A Clojure library designed to provide a minimal setup to do an OAuth2 authentication and get a token.
Does not assume you are using it from a webapp. Produces an authorization url. The user can hit the url, authenticate and get back an access code that this lib will exchange for an access token and refresh token.
When using it from a webapp you can redirect the user to the authorization url and provide a redirect url back to your webapp.
Uses clj-http (could probably do with just clj-http-lite)
Provides 3 functions and 1 macro. All take a config for the OAuth2 provider, Google is provided as an example.
request-auth-url - creates the authorization url get-tokens - gets access- and refresh tokens refresh-tokens - use the refresh_token to get a fresh access_token
The macro with-tokens provides convenience to use the tokens to access oauth protected resources. It will execute the body and if the access_token has expired it will auto-refresh it.
