我有使用噴霧框架,看起來像以下書面一塊API的Scalatest:噴霧試驗情況下不屬性解組UTF-8編碼的使用JSON HTTPEntity

"correctly deserializes multi-lang title metadata" in { 
    implicit def json4sFormats: org.json4s.Formats = ModelJsonHelper.jsonFormats 

    val v2MultiLangTitle = getStringFromResource("/json_samples/cmp.asset.v2.AssetWriteMultiMetadata.json") 

    //Deserialize 
    val v2AssetEither = HttpEntity(`application/cmp.ela.assetWrite.v2+json`, v2MultiLangTitle).as[Asset] 
    v2AssetEither.isRight shouldEqual true 
    v2AssetEither.right.map(asset => { 
    asset.assetMetadata.getOrElse(List()).size shouldEqual(3) 
    asset.assetMetadata.getOrElse(List())(1).language shouldEqual("es") 
    asset.assetMetadata.getOrElse(List())(1).data.title shouldEqual(Some("Encabezado prueba de AFP")) 
    asset.assetMetadata.getOrElse(List())(2).language shouldEqual("tlh") 
    asset.assetMetadata.getOrElse(List())(2).data.title shouldEqual(Some("Daj jaw AFP")) 
    asset.assetMetadata.getOrElse(List())(0).language shouldEqual("de") 
    asset.assetMetadata.getOrElse(List())(0).data.title shouldEqual(Some("Test AFP Überschrift")) 
    }) 
} 

def getStringFromResource(input: String): String = { 
    Source.fromInputStream(this.getClass.getResourceAsStream(input))(Codec.UTF8).getLines.mkString("") 
} 

正在處理的JSON是以下

{ 
    "assetMetadata" : [ 
    { 
     "title": "Test AFP Überschrift", 
     "language": "de" 
    }, 
    { 
     "title": "Encabezado prueba de AFP", 
     "language": "es" 
    }, 
    { 
     "title": "Daj jaw AFP", 
     "language": "tlh" 
    } 
    ] 
} 

,故障發生在德國元音:

[info] - correctly deserializes multi-lang title metadata *** FAILED *** 
[info] Some("Test AFP �berschrift") did not equal "Test AFP Überschrift" (V2AssetWriteMarshallerSpec.scala:367) 

在表面下,有一些json4s用於解包過程。但是,如果我直接使用json4s解析器,德國字符正確處理:

import scala.io.Source 
import java.io.FileInputStream 
val v = Source.fromInputStream(new FileInputStream("/path/to/project/src/test/resources/json_samples/cmp.asset.v2.AssetWriteMultiMetadata.json")).getLines.mkString("") 
import org.json4s._ 
import org.json4s.native.JsonMethods._ 

val obj = parse(v) 
(obj \ "assetMetadata") 

給我的結果:

res0: org.json4s.JValue = JArray(List(JObject(List((title,JString(Test AFP Überschrift)), .... 

我在噴霧1.3.3和3.2.10 json4s。在HttpEntity該類型的自定義類型,我已經嘗試添加("charset" -> "UTF-8")作爲一個參數,像這樣:

val `application/cmp.ela.assetWrite.v2+json` = register(
    MediaType.custom(
     mainType = "application", 
     subType = "cmp.ela.assetWrite.v2+json", 
     compressible = true, 
     binary = false, 
     parameters = Map[String,String]("charset" -> "UTF-8") 
    ) 
) 

..但是測試還是失敗的無效字符。我如何讓Spray正確解開一個包含國際字符的字符串?
