如何使用从RoR应用程序到另一个RoR应用程序的HTTP POST请求来处理AuthenticityToken值？

email

password

pjtnam.com

users.pjtname.com

pjtname.com

users.pjtname.com

response = Typhoeus::Request.post("http://users.pjtname.com/authentications",
             :params => {
               :new_authentication => {
                 :email    => email,
                 :password => password
               }
             }
           )
