从Play框架(Scala)中的play.api.mvc.Action [AnyContent]获取响应正文 [英] Get Response body from play.api.mvc.Action[AnyContent] in Play framework (Scala)

问题描述

我有以下Play(Scala)代码:

I have the following Play (Scala) code:

object Experiment extends Controller {

 //routes file directs /genki here
 def genki(name: String) = Action(pipeline(name))

 def pipeline(name: String) = {
   req:play.api.mvc.RequestHeader => {
      val template = views.html.genki(name)
      Experiment.Status(200).apply(template).as("text/html")
   }
 }

 def simple = Action {
   SimpleResult(
      header = ResponseHeader(200, Map(CONTENT_TYPE -> "text/plain")),
      body = Enumerator("Hello World!".getBytes())
   )
 }

}

这可以正常编译，并且可以正常工作.

This compiles fine and works as expected.

使用scala REPL如何显示实际的html?

Using the scala REPL how can I display the actual html?

我有:

 scala> val action = simple
 action: play.api.mvc.Action[play.api.mvc.AnyContent] = Action(parser=BodyParser(anyContent))    

我要表示的是，现在REPL中的值引用'action'是一个Action对象，类型受AnyContent约束(这是正确的说法吗?).

which I take to mean that now the value reference 'action' in the REPL is an Action object which is type-constrained for AnyContent (is that correct way to say it?).

我现在如何使用此操作来打印Http响应html内容?

how can I now use this Action to print out the Http Response html content?

非常感谢

推荐答案

基于Huw的 answer ，此处为完整的工作代码:

Building on the answer by Huw, here is the full working code:

import play.api.test._  
def getStringFromAction(action:Action[AnyContent]):String = {
  val request = new FakeRequest("fakeMethod", "fakeUrl", new FakeHeaders, "fakeBody")
  val result = action.apply(request).run
  import scala.concurrent.duration._
  Helpers.contentAsString(result)(1000 millis)
}

您将需要包括以下库(在Play中默认不包含):play-test_2.11.jar，selenium-java.jar，selenium-api.jar，selenium-chrome-driver.jar，selenium-firefox-driver.jar，selenium-remote-driver.jar，selenium-htmlunit-driver.jar，，htmlunit-core-js.jar和htmlunit.jar.这些在Play或Activator发行版中可用.您还可以在build.sbt中添加依赖项，如在此处说明.

You will need to include the following libraries (not included by default in Play): play-test_2.11.jar, selenium-java.jar, selenium-api.jar, selenium-chrome-driver.jar, selenium-firefox-driver.jar, selenium-remote-driver.jar, selenium-htmlunit-driver.jar, fluentlenium-core.jar, htmlunit-core-js.jar and htmlunit.jar. These are available in the Play or Activator distribution. You can also add a dependency in build.sbt as explained here.
