170925_1 Python socket 创建TCP的服务器端和客户端

【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：

 from socket import *

 from time import ctime

 host = ''

 port = 21563

 buf_size = 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(buf_size)

         print(data)

         print(bytes(ctime(), 'utf-8'))

         if not data:

             break

         response = '[%s] %s' % (ctime(), data.decode('utf-8'))

         tcpCliSock.send(response.encode('utf-8'))

     tcpCliSock.close()

 tcpSerSock.close()

创建TCP客户端：

 from socket import *

 host = 'localhost'

 port = 21563

 buf_size = 1024

 addr = (host, port)

 tcpCliSock = socket(AF_INET, SOCK_STREAM)

 tcpCliSock.connect(addr)

 while True:

     data = input('>')

     if not data:

         break

     tcpCliSock.send(data.encode('utf-8'))

     data = tcpCliSock.recv(buf_size)

     if not data:

         break

     print(data.decode())

 tcpCliSock.close()
