Rails Google API клиент нагрузки P12 метод файл/JSON

Question

После образца, который находится здесь: https://gist.github.com/joost/5344705

последняя версия google-api-client жемчужину бросает ошибку на:

key = Google::APIClient::PKCS12.load_key(key_file, 'notasecret') 
#=> Uninitialized constant Google::APIClient(name error) 

Что новый метод загрузите файл P12/JSON?

FYI, переработан подверженной ошибкам код:

# you need to set this according to your situation/needs 
SERVICE_ACCOUNT_EMAIL_ADDRESS = 'xxx@developer.gserviceaccount.com' # looks like 12345@developer.gserviceaccount.com 
PATH_TO_KEY_FILE    = '/home/arjun/rails/learn/xxx.p12' # the path to the downloaded .p12 key file 
PROFILE      = 'ga:xxx' # your GA profile id, looks like 'ga:12345' 


require 'google/apis/analytics_v3' 
require 'googleauth/stores/file_token_store' 

Analytics = Google::Apis::AnalyticsV3 
# set up a client instance 
client = Analytics::AnalyticsService.new 

client.authorization = Signet::OAuth2::Client.new(
    :token_credential_uri => 'https://accounts.google.com/o/oauth2/token', 
    :audience    => 'https://accounts.google.com/o/oauth2/token', 
    :scope    => 'https://www.googleapis.com/auth/analytics.readonly', 
    :issuer    => SERVICE_ACCOUNT_EMAIL_ADDRESS, 
    # :signing_key   => OpenSSL::PKey.load_key(PATH_TO_KEY_FILE, 'notasecret') 

    # Not working = throws []': no implicit conversion of Symbol into Integer (TypeError) 
    :signing_key   => Google::Auth::Stores::FileTokenStore.new(PATH_TO_KEY_FILE.to_i) 
).tap { |auth| auth.fetch_access_token! } 

api_method = client.discovered_api('analytics','v3').data.ga.get 


# make queries 
result = client.execute(:api_method => api_method, :parameters => { 
    'ids'  => PROILE, 
    'start-date' => Date.new(1970,1,1).to_s, 
    'end-date' => Date.today.to_s, 
    'dimensions' => 'ga:pagePath', 
    'metrics' => 'ga:pageviews', 
    'filters' => 'ga:pagePath==/url/to/user' 
}) 

puts result.data.rows.inspect

для версии 0.9.18 в google-api-client драгоценный камень, то signing_key часть должна измениться на:

require 'google/api_client/auth/key_utils'

signing_key: Google::APIClient::KeyUtils::load_from_pkcs12(keypath, 'notasecret')
