.pubsub(project_id = nil, credentials = nil, scope: nil, timeout: nil) ⇒ Google::Cloud::PubSub::Project

Creates a new object for connecting to the Pub/Sub service. Each call creates a new connection.

For more information on connecting to Google Cloud see the Authentication Guide.

topic = pubsub.topic "my-topic"
topic.publish "task completed"

Parameters:

  • project_id (String) (defaults to: nil) —

    Project identifier for the Pub/Sub service you are connecting to. If not present, the default project for the credentials is used.

  • credentials (String, Hash, Google::Auth::Credentials) (defaults to: nil) —

    The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Google::Cloud::PubSub::Credentials)

  • scope (String, Array<String>) (defaults to: nil) —

    The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs.

    The default scope is:

    • https://www.googleapis.com/auth/pubsub
