ring.middleware和compojure：带关键字的params [英] ring.middleware and compojure: params with keywords

问题描述

在我的网络处理程序中，我定义了以下内容：

In my web handler, I have the following defined:

(:require ... 

[ring.middleware.cookies :refer [wrap-cookies]]
            [ring.middleware.multipart-params :refer [wrap-multipart-params]]
            [ring.middleware.params :refer [wrap-params]]
            [ring.middleware.keyword-params :refer [wrap-keyword-params]]
            [ring.middleware.content-type :refer [wrap-content-type]]
            [ring.middleware.format-response :refer [wrap-restful-response]
...)

(def app
  (-> (routes home/my-routes)
      (wrap-cookies)
      (wrap-params)
      (wrap-multipart-params)
      (wrap-keyword-params))))

一切正常。使用看起来像../test?foo=123的URL测试curl给我一个看起来像{：foo 123}的params映射。但是，显示为关键字的字符串实际上是一个字符串：（keyword？：foo）返回false。

Everything works. Testing with curl using a URL that looks like "../test?foo=123" gives me a params map that looks like {:foo 123}. However, what appears as a keyword is actually a string: (keyword? :foo) returns false.

我已经尝试重新排列处理程序， ，但无济于事。有什么关于compojure的是将关键字转换回字符串？感谢

I've tried rearranging the handlers and removing them one at a time, but to no avail. Is there something about compojure that is converting the keywords back into strings? Thanks

推荐答案

wrap-keyword-params code> wrap-params 和 wrap-multipart-params ，因此您的应用程序应如下所示：

wrap-keyword-params middleware should be run after wrap-params and wrap-multipart-params, so your app should look like:

(def app
  (-> (routes home/my-routes)
      (wrap-keyword-params)
      (wrap-cookies)
      (wrap-params)
      (wrap-multipart-params))))
