Scala 将未经验证的请求发送到其他操作路由

我在所有请求中实现一个全局过滤器，以识别发出请求的用户是否经过身份验证，如果没有，则将其发送到登录屏幕

我的全局对象扩展使用身份验证筛选器的WithFilters类：

object Global extends WithFilters(AuthenticationFilter()) { }

class AuthenticationFilter  extends Filter {
  def apply(next: (RequestHeader) => Future[Result])(request: RequestHeader): Future[Result] = {
    println("this is the request that will be filtered: " + request)
    if (!authenticated) 
      // How do i send the request to the login Action?
    else 
      next(request)
  }
}

object AuthenticationFilter {
  def apply(actionNames: String*) = new AuthenticationFilter()
}

我的身份验证筛选器：

object Global extends WithFilters(AuthenticationFilter()) { }

class AuthenticationFilter  extends Filter {
  def apply(next: (RequestHeader) => Future[Result])(request: RequestHeader): Future[Result] = {
    println("this is the request that will be filtered: " + request)
    if (!authenticated) 
      // How do i send the request to the login Action?
    else 
      next(request)
  }
}

object AuthenticationFilter {
  def apply(actionNames: String*) = new AuthenticationFilter()
}

我的问题是如何将未经身份验证的用户发送到登录操作/路由？

为安全路由创建特征。在这种情况下，当未经验证的请求传入时，请重定向它们：

trait Secured {

/**    
 * Retrieve the connected user name from the request header.  
 */   
private def username(request: RequestHeader) = request.session.get("username")

/**    
 * Redirect to login if the user in not authorized.    
 */
private def onUnauthorized(request: RequestHeader) = Results.Redirect(routes.Application.login)


/**    
 * Action for authenticated users.    
 */   
def IsAuthenticated(f: => String => Request[AnyContent] => Result) = Security.Authenticated(username, onUnauthorized) { user =>
  Action(request => f(user)(request))   
}


}

现在定义您想要保护的任何控制器以扩展该特性，未经验证的请求将被发送出去：

object Index extends Controller with Secured

问题是，我不想为特定的控制器或操作创建身份验证，我希望为每个请求检查身份验证。我不认为您能够在全局对象上执行此操作，因为至少有一个请求（登录页面）必须未经身份验证。让我们假设此操作有效。我该如何将请求转发到登录操作我想您应该在全局对象中放一行：

private def onUnauthorized（请求：RequestHeader）=Results.Redirect（routes.Application.Login）

如果您使用Spring，这将非常容易。只是一个想法
