from socket import *
HOST = 'localhost'

BUFSIZ = 1024
ADDR = (HOST,PORT)
tcpCliSock = socket(AF_INET,SOCK_STREAM)
tcpCliSock.connect(ADDR)
while True:
data = input('>')
if not data:
break
tcpCliSock.send(data)
data = tcpCliSock.recv(BUFSIZ)
if not data:
break
print(data.decode('utf-8'))
tcpCliSock.close()
改程序运行后出现:TypeError: a bytes-like object is required, not 'str' 告警,什么原因?
