默认情况下，在Compojure中使用index.html为/ [英] Serve index.html at / by default in Compojure

问题描述

我有一个名为 index.html 的静态文件，当有人请求 / 时，我想提供。通常，网络服务器默认情况下会执行此操作，但Compojure不会。当有人请求 / ？

I have a static file called index.html that I'd like to serve when someone requests /. Usually web servers do this by default, but Compojure doesn't. How can I make Compojure serve index.html when someone requests /?

这是我用于静态目录的代码：

Here's the code I'm using for the static directory:

; match anything in the static dir at resources/public
(route/resources "/")

推荐答案

这将是一个非常简单的环中间件：

This would be a pretty simple Ring middleware:

(defn wrap-dir-index [handler]
  (fn [req]
    (handler
     (update-in req [:uri]
                #(if (= "/" %) "/index.html" %)))))

只要用这个函数包装你的路由， c $ c> / 在您的其余代码看到它们之前转换为 /index.html 的请求。

Just wrap your routes with this function, and requests for / get transformed into requests for /index.html before the rest of your code sees them.

(def app (-> (routes (your-dynamic-routes)
                     (resources "/"))
             (...other wrappers...)
             (wrap-dir-index)))
