使用Play 2.4.6和WS向一系列宁静的API请求数据,但最后添加我遇到了一个问题,我可以弄清楚如何修复.

简而言之,我有一些像这样的代码:

    def testws = Action { implicit request =>
    try {
        Async {
            WS.url("https://someUrl").post(someodyRequest).map { response =>
            Ok("got result from ws")
            }.recover{
                case e: Throwable =>
                    log.warn(s"unexpected error fetching API ", e)
            }
        }
    } catch {
        case _  => Ok("error")
    }
}

在我的本地机器上,.recover块永远不会被执行,但是,在生产中.recover总是在运行,throwable的跟踪轨迹是这样的:
