akka-http复合json转换

Question

我想使用akka http实现restful http服务。[法]收货和做某事

{
    "user": {
        "userid": 123,
        "reqid": "abcdef",
        "username": "张三"
    },
    "article": {
        "atype": 1,
        "fromdate": "2017-06-27"
    },
    "tags": {
        "fixtags": [
            { "t":"t1", "w": 30 },
            { "t":"t2", "w": 20 },
            { "t":"t3", "w": 10 },
            { "t":"t4", "w": 50 }
        ],
        "atags": [
            { "t":"t5", "w": 30 },
            { "t":"t6", "w": 20 }
        ]
    }
}

案例类

case class Article(atype: Int, fromdate: String)
case class Tag(t: String, w: Double)
case class FixTags(fixtags: List[Tag])
case class ATags(atags: List[Tag])
//case class Tags( fixtags: List[Map[String, Float]], atags: List[Map[String, Float]] )
case class Tags(fixtags: FixTags, atags: ATags)

case class AUserInfo(user: User, article: Article, tags: Tags)
implicit val userFormat1 = jsonFormat3( User )
implicit val artFormat1 = jsonFormat2( Article )
implicit val tagFormat1 = jsonFormat2( Tag )
implicit val ftagFormat1 = jsonFormat1( FixTags )
implicit val atagFormat1 = jsonFormat1( ATags )
implicit val tagsFormat1 = jsonFormat2( Tags )

implicit val userFormat = jsonFormat3( AUserInfo )

路线：

path( "rcmd" / LongNumber ) {
            userid =>
                post {


                    entity( as[AUserInfo] ) { userinfo =>do sth}

asAUserInfo将报告错误：

请求内容格式错误:字段“fixtags”%中期望的对象

或者：

找不到参数um: akka.http.scaladsl.unmarshalling.Unmarshaller的隐式值

有人能帮我吗？

Answer 1

我已经发现了错误:因为我的json字符串格式不适合我的case类。我将case类更改为下面，并修复该错误：

//case class FixTags(fixtags: List[Tag])
//case class ATags(atags: List[Tag])

case class Tags(fixtags: List[Tag], atags: List[Tag])
