Raw HTTP Request/Response

Since all request/response is via SSL, you can’t use usual TCP tracking tools like tcpflow.
If you need to do so, this code will help you.

In this code,

• method is RPC method (SetExpressCheckout etc.), not HTTP method.
• params is request body parameters except for METHOD parameter.
• response is response body parameters.

module Paypal
  module NVP
    module Debugger
      def post(method, params = {})
        response = super
        puts <<-DEBUG
#{method}
==========
#{params.to_query}
----------
#{response}
==========

DEBUG
        response
      end
    end

    class Request
      prepend Debugger
    end
  end
end
