These credentials require an "audience" claim. This claim identifies the intended recipient of the bearer token. The constructor arguments determine the claims for the JWT that is sent with requests. Usually, you'll construct these credentials with one of the helper constructors as shown in the next section. To create JWT credentials using a Google service account private key JSON file:: audience = 'https://pubsub.googleapis.com/google.pubsub.v1.Publisher' credentials = jwt.Credentials.from_service_account_file( 'service-account.json', audience=audience) If you already have the service account file loaded and parsed:: service_account_info = json.load(open('service_account.json')) credentials = jwt.Credentials.from_service_account_info( service_account_info, audience=audience) Both helper methods pass on arguments to the constructor, so you can specify the JWT claims:: credentials = jwt.Credentials.from_service_account_file( 'service-account.json', audience=audience, additional_claims={'meta': 'data'}) You can also construct the credentials directly if you have a :class:`~google.auth.crypt.Signer` instance:: credentials = jwt.Credentials( signer, issuer='your-issuer', subject='your-subject', audience=audience) The claims are considered immutable. If you want to modify the claims, you can easily create another instance using :meth:`with_claims`:: new_audience = ( 'https://pubsub.googleapis.com/google.pubsub.v1.Subscriber') new_credentials = credentials.with_claims(audience=new_audience) Nctt| ||_||_||_||_||_||_|i}||_ y)a| Args: signer (google.auth.crypt.Signer): The signer used to sign JWTs. issuer (str): The `iss` claim. subject (str): The `sub` claim. audience (str): the `aud` claim.

Like :class:`Credentials`, this class uses a JWT as the bearer token for authentication. However, this class does not require the audience at construction time. Instead, it will generate a new token on-demand for each request using the request URI as the audience. It caches tokens so that multiple requests to the same URI do not incur the overhead of generating a new token every time. This behavior is especially useful for `gRPC`_ clients. A gRPC service may have multiple audience and gRPC clients may not know all of the audiences required for accessing a particular service. With these credentials, no knowledge of the audiences is required ahead of time. .. _grpc: http://www.grpc.io/ Nctt| ||_||_||_||_||_|i}||_tj||_ y)a Args: signer (google.auth.crypt.Signer): The signer used to sign JWTs. issuer (str): The `iss` claim. subject (str): The `sub` claim. additional_claims (Mapping[str, str]): Any additional claims for the JWT payload. token_lifetime (int): The amount of time in seconds for which the token is valid.
