Overview

Implements a standalone XML-RPC server. The method #serve is left if a SIGHUP is sent to the program.

 require "xmlrpc/server"

s = XMLRPC::Server.new(8080)

s.add_handler("michael.add") do |a,b|
  a + b
end

s.add_handler("michael.div") do |a,b|
  if b == 0
    raise XMLRPC::FaultException.new(1, "division by zero")
  else
    a / b
  end
end

s.set_default_handler do |name, *args|
  raise XMLRPC::FaultException.new(-99, "Method #{name} missing" +
                                   " or wrong number of parameters!")
end

s.serve

Constructor Details

.new(port = 8080, host = "127.0.0.1", maxConnections = 4, stdlog = $stdout, audit = true, debug = true, *a) ⇒ Server

Creates a new Server instance, which is a XML-RPC server listening on the given port and accepts requests for the given host, which is localhost by default.

The server is not started, to start it you have to call #serve.

The optional audit and debug parameters are obsolete!

All additionally provided parameters in *a are by-passed to BasicServer.new.
