Rails has native support for xmlrpc. Most people are familiar with the 'xmlrpc/client' library. The 'xmlrpc/server' library examples mostly make an assumption that you will run a standalone server.
rails-xmlrpc allows you to instead expose normal Rails controller methods via XMLRPC, tied to an xmlrpc endpoint route in your app.
Run in terminal:
gem install rails-xmlrpc
For Rails 2
Add row to environment.rb inside Rails::Initializer block:
Add row to routes.rb
map.connect 'api/xmlrpc', :controller => 'my_controller', :action => 'xe_index'
For Rails 3
Add row to Gemfile:
Set up a route in your routes.rb file
match 'api/xmlrpc' => 'my#xe_index'
Add this code to your controller:
class MyController < ApplicationController exposes_xmlrpc_methods add_method 'Container.method_name' do 'Hello World' end end
Then, pointing an XMLRPC client at the defined route, your normal controller actions will handle the requests.
require 'xmlrpc/client' server = XMLRPC::Client.new2("http://localhost:3000/api/xmlrpc") server.call("Container.method_name")
To use a custom namespace prefix on all exposed methods (for example, if using someone else's specified protocol like MetaWeblog), declare a method_prefix:
class MyApiController < ApplicationController exposes_xmlrpc_methods :method_prefix => "metaWeblog." # This method will be exposed externally as "metaWeblog.newPost()" def newPost(blogid, username, password, struct, publish) ... end end
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
