How to do a wiredump of XMLRPC::Client in ruby?

Question

I'm working on some code using XML RPC in ruby and need to see some debug info, how do you do that?

Answer 1

Reading the source of the package, XMLRPC::Client uses Net::HTTP in turn as its transport.

So I think you should be able to monkey-patch a method into the XMLRPC::Client accordingly:

require 'pp'

# the magic happens here
class XMLRPC::Client
  def set_debug
    @http.set_debug_output($stderr);
  end
end

server = XMLRPC::Client.new2("http://rpc.technorati.com/rpc/ping")
server.set_debug
result = server.call("weblogUpdates.ping", "Copenhagen.rb", "http://www.copenhagenrb.dk/")
pp result

(sample for XMLRPC snarfed from here).
