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=
 BUFSIZ=
 ADDR=(HOST,PORT)
 tcpSerSock=socket(AF_INET,SOCK_STREAM)
 tcpSerSock.bind(ADDR)
 tcpSerSock.listen()
 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=
 BUFSIZ=
 ADDR=(HOST,PORT)
 tcpSerSock=socket(AF_INET,SOCK_STREAM)
 tcpSerSock.bind(ADDR)
 tcpSerSock.listen()
 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=
 BUFSIZ=
 ADDR=(HOST,PORT)
 tcpSerSock=socket(AF_INET,SOCK_STREAM)
 tcpSerSock.bind(ADDR)
 tcpSerSock.listen()
 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
