類型Iteratee [Array [Byte]，StatusHeader]的表達式與Play scala中期望的類型Accumulater [Byte，Result]不一致？

class AuthorizedFilter extends EssentialFilter { 

    private def authorizationRequired(request: RequestHeader) = { 
    val clientId = request.headers.get("clientId"); 
    val id = "74f6df0452"; //to match with clientID.Block remaining request 
    clientId match { 
     case Some(id) => 
     true; 
     case _ => 
     false; 
    } 

    } 

    def apply(next: EssentialAction):EssentialAction = new EssentialAction { 
    def apply(request: RequestHeader) = { 
     println("result...",request.headers.get("clientId")); 

     if(!authorizationRequired(request)) { 
     *Iteratee.ignore[Array[Byte]].map(_ => Results.forbidden())* 
     } 
     else { 
     println("YOU are authorized!!") 
     next(request) 
     } 
     } 
    } 
}

上面的過濾器被添加來阻止clientID不匹配的所有請求。我在Iteratee.ignore [Array [Byte]]。map（_ => Results.forbidden（））中收到了錯誤消息。類型Iteratee [Array [Byte]，StatusHeader]的表達式與Play scala中期望的類型Accumulater [Byte，Result]不一致？
