RUBY 实现SOAP

SOAP 服务端：
#!/usr/local/bin/ruby
require 'soap/rpc/standaloneServer'
module MySOAP
 class Timer
  def now
   Time.new.strftime("%Y-%m-%d %H:%M:%S")
  end
 end
 class Add
   def add(i, j)
  return i.to_i + j.to_i
   end
 end
end
class TimeServer < SOAP::RPC::StandaloneServer
 def on_init
  time = MySOAP::Timer.new
  add = MySOAP::Add.new
  add_method(time,"now")
  add_method(add,"add")
 end
end
NS = 'http://localhost/soap'
port = 4000
svr = TimeServer.new('timer',NS,'0.0.0.0',port)
trap('INT') { svr.shutdown }
puts "My SOAP is starting... port:#{port} (Ctrl+c to quit)"
svr.start
puts "My SOAP is stop."
SOAP客户端：
require 'soap/rpc/driver'
proxy = SOAP::RPC::Driver.new("http://localhost:4000","http://localhost/soap")
proxy.add_method('now')
proxy.add_method('add','i','j')
puts "Server time now is : #{proxy.now}"
puts "9 + 2000 = #{proxy.add(9,2000)}"
