Compojure does not bind the fields in a POST form. This is my route def:
(defroutes main-routes
(POST "/query" {params :params}
(debug (str "|" params "|"))
"OK...")
)
When I post a form with fields in it, I get |{}|, i.e. there are no parameters. Incidentally, when I go http://localhost/query?param1=value1, params is not empty, and the values get printed on the server console.
Is there another binding for form fields??
ensure you have input fields with name="zzz" attribute, but not only id="zzz".
html form collects all inputs and posts them using the name attribute
my_post.html
<form action="my_post_route" method="post">
<label for="id">id</label> <input type="text" name="id" id="id" />
<label for="aaaa">aaa</label> <input type="text" name="aaa" id="aaa" />
<button type="submit">send</button>
</form>
my_routes.clj
(defroutes default-handler
;,,,,
(POST "/my_post_route" {params :params}
(str "POST id=" (params "id") " params=" params))
;,,,,
produce response like
id=21 params={"aaa" "aoeu", "id" "21"}
This is a great example of how to handle parameters

(: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})

note: (params "id") return nil for me, i get a correct value with (params :id)
