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:

?
1
2
3
4
5
6
7
8
# 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:

?
1
2
3
4
5
6
7
8
9
10
11
# 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:
