Cloud Storage API - Module Google::Cloud::Storage (v1.45.0)

Reference documentation and code samples for the Cloud Storage API module Google::Cloud::Storage.

Google Cloud Storage

Google Cloud Storage is an Internet service to store data in Google's cloud. It allows world-wide storage and retrieval of any amount of data and at any time, taking advantage of Google's own reliable and fast networking infrastructure to perform data operations in a cost effective manner.

See Storage Overview.

Methods

.anonymous

def self.anonymous(retries: nil, timeout: nil, open_timeout: nil, read_timeout: nil, send_timeout: nil, endpoint: nil, max_elapsed_time: nil, base_interval: nil, max_interval: nil, multiplier: nil, upload_chunk_size: nil) -> Google::Cloud::Storage::Project

Creates an unauthenticated, anonymous client for retrieving public data from the Storage service. Each call creates a new connection.

Parameters
  • retries (Integer) (defaults to: nil) — Number of times to retry requests on server error. The default value is 3. Optional.
  • max_elapsed_time (Integer) (defaults to: nil) — Total time in seconds that requests are allowed to keep being retried.
  • base_interval (Float) (defaults to: nil) — The initial interval in seconds between tries.
  • max_interval (Integer) (defaults to: nil) — The maximum interval in seconds that any individual retry can reach.
  • multiplier (Integer) (defaults to: nil) — Each successive interval grows by this factor. A multipler of 1.5 means the next interval will be 1.5x the current interval.
  • timeout (Integer) (defaults to: nil) — (default timeout) The max duration, in seconds, to wait before timing out. Optional. If left blank, the wait will be at most the time permitted by the underlying HTTP/RPC protocol.
  • open_timeout (Integer) (defaults to: nil) — How long, in seconds, before failed connections time out. Optional.
  • read_timeout (Integer) (defaults to: nil) — How long, in seconds, before requests time out. Optional.
  • send_timeout (Integer) (defaults to: nil) — How long, in seconds, before receiving response from server times out. Optional.
  • endpoint (String) (defaults to: nil) — Override of the endpoint host name. Optional. If the param is nil, uses the default endpoint.
  • upload_chunk_size (Integer) (defaults to: nil) — The chunk size of storage upload, in bytes. The default value is 100 MB, i.e. 104_857_600 bytes. To disable chunking and upload the complete file regardless of size, pass 0 as the chunk size.
Returns
Example

Use skip_lookup to avoid retrieving non-public metadata:

require "google/cloud/storage"

storage = Google::Cloud::Storage.anonymous

bucket = storage.bucket "public-bucket", skip_lookup: true
file = bucket.file "path/to/public-file.ext", skip_lookup: true

downloaded = file.download
downloaded.rewind
downloaded.read #=> "Hello world!"

.configure

def self.configure() -> Google::Cloud::Config

Configure the Google Cloud Storage library.

The following Storage configuration parameters are supported:

  • project_id - (String) Identifier for a Storage project. (The parameter project is considered deprecated, but may also be used.)
  • credentials - (String, Hash, Google::Auth::Credentials) The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Credentials) (The parameter keyfile is considered deprecated, but may also be used.)
  • endpoint - (String) Override of the endpoint host name, or nil to use the default endpoint.
  • scope - (String, Array
  • retries - (Integer) Number of times to retry requests on server error.
  • max_elapsed_time - (Integer) Total time in seconds that requests are allowed to keep being retried.
  • base_interval - (Float) The initial interval in seconds between tries.
  • max_interval - (Integer) The maximum interval in seconds that any individual retry can reach.
  • multiplier - (Integer) Each successive interval grows by this factor. A multipler of 1.5 means the next interval will be 1.5x the current interval.
  • timeout - (Integer) (default timeout) The max duration, in seconds, to wait before timing out. If left blank, the wait will be at most the time permitted by the underlying HTTP/RPC protocol.
  • open_timeout - (Integer) How long, in seconds, before failed connections time out.
  • read_timeout - (Integer) How long, in seconds, before requests time out.
  • send_timeout - (Integer) How long, in seconds, before receiving response from server times out.
  • upload_chunk_size - (Integer) The chunk size of storage upload, in bytes.
Yields
  • (Google::Cloud.configure.storage)
Returns
  • (Google::Cloud::Config) — The configuration object the Google::Cloud::Storage library uses.

.new

def self.new(project_id: nil, credentials: nil, scope: nil, retries: nil, timeout: nil, open_timeout: nil, read_timeout: nil, send_timeout: nil, endpoint: nil, project: nil, keyfile: nil, max_elapsed_time: nil, base_interval: nil, max_interval: nil, multiplier: nil, upload_chunk_size: nil) -> Google::Cloud::Storage::Project

Creates a new object for connecting to the Storage service. Each call creates a new connection.

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

Parameters
  • project_id (String) (defaults to: nil) — Project identifier for the Storage 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 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/devstorage.full_control
  • retries (Integer) (defaults to: nil) — Number of times to retry requests on server error. The default value is 3. Optional.
