does not exist. The message payload must not be empty; it must contain
either a non-empty data field, or at least one attribute.
Example:
>>> from google.cloud.gapic.pubsub.v1.publisher_api import PublisherApi
>>> from google.pubsub.v1 import pubsub_pb2
>>> api = PublisherApi()
>>> topic = api.topic_path('[PROJECT]', '[TOPIC]')
>>> data = ''
>>> messages_element = pubsub_pb2.PubsubMessage(data)
>>> messages = [messages_element]
>>> response = api.publish(topic, messages)
Args:
topic (string): The messages in the request will be published on this topic.
messages (list[:class:`google.pubsub.v1.pubsub_pb2.PubsubMessage`]): The messages to publish.
options (:class:`google.gax.CallOptions`): Overrides the default
settings for this call, e.g, timeout, retries etc.
Returns:
A :class:`google.pubsub.v1.pubsub_pb2.PublishResponse` instance.
Raises:
:exc:`google.gax.errors.GaxError` if the RPC is aborted.
