【问题描述】：

我有一个 Rails 应用程序，我正在尝试从谷歌获取日历空闲事件。当我运行以下代码时，result = client.execute(.... 方法出现 undefined method "bytesize" for #<Hash.. 错误。我检查了其他一些 stackoverflow 答案，但我看不出我做错了什么。谁能告诉我应该如何处理这个问题？

控制器

  include GoogleCalendarApi
  ......
  @user = current_user
    @google = @user.socials.where(provider: "google_oauth2").first
    unless @google.blank?
      # @client = get_busy_events(@google)
      # @result = open_gcal_connection(get_busy_events, @client, @google)
      @result = get_busy_events(@google)
    end
    .....

lib/google_calendar_api.rb

def init_google_api_calendar_client(google_account)
  #method only called if google_oauth2 social exists
  client = Google::APIClient.new
  client.authorization.access_token = google_account.token
  client.authorization.client_id = ENV['GOOGLE_API_KEY']
  client.authorization.client_secret = ENV['GOOGLE_API_SECRET']
  client.authorization.refresh_token = google_account.refresh_token
  return client
end

def get_busy_events(social_object)
  client = init_google_api_calendar_client(social_object)
  old_token = client.authorization.access_token
  service = client.discovered_api('calendar', 'v3')

  result = client.execute(
    api_method: service.freebusy.query,
    body: { timeMin: '2015-12-24T17:06:02.000Z',
            timeMax: '2016-01-30T17:06:02.000Z',
            items: [{ id: social_object.email }]},
   headers: {'Content-Type' => 'application/json'})

   new_token = client.authorization.access_token
   if old_token != new_token
    social_object.update_attribute(token: new_token)
   end

  return result
end

完全错误：

【问题讨论】：

你也可以发布完整的错误跟踪吗？
qubit，我编辑了代码。响应实际上更长，但我想这就是你需要的。
这可能会有所帮助stackoverflow.com/questions/21799817/…
Pardeep，我读过这篇文章，但无法理解。你能告诉我在我的情况下应该如何应用它吗？

标签： ruby-on-rails json api

【解决方案1】：

从 Pardeep 的链接，试试

result = client.execute(
    api_method: service.freebusy.query,
    body: URI.encode_www_form({ timeMin: '2015-12-24T17:06:02.000Z',
            timeMax: '2016-01-30T17:06:02.000Z',
            items: [{ id: social_object.email }]}),
   headers: {'Content-Type' => 'application/json'})

问题是正文无法作为散列发送。您应该编码为字符串。
