akka http - 如何将json数据添加到发布请求？

Question

我正在查询一个搜索api，我需要将json中的查询参数添加到发布请求中。

val headers: scala.collection.immutable.Seq[HttpHeader] = scala.collection.immutable.Seq(
    RawHeader("accept", "application/json"), 
    RawHeader("authorization", "xxxxxxxxxxxxxxxxxxxx"), 
    RawHeader("content-type", "application/json"), 
    RawHeader("x-customer-id", "123456789") 
) 

val formData = FormData(Map(
     "Keywords" -> "query", "Count" -> "25" 
    )) 

val request = HttpRequest(HttpMethods.POST, "https://api.xxx.com/services/xxx/v1/search?client_id=xxxxxx", headers, formData.toEntity) 

将使用formData.toEntity发送它作为JSON在帖子的主体？

我创建了搜索查询的类别和序列化，并创造了一个HttpEntity像这样：

case class SearchObject(keyWords: String, count: Int) 

val reqHeaders: scala.collection.immutable.Seq[HttpHeader] = scala.collection.immutable.Seq(
    RawHeader("accept", "application/json"), 
    RawHeader("authorization", "xxxxxxxxxxxxxxxxxxxx"), 
    RawHeader("content-type", "application/json"), 
    RawHeader("x-customer-id", "123456789") 
) 

val searchObject = net.liftweb.json.Serialization.write(req) //req is search object 
val searchObjectEntity = HttpEntity(ContentTypes.`application/json`, searchObject) 
val request = HttpRequest(HttpMethods.POST, "https://api.xxxxxxxx.com/services/xxxxxx/v1/search?client_id=45854689", reqHeaders, searchObjectEntity)
