      WS.url("http://www.google.com").get().map { response =>
        println("Body: " + response.body)
      }
    }
  }
}

我不知道如何解决这个问题，因为Play Docs表明了这一点应该工作。

Answer 1

由于AsyncHttpClient版本存在冲突，因此无法在同一项目中使用Play 2.3和Gatling 2.1。

Play 2.3需要AHC 1.8，而Gatling 2.1需要AHC 1.9。

升级到Play 2.4，升级AHC依赖项，或者将Gatling测试移动到一个单独的项目或模块，其中类路径不会冲突。

Scala Play 2.3 WS.url（...）配置错误
