如何在Scala中屏蔽JSON测试中的密码等敏感字段？

import play.api.libs.json._

case class User(id: Int, name: String, email: String, password: String)

object User {
  implicit val format: Format[User] = new Format[User] {
    def writes(user: User): JsValue = {
      val json = Json.obj(
        "id" -> user.id,
        "name" -> user.name,
        "email" -> user.email
      )
      if (shouldHidePassword) {
        json ++ Json.obj("password" -> "***")
      } else {
        json ++ Json.obj("password" -> user.password)
      }
    }
    
    def reads(json: JsValue): JsResult[User] = {
      val id = (json \ "id").as[Int]
      val name = (json \ "name").as[String]
      val email = (json \ "email").as[String]
      val password = (json \ "password").as[String]
      JsSuccess(User(id, name, email, password))
    }
    
    private def shouldHidePassword: Boolean = {
      // Add your logic here to determine whether to hide the password field
      // For example, you can check the environment or configuration settings
      true
    }
  }
}

// Usage example
val user = User(1, "John Doe", "john@example.com", "secretpassword")
val json = Json.toJson(user)
println(json)
