compojure/http-kit redirection

[JvJ]

Hi, I'm starting a web app with compojure and http-kit.  I would like to have one request redirect to another page, but I'm not sure how:

(defroutes app

  (GET "/ws" ws-handler) ; Websocket connection

  (GET "/user/:id" [id] ;; I want to redirect to index.html?user=id

       )

  (resources "/"))

When I get the /user/:id path, I would like to return index.html?user=id.  How can that be done?

Also, how to I interpret URL params using defroutes?

Thanks.

Return a HTTP redirect response. So for example, you could do:

  (GET "/user/:id" [id]

    {:status 302

     :headers {"Location" (str "/index.html?user=" id)}

     :body nil})

For convenience, Ring has the ring.util.response/redirect function to make this more concise:

  (GET "/user/:id" [id]

    (redirect (str "/index.html?user=" id)))

The same way you interpret route parameters, but you'll need to add the ring.middleware.params/wrap-params middleware to your handler.
