web-services - Play 2.0 中的 WebService (WS) POST - Scala

Question

当我尝试将 map 传递给帖子时，出现此错误:

Cannot write an instance of scala.collection.immutable.Map[java.lang.String,java.lang.String] to HTTP response. Try to define a Writeable[scala.collection.immutable.Map[java.lang.String,java.lang.String]]

这是我的帖子示例:

WS.url("http://mysql/endpoint")
  .post(Map("email" -> "juju@juju.com")).map { response =>
    Logger.logger.debug("response: " + response.body)
  }

怎么了？

Answer 1

这是提示:您必须发送 Map[String, Seq[String]]

WS.url("http://mysql/endpoint")
  .post(Map("email" -> Seq("juju@juju.com"))).map { response =>
    Logger.logger.debug("response: " + response.body)
  }
