Scala - Couldn't remove double quotes for "{}" braces while building Json
import scala.util.Random
import math.Ordered.orderingToOrdered
import math.Ordering.Implicits.infixOrderingOps
import play.api.libs.json._
import play.api.libs.json.Writes
import play.api.libs.json.Json.JsValueWrapper
val data1 = (1 to 2)
.map {r => Json.toJson(Map(
"name" -> Json.toJson(s"Perftest${Random.alphanumeric.take(6).mkString}"),
"domainId"->Json.toJson("343RDFDGF4RGGFG"),
"value" ->Json.toJson("{}")))}
val data2 = Json.toJson(data1)
println(data2)
Result : [{"name":"PerftestpXI1ID","domainId":"343RDFDGF4RGGFG","value":"{}"},{"name":"PerftestHoZSQR","domainId":"343RDFDGF4RGGFG","value":"{}"}]
Expected : "value":{}
[{"name":"PerftestpXI1ID","domainId":"343RDFDGF4RGGFG","value":{}},{"name":"PerftestHoZSQR","domainId":"343RDFDGF4RGGFG","value":{}}]
Please suggest a solution
CodePudding user response:
You are giving it a String
so it is creating a string in JSON. What you actually want is an empty dictionary, which is a Map
in Scala:
val data1 = (1 to 2)
.map {r => Json.toJson(Map(
"name" -> Json.toJson(s"Perftest${Random.alphanumeric.take(6).mkString}"),
"domainId"->Json.toJson("343RDFDGF4RGGFG"),
"value" ->Json.toJson(Map.empty[String, String])))}
More generally you should create a case class
for the data and create a custom Writes
implementation for that class so that you don't have to call Json.toJson
on every value.
