如何在Ruby中为Google Calendar API授权服务帐户？

如何在Ruby中为Google Calendar API授权服务帐户？ 我尝试了快速入门指南，但它崩溃了。

https://developers.google.com/calendar/quickstart/ruby#step_3_set_up_the_sample

quickstart.rb

 require 'google/apis/calendar_v3' require 'googleauth' require 'googleauth/stores/file_token_store' require 'fileutils' OOB_URI = 'urn:ietf:wg:oauth:2.0:oob'.freeze APPLICATION_NAME = 'Google Calendar API Ruby Quickstart'.freeze CLIENT_SECRETS_PATH = 'client_secrets.json'.freeze CREDENTIALS_PATH = 'token.yaml'.freeze SCOPE = Google::Apis::CalendarV3::AUTH_CALENDAR_READONLY ## # Ensure valid credentials, either by restoring from the saved credentials # files or intitiating an OAuth2 authorization. If authorization is required, # the user's default browser will be launched to approve the request. # # @return [Google::Auth::UserRefreshCredentials] OAuth2 credentials def authorize client_id = Google::Auth::ClientId.from_file(CLIENT_SECRETS_PATH) ### LINE 19 token_store = Google::Auth::Stores::FileTokenStore.new(file: CREDENTIALS_PATH) authorizer = Google::Auth::UserAuthorizer.new(client_id, SCOPE, token_store) user_id = 'default' credentials = authorizer.get_credentials(user_id) if credentials.nil? url = authorizer.get_authorization_url(base_url: OOB_URI) puts 'Open the following URL in the browser and enter the ' \ 'resulting code after authorization:\n' + url code = gets credentials = authorizer.get_and_store_credentials_from_code( user_id: user_id, code: code, base_url: OOB_URI ) end credentials end # Initialize the API service = Google::Apis::CalendarV3::CalendarService.new service.client_options.application_name = APPLICATION_NAME service.authorization = authorize # Fetch the next 10 events for the user calendar_id = 'primary' response = service.list_events(calendar_id, max_results: 10, single_events: true, order_by: 'startTime', time_min: Time.now.iso8601) puts 'Upcoming events:' puts 'No upcoming events found' if response.items.empty? response.items.each do |event| start = event.start.date || event.start.date_time puts "- #{event.summary} (#{start})" end 

Console

 >ruby quickstart.rb C:/ruby23/lib/ruby/gems/2.3.0/gems/googleauth-0.6.2/lib/googleauth/client_id.rb:97:in `from_hash': Expected top level property 'installed' or 'web' to be present. (RuntimeError) from C:/ruby23/lib/ruby/gems/2.3.0/gems/googleauth-0.6.2/lib/googleauth/client_id.rb:83:in `block in from_file' from C:/ruby23/lib/ruby/gems/2.3.0/gems/googleauth-0.6.2/lib/googleauth/client_id.rb:80:in `open' from C:/ruby23/lib/ruby/gems/2.3.0/gems/googleauth-0.6.2/lib/googleauth/client_id.rb:80:in `from_file' from quickstart.rb:19:in `authorize' from quickstart.rb:39:in `' 

用于授权服务帐户的（过时的）文档仅包含Java和Python的示例。

好的，我找到了办法。

https://developers.google.com/api-client-library/ruby/auth/service-accounts

 require 'google/apis/calendar_v3' require 'googleauth' # Get the environment configured authorization scopes = ['https://www.googleapis.com/auth/calendar'] authorization = Google::Auth.get_application_default(scopes) # Clone and set the subject auth_client = authorization.dup auth_client.sub = '[e-mail]' auth_client.fetch_access_token! # Initialize the API service = Google::Apis::CalendarV3::CalendarService.new service.authorization = auth_client # Fetch the next 10 events for the user calendar_id = 'primary' response = service.list_events(calendar_id, max_results: 10, single_events: true, order_by: 'startTime', time_min: Time.now.iso8601) puts 'Upcoming events:' puts 'No upcoming events found' if response.items.empty? response.items.each do |event| start = event.start.date || event.start.date_time puts "- #{event.summary} (#{start})" end 

和

 >set GOOGLE_APPLICATION_CREDENTIALS=client_secrets.json C:\Users\Chloe\workspace>ruby quickstart.rb Upcoming events: - Test (2018-05-17) - SSL Certificate for CMS (2019-02-13) 

但我想知道它在哪里保存刷新令牌和访问令牌？ 我现在要做的就是让它适用于像Heroku这样的短暂文件系统，并将令牌存储在数据库中。
