Missing form parameters in Compojure POST request

Question

I\'m having problems getting the form parameters in the following Compojure example:

(ns hello-world
  (:use compojure.core, ring.adapter.jetty)
  (:require

Answer 2

Have you taken into account this:

As of version 0.6.0, Compojure no longer adds default middleware to routes. This means you must explicitly add the wrap-params and wrap-cookies middleware to your routes.

I tried your example with my current setup and it worked. I have included the following: require [compojure.handler :as handler] and (handler/api routes).

Answer 3

You can just give a list of parameters; compojure will automatically get them out of POST/GET params accordingly. If you need to do more complex stuff you can, but I've never looked into how. For example, here's a snippet from the code for 4clojure:

(POST "/problems/submit" [title tags description code]
  (create-problem title tags description code))

Answer 4

This is a great example of how to handle parameters

(ns example2
  (:use [ring.adapter.jetty             :only [run-jetty]]
    [compojure.core                 :only [defroutes GET POST]]
    [ring.middleware.params         :only [wrap-params]]))

(defroutes routes
  (POST "/" [name] (str "Thanks " name))
  (GET  "/" [] "<form method='post' action='/'> What's your name? <input type='text' name='name' /><input type='submit' /></form>"))

(def app (wrap-params routes))

(run-jetty app {:port 8080})
