how would you guys implement auto body conversion? about liberator HOT 6 CLOSED

Liberator has the concept of representations. In liberator.representation there is a Protocol Representation which defines a single method as-response. To convert a sequence to a json response the protocol would have to be implemented for sequences. The implementation then dispatches on the media-type to use clojure.data.json in the case that the negotiated media-type is "application/json".

Fortunately there are already implementations for strings, sequences, maps, etc. for the media types text/plain, csv, tsv, application/clojure and application/json in liberator.representation

A simple resource definition would look like this:

(defresource me-can-haz-json
  :available-media-types ["application/json"]
  :handle-ok ["me" "can" "be" "a" {:application "json"}])

In the examples there a more resources, e.g. here: https://github.com/clojure-liberator/liberator/blob/master/examples/clj/examples.clj#L123

i already know about this, as i have changed the clojure.data.json function to use the latest version of cheshire on the version of liberator that i have pulled down and have been playing with.

i want to know about dealing with the request.

I'm not sure if I understand what you want? Do you man to automatically parse the request body?

from liberator.

yes
it's a stream, but if the user tells me they are sending me json, then i can run that stream through cheshire.

The most natural implementation IMHO is to use the valid-content-header? decision point:

(defresource foo
:valid-content-header?
(fn [ctx](when %28.equalsIgnoreCase "application/json" %28get-in ctx [:request "content-type"]))
{::parsed-content (parse-stream (get-in ctx [:request :body]))})))

Of course there is room for some to-be-written helper functionsm e.g.:

(parse-body "application/json" chesire/parse-stream "application/clojure" safe-parse-with-clojure-reader)

I'd be happy if you would contribute something like this.

from liberator.

that looks good.
