使用簡單控制器播放框架2.5錯誤

Question

嘗試使用簡單控制器播放框架2.5時遇到的錯誤消息令人困惑。下面是我在做什麼：上面寫着

object UserController extends Controller { 

    def login = Action.async(BodyParsers.parse.json) { request => 
    val body = request.body.validate[UserLogin] 
    // call the userService and validate the credentials 
    body.fold(
     errors => { 
     BadRequest(Json.obj("status" -> "error", "message" -> JsError.toFlatJson(errors))) 
     }, // error here 
     message => { 
     Ok("") 
     } // error here 
    ) 
    } 
} 

我收到錯誤消息：

"Expression of type Result does not conform to expected type _X"

我需要包裝該呼叫並在未來！所以這裏是如何做到這一點！

object UserController extends Controller { 

    def login = Action.async(BodyParsers.parse.json) { request => 
    val body = request.body.validate[UserLogin] 
    // call the userService and validate the credentials 
    body.fold(
     errors => { 
     Future.successful { BadRequest(Json.obj("status" -> "error", "message" -> JsError.toFlatJson(errors))) } 
     }, // error here 
     message => { 
     Future.successful { Ok("") } 
     } // error here 
    ) 
    } 
}
