如何在Ruby中读取UDP广播数据报

require 'socket'

# 创建UDP Socket
socket = UDPSocket.new

# 绑定本地IP和端口
socket.bind('0.0.0.0', 1234)

# 设置套接字选项，允许接收广播数据
socket.setsockopt(Socket::SOL_SOCKET, Socket::SO_BROADCAST, true)

# 循环接收数据报
loop do
  # 接收数据报
  data, addr = socket.recvfrom(1024)

  # 处理接收到的数据
  puts "Received data: #{data} from #{addr[3]}:#{addr[1]}"
end

# 关闭Socket连接
socket.close
