Making POST query on PlayServiceCall

Question

I have a PlayServiceCall that is supposed to handle the GraphQL POST query. The code is below -

override def restPostCall: PlayServiceCall[String, String] = PlayServiceCall { request =>

    Action.async(parse.json) { request =>
      val query = (request.body \ "query").as[String]
      val operation = (request.body \ "operationName").asOpt[String]
      val variables = (request.body \ "variables").toOption.map {
        case obj: JsObject => obj
        case _ => Json.obj()
      }

      QueryParser.parse(query) match {
        // query parsed successfully, time to execute it!
        case Success(queryAst) ⇒
          executeGraphQLQuery(queryAst, operation, variables getOrElse Json.obj())

        // can't parse GraphQL query, return error
        case Failure(error: SyntaxError) ⇒
          Future.successful(BadRequest(Json.obj("error" → error.getMessage)))
      }
    }
  }

The code is same as the one explained in the Getting Started page on Sangria website and also the code of example project on Github by Sangria. Here graphqlBody method handles the POST request of GraphQL.

When I send the GraphQL query by POST method it gives following error -

For request 'POST /graphql' [Invalid Json: Unrecognized token 'query': was expecting ('true', 'false' or 'null') at [Source: akka.util.ByteIterator$ByteArrayIterator$$anon$1@10f6774; line: 1, column: 7]]

Can anyone please help how to send the GraphQL query by POST method with Sangria.

Hey guys I just found the solution. The query is still needed to be sent in JSON format like this

{
"query" : "query HeroAndFriends { hero {name friends { name }}}"
}
