Question

Retrieving XRDS document in OpenID using Ruby

Answer 1

+1 A:

Google expects the https protocol, though in your ruby example you use http, hence the 302 error. The following snippet should get you the xrds document:

require 'net/http'
require 'net/https'
require 'uri'

uri = URI.parse('https://www.google.com/accounts/o8/id')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
puts "#{response.read_body}"

Answer 2

+1 A:

As you can see, when you fetch the document from ruby, it returns 302 status code, which means that you should look for location header and follow it, like curl does.

Another answer suggested just hardcoding the valid url, but that isn't a correct solution, since Google could make it return 302 as well and move the document somewhere else.

Not to mention that you should perform full Yadis discovery instead of hoping that you'll get an XRDS document from the url (because, for example, Google might decide that it's a good location for explanation of OpenID, and move the XRDS somewhere else using X-XRDS-Location header).
