How do I get the URL params into the request map in Pedestal? I am assuming that this needs the use of an interceptor? However the Pedestal documentation (or severe lack thereof) does not make this at all clear. Thanks.
Query parameters are parsed automatically by Pedestal, and the resulting map is placed in the request map under the :query-params key.
As a simple example, start with the pedestal-service template and use the following definitions:
(defn home-page
[request]
(ring-resp/response (format "Hello with params: %s" (:query-params request))))
(defroutes routes
[[["/" {:get home-page}]]])
Now if you browse to http://localhost:8080/?param=true&other=1234, you should see Hello world with paramters: {:param "true", :other "1234"}.
