用bidi包装资源处理程序 [英] Wrapping resource handlers with bidi

问题描述

如何使用朋友和比迪包装资源处理程序？

How can I use friend and bidi to wrap resource handlers?

我已经成功地使oAuth验证了路由：

I've succeeded in getting oAuth to authenticate a route:

(defn auth-handler [request] (friend/authorize #{::user}
                                               {:status 200
                                                :body   "a secret"}))

(def routes ["/" {true auth-handler}])

(def app (make-handler routes))

(web/run-dmc (-> app
                   var
                   (friend/authenticate
                     {:allow-anon? true
                      :workflows   [(oauth/workflow
                                      {:client-config client-config
                                       :uri-config    uri-config
                                       :credential-fn credential-fn})]})
                   (wrap-resource "public")
                   (wrap-defaults site-defaults)
                   ))

这适用于'/'路线，但我想确保某些资源可以

This works on the '/' route, but I would like to make sure some resources can not be reached without authing first.

这似乎可以通过 friend / wrap-authorize 函数实现：

That seems to be possible with the friend/wrap-authorize function:

我最接近的尝试在auth封装的路由上起作用，但在非/ dev /路由上不匹配：

My closest attempt works on the auth wrapped routes, but does not match on the non /dev/ routes:

(def routes ["/" [["dev/" [[true (friend/wrap-authorize (resources {:prefix "dev/"}) #{::user})]]]
                  [true (resources {:prefix "public/"})]]])


(match-route routes "/dev/index.html")
=>
{:handler #object[cemerick.friend$wrap_authorize$fn__24411
              0x2400d0be
              "cemerick.friend$wrap_authorize$fn__24411@2400d0be"]}
;correct

(match-route routes "/index.html")
=>
nil
;not correct

我认为我是路线的匹配部分模式 [true（资源{：prefix public /}））] 是错误的，因为当我将其更改为：key index.html确实匹配。

I think I the Matched part for the Route Pattern [true (resources {:prefix "public/"})] is wrong because when I change it to a :key the `index.html' does match.

如何将非/ dev / *路由与公共资源匹配？

How can I match non /dev/* routes to the public resources?

推荐答案

这里的主要问题是资源路由应该是

The main problem here is that the resource route should be

["" (resources {:prefix "public/"})]

空字符串而不是 true 。

文档确实指出：模式匹配后，路径的其余部分被添加到

The documentation does state: After the pattern is matched, the remaining part of the path is added to the given prefix.

但是坦率地说，我认为这是非常令人惊讶的行为。

But frankly I consider this to be pretty surprising behavior.

我做了一个最小的示例项目在这里成功路由/index.html
https://github.com/timothypratley/bidi-r esources

I made a minimal example project here that successfully routes /index.html https://github.com/timothypratley/bidi-resources

值得注意的是，请求/index.html2会导致异常，这完全不是我所期望的。我期待的是404。o_O

Notably, requesting /index.html2 results in an exception, which is again not what I expected at all. I was expecting a 404. o_O

我真的很喜欢ClojureScript中的bidi，但到目前为止，我发现它在服务器端是一个艰难的口号……我得到了弄清楚为什么 true 不起作用的原因是，用我自己的版本覆盖资源定义，该版本打印出输入内容，并看到：remainder 为空。

I really like bidi in ClojureScript, but so far am finding it a tough slog on the server side... The way I got a clue into why true doesn't work is by overwriting the Resources definition with my own version that printed out the inputs, and saw that :remainder was empty.
