Credentials matching the Google Calendar API Python quickstart

[cwant]

Hi there,

I'm trying to rework a script from back in the OOB auth days.
I noticed that there is a python calendar quickstart that is very similar to the activities I'd like to perform.

https://developers.google.com/workspace/calendar/api/quickstart/python?hl=en

It works great out of the box using a JSON file with credentials for a "Desktop App".

Can I use this credentials JSON file with one of the auth classes that come with this Ruby library? If so, how?

Thanks,
Chris

It seems what I'm looking for is here:

https://github.com/googleapis/google-api-ruby-client/blob/main/docs/oauth-installed.md

Aw shoot, this points to 5 year old documentation using OOB.

Please don't tell me that this stuff works with Python but has been disabled for Ruby?

Actually the InstalledAppFlow example from the link above does work very much like the python example.

Sorry for the noise.

So this is a similar example to the python one (in this case, just listing from drive).

I hope it helps the next person (and I hope somebody might have suggestions in case of defects):

require 'google/api_client/client_secrets'
require 'google/api_client/auth/installed_app'
require 'google/api_client/auth/storages/file_store'
require 'google/api_client/auth/storage'

require 'google/apis/drive_v2'

TOKEN_FILE = 'token5.json'
SECRETS_FILE = 'client_secrets.json'

token_store = Google::APIClient::FileStore.new(TOKEN_FILE)
storage = Google::APIClient::Storage.new(token_store)
storage.authorize
authorization = storage.authorization

if (!authorization || authorization.expired?)
  client_secrets = Google::APIClient::ClientSecrets.load(SECRETS_FILE)
  flow = Google::APIClient::InstalledAppFlow.new(
    :client_id => client_secrets.client_id,
    :client_secret => client_secrets.client_secret,
    :scope => 'https://www.googleapis.com/auth/drive.metadata.readonly',
    :port => 5000)

  authorization = flow.authorize(storage)
end

drive = Google::Apis::DriveV2::DriveService.new
drive.authorization = authorization
files = drive.list_files

files.items.each do |file|
  puts file.title
end

See the linked python tutorial above about how to get the client secrets file.
