Clojure 如何在Aleph中处理websocket断开连接(从页面重新加载)?_Clojure_Websocket - Fatal编程技术网

Clojure 如何在Aleph中处理websocket断开连接(从页面重新加载)?

Clojure 如何在Aleph中处理websocket断开连接(从页面重新加载)?,clojure,websocket,Clojure,Websocket,我已经使用aleph编写了一个基于事件的websocket处理程序。核心文件如下所示: (defn handle-message "Handle a message" [message] (event/dispatch message)) (defn websocket-handler "Handle websocket connections." [client-node connection-data] (map* #(handle-message (message

我已经使用aleph编写了一个基于事件的websocket处理程序。核心文件如下所示:

(defn handle-message
  "Handle a message"
  [message]
  (event/dispatch message))

(defn websocket-handler
  "Handle websocket connections."
  [client-node connection-data]
  (map* #(handle-message (message/create client-node connection-data %)) client-node))

(defn -main
  "Start the http server and start handling websocket connections."
  [& args]
  (myapp.routes.api/add-events)
  (start-http-server websocket-handler {:port 8080 :websocket true}))

这很好,我有一些事件可以工作并给出预期的输出。当我重新加载页面时,它停止工作。有什么问题吗?我假设发生了断开/重新连接。如何管理服务器端的断开连接?

在客户端连接功能中,添加一个fn,以处理通道端关闭时的操作:

(defn connection-handler [channel request]
 (lamina/on-closed channel handle-client-disconnected-fn)
)

(defroutes my-routes
  (GET "/my-website-path" [] (wrap-aleph-handler connection-handler))
)

(start-http-server
    (->
      my-routes
      (wrap-session)
      (wrap-file "./public")
      (wrap-file-info)
      (wrap-stacktrace)
      (wrap-ring-handler)
    )
    {:port 8080 :websocket true}
)

编辑:在实践中,检查它们是否尚未连接,以便您不会多次添加处理程序

什么是事件/调度?
