Here is my post on how to make a https call. http://srikanthjeeva.blogspot.in/2010/06/making-httphttps-post-request.html
Spent a long time in figuring out how to send a https request under a proxy
Here is how it is,
require 'net/http'
require 'net/https'
require 'uri'
uri = URI('https://IP/api/V1/USERS')
proxy_class = Net::HTTP::Proxy(PROXY_ADDRESS, PROXY_PORT, USERNAME, PASSWORD)
proxy_class.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https', :verify_mode => OpenSSL::SSL::VERIFY_NONE) { |http|
request = Net::HTTP::Get.new uri.request_uri
response = http.request request
puts response.body
}
Hope this helps.
Thanks!
