Play 2.6 Silhouette compose SecuredAction

Question

我正在嘗試做一些與此非常相似的事情。 ContextRequest和ContextAction 。 我有一個來自Silhouette的securedRequest ，我想securedRequest一個Action讀取我設置的cookie 。

不同的是我從Silhouette Identity擴展了User

DataSourceRequest

class DataSourceRequest[DefaultEnv, B](
  val dataSource: Option[String],
  val securedRequest: SecuredRequest[DefaultEnv, B]
) extends WrappedRequest[B](securedRequest.request) {
  def user: User = securedRequest.identity
  def requestV: Request[B] = securedRequest.request
}

DataSourceAction

class DataSourceAction @Inject()
  (val parser: BodyParsers.Default)(implicit val executionContext: ExecutionContext)
  extends ActionRefiner[({ type R[B] = SecuredRequest[DefaultEnv, B] })#R, ({ type R[B] = DataSourceRequest[DefaultEnv, B] })#R] {

  override protected def refine[A](securedRequest: SecuredRequest[DefaultEnv, A]) = Future.successful {
    try {
      Right(new DataSourceRequest[DefaultEnv, A](
        securedRequest.session.get("dataSource").getOrElse("dataSourceMissing"),
        securedRequest
      ))
    } catch {
      case _: Exception => Left(Results.NotFound)
    }
  }
}

DefaultEnv

trait DefaultEnv extends Env {
  type I = User
  type A = CookieAuthenticator
}

我無法獲得User因為

（注意com.mohiva.play.silhouette.api.Identity不匹配models.User：包實體中的類User是包api中trait Identity的子類，但方法參數類型必須完全匹配。）

我知道我可能缺少一個包裝器。

嘗試將上下文綁定到您的Env ，如下所示：

class DataSourceRequest[Env <: DefaultEnv, B](
  val dataSource: Option[String],
  val securedRequest: SecuredRequest[Env, B]
) extends WrappedRequest[B](securedRequest.request) {
  def user: User = securedRequest.identity
  def requestV: Request[B] = securedRequest.request
}

我在拉取請求中添加了一些功能，這些功能應該做同樣的事情https://github.com/mohiva/play-silhouette-seed/pull/118
