1.2socket服务器使用多线程

socket服务器代码如下

# -*- coding: utf-8 -*-
from socket import *
import time
import threading,_thread as thread

myHost = ''                                                                #''说明所有IP都可以连接
myPort = 50007                                                             #设置一个端口

socketobj = socket(AF_INET,SOCK_STREAM)                                    #创建TCP对象
socketobj.bind((myHost,myPort))                                            #绑定端口
socketobj.listen(5)                                                        #允许5个请求连接

def now():
    return time.ctime(time.time())

def handleClient(connection):
    #time.sleep(5)
    while True:
        data = connection.recv(1024)                                       #每次读取最多1024字节
        if not data: break
        reply = 'Echo=> %s at %s' % (data,now())                           #发送数据给客户端
        connection.send(reply.encode())
    connection.close()

def dispatcher():
    while True:
        connection,address = socketobj.accept()                             #接受数据并打印
        print('Server connected by,',address,end='')
        print('at',now())
        #thread.start_new_thread(handleClient,(connection,))                #使用多线程
        thread = threading.Thread(target=handleClient,args=(connection,))   #使用多线程
        thread.start()                                                      #开始线程

dispatcher()

socket客户端代码如下

# -*- 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()
