Override VCR's :body matcher to ignore order

spec_helper.rb

VCR.configure do |c|
  # Since HTTParty takes a Hash of body data, we can never be sure that it is
  # sent in the same order. This can cause VCR to not recognize the request and
  # therefore not use a previously recorded response.
  # This overrides VCR's built-in :body matcher to ignore the order of the data
  c.register_request_matcher :body do |request1, request2|
    body1 = request1.body.split('&')
    body2 = request2.body.split('&')
    (body1 - body2).empty?
  end
end
