验证播放请求的parse.json [英] parse.json of authenticated play request

问题描述

我已经设置了验证我的应用程序就是这样，总是让当一个用户名，并提供了API密钥是123：

I've set up authentication in my application like this, always allow when a username is supplied and the API-key is 123:

object Auth  {
    def IsAuthenticated(block: => String => Request[AnyContent] => Result) = {
      Security.Authenticated(RetrieveUser, HandleUnauthorized) { user =>
        Action { request =>
          block(user)(request)
        }
      }
    }

    def RetrieveUser(request: RequestHeader) = {

      val auth = new String(base64Decode(request.headers.get("AUTHORIZATION").get.replaceFirst("Basic", "")))
      val split  = auth.split(":")
      val user = split(0)
      val pass = split(1)
      Option(user)
    }

    def HandleUnauthorized(request: RequestHeader) = {
      Results.Forbidden
    }

    def APIKey(apiKey: String)(f: => String => Request[AnyContent] => Result) = IsAuthenticated { user => request =>

      if(apiKey == "123")
        f(user)(request)
      else
        Results.Forbidden
    }

}

我希望再在我的控制器（TESTOUT在这种情况下）来定义一个方法，该方法使用请求作为唯一的应用程序/ JSON。现在，在我加入的认证，我会说高清TESTOUT =动作（parse.json）{...}，但现在，我使用的身份验证，我怎么能到混合添加parse.json，使这项工作？

I want then to define a method in my controller (testOut in this case) that uses the request as application/json only. Now, before I added authentication, I'd say "def testOut = Action(parse.json) {...}", but now that I'm using authentication, how can I add parse.json in to the mix and make this work?

  def testOut = Auth.APIKey("123") { username => implicit request =>

    var props:Map[String, JsValue] = Map[String, JsValue]()
    request.body  match {
      case JsObject(fields) => { props = fields.toMap }
      case _ => {} // Ok("received something else: " + request.body + '\n')
    }

    if(!props.contains("UUID"))
      props.+("UUID" -> UniqueIdGenerator.uuid)

    if (!props.contains("entity"))
      props.+("entity" -> "unset")

    props.+("username" -> username)

    Ok(props.toString)
  }

作为奖励问题，为什么只UUID添加到地图的道具，而不是实体和用户名？

As a bonus question, why is only UUID added to the props map, not entity and username?

很抱歉的小白因素，我想学习Scala和在同一时间播放。 ： - ）

Sorry about the noob factor, I'm trying to learn Scala and Play at the same time. :-)

推荐答案

事实证明，我并不需要在所有使用bodyparser，request.body有我可以使用一个asJson功能。所以，我利用这个做到以下几点。这项工作，我可以继续我的工作，但我还是不太明白如何在这里得到一个JSON解析器的身体。学习中...; - ）

It turns out that I don't need to use a bodyparser at all, request.body has a asJson function that I can use. So I exploited this to do the following. This work, and I can continue my work, but I still don't quite understand how to get a JSON body parser in here. Learning in progress… ;-)

def testOut = Auth.APIKey("123") { username => request =>

  var props:Map[String, JsValue] = Map[String, JsValue]()
  request.body.asJson  match {
    case None => {}
    case Some(x) => {
      x match {
        case JsObject(fields) => { props = fields.toMap }
        case _ => {} // Ok("received something else: " + request.body + '\n')
      }
    }
  }

  if(!props.contains("UUID"))
    props += "UUID" -> toJson(UniqueIdGenerator.uuid)

  if(!props.contains("entity"))
    props += "entity" -> toJson("unset")

  props += "should" -> toJson("appear")
  props += "username" -> toJson(username)

  Ok(props.toString)
}
