python udp socket示例

服务端

#!/usr/bin/python3

import socket

print("server")
host = ''
port = 9999
address = (host,port)

s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

s.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,True)

s.bind(address)

recvdata,c = s.recvfrom(1024)
print(recvdata)
s.close()

客户端

#!/usr/bin/python3

import socket

print("client")
# host = socket.gethostname()
host = '127.0.0.1'
port = 9999
address = (host,port)

s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

msg = b'client->server'

s.sendto(msg,address)

s.close()
