Convert JsDefined to String

Question

I use play json library to process json objects in Scala. In order to get a field id from the json object, I run this code:

val id = json \ "id"

Then I want to convert id into a String. I tried id.get.toString but instead of doi:10.1186-s13612-016-0045-3 I got JsDefined("doi:10.1186-s13612-016-0045-3")

How to convert it into a String?

Answer 1

Slightly shorter:

(json \ "id").as[String]

Answer 2

Try

(json \ "id").as[JsString].value
