UDP プロトコルに基づいた LAN ブロードキャスト機能を実装する Python+Socket の詳細な例

# udp_gb_server.py
'''服务端（UDP协议局域网广播）'''
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
PORT = 1060
network = &#39;<broadcast>&#39;
s.sendto(&#39;Client broadcast message!&#39;.encode(&#39;utf-8&#39;), (network, PORT))

# udp_gb_client.py
'''客户端（UDP协议局域网广播）'''
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
PORT = 1060
s.bind(('', PORT))
print('Listening for broadcast at ', s.getsockname())
while True:
  data, address = s.recvfrom(65535)
  print('Server received from {}:{}'.format(address, data.decode('utf-8')))
