我正在使用play 2.1.1，并且在遍历数组时遇到问题。我读过某个地方，您可以为List
[Object]创建读取，但是每次尝试执行此操作时，都会收到一条错误消息"No unapply function found"：

implicit val userListReads: Reads[List[FBUser]] = Json.reads[List[FBUser]]". The issue is " = Json.reads[List[FBUser]]

我无所适从。任何帮助将不胜感激。

def linkUsers() = Action { implicit request =>
  val json = Json.parse("{\"data\": [{\"name\": \"Me Lazyan\",\"id\": \"1182\"},{\"name\": \"Chales Dselle\",\"id\": \"10115\"},{\"name\": \"Be My\",\"id\": \"10275\"},{\"name\": \"De Rwani\", \"id\": \"11189\"},{\"name\": \"Phoe Johon\", \"id\": \"11372\"}]}")

  val peoples = json.validate[List[FBUser]].get
  peoples.foreach(println)

  Ok(json).withHeaders(CONTENT_TYPE -> "text/json")
}

case class FBUser(
  name: String,
  id: String 
)

object FBUser {
    /** Uses a Scala Macro to define the Reads function */
    implicit val userReads: Reads[FBUser] = Json.reads[FBUser]
    implicit val userListReads: Reads[List[FBUser]] = Json.reads[List[FBUser]]
}
