Class Method Summary

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

  Creates a new object for connecting to the Pub/Sub service.

Instance Method Summary

• #pubsub(scope: nil, timeout: nil, client_config: nil) ⇒ Google::Cloud::Pubsub::Project

  Creates a new object for connecting to the Pub/Sub service.

Class Method Details

.pubsub(project_id = nil, credentials = nil, scope: nil, timeout: nil, client_config: 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.

Examples:

require "google/cloud"

pubsub = Google::Cloud.pubsub

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>) —

  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
• timeout (Integer) —

  Default timeout to use in requests. Optional.

• client_config (Hash) —

  A hash of values to override the default behavior of the API client. Optional.

Returns:

• (Google::Cloud::Pubsub::Project)
