玩2个反向路由，从控制器方法获取路由 [英] Play 2 reverse routing, get route from controller method

问题描述

使用 Play 2.2.3 框架，因为我的路由文件中有这样的路由:

Using the Play 2.2.3 framework, given I have a route like this one in my routes file :

GET         /event                                 controllers.Event.events

如何以编程方式获取/event"，知道我试图达到的方法，在这种情况下是 'controllers.Authentication.authenticate' ?

How can I programatically get the "/event" knowing the method I am trying to reach, in this case 'controllers.Authentication.authenticate' ?

我需要它用于测试目的，因为我希望有更好的测试，而不是等待路由本身，而是等待真正调用的控制器方法.因此，也许还有另一种解决方案，而不是像我现在那样获取路线并以这种方式进行测试:

I need it for test purpose, because I would like to have better test waiting not for the route itself but for the controllers method really called. So maybe there is another solution than getting the route and test it this way like I do for now :

//Login with good password and login
    val Some(loginResult) = route(FakeRequest(POST, "/login").withFormUrlEncodedBody(
      ("email", email)
      , ("password", password)))
    status(loginResult)(10.seconds)     mustBe 303
    redirectLocation(loginResult).get mustBe "/event"

推荐答案

你这样构造反向路由:

[full package name].routes.[controller].[method]

在你的例子中:

 controllers.routes.Authentication.authenticate
 controllers.routes.Events.events

但是如果你像 controllers.auth 和 controllers.content 一样把你的包分开，那么它们会是:

But say you broke your packages out like controllers.auth and controllers.content, then they would be:

 controllers.auth.routes.Authentication.authenticate
 controllers.content.routes.Events.events

反向路由返回一个 Call，其中包含一个 HTTP 方法和 URI.在您的测试中，您可以使用 Call 构造一个 FakeRequest:

The reverse routes return a Call, which contains an HTTP method and URI. In your tests you can construct a FakeRequest with a Call:

 FakeRequest(controllers.routes.Authentication.authenticate)

你也可以用它来测试重定向 URI:

And you can also use it to test the redirect URI:

 val call: Call = controllers.routes.Events.events 
 redirectLocation(loginResult) must beSome(call.url)
