Classes
A base class for retrieving service tokens. This allows for different clients to be used & parameters to be |
- class src.ska_src_api_accounting.oauth2.oauth2_token.OAuth2ServiceToken(shortname, default_scopes, audience, client, iam_token_endpoint, try_use_cache=True, cache=None, cache_key_prefix='X', additional_scopes=None, logger=src_logger)
Bases:
abc.ABCA base class for retrieving service tokens. This allows for different clients to be used & parameters to be easily modified and restricted, e.g. scope locked storage.[read|write|modify]:/* tokens for download and upload.
- async get(force_renew=False)
Retrieve an access token for the configured OAuth2 client.
