Thanks. I just found out that my middlewares work, I just had to reorder
them like this:
(def app
(->
(handler/api app-routes)
(friend/authenticate {:credential-fn (partial
creds/bcrypt-credential-fn users)
:login-url "/login"
:workflows [
(ajax-login)
]})
(format/wrap-restful-format)
(middleware/wrap-json-body)
(middleware/wrap-json-params)
(middleware/wrap-json-response)
)
)
Now I don't need slurp... still had to change this line in ajax-login,
since the format using these middlewares is a bit different:
(if-let [{:keys [username password] :as creds} (get-in
request [:params :json-params])]
with:
(if-let [{:keys [username password] :as creds}
(clojure.walk/keywordize-keys(:json-params request))]
