在Spray POST路由中将Raw JSON提取为String

Question

我有一个POST Spray路由，请求包含一个JSON主体（内容类型“application / json”）。我想要一种方法从我的路线中的这个请求中提取原始JSON。

对于http://host:port/somepath/value1，我想提取帖子正文为TextMsgResponse。但对于http://host:port/somepath/value2，我想提取帖子正文，就像原始Json一样（例如，{ "name":"Jack", "age":30 }

val myRoute = path("somepath" / Segment) { pathSegment => 
post {   //use only POST requests
  pathSegment match {
    case "value1" =>
      entity(as[TextMsgResponse]) { textMsg =>
        complete {
          //do something with the request
          StatusCodes.OK
        }
      } 
    case "value2" => { 
       //here is I want to extract the RAW JSON from the request          
      } 
    }
   }

Answer 1

您可以将extract指令用作

def rawJson = extract { _.request.entity.asString} 
    .
    .
    . 
case "value2" => rawJson{ json =>// use the json 
  }
