Validate that the values of List exist in Json Object and return True or False

Question

I am trying to validate if props:List<String> values exist with message:String and return if the value is true or false.

fun main() {

val message = """
            {
                "id": "xxxxx",
                "action": "Do",
                "resource": "Login",
                "type": "ok",
                "data": {
                "username": "+521234567890",
                "password": "12345"
            }
            }"""
val words = listOf("dog","flower","cat")
messageValidator(message,words)}


fun validator(message:String, props:List<String>):Boolean{

val words = props.iterator()
val messagejson = Json.parseJson(message).jsonObject


for(x in words){
    //println(x)
    //val dataWords = messagejson.containsKey(x)
    val dataWords = messagejson.containsKey(x)
    //println(dataWords)
    if (dataWords == true){
        println(x)
        return true
    }
    if (!dataWords){
        println(x)
        return false
    }
}
return false }

I really don't know how to continue validating

Not sure if this is what you were looking for, But this goes over every object in words, And if the message doesn't contain x it returns false, otherwise true.

for(x in words){
    if(!messagejson.containsKey(x))
        return false

}
return true
}

Instead of using a loop, you could also write:

fun validator(message: String, props: List<String>) =
        props.any { message.contains(it) }

Wow! this line of code if it is interesting, I found several examples similar to yours, as I just started with kotlin because little by little I will know how to reduce lines of code. Also thanks for the help. – John Snow Jun 17 '20 at 22:44
