170925_2 Python socket 创建UDP的服务器端和客户端

【python版本】3.6

UDP服务器端：

 1 from socket import *
 2 from time import ctime
 3 
 4 host = ''
 5 port = 21567
 6 buf_size = 1024
 7 addr = (host, port)
 8 
 9 udpSerSock = socket(AF_INET, SOCK_DGRAM)
10 udpSerSock.bind(addr)
11 
12 while True:
13     print("waiting for message...")
14     data, ADDR = udpSerSock.recvfrom(buf_size)
15     response = '[%s] %s' % (ctime(), data.decode('utf-8'))
16     udpSerSock.sendto(response.encode('utf-8'), ADDR)
17     print("...received from and returned to:", ADDR)
18 
19 udpSerSock.close()

UDP客户端：

 1 from socket import *
 2 
 3 
 4 host = 'localhost'
 5 port = 21567
 6 buf_size = 1024
 7 addr = (host, port)
 8 
 9 
10 udpCliSock = socket(AF_INET, SOCK_DGRAM)
11 
12 while True:
13     data = input('>')
14     if not data:
15         break
16     udpCliSock.sendto(data.encode('utf-8'), addr)
17     data, addr = udpCliSock.recvfrom(buf_size)
18     if not data:
19         break
20     print(data.decode('utf-8'))
21 
22 udpCliSock.close()
