Client(
    batch_settings: Union[google.cloud.pubsub_v1.types.BatchSettings, Sequence] = (),
    publisher_options: Union[
        google.cloud.pubsub_v1.types.PublisherOptions, Sequence
    ] = (),
    **kwargs: Any
)

A publisher client for Google Cloud Pub/Sub.

This creates an object that is capable of publishing messages. Generally, you can instantiate this client with no arguments, and you get sensible defaults.

Inheritance

builtins.object > google.pubsub_v1.services.publisher.client.PublisherClient > Client

Properties

api

The underlying gapic API client.

.. versionchanged:: 2.10.0 Instead of a GAPIC PublisherClient client instance, this property is a proxy object to it with the same interface.

deprecated: Use the GAPIC methods and properties on the client instance directly instead of through the api attribute.

target

Return the target (where the API is).

transport

Returns the transport used by the client instance.

Returns

Type	Description
PublisherTransport	The transport used by the client instance.

Methods

Client

Client(
    batch_settings: Union[google.cloud.pubsub_v1.types.BatchSettings, Sequence] = (),
    publisher_options: Union[
        google.cloud.pubsub_v1.types.PublisherOptions, Sequence
    ] = (),
    **kwargs: Any
)

Instantiates the publisher client.

Parameters

Name	Description
credentials	Optional[google.auth.credentials.Credentials] The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
transport	Union[str, PublisherTransport] The transport to use. If set to None, a transport is chosen automatically.
client_options	google.api_core.client_options.ClientOptions Custom options for the client. It won't take effect if a transport instance is provided. (1) The api_endpoint property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the api_endpoint property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the client_cert_source property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.
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.

Exceptions

Type	Description
google.auth.exceptions.MutualTLSChannelError	If mutual TLS transport creation failed for any reason.

__exit__

__exit__(type, value, traceback)

Releases underlying transport's resources.

Warning: ONLY use as a context manager if the transport is NOT shared with other clients! Exiting the with block will CLOSE the transport and may cause errors in other clients!

common_billing_account_path

common_billing_account_path(billing_account: str)

Returns a fully-qualified billing_account string.

common_folder_path

common_folder_path(folder: str)

Returns a fully-qualified location string.

common_organization_path

Description

`.policy_pb2.Policy`

Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A ``Policy`` is a collection of ``bindings``. A ``binding`` binds one or more ``members`` to a single ``role``. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A ``role`` is a named list of permissions (defined by IAM or configured by users). A ``binding`` can optionally specify a ``condition``, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource. **JSON Example**:: { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:[e-mail]", "group:[e-mail]", "domain:google.com", "serviceAccount:[e-mail]" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": ["user:[e-mail]"], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01t00:00:00.000z')",="" }="" }="" ]="" }="" **yaml="" example**::="" bindings:="" -="" members:="" -="" user:[e-mail]="" -="" group:[e-mail]="" -="" domain:google.com="" -="" serviceaccount:[e-mail]="" role:="" roles/resourcemanager.organizationadmin="" -="" members:="" -="" user:[e-mail]="" role:="" roles/resourcemanager.organizationviewer="" condition:="" title:="" expirable="" access="" description:="" does="" not="" grant="" access="" after="" sep="" 2020="" expression:="" request.time="">< timestamp('2020-10-01t00:00:00.000z')="" for="" a="" description="" of="" iam="" and="" its="" features,="" see="" the="" `iam="" developer's="" guide="">

get_mtls_endpoint_and_cert_source

get_mtls_endpoint_and_cert_source(
    client_options: Optional[google.api_core.client_options.ClientOptions] = None,
)

Return the API endpoint and client cert source for mutual TLS.

The client cert source is determined in the following order: (1) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not "true", the client cert source is None. (2) if client_options.client_cert_source is provided, use the provided one; if the default client cert source exists, use the default one; otherwise the client cert source is None.

The API endpoint is determined in the following order: (1) if client_options.api_endpoint if provided, use the provided one. (2) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "always", use the default mTLS endpoint; if the environment variabel is "never", use the default API endpoint; otherwise if client cert source exists, use the default mTLS endpoint, otherwise use the default API endpoint.

More details can be found at https://google.aip.dev/auth/4114.

publish

publish(topic: str, data: bytes, ordering_key: str = '', retry: OptionalRetry = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: types.OptionalTimeout = <_MethodDefault._DEFAULT_VALUE: <object object>>, **attrs: Union[bytes, str])

Publish a single message.

Note: Messages in Pub/Sub are blobs of bytes. They are binary data, not text. You must send data as a bytestring (bytes in Python 3; str in Python 2), and this library will raise an exception if you send a text string.

The reason that this is so important (and why we do not try to coerce for you) is because Pub/Sub is also platform independent and there is no way to know how to decode messages properly on the other side; therefore, encoding and decoding is a required exercise for the developer.

Add the given message to this object; this will cause it to be published once the batch either has enough messages or a sufficient period of time has elapsed. This method may block if LimitExceededBehavior.BLOCK is used in the flow control settings.

.. rubric:: Example

from google.cloud import pubsub_v1 client = pubsub_v1.PublisherClient() topic = client.topic_path('[PROJECT]', '[TOPIC]') data = b'The rain in Wales falls mainly on the snails.' response = client.publish(topic, data, username='guido')

Exceptions

Type	Description
RuntimeError	If called after publisher has been stopped by a `stop()` method call.
pubsub_v1.publisher.exceptions.MessageTooLargeError	If publishing the ``message`` would exceed the max size limit on the backend.

resume_publish

resume_publish(topic: str, ordering_key: str)

Resume publish on an ordering key that has had unrecoverable errors.

Exceptions

Type	Description
RuntimeError	If called after publisher has been stopped by a `stop()` method call.
ValueError	If the topic/ordering key combination has not been seen before by this client.

schema_path

schema_path(project: str, schema: str)

Returns a fully-qualified schema string.
