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？我试过快速入门指南，但失败了

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

有0个答案的类似问题：

好的，我找到了一种方法

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在像Heroku这样的临时文件系统中工作，并将令牌存储在数据库中。

对于仍在寻找的人，这对我来说是有效的：

require 'google/apis/calendar_v3'
require 'googleauth'

scope = 'https://www.googleapis.com/auth/calendar'

authorizer = Google::Auth::ServiceAccountCredentials.make_creds(
  json_key_io: File.open('/path/to/creds.json'),
  scope: scope)

authorizer.fetch_access_token!

service = Google::Apis::CalendarV3::CalendarService.new
service.authorization = authorizer

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

诀窍是为GoogleAuth库ruby查找文档
