發送未經身份驗證的請求到不同的操作路由

Question

我正在實施跨所有請求的全局篩選器，以確定發出請求的用戶是否已通過身份驗證，以及是否將它們發送到登錄屏幕。

我延長其使用的身份驗證篩選器的WithFilters類全局對象：

object Global extends WithFilters(AuthenticationFilter()) { } 

我的身份驗證篩選器：

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() 
} 

我的問題是我怎麼去發送一個未認證用戶的登錄行動/路線？

Answer 1

爲安全路線創建一個特徵。在這種性質時，未認證的請求進來他們重定向：

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)) 
} 


} 

現在定義要固定，以便擴展特性的任何控制器和身份認證的請求會被送走：

object Index extends Controller with Secured
