"""Creates a secure authorized gRPC channel.
This creates a channel with SSL and :class:`AuthMetadataPlugin`. This
channel can be used to create a stub that can make authorized requests.
Users can configure client certificate or rely on device certificates to
establish a mutual TLS channel, if the `GOOGLE_API_USE_CLIENT_CERTIFICATE`
variable is explicitly set to `true`.
Example::
import google.auth
import google.auth.transport.grpc
import google.auth.transport.requests
from google.cloud.speech.v1 import cloud_speech_pb2
# Get credentials.
credentials, _ = google.auth.default()
# Get an HTTP request function to refresh credentials.
request = google.auth.transport.requests.Request()
# Create a channel.
channel = google.auth.transport.grpc.secure_authorized_channel(
credentials, regular_endpoint, request,
ssl_credentials=grpc.ssl_channel_credentials())
# Use the channel to create a stub.
cloud_speech.create_Speech_stub(channel)
Usage:
There are actually a couple of options to create a channel, depending on if
you want to create a regular or mutual TLS channel.
First let's list the endpoints (regular vs mutual TLS) to choose from::
regular_endpoint = 'speech.googleapis.com:443'
mtls_endpoint = 'speech.mtls.googleapis.com:443'
Option 1: create a regular (non-mutual) TLS channel by explicitly setting
the ssl_credentials::
regular_ssl_credentials = grpc.ssl_channel_credentials()
channel = google.auth.transport.grpc.secure_authorized_channel(
credentials, regular_endpoint, request,
ssl_credentials=regular_ssl_credentials)
Option 2: create a mutual TLS channel by calling a callback which returns
the client side certificate and the key (Note that
`GOOGLE_API_USE_CLIENT_CERTIFICATE` environment variable must be explicitly
set to `true`)::
def my_client_cert_callback():
code_to_load_client_cert_and_key()
if loaded:
return (pem_cert_bytes, pem_key_bytes)
raise MyClientCertFailureException()
try:
channel = google.auth.transport.grpc.secure_authorized_channel(
credentials, mtls_endpoint, request,
client_cert_callback=my_client_cert_callback)
except MyClientCertFailureException:
# handle the exception
Option 3: use application default SSL credentials. It searches and uses
the command in a context aware metadata file, which is available on devices
with endpoint verification support (Note that
`GOOGLE_API_USE_CLIENT_CERTIFICATE` environment variable must be explicitly
set to `true`).
See https://cloud.google.com/endpoint-verification/docs/overview::
try:
default_ssl_credentials = SslCredentials()
except:
# Exception can be raised if the context aware metadata is malformed.
# See :class:`SslCredentials` for the possible exceptions.
# Choose the endpoint based on the SSL credentials type.
if default_ssl_credentials.is_mtls:
endpoint_to_use = mtls_endpoint
else:
endpoint_to_use = regular_endpoint
channel = google.auth.transport.grpc.secure_authorized_channel(
credentials, endpoint_to_use, request,
ssl_credentials=default_ssl_credentials)
Option 4: not setting ssl_credentials and client_cert_callback. For devices
without endpoint verification support or `GOOGLE_API_USE_CLIENT_CERTIFICATE`
environment variable is not `true`, a regular TLS channel is created;
otherwise, a mutual TLS channel is created, however, the call should be
wrapped in a try/except block in case of malformed context aware metadata.
The following code uses regular_endpoint, it works the same no matter the
created channle is regular or mutual TLS. Regular endpoint ignores client
certificate and key::
channel = google.auth.transport.grpc.secure_authorized_channel(
credentials, regular_endpoint, request)
The following code uses mtls_endpoint, if the created channle is regular,
and API mtls_endpoint is confgured to require client SSL credentials, API
calls using this channel will be rejected::
channel = google.auth.transport.grpc.secure_authorized_channel(
credentials, mtls_endpoint, request)
Args:
credentials (google.auth.credentials.Credentials): The credentials to
add to requests.
request (google.auth.transport.Request): A HTTP transport request
object used to refresh credentials as needed. Even though gRPC
is a separate transport, there's no way to refresh the credentials
without using a standard http transport.
target (str): The host and port of the service.
ssl_credentials (grpc.ChannelCredentials): Optional SSL channel
credentials. This can be used to specify different certificates.
This argument is mutually exclusive with client_cert_callback;
providing both will raise an exception.
If ssl_credentials and client_cert_callback are None, application
default SSL credentials are used if `GOOGLE_API_USE_CLIENT_CERTIFICATE`
environment variable is explicitly set to `true`, otherwise one way TLS
SSL credentials are used.
client_cert_callback (Callable[[], (bytes, bytes)]): Optional
callback function to obtain client certicate and key for mutual TLS
connection. This argument is mutually exclusive with
ssl_credentials; providing both will raise an exception.
This argument does nothing unless `GOOGLE_API_USE_CLIENT_CERTIFICATE`
environment variable is explicitly set to `true`.
kwargs: Additional arguments to pass to :func:`grpc.secure_channel`.
Returns:
grpc.Channel: The created gRPC channel.
Raises:
google.auth.exceptions.MutualTLSChannelError: If mutual TLS channel
creation failed for any reason.

client_cert_source_for_mtls (Optional[Callable[[], Tuple[bytes, bytes]]]):
A callback to provide client certificate bytes and private key bytes,
both in PEM format. It is used to configure a mutual TLS channel. It is
ignored if ``channel`` or ``ssl_channel_credentials`` is provided.
quota_project_id (Optional[str]): An optional project to use for billing
and quota.
client_info (google.api_core.gapic_v1.client_info.ClientInfo):
The client info used to send a user-agent string along with
API requests. If ``None``, then default info will be used.
Generally, you only need to set this if you're developing
your own client library.
always_use_jwt_access (Optional[bool]): Whether self signed JWT should
be used for service account credentials.
Raises:
google.auth.exceptions.MutualTLSChannelError: If mutual TLS transport
creation failed for any reason.
google.api_core.exceptions.DuplicateCredentialArgs: If both ``credentials``
and ``credentials_file`` are passed.
