A very simple web application demonstrating the Sweet-Liberty library. (https://github.com/RJMetrics/sweet-liberty)
Friend the Clojure authentication library attaches a collection of authentication fn / handlers which sweet-lib throws up on trying to parse as JSON.
Example:
[false false true false]
parsing: {}
[false false true false]
parsing: {}
[false false true false]
parsing: nil
[false false false true]
parsing: nil
[false false false true]
parsing: {}
[false false true false]
parsing: nil
[false false false true]
parsing: {}
[false false true false]
parsing: /users
[false true false false]
parsing: {}
[false false true false]
parsing: {:default-landing-uri /app, :login-uri /login, :credential-fn #object[budget_om.server$fn__28154 0x699d4a7c budget_om.server$fn__28154@699d4a7c], :workflows [#object[cemerick.friend.workflows$interactive_form$fn__19471 0x39b10857 cemerick.friend.workflows$interactive_form$fn__19471@39b10857]], :unauthenticated-handler #object[budget_om.server$fn__28152 0x4dee8226 budget_om.server$fn__28152@4dee8226]}
[false false true false]
parsing: /app
[false true false false]
parsing: /login
[false true false false]
parsing: #object[budget_om.server$fn__28154 0x699d4a7c budget_om.server$fn__28154@699d4a7c]
[false false false false]
parsing: [#object[cemerick.friend.workflows$interactive_form$fn__19471 0x39b10857 cemerick.friend.workflows$interactive_form$fn__19471@39b10857]]
[false false true false]
That last line [#object[cemerick.friend.workflows$interactive_form$fn__19471 0x39b10857 cemerick.friend.workflows$interactive_form$fn__19471@39b10857]]
is a Vector of 1 object which cannot be JSON parsed as is.
Resulting in:
{:status 500, :headers {"Content-Type" "application/edn;charset=UTF-8", "Vary" "Accept", "Set-Cookie" ("ring-session=d22473ed-4e13-4a90-943f-3d2d9a669118;Path=/;HttpOnly"), "X-XSS-Protection" "1; mode=block", "X-Frame-Options" "SAMEORIGIN", "X-Content-Type-Options" "nosniff"}, :body "{\"exception-message\":\"Don't know how to write JSON of class cemerick.friend.workflows$interactive_form$fn__19471\"
Was able to get around this with:
(defn json-value-fn
([v]
(if (coll? v)
(apply str (map json-value-fn v)))
(if (or (number? v) (string? v) (nil? v))
v
(str v)))
([_ v] (json-value-fn v)))
