1.3用socketserver创建服务器

socket服务器代码

# -*- coding: utf-8 -*-
import socketserver,time
 
myHost = ''
myPort = 50007
def now():                                                    #返回一个时间
    return time.ctime(time.time()) 
 
class MyClientHandler(socketserver.BaseRequestHandler):
    def handle(self):                                          #处理每一个连接的用户
        print(self.client_address,now())                       #打印该用户地址
        time.sleep(5)                                          #模拟一个运行
        while True:                                            #self.reqeust指的是用户
            data = self.request.recv(1024)                     # 从客户端接受信息
            if not data: break
            reply = 'Ech0=>%s at %s'%(data,now())
            self.request.send(reply.encode())                  #发送信息给客户端
        self.request.close()
 
#创建线程，让服务器一直运行下去
myaddr = (myHost,myPort)
server = socketserver.ThreadingTCPServer(myaddr,MyClientHandler)
server.serve_forever()

socket客户端测试代码

# -*- coding: utf-8 -*-
from socket import *
 
serverHost = 'localhost'
serverPort = 50007
 
while True:
    messages = [input('输入').encode()]             #输入信息，并设置编码， 可设置b''或者str.encode()
 
    socketobj = socket(AF_INET, SOCK_STREAM)        # 创建TCP对象
    socketobj.connect((serverHost, serverPort))     # 连接端口
 
    for line in messages:
        socketobj.send(line)
        data = socketobj.recv(1024)                 # 从服务器接受信息
        print('Client received:', data.decode())    #打印信息，解码打印,str.decode()
 
    socketobj.close()
