【Python版本】3.6
【遇到的问题】
客户端和服务器端都遇到:TypeError: a bytes-like object is required, not 'str'
【解决方案】
参考:https://stackoverflow.com/questions/13274553/python-3-3-socket-typeerror
创建TCP服务器端:
1 from socket import * 2 from time import ctime 3 4 host = '' 5 port = 21563 6 buf_size = 1024 7 addr = (host, port) 8 9 10 tcpSerSock = socket(AF_INET, SOCK_STREAM) 11 tcpSerSock.bind(addr) 12 tcpSerSock.listen(5) 13 14 while True: 15 print("waiting for connection....") 16 tcpCliSock, ADDR = tcpSerSock.accept() 17 print("...connected from:", ADDR) 18 19 while True: 20 data = tcpCliSock.recv(buf_size) 21 print(data) 22 print(bytes(ctime(), 'utf-8')) 23 if not data: 24 break 25 response = '[%s] %s' % (ctime(), data.decode('utf-8')) 26 tcpCliSock.send(response.encode('utf-8')) 27 tcpCliSock.close() 28 29 tcpSerSock.close()
创建TCP客户端:
1 from socket import * 2 3 4 host = 'localhost' 5 port = 21563 6 buf_size = 1024 7 addr = (host, port) 8 9 tcpCliSock = socket(AF_INET, SOCK_STREAM) 10 tcpCliSock.connect(addr) 11 12 while True: 13 data = input('>') 14 15 if not data: 16 break 17 tcpCliSock.send(data.encode('utf-8')) 18 data = tcpCliSock.recv(buf_size) 19 if not data: 20 break 21 print(data.decode()) 22 23 tcpCliSock.close()
