Scala 使用剪影4.0播放2.5-凭证提供程序

我正试图用Play2.5编写一个示例应用程序，使用剪影4.0进行用户/密码身份验证

源代码可从以下网址获得：

我无法在环境对象中设置requestProvider

Environment[JWTEnv](
  identityService,
  authenticatorService,
  Seq(),
  eventBus
)

由于我无法找到解决方案，我正在我的所有控制器类中注入凭据提供程序

    class MyController @Inject() (val messagesApi: MessagesApi,val silhouette: Silhouette[JWTEnv],
  authInfoRepository: AuthInfoRepository,
  credentialsProvider: CredentialsProvider)
    extends Controller {
          def authenticate = Action.async(BodyParsers.parse.json) { implicit request =>
        credentialsProvider.authenticate(Credentials(data.email, data.password)).flatMap { loginInfo => ..}    
         //   silhouette.env.requestProviders.foreach { x => println("====" + x.id) }  --- I am hoping to get credential provider from silhouette object

        ...
        ...
        }
    }

我的Module.scala如下所示-

你能帮帮我吗

谢谢

请求提供程序在Module.scala中设置，但它们设置为空序列：

@Provides
def provideEnvironment(
  identityService: IdentityService[User],
  authenticatorService: AuthenticatorService[JWTAuthenticator],
  eventBus: EventBus): Environment[JWTEnv] = {

  Environment[JWTEnv](
    identityService,
    authenticatorService,
    Seq(),                 // Here the request providers are set
    eventBus
  )
}

---

Ps：请记住，

foreach

将始终“不返回”，因为它的类型是

unit

您在这里混合了两种不同的东西。凭据提供程序不是请求提供程序。请求提供程序是一种特殊类型的提供程序，可以直接连接到请求中。有关详细说明，请参阅。剪影提供了一个请求提供者的实现

---

凭据提供程序应直接注入控制器中。

谢谢Moritz。我后来才弄明白。我已经在控制器中显式地注入了val-credentialsProvider:credentialsProvider。我现在可以使用凭据提供程序。不确定如何在环境中设置。什么是代码而不是Seq（）。任何想法。Thanks@Moritz-您能帮我做一些类似的事情，但编译时注入除外。SO问题创建于感谢信息。我想，我需要更彻底地阅读请求提供者。
