scala - 播放 2.6 剪影组成 SecuredAction

Question

我正在尝试做一些与此非常相似的事情。ContextRequest和ContextAction。我有一个securedRequest来自Silhouette，我想撰写一个我设置的Action阅读。cookie

不同的是我扩展了Userfrom SilhouetteIdentity

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
}

我无法得到User因为

（注意 com.mohiva.play.silhouette.api.Identity 不匹配 models.User：包实体中的类 User 是包 api 中 trait Identity 的子类，但方法参数类型必须完全匹配。）

我知道我可能缺少一个包装器。

尝试为您的 提供一个上下文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
}
