Cloud Pub/Sub API - Module Google::Cloud (v3.0.3)

Reference documentation and code samples for the Cloud Pub/Sub API module Google::Cloud.

Methods

.pubsub

def self.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.

Parameters
  • project_id (String) — Project identifier for the Pub/Sub service you are connecting to. If not present, the default project for the credentials is used.
  • credentials (Google::Auth::Credentials) — A Google::Auth::Credentials object. (See PubSub::Credentials) @note Warning: Passing a String to a keyfile path or a Hash of credentials is deprecated. Providing an unvalidated credential configuration to Google APIs can compromise the security of your systems and data.

    @example

    # The recommended way to provide credentials is to use the make_creds method # on the appropriate credentials class for your environment.

    require "googleauth"

    credentials = ::Google::Auth::ServiceAccountCredentials.make_creds( json_key_io: ::File.open("/path/to/keyfile.json") )

    pubsub = Google::Cloud::Pubsub.new project_id: "my-project", credentials: 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
  • timeout (Numeric) (defaults to: nil) — Default timeout to use in requests. Optional.
Returns
Example 
require "google/cloud"

pubsub = Google::Cloud.pubsub

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