Hi @Scaramacci,
If you are starting out, it's always best to keep things as bare as
possible until you discover a better way.
If as you say you can save the usr/pwd, and the decision to keep or replace
the token is entirely left to the token provider, then I think something
like the following below, may be suitable.
For anyone interested in learning the ins and outs of OO vs Functional,
static typing vs. dynamic, I highly recommend the Programming Languages
Specialization on Coursera.
(defonce user-tokens (atom {:users {}))
(defn get-updated-token [usr pwd tok]
;; Returns tok if still valid or a new token if expired/expiring.
)
(defn get-token [usr, psw]
(let [f (fn f [tok]
[tok, (fn [] (f (get-updated-token usr psw tok)))])]
(let [path [:users usr]
[_ thunk] (or (get-in @user-tokens path) (f nil))]
(first (swap! user-tokens assoc-in path (thunk))))))
(defn geturl [url]
(client/get url {:oauth-token (get-token "user" "pwd")}))
