Getting the POST body data from a POST request to Pedestal - clojure

Question

I have POSTed data to a Pedestal endpoint "/my-post. I have routed that end point as such:
[[["/" {:get landing} ^:interceptors [(body-params/body-params) ...]
["/my-post {:post mypost-handler}
....
So to my mind this means that the body-params interceptor will fire for /my-post too.
In mypost-handler I have:
(defn mypost-handler
[request]
****HOW TO ACCESS THEN FORM DATA HERE ****
)
How do I now access the form data here? I can see from printing the request that I have a #object[org.eclipse.jetty.sever.HttpInputOverHTTP..] which will clearly need further processing before it is useful to me.
(I must say, the documentation for Pedestal is pretty sketchy at best...)

Answer 1

Something like this should work. Note the body-params interceptor on the mypost-handler route
(defn mypost-handler
[{:keys [headers params json-params path-params] :as request}]
;; json-params is the posted json, so
;; (:name json-params) will be the value (i.e. John) of name property of the posted json {"name": "John"}
;; handle request
{:status 200
:body "ok"})
(defroutes routes
[[["/mypost-handler" {:post mypost-handler}
^:interceptors [(body-params/body-params)]
]
]])

The mypost-handler is acting as a Ring handler, i. e. it should accept a Ring request map and return a Ring response map. Thus, you can expect a typical Ring request structure:
(defn mypost-handler
[{:keys [headers params json-params path-params] :as request}]
;; handle request
{:status 200
:body "ok"})
