Class Method Details

.from_access_token(access_token, client_options = nil, request_options = nil) ⇒ Object

Constructs a GoogleDrive::Session object from OAuth2 access token string.

See from_config documentation for an explanation of client_options and request_options.

66
# File 'lib/google_drive/session.rb', line 64

def self.from_access_token(access_token, client_options = nil, request_options = nil)
  Session.new(access_token, nil, client_options, request_options)
end

.from_config(config, options = {}) ⇒ Object

Returns GoogleDrive::Session constructed from a config JSON file at config, potenially modified with options.

config is the path to the config file.

This will prompt the credential via command line for the first time and save it to config for later usages.

See github.com/gimite/google-drive-ruby/blob/master/doc/authorization.md for a usage example.

You can also provide a config object that must respond to:

client_id
client_secret
refesh_token
refresh_token=
scope
scope=
save

options is a hash which may contain the following keys:

client_secret: if present, this will overwrite config.client_secret
client_id: if present, this will overwrite config.client_id
client_options: a hash or ::Google::Apis::ClientOptions. See
  https://www.rubydoc.info/github/google/google-api-ruby-client/Google/Apis/ClientOptions
  for an explanation of legal sub-fields.
request_options: a hash or ::Google::Apis::RequestOptions. See
  https://www.rubydoc.info/github/google/google-api-ruby-client/Google/Apis/RequestOptions
  for an explanation of legal sub-fields.

.from_credentials(credentials, client_options = nil, request_options = nil) ⇒ Object

Constructs a GoogleDrive::Session object from OAuth2 credentials such as Google::Auth::UserRefreshCredentials.

See github.com/gimite/google-drive-ruby/blob/master/doc/authorization.md for a usage example.

See from_config documentation for an explanation of client_options and request_options.

.from_service_account_key(json_key_path_or_io, scope = DEFAULT_SCOPE, client_options = nil, request_options = nil) ⇒ Object

Constructs a GoogleDrive::Session object from a service account key JSON.

You can pass either the path to a JSON file, or an IO-like object with the JSON.

See github.com/gimite/google-drive-ruby/blob/master/doc/authorization.md for a usage example.

As with from_config, you can configure Google API client behavior with client_options and request_options. Unlike in from_config, these are passed as positional arguments.
