这就是我在浏览器控制台中得到的：

WS-PARSER: received {"eventPhase":2,"origin":"","bubbles":false,"defaultPrevented":false,"srcElement":{"binaryType":"blob","extensions":"","url":"ws://localhost:9000/map-socket/a@a.com","bufferedAmount":0,"readyState":1,"onerror":null,"onopen":null,"onclose":null,"protocol":"","URL":"ws://localhost:9000/map-socket/a@a.com"},"type":"message","returnValue":true,"target":{"binaryType":"blob","extensions":"","url":"ws://localhost:9000/map-socket/a@a.com","bufferedAmount":0,"readyState":1,"onerror":null,"onopen":null,"onclose":null,"protocol":"","URL":"ws://localhost:9000/map-socket/a@a.com"},"source":null,"cancelable":false,"currentTarget":{"binaryType":"blob","extensions":"","url":"ws://localhost:9000/map-socket/a@a.com","bufferedAmount":0,"readyState":1,"onerror":null,"onopen":null,"onclose":null,"protocol":"","URL":"ws://localhost:9000/map-socket/a@a.com"},"ports":[],"timeStamp":1341430631884,"lastEventId":"","cancelBubble":false,"data":"{\"stars\":[{\"x\":\"0.0\",\"y\":\"0.0\",\"own\":\"-1\",\"id\":\"0\",\"units\":\"0\"},{\"x\":\"0.0\",\"y\":\"0.0\",\"own\":\"-1\",\"id\":\"1\",\"units\":\"0\"},{\"x\":\"0.0\",\"y\":\"0.0\",\"own\":\"0\",\"id\":\"2\",\"units\":\"0\"}]}"}

我有两个问题：

1）为什么消息的第一部分（自动）有那么多标题重复？可以吗，我应该这样保留还是可以以某种方式减少样板的数量？

2）为什么消息的第二部分（我的有效负载）中的所有引号都被转义了？

这是制定 JSON 的代码：

val stars = strs.getAll.map(_.asJsValue).toSeq
Json.toJson(
    Map(
        "stars" -> stars
        )
)

asJsValue方法：

  def asJsValue = {
    Json.toJson(
        Map(
            "id" -> id.toString,
            "x" -> x.toString,
            "y" -> y.toString,
            "units" -> units.toString,
            "own" -> getOwnerID.toString
        )
    )
  }

在客户端：

websocket.onmessage = receivedEvent

receiveEvent = (event) ->
  console.log("WS-PARSER: received " + JSON.stringify(event))

  1. 大多数数据是在客户端添加的，只有data值是通过网络发送的
  2. JSON 需要双引号，这就是它们被转义的原因
