Rails Controller for the Meraki Presence API. You need to generate a models for saving these into the database via: rails generate model presence ap_mac:string client_mac:string last_seen:datetime rssi:integer

meraki_controller.rb

# 1. Generate a model Presence before:
# rails generate model presence ap_mac:string client_mac:string last_seen:datetime rssi:integer
#
# 2. Add a route:
#   match 'meraki', :to => 'meraki#presenceapi', :as => :meraki
#
# 3. Test this controller via:
# curl -d data="{\"secret\":\"foobar\",\"probing\":[{\"ap_mac\":\"00:aa:bb:cc:dd:ee\",\"client_mac\":\"ff:ee:dd:cc:bb:aa\",\"last_seen\":\"Wed Jan 22 08:34:02.409 UTC 2014\",\"rssi\":\"16\"},{\"ap_mac\":\"11:22:33:44:55:66\",\"client_mac\":\"99:88:77:66:55:44\",\"last_seen\":\"Wed Jan 22 08:34:06.409 UTC 2014\",\"rssi\":\"29\"}]}" https://localhost:3000/meraki
#
# 4. Point Meraki to https://my.app.name/presenceapi

MERAKI_VALIDATOR = '12345'
MERAKI_SECRET = 'foobar'

class MerakiController < ApplicationController

  skip_before_filter :verify_authenticity_token

  def presenceapi
    if request.post?
      map = JSON.parse(params[:data]).with_indifferent_access
      if map[:secret] == MERAKI_SECRET
        map[:probing].each do |p|
          Presence.create(ap_mac: p[:ap_mac], client_mac: p[:client_mac],
                          last_seen: DateTime.parse(p[:last_seen]),
                          rssi: p[:rssi])
        end
        render :text => '' and return
      else
        Rails::logger.warn("*** Meraki req with bad secret '#{map[:secret]}'")
        raise 'access denied'
      end
    else
      render :text => MERAKI_VALIDATOR
    end
  end
