ruby-on-rails - Google Calendar API 插入方法不适用于 Ruby

问题描述

我正在尝试在我的 Ruby 项目中使用 Google Calendar API，但在尝试使用 API 中的插入时遇到了问题。当我在https://developers.google.com/calendar/v3/reference/events/insert#examples上尝试示例代码时，我最终得到了一个错误。

insertEvent.rb:2:in `<main>': uninitialized constant Google (NameError)

如果我将此示例代码粘贴在此页面 https://developers.google.com/calendar/quickstart/ruby上的 quickstart.rb 之后，我将收到此错误：

quickstart.rb:84:in `<main>': undefined local variable or method `client' for main:Object (NameError)

谷歌在这里没有给我客户端变量的定义，所以我没有在这里插入什么。我是 Ruby 的新手，非常感谢您的帮助。

这是我陷入的代码

result = client.insert_event('primary', event)
puts "Event created: #{result.html_link}"

标签： ruby-on-railsruby

解决方案

是的，客户没有定义。试试这个示例代码

https://github.com/googleapis/google-api-ruby-client/blob/master/samples/cli/lib/samples/calendar.rb

和

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

这里的重要部分：

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
CREDENTIALS_PATH = 'credentials.json'.freeze
TOKEN_PATH = 'token.yaml'.freeze
SCOPE = Google::Apis::CalendarV3::AUTH_CALENDAR_READONLY

def authorize
  client_id = Google::Auth::ClientId.from_file(CREDENTIALS_PATH)
  token_store = Google::Auth::Stores::FileTokenStore.new(file: TOKEN_PATH)
  authorizer = Google::Auth::UserAuthorizer.new(client_id, SCOPE, token_store)

  # figure out your user_id
  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

calendar = Google::Apis::CalendarV3::CalendarService.new
calendar.client_options.application_name = APPLICATION_NAME
calendar.authorization = authorize

event = {
  summary: 'Events',
  attendees: [
    {email: 'lpage@example.com'},
    {email: 'sbrin@example.com'},
  ],
  start: {
    date_time: '2015-05-28T09:00:00-07:00',
    time_zone: 'America/Los_Angeles',
  },
  end: {
    date_time: '2015-05-28T17:00:00-07:00',
    time_zone: 'America/Los_Angeles',
  }
}

event = calendar.insert_event('primary', event, send_notifications: true)

并且不要忘记先运行它：

gem install google-api-client

并使用正确的身份验证信息创建这些文件

  1. credentials.json
  2. token.yaml

并找出你的user_id.
