" : "Volkswagen"
    },
    {
      "name" : "i30",
      "madeBy" : "Hyundai"
    }
  ]
}'''
def jsonSlurper = new JsonSlurper()
def cars = jsonSlurper.parseText(jsonText).cars
def expectedName = 'Jetta' // You may use test case propperty here if you wish
def expectedValueExists=false
if (cars) {
    cars.each{if (it.name==expectedName) {expectedValueExists=true} }
}
if (expectedValueExists) { log.info "Expected car ${expectedName} exists"}
assert expectedValueExists, "Expected car name does not exists"

     

    Hope this is helpful
