Expand description

A TokenProvider has a single method to implement get_token_with_subject. Implementations are free to perform caching or always return a Request in the TokenOrRequest.

Required methods

Like TokenProvider::get_token, but allows the JWT “subject” to be passed in.

Once a response has been received for a token request, call this method to deserialize the token (and potentially store it in a local cache for reuse until it expires).

Provided methods

Attempts to retrieve a token that can be used in an API request, if we haven’t already retrieved a token for the specified scopes, or the token has expired, an HTTP request is returned that can be used to retrieve a token.

Note that the scopes are not sorted or in any other way manipulated, so any modifications to them will require a new token to be requested.
