如何在Play 2 + Scala中拦截所有控制器请求? [英] How do I intercept all controller requests in Play 2 + Scala?

问题描述

在Play 2的Java版本中，有 GlobalSettings.onRequest ，可以用来拦截所有传入控制器的请求.但是在 Scala等效版本中，没有onRequest处理程序.

In the Java flavor of Play 2, there is GlobalSettings.onRequest, which can be used to intercept all incoming requests to controllers. But in the Scala equivalent, there is no onRequest handler.

我怀疑这是因为Scala中不需要Java所需的Action委派逻辑，但这很烦人，因为我想在每个传入的控制器请求上运行一些代码.

I suspect this is because the Action delegation logic needed in Java isn't required in Scala, but it's rather annoying because I want to run some code on every incoming controller request.

有人知道如何在Scala + Play 2应用程序中拦截所有控制器请求吗?

Does anyone know how to intercept all controller requests in a Scala + Play 2 app?
