Getting the POST body data from a POST request to Pedestal

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...)

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"})

Here's more relevant info on defining such handlers in your route tables.
