Ring middleware for multipart/mixed

Clojure ring / compojure middleware that knows how to parse a multipart/mixed mime type message into the request map.

Add to your project

Add [com.floatbackwards/multipart "0.0.1"] to your project.clj

Available on clojars: multipart

Use with

(:use [ring.multipart-mixed-params])

then

(defroutes main-routes (wrap-multipart-mixed
   (POST "/data" req "OK")))

or

(def app
  (handler/site
   wrap-multipart-mixed
   main-routes))

If the request content-type header contains the content type of multipart/mixed this will put a key of :multiparts into the request map. Otherwise does nothing.

This key will contain a map of content type to seq of streams for each part of the message with that type.

For example a message containing three parts: 2 jpeg images and 1 text/plan would give us the following request map.

{
:body "some multipart/mixed message body - this is what we parse"
... 
  :multiparts {
    "image/jpeg" : (<stream1> <stream2>),
    "text/plain" : (<stream1>)
  }
...}

Each of the parsed elements is available as a stream that can be split, slurped or whatever else you fancy.

Building
