UDP广播案例,一端发送,多端接受:
发送端:
# UDP广播案例
from socket import *
from time import sleep
# 设定目标地址
dest=('176.215.122.255',6666)
s=socket(AF_INET,SOCK_DGRAM)
s.setsockopt(SOL_SOCKET,SO_BROADCAST,1)
data='本人到此一游'
while True:
sleep(2)
s.sendto(data.encode(),dest)
s.close()
接收端:
# udp广播案例
from socket import *
s=socket(AF_INET,SOCK_DGRAM)
# 设置套接字
s.setsockopt(SOL_SOCKET,SO_BROADCAST,1)
# 选择一个接收地址
s.bind(('0.0.0.0',9821))
while True:
try:
msg,addr=s.recvfrom(1024)
print('from %s bg %s'% (addr,msg.decode()))
except KeyboardInterrupt:
break
except Exception as e:
print(e)
s.close()
