A Clojure library to handle WebFinger interactions for you.

Usage

Finger

(finger "acct:valerauko@pawoo.net")

Fetches the WebFinger representation of the given user then parses it into a hashmap.

If any errors occur (404 not found, unsupported scheme, invalid JSON/XML) in the process, the used libraries' errors are thrown as-is.

Properties are not supported yet.

Links

(let [user (finger "acct:valerauko@pawoo.net")]
  (link user "self"))
; or even
(-> "acct:valerauko@pawoo.net" finger (link "self"))

It returns the first link node with a rel matching the given parameter.

Represent

(def user-map
  {:subject "acct:valerauko@pawoo.net"
   :aliases ["https://pawoo.net/@valerauko" "https://pawoo.net/users/valerauko"]
   :links [{:rel "http://webfinger.net/rel/profile-page"
            :type "text/html"
            :href "https://pawoo.net/@valerauko"}
           {:rel "self"
            :type "application/activity+json"
            :href "https://pawoo.net/users/valerauko"}]})
(represent user-map)
(represent user-map :as :json)
(represent user-map :as :xml)

Returns a string representing the user as WebFinger JSON or XML. You can pass the format in with :as (it defaults to JSON).

Host meta

(host-meta "https://pawoo.net/.well-known/webfinger?resource={uri}")

Generates the host-meta XML for your host. The provided parameter is embedded in the XML without any adjustments.
