在Ruby中通过UPnP打开路由器端口

gem install upnp

require 'upnp'

upnp = UPnP::SSDP.new
upnp.discover

upnp.each_device do |device|
  if device.friendly_name =~ /InternetGatewayDevice/
    device.services.each do |service|
      if service.service_type =~ /WANIPConnection/
        service.actions.each do |action|
          if action.name == 'AddPortMapping'
            action.arguments.each do |argument|
              if argument.name == 'NewLeaseDuration'
                argument.value = 0
              end
            end
            action.invoke(
              'NewRemoteHost' => '',
              'NewExternalPort' => 8080,
              'NewProtocol' => 'TCP',
              'NewInternalClient' => '192.168.1.2',
              'NewInternalPort' => 8080,
              'NewEnabled' => 1,
              'NewPortMappingDescription' => 'Ruby UPnP Example',
              'NewLeaseDuration' => 0
            )
          end
        end
