套接字 - 基于TCP协议创建时间服务器

from socket import *
from time import *

server = socket(AF_INET, SOCK_STREAM)
server.bind(('localhost', 6789))
server.listen()
print('服务器已经启动正在监听客户端连接.')
while True:
    client, addr = server.accept()
    print('客户端%s:%d连接成功.' % (addr[0], addr[1]))
    currtime = localtime(time())
    timestr = strftime('%Y-%m-%d %H:%M:%S', currtime)
    client.send(timestr.encode('utf-8'))
    client.close()
server.close()

from socket import *

client = socket(AF_INET, SOCK_STREAM)
client.connect(('localhost', 6789))
while True:
    data = client.recv(1024)
    if not data:
        break
    print(data.decode('utf-8'))
client.close()

使用socketserver模块创建时间服务器

from socketserver import TCPServer, StreamRequestHandler
from time import *


class EchoRequestHandler(StreamRequestHandler):

    def handle(self):
        currtime = localtime(time())
        timestr = strftime('%Y-%m-%d %H:%M:%S', currtime)
        self.wfile.write(timestr.encode('utf-8'))


server = TCPServer(('localhost', 6789), EchoRequestHandler)
server.serve_forever()
