如何在Play测试中从基于InputStream的结果中获取内容

我在Play 2.6上,使用Java

我的控制器返回:

public Result xml() {
    return Results.ok(new ByteArrayInputStream("<someXml />".getBytes()));
}

我想在测试中解析结果:

Result result = new MyController().xml();    
play.test.Helpers.contentAsString(result)

抛出

failed: java.lang.UnsupportedOperationException: Tried to extract body from a non strict HTTP entity without a materializer, use the version of this method that accepts a materializer instead

如何检索测试中输入流发出的结果内容?

正如异常消息所述,由于您的结果是流实体,因此请使用Materializer的版本contentAsString。以下是Play存储库中HelpersTest.java使用该方法的示例:

@Test
public void shouldExtractContentAsStringFromAResultUsingAMaterializer() throws Exception {
    ActorSystem actorSystem = ActorSystem.create("TestSystem");

    try {
        Materializer mat = ActorMaterializer.create(actorSystem);

        Result result = Results.ok("Test content");
        String contentAsString = Helpers.contentAsString(result, mat);
        assertThat(contentAsString, equalTo("Test content"));
    } finally {
        Future<Terminated> future = actorSystem.terminate();
        Await.result(future, Duration.create("5s"));
    }
}

自带kka 2.6的Play 2.8起,“ ActorMaterializer”已被弃用。这是获得“材料化器”的方法

Materializer mat = Materializer.matFromSystem(actorSystem);
