PythonTCP服務端客戶端

1.tcp服務端server

 1 from socket import *
 2 from time import ctime
 3 
 4 HOST = ``
 5 PORT = 9999
 6 BUFSIZ = 1024
 7 ADDR = (HOST, PORT)
 8 
 9 tcpSerSock = socket(AF_INET, SOCK_STREAM)   #建立套接字
10 tcpSerSock.bind(ADDR)   #繫結IP和埠
11 tcpSerSock.listen(5)    #監聽埠，最多5人排隊
12 
13 while True:
14     print(`waiting for connection...`)
15     tcpCliSock, addr = tcpSerSock.accept()    #建立連線
16     print(`...connected from:`, addr)
17 
18     while True:
19         data = tcpCliSock.recv(BUFSIZ)
20         if not data:
21             break
22         content = `[%s] %s` % (bytes(ctime(), "utf-8"), data)
23         print(data)
24         print(type(content))
25         tcpCliSock.send(content.encode("utf-8"))
26 
27     tcpCliSock.close()
28 
29 tcpSerSock.close()

 

 

2.tcp客戶端client

 1 from socket import *
 2 
 3 HOST = `127.0.0.1`  # or `localhost`
 4 PORT = 9999
 5 BUFSIZ = 1024
 6 ADDR = (HOST, PORT)
 7 
 8 tcpCliSock = socket(AF_INET, SOCK_STREAM)
 9 tcpCliSock.connect(ADDR)
10 
11 while True:
12     data = input(`> `)
13     if not data:
14         break
15 
16     tcpCliSock.send(data.encode("utf-8"))
17     data = tcpCliSock.recv(BUFSIZ)
18     if not data:
19         break
20     print(data.decode("utf-8"))
21 
22 tcpCliSock.close()
