Python基础-UDP编程

服务器

import socket

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

#绑定端口
s.bind(('127.0.0.1', 10000))

print('udp bind ok')

while True:
#等待收数据
data ,addr = s.recvfrom(1024)
print('recv data %s from %s' % (data,addr))
s.sendto(b'hehe %s' % data, addr)

客户端

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
for data in [b'Tom', b'Rose', b'Jack']:
# 发送数据:
s.sendto(data, ('127.0.0.1', 10000))
# 接收数据:
print(s.recv(1024).decode('utf-8'))
s.close()

总结

#服务器打印结果
udp bind ok
recv data b'Tom' from ('127.0.0.1', 60627)
recv data b'Rose' from ('127.0.0.1', 60627)
recv data b'Jack' from ('127.0.0.1', 60627)

#客户端打印结果
hehe Tom
hehe Rose
hehe Jack
