export a callback function which updates runtime metadata.
array
updateMetadata(array $metadata, string $authUri = null, callable|null $httpHandler = null)
Updates metadata with the authorization token.
static array|null
fromEnv()
Load a JSON key from the path specified in the environment.
Load a JSON key from the path specified in the environment variable GOOGLE_APPLICATION_CREDENTIALS. Return null if GOOGLE_APPLICATION_CREDENTIALS is not specified.
static array|null
fromWellKnownFile()
Load a JSON key from a well known path.
The well known path is OS dependent:
- windows: %APPDATA%/gcloud/application_default_credentials.json
- others: $HOME/.config/gcloud/application_default_credentials.json
If the file does not exist, this returns null.
