Verify token validity about rocket_oauth2 HOT 6 CLOSED

What kind of validation are you trying to do? I expect the answer to be pretty specific to the API that provides the access_token, so this may be better asked there (or it may be in their documentation).

I am using github OAuth as a mean of user identification. Once they're logged and I have access to the token, I'd like to use this to validate others endpoint.
I know how to validate a github token but I am wondering if there is a some specific workflow in rocket_oauth2 to handle this lifecycle? (token refresh, invalidation if expired, ..)

from rocket_oauth2.

Although the TokenResponse includes the refresh_token and expires_in values if the authorization server provided them, I would consider actually using the values as out of scope for rocket_oauth2. Since the only sure way to validate an access token is to attempt to use it, rocket_oauth2 would need to have a validation mechanism for every provider in order for this to actually work.

rocket_oauth2 does provide a convenient way to make that refresh request, at least: https://docs.rs/rocket_oauth2/0.3.0/rocket_oauth2/struct.OAuth2.html#method.refresh

Thanks!

@jebrosen To check a Github token both client_id and client_secret are needed. Is there a way to get this from OAuth2 in an arbitrary endpoint?

@jeluard It can't be accessed via OAuth2, but I would be happy to accept a PR for that.

There is also https://docs.rs/rocket_oauth2/0.3.1/rocket_oauth2/struct.OAuthConfig.html#method.from_config, which can be used once at startup to read the configuration in the same way OAuth2::fairing() does. That would allow you to store the client_id and client_secret in managed state somewhere.
