如何在 Ring 处理程序中获取 HttpServletRequest？
有没有办法在 Ring 处理程序中获取 HttpServletRequest 对象？ 我正在使用 Noir 开发一个网络应用程序。我需要在处理 URI 时获取 HttpServletRequest 对象。所以我使用 (noir.request.ring-request) 函数来获取包含 :servlet-request 键的环请求映射，但该值为零。这是正确的方法还是我错过了什么？
以下是代码：
(ns my-app
(:use noir.request))
(defpage [:get "/app"] []
(str (ring-request)))
结果：
{:remote-addr "127.0.0.1", :scheme :http, :query-params {}, :session {}, :form-params {}, :multipart-params {}, :servlet #, :request-method :get, :query-string nil, :content-type nil, :cookies {"ring-session" {:value "eb509a65-d33a-40d2-9646-e2ff785428b0"}}, :uri "/app", :server-name "127.0.0.1", :params {}, :headers {"cookie" "ring-session=eb509a65-d33a-40d2-9646-e2ff785428b0", "accept-charset" "GBK,utf-8;q=0.7,*;q=0.3", "accept-language" "en-US,en;q=0.8,zh-CN;q=0.6,zh;q=0.4", "accept-encoding" "gzip,deflate,sdch", "accept" "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", "user-agent" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.106 Safari/535.2", "connection" "keep-alive", "host" "127.0.0.1:8080"}, :servlet-request #, :content-length nil, :server-port 8080, :character-encoding nil, :servlet-response #, :body #, :servlet-context #}
Is there a way to get the HttpServletRequest object in a Ring handler?
I am using Noir to develope a web app. I need to get the HttpServletRequest obj when handling a URI. So I use the (noir.request.ring-request) function to get back the ring request map which contains :servlet-request key, but the value is nil. Is this the right way to do it or do I miss something?
following is the code:
(ns my-app
(:use noir.request))
(defpage [:get "/app"] []
(str (ring-request)))
the result:
{:remote-addr "127.0.0.1", :scheme :http, :query-params {}, :session {}, :form-params {}, :multipart-params {}, :servlet #, :request-method :get, :query-string nil, :content-type nil, :cookies {"ring-session" {:value "eb509a65-d33a-40d2-9646-e2ff785428b0"}}, :uri "/app", :server-name "127.0.0.1", :params {}, :headers {"cookie" "ring-session=eb509a65-d33a-40d2-9646-e2ff785428b0", "accept-charset" "GBK,utf-8;q=0.7,*;q=0.3", "accept-language" "en-US,en;q=0.8,zh-CN;q=0.6,zh;q=0.4", "accept-encoding" "gzip,deflate,sdch", "accept" "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", "user-agent" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.106 Safari/535.2", "connection" "keep-alive", "host" "127.0.0.1:8080"}, :servlet-request #, :content-length nil, :server-port 8080, :character-encoding nil, :servlet-response #, :body #, :servlet-context #}

看起来环请求映射是根据您用于网络服务器的适配器构建的。对于jetty，这发生在ring.adapter.jetty中：
https://github.com/ring-clojure/ring/blob/master/ring-jetty-adapter/src/ring/adapter/jetty.clj
如果我是你，我会创建我自己的适配器，将您需要的内容显式添加到请求映射中。具体来说，您可以替换
为以下内容：
It looks like the ring request map is constructed based on the adapter you are using for the webserver. In the case of jetty, this happens in ring.adapter.jetty:
https://github.com/ring-clojure/ring/blob/master/ring-jetty-adapter/src/ring/adapter/jetty.clj
If I were you, I would create my own adapter that explicitly adds what you need to the request map. Specifically you would replace
with something like:
