在Play2.0中以编程方式添加路线 [英] Programmatically adding a route in Play2.0

问题描述

在游戏1.2.X中我们可以做到

In play 1.2.X we could do

Router.addRoute("GET", "/somePath", "controller.methodName");

我正在编写一个添加路由"的模块，该路由将由模块中的控制器处理.这是一个OAuth处理程序，希望使用户能够轻松处理OAuth握手等.

I'm writing a module that adds a "route" that will be handled by a controller in the module. It's a OAuth handler and want to make it easy for users to not have to deal with the OAuth handshake etc.

如何在Play 2.0中做到这一点?

How can I do this in Play 2.0?

推荐答案

您不能以编程方式将其添加到Routes对象，但是可以拦截Web请求并通过覆盖GlobalSettings.onRouteRequest自己处理它们.例如:

You can't add programmatically to the Routes object, but you can intercept web requests and handle them yourself by overriding GlobalSettings.onRouteRequest. For example:

override def onRouteRequest(request: RequestHeader): Option[Handler] = {
  //do our own path matching first - otherwise pass it onto play.
  request.path match {
    case "/injectedRoute" => Some(controllers.Application.customRoute)
    case _ => Play.maybeApplication.flatMap(_.routes.flatMap {
      router =>
      router.handlerFor(request)
    })
  }
}

我不知道这是否是推荐的方法，但是它对我有用.这是github上的示例: https://github.com/edeustace/play-injected-routes -示例

I've no idea if this is the recommended approach, but it works for me. Here's a sample on github: https://github.com/edeustace/play-injected-routes-example
