How to return 401 error as a json format in Clojure Liberator?

I'm using liberator for REST service and my content type is json.

When :authorized?(or other decisions) fails it returns text/html which i don't want.

I need liberator to return json data format for all type of errors.

Solution

  • Handlers can be used to customise what to do in different cases like handle ok, resource is not found or user is not authenticated. For example:

    (resource
  :available-media-types ["application/json"]
  :authorized? (fn [ctx] ...)
  :handle-unauthorized {:message "You need to be authenticated"}
  :exists? (fn [ctx] ...)
  :handle-not-found {:message "Resource not found"})

    As in other cases, handler can be a constant value or a function that will produce it.
