pytho核心编程2-1中代码运行问题

书籍是《python核心编程》第三版，学习环境py3.6

2-1 时间戳服务器

附源代码：

from socket import  *
from time import ctime
HOST=''
PORT=8888
BUFSIZ=1024
ADDR=(HOST,PORT)
tcpSerSock=socket(AF_INET,SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)
while True:
    print("waiting for connection...")
    tcpCliSock,addr=tcpSerSock.accept()
    print('connected from:',addr)
    while True:
        data=tcpCliSock.recv(BUFSIZ).decode()
        if not data:
            break
        tcpCliSock.send(("[%s]%s"%(ctime(),data)))
        tcpCliSock.close()
    tcpSerSock.close()

运行后

Traceback (most recent call last):
File "F:/learn_test/时间戳服务器.py", line 18, in <module>
tcpCliSock.send(("[%s]%s" % (ctime(), data)))
TypeError: a bytes-like object is required, not 'str'

提示需要一个bytes类型的对象，而不是str

。。。。照着书敲都会有错

这还能难住老夫？

from socket import  *
from time import ctime
HOST=''
PORT=8888
BUFSIZ=1024
ADDR=(HOST,PORT)
tcpSerSock=socket(AF_INET,SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)
while True:
    print("waiting for connection...")
    tcpCliSock,addr=tcpSerSock.accept()
    print('connected from:',addr)
    while True:
        data=tcpCliSock.recv(BUFSIZ).decode()
        if not data:
            break
        tcpCliSock.send(("[%s]%s"%(ctime(),data)).encode())
        tcpCliSock.close()
    tcpSerSock.close()

然后继续运行

Traceback (most recent call last):
File "F:/learn_test/时间戳服务器.py", line 15, in <module>
data=tcpCliSock.recv(BUFSIZ).decode()
OSError: [WinError 10038] 在一个非套接字上尝试了一个操作。

修正后

from socket import  *
from time import ctime
HOST=''
PORT=8888
BUFSIZ=1024
ADDR=(HOST,PORT)
tcpSerSock=socket(AF_INET,SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)
while True:
    print("waiting for connection...")
    tcpCliSock,addr=tcpSerSock.accept()
    print('connected from:',addr)
    while True:
        data=tcpCliSock.recv(BUFSIZ).decode()
        if not data:
            break
        # tcpCliSock.send(("[%s]%s" % (ctime(), data)))
        tcpCliSock.send(("[%s]%s"%(ctime(),data)).encode())
    tcpCliSock.close()
    tcpSerSock.close()

区别就是描红的那一行

本次表演到此结束
