解析用于Scala的专用字符(例如，è、é和)JSON(2.3.x版)

Question

在为Scala (Version2.3.x)解析专用字符(例如èe、é和for )时，我遇到了问题。由于游戏中的所有内容都是UTF-8编码的，所以上述示例(è，é，和)不应成为问题。我应该提到，我正在使用IntelliJ和sbt进行我的开发。

我已经核实了以下情况：

• 测试文件为UTF-8编码。
• 使用utf-8的javac (javacOptions ++= Seq("-encoding"，"UTF-8"))
• 在标头上设置utf-8 (application/json；charset=utf-8)
• Parse.tolerantJson(请求)是错误的罪魁祸首(参见下面的代码)

测试文件：

{"id":"295b1590-220a-11e4-b641-90e08f355b68","blah":"è é ®"}

主计长：

      def putGuid(streamId: String, guid: UUID) = Action.async(parseToEventContent) {
    implicit request =>
      render.async {
        case mimeType@(Accepts.Json()) =>
          val id = msgId.next()
          (request.body match {
            case JsonEventContent(j) =>
              eventActor ? SendEventMessages.SendJsonEvent(id, streamId, Some(guid), remoteAddress(request), j)
            case ... some other cases...
          }) map {
            case SendEventMessages.Done(`id`) => NoContent
            case ... more error cases.. blah blah ...
            case SendEventMessages.Unknown(`id`) =>
              Logger.info("Message ID: {}. Received an unknown from underlying actors", id.asInstanceOf[AnyRef])
              ServiceUnavailableRetryAfter()
          } recover exceptionErrorHandler
      } }

其中BodyParser是：

  trait EventContent {}
  case class JsonEventContent(data: JsValue) extends EventContent

  def parseToEventContent: BodyParser[EventContent] = BodyParser("eventContent") {
    request =>
      import play.api.libs.iteratee.Execution.Implicits.trampoline
      request.contentType match {
        case Some(MimeTypes.JSON) => parse.tolerantJson(request).map(_.right.map(JsonEventContent(_)))
        case _ => Done(Left(UnsupportedMediaType), Empty)
      }
  }

在我的测试中使用类似于下面的内容会给出“èé”的400个错误，而对于"abc“则给出204个错误(我的源文件是utf-8，javac被设置为在build.sbt中使用uff-8 )：

val eventC = Json.parse(new String(s"""{"id":"295b1590-220a-11e4-b641-90e08f355b68","blah":"è é ®"}""".getBytes("UTF-8"), "UTF-8"))
val eventCJson = eventC.toString().getBytes("UTF-8")

"return 204 when entity has è, é, ® in json event" in new WithApplication(MyFakeApplication()){
  println(s"json=${eventC}")
  val result = assertPutRequest(s"/streams/com.gilt.clickstream/events/295b1590-220a-11e4-b641-90e08f355b68", 204, event = eventCJson, "application/json", "application/json; charset=utf-8")
  contentType(result) must be equalTo None
  contentAsBytes(result) must be equalTo Array()
}

def assertPutRequest(url: String, httpStatus: Int, event: Array[Byte], acceptHeader: String = "application/json", contentTypeHeader: String = "application/json; charset=utf-8")(implicit app: Application) = {
  Akka.system.actorOf(MockEventActor.props, "event")

  val result = route(
    FakeRequest(PUT, url)
      .withHeaders(
        "Accept" -> acceptHeader,
        "Content-Type" -> contentTypeHeader)
      .withRawBody(event)
  )(new Writeable({ j: AnyContentAsRaw => j.raw.asBytes().get}, None)).get

  status(result) must be equalTo httpStatus
  result
}

这个问题的解决方案是升级到JDK1.7。我使用的是JDK1.6，这导致了这个问题。
