Question

我正在尝试使用Silhouette 4.0编写一个使用Play 2.5的示例应用程序进行用户/密码验证。

源代码：https://github.com/pariksheet/dribble

我被困在环境对象

中设置requestProvider

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

由于我无法找到解决方案，因此我在所有控制器类中注入了Credential Provider。

    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 -

你能帮帮我吗？

你在这里混合了两件不同的东西。凭证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。详细说明可在documentation中找到。 Silhouette提供Basic Authentication provider，它是请求提供者的实现。

凭据提供程序应直接注入您的控制器，如seed template中所实现的那样。

使用Silhouette 4.0播放2.5 - 凭据提供者
