clojure - 如何在 compojure Web 项目的 noir 会话中保存用户？

Question

我必须在会话中保存用户名，但我似乎无法使其工作。这是我的代码（sesh 是黑色会话）：

(defn set-loggedin [username password]
(do
(sesh/put! :username (:user username))
(sesh/put! :password (:pass password))))

(defn login-handler [username password]
(let [user (datab/login username password)]
(if (empty? user)
(view/login-form "Wrong username/password")
(do
(set-loggedin username password)
(response/redirect "/main")))))

(defroutes app-routes
(GET "/" [] (view/login-form "" ))
(POST "/" [username password] (login-handler username password))
(GET "/main" [] (view/main-page))
(route/resources "/")
(route/not-found "Not Found"))

(def app
(sesh/wrap-noir-session
(wrap-defaults  app-routes (assoc-in site-defaults [:security :anti-forgery] 
false))))

这是打嗝的主页，当我登录时它不显示用户：

(defn main-page []
(html[:head [:title "main"]] [:body
                             (sesh/get :username)] ))

任何帮助，将不胜感激！

In your set-loggedin function, you are trying to get the :user key from 'username', which I suspect is a string and the :pass key from 'password', which is probably a string.

The do is also unnecessary in a function definition so try this:

(defn set-loggedin [username password]
  (sesh/put! :username username)
  (sesh/put! :password password)))
