如何使用 Scala 和 Play Framework 检查 200 OK 响应状态

Question

我有一个跟随者 class 负责使用 POST.

向 URL 发送 JSON 消息

import play.api.libs.ws._

class Worker extends Actor {
  val logger: Logger = Logger("superman")
  val supermanURL = "http://localhost:9000/superman/send"

  def receive = {

    case message: JsValue => {
      val transactionID = (message \ "transactionID").get
      println("Received JSON Object =>" + message)
      val responseFromSuperman = WS.url(supermanURL).withHeaders("Content-Type" -> "application/json").post(message)

      responseFromSuperman.map(
        result => {

          //TODO: Make sure to only log if response status is 200 OK

          logger.info("""Message="ACK received from Superman" for transactionID=""" + transactionID)}
      ).recover { case error: Throwable =>
        logger.error("""Message="NACK received from Superman" for transactionID=""" + transactionID) + " errorMessage:" + error.getLocalizedMessage()
      }
    }

  }

}

所以，如果您查看我上面的 TODO，我想添加一个响应类型 200 OK 的检查。当前的实现没有这样做，即使我手动发送 BadRequest，它也会记录消息。我尝试检查 result.allHeaders 其中 returns:

Map(Date -> Buffer(Wed, 27 Jan 2016 21:45:31 GMT), Content-Type -> Buffer(text/plain; charset=utf-8), Content-Length -> Buffer(7))

但没有关于响应状态的信息200 OK

Answer 1

简单：

import play.api.http.Status

if(result.status == Status.OK) {
  // ...
}

Answer 2

也许我在这里遗漏了一些东西，但您的回复 "status"。所以你可以这样做：

WS.url(url).withHeaders("Content-Type" -> "application/json").post(message).map{
    case response if ( response.status == OK) => //DO SOMETHING?
}
