利用队列Queue实现一个多并发“线程池”效果的Socket程序

　　本例通过利用类Queue建立了一个存放着Thread对象的“容器对象”，当Client端申请与Server端通信时，在Server端的“链接循环”中每次拿出一个Thread对象去创建“线程链接”，从而实现了多个客户端同时与服务器端通信的效果，代码如下：

# -*- coding: utf-8  -*-
# -*- Author: WangHW -*-
import socket
from threading import Thread
import mythread

def Communication(conn):
    # 通信循环
    while 1:
        try:
            data = conn.recv(1024)
            if not data:
                break
            print('Client Data:', data.decode('utf-8'))
            conn.send(data.upper())
        except ConnectionResetError:
            break

def Server(ip,post):
    whw_server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    whw_server.bind((ip,post))
    whw_server.listen(5)
    # 链接循环
    while 1:
        conn, addr = whw_server.accept()
        t = pool.get_thread()
        #使用线程对象创建线程
        obj = t(target=Communication, args=(conn,))
        obj.start()  # 启动线程

if __name__ == '__main__':
    pool = mythread.MyThread(3)
    #主线程干Server的工作
    Server('127.0.0.1',9001)

Server

# -*- coding: utf-8  -*-
# -*- Author: WangHW -*-
import socket

whw_client = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
whw_client.connect(('127.0.0.1',9001))

while 1:
    msg = input('>>>:').strip()
    if not msg:
        continue
    whw_client.send(msg.encode('utf-8'))
    data = whw_client.recv(1024)
    print('Server Data:',data.decode('utf-8'))

Client

　　新建一个mythread.py文件，专门进行队列的操作：

# -*- coding: utf-8  -*-
# -*- Author: WangHW -*-
from threading import Thread
from queue import Queue
class MyThread:
    def __init__(self,maxthread):
        self.maxthread = maxthread
        #初始化一个Queue对象
        self.q = self.queue =Queue(maxthread)
        #在队列中存放maxthread个对象，起到线程池的作用
        for i in range(maxthread):
            self.q.put(Thread)

    def put_thread(self):
        '''put'''
        self.q.put(Thread)

    def get_thread(self):
        '''get'''
        return self.q.get()

mythread

　　如果设置最大的并发数为3，所以只能同时有3个客户端与服务器端通信：
