Implements XML-RPC client support
Example Usage
class BloggerAPI < ActionWebService::API::Base inflect_names false api_method :getRecentPosts, :returns => [[Blog::Post]] end blog = ActionWebService::Client::XmlRpc.new(BloggerAPI, "http://.../RPC", :handler_name => "blogger") posts = blog.getRecentPosts
Methods
Public Class methods
Creates a new web service client using the XML-RPC protocol.
api must be an ActionWebService::API::Base derivative, and endpoint_uri must point at the relevant URL to which protocol requests will be sent with HTTP POST.
Valid options:
- :handler_name
- If the remote server defines its services inside special handler (the Blogger API uses a "blogger" handler name for example), provide it here, or your method calls will fail
