Question

我正在尝试做与this类似的事情。 ContextRequest和ContextAction。我有一个来自securedRequest的{{1}}，我想撰写一个Silhouette来阅读我设置的Action。

区别在于我从剪影cookie扩展了User

Identity

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

我无法获得trait DefaultEnv extends Env { type I = User type A = CookieAuthenticator }，因为

（请注意com.mohiva.play.silhouette.api.Identity与模型不匹配。用户：类包实体中的用户是包api中特征标识的子类，但是方法参数类型必须完全匹配。）

我知道我可能缺少包装纸。

Answer 1

尝试提供绑定到Env的上下文，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
}

Answer 2

我在请求请求中添加了一些功能，这些功能应该执行相同的操作https://github.com/mohiva/play-silhouette-seed/pull/118
