AuthTokenFactory
Stay organized with collections
Save and categorize content based on your preferences.
Provides authorization tokens for accessing the provider's service account on Fleet Engine
via gRPC. The factory ensures that there is always a valid access token available. The access
token should have a remaining minimum lifetime of at least 5 minutes to allow for requests to
complete. That means that the access token factory must automatically renew expiring tokens.
It should also minimize the number of token refreshes by re-using a token until its lifetime
nears its end.
Public Methods
Returns the value for an "Authorization" HTTP request header for a gRPC call to the
Fleet Engine.
Parameters
| context |
Additional information used during auth token minting. |
