python+soket实现UDP协议的局域网广播程序

 

 1 # udp_gb_server.py
 2 '''服务端(UDP协议局域网广播)'''
 3 
 4 import socket
 5 
 6 s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
 7 s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
 8 
 9 PORT = 1060
10 
11 network = '<broadcast>'
12 s.sendto('Client broadcast message!'.encode('utf-8'), (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')))
