实例详解Python+Socket实现基于UDP协议的局域网广播功能

本文实例讲述了Python+Socket实现基于UDP协议的局域网广播功能。分享给大家供大家参考，具体如下：

服务器端：

# 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 = '<broadcast>'
s.sendto('Client broadcast message!'.encode('utf-8'), (network, PORT))

客户端：

# 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')))

运行效果：
