Standard Ring middleware functions for handling JSON requests and responses.
To install, add the following to your project :dependencies:
[ring/ring-json "0.3.1"]
The wrap-json-response middleware will convert any response with a
collection as a body (e.g. map, vector, set, seq, etc) into JSON:
(use '[ring.middleware.json :only [wrap-json-response]]
'[ring.util.response :only [response]])
(defn handler [request]
(response {:foo "bar"}))
(def app
(wrap-json-response handler))The wrap-json-body middleware will parse the body of any request
with a JSON content-type into a Clojure data structure:
(use '[ring.middleware.json :only [wrap-json-body]]
'[ring.util.response :only [response]])
(defn handler [request]
(prn (get-in request [:body "user"]))
(response "Uploaded user."))
(def app
(wrap-json-body handler {:keywords? true :bigdecimals? true}))The wrap-json-params middleware will parse any request with a JSON
content-type and body and merge the resulting parameters into a params
map:
(use '[ring.middleware.json :only [wrap-json-params]]
'[ring.util.response :only [response]])
(defn handler [request]
(prn (get-in request [:params "user"]))
(response "Uploaded user."))
