[英]How do I use the Google Calendar API client library for Ruby to get a list of calendar IDs for only my account?
[英]How do I authorize a service account for Google Calendar API in Ruby?
如何在Ruby中為Google Calendar API授權服務帳戶? 我嘗試了快速入門指南,但是崩潰了。
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

相似的老問題有0個答案: 使用服務帳戶在Ruby中使用Google Calendar API
好吧,我找到了辦法。
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 = 'myemail@mydomain.com'
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)
但是我不知道它在哪里保存刷新令牌和訪問令牌? 我現在要做的就是使它適用於像Heroku這樣的臨時文件系統,並將令牌存儲在數據庫中。
對於仍在尋找的人,這對我有用:
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
訣竅是找到google-auth-library-ruby https://github.com/googleapis/google-auth-library-ruby的文檔
