scala - Akka REST 服务 + 调度

Question

我跟着例子here .它有效，很好。但是现在我需要在 case get:Get => 中执行一些业务逻辑

所需的业务逻辑包括使用 dispatch图书馆。简而言之，我向某个页面发出请求，获取数据，将其包装在某个类中，然后返回它。

我的接收案例是这样的:

case get:Get => {
  get.response.setContentType(MediaType.APPLICATION_JSON)
  val response = Sender.doLogin
  val battery = (response.batteryRemaining / response.batteryCapacity) * 100
  val soc = (response.pluginState + ", " + response.chargingStatus).replaceAll("_", " ")
  val jsonResult = pretty(render(("battery" -> battery) ~ ("soc" -> soc)))
  get OK jsonResult
  // get OK "works"
}

这不起作用:

它似乎也开始发出请求(使用调度库) 后 它响应 HTTP 200 OK .

这里可能有什么问题？
