Rails没有bitizeize错误到第三方API响应

Question

I have a rails app and I'm trying to get calendar freebusy events from google. When I run the following code I get undefined method "bytesize" for #<Hash.. error for the result = client.execute(.... method. I checked out some other stackoverflow answers, but I can't see what I'm doing wrong. Anyone can tell me how I should deal with this problem?

controller

  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

From Pardeep's link, try

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'})

The problem is that the body could not be sent as a hash. You should encode as an string.
