clojure - 如何让 Compojure 收听单个 IP

Question

我已经启动了一个 Compojure (Jetty) 服务器:

(defonce *server* (run-server {:host "localhost" :port 8080} "/*" (servlet routes)))

但是 netstat 仍然显示它正在监听 0.0.0.0:8080，即所有 IP。

传递给 run-server 以使其监听单个 IP 的正确参数是什么？

我认为您将不得不修补 Compojure。它对您的 :host 没有任何作用范围。将此更改更改为 server/jetty.clj似乎有效，但我还没有彻底测试过。

(defn- create-server
  "Construct a Jetty Server instance."
  [options servlets]
  (let [port     (options :port 80)
        host     (options :host "0.0.0.0")
        connector (doto (org.mortbay.jetty.bio.SocketConnector.)
                    (.setPort port)
                    (.setHost host))
        server   (doto (Server.)
                   (.addConnector connector))
        servlets (partition 2 servlets)]
    (when (or (options :ssl) (options :ssl-port))
      (add-ssl-connector! server options))
    (doseq [[url-or-path servlet] servlets]
      (add-servlet! server url-or-path servlet))
    server))
