Export Order Email Addresses From Magento w/Ruby

You need to setup a web services user beforehand for this to work. Install the Savon gem, and get your endpoint url and credentials. This uses the SOAP v2 interface on Magento.

requre  'rubygems'
require 'savon'
client = Savon::Client.new "https://<Your Endpoint>"

res = client.request :login do 
 soap.body = {:username => '<your soap user>', :apiKey => '<your key>'}
end
session = res[:login_response][:login_return]
res2 = client.request :salesOrderList do
 soap.body = {:session=>session}
end
b = res2[:sales_order_list_response][:result][:item]
b.each do |ord|
 puts ord[:order_id] + ":" + ord[:customer_email]
end
