dRuby client/server mode sample program
By: Emiley J. in Ruby Tutorials on 2009-03-03
This illustrates setting up a simple client-server drb system. Run the server and client code in different terminals, starting the server code first.
Server code
require 'drb/drb'
# The URI for the server to connect to
URI="druby://localhost:8787"
class TimeServer
def get_current_time
return Time.now
end
end
# The object that handles requests on the server
FRONT_OBJECT=TimeServer.new
$SAFE = 1 # disable eval() and friends
DRb.start_service(URI, FRONT_OBJECT)
# Wait for the drb server thread to finish before exiting.
DRb.thread.join
Client code
require 'drb/drb' # The URI to connect to SERVER_URI="druby://localhost:8787" # Start a local DRbServer to handle callbacks. # # Not necessary for this small example, but will be required # as soon as we pass a non-marshallable object as an argument # to a dRuby call. DRb.start_service timeserver = DRbObject.new_with_uri(SERVER_URI) puts timeserver.get_current_time
