简单的UDP测试

# UDP：server
import socket

ss = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
ss.bind(('127.0.0.1', 8080))

while True:
    data, client_addr = ss.recvfrom(2)
    print('客户端信息：', data.decode('utf-8'))
    print('客户端地址：', client_addr)

# UDP client
import socket

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

while True:
    data = input('>>:').strip()
    if data == 'exit()':
        break
    flag = ss.sendto(data.encode('utf-8'), ('127.0.0.1', 8080))
    print('标志位：', flag)
ss.close()
