lifetime
- life time value in seconds. The value should be at most 43200 (12 hours). If the token is used for calling a Google API, then the value should be at most 3600 (1 hour). If the given value is 0, then the default value 3600 will be used when creating the credentials.- Returns:
- the cloned service account credentials with the given custom life time
-
createWithUseJwtAccessWithScope
Clones the service account with a new useJwtAccessWithScope value. This flag will be ignored if universeDomain field is different fromCredentials.GOOGLE_DEFAULT_UNIVERSE
.- Parameters:
useJwtAccessWithScope
- whether self-signed JWT with scopes should be used- Returns:
- the cloned service account credentials with the given useJwtAccessWithScope

getRequestMetadata
Description copied from class:Credentials
Get the current request metadata without blocking.This should be called by the transport layer on each request, and the data should be populated in headers or other context. The implementation can either call the callback inline or asynchronously. Either way it should never block in this method. The executor is provided for tasks that may block.
The default implementation will just call
Credentials.getRequestMetadata(URI)

"-bin"
and for the corresponding values to be base64 encoded.- Overrides:
