tcp实现并发效果

服务端

from multiprocessing import Process
from threading import Thread
import socket
import time
​
# TCP 服务端实现并发的效果
​
server = socket.socket()
server.bind(('127.0.0.1', 8083))
server.listen(5)
​
​
# 通信循环
def talk(conn):
    while 1:
        try:
            data = conn.recv(1024)
            if len(data) == 0: break
            print(data.decode('utf-8'))
            conn.send(data.upper())
        except Exception as e:
            print(e)
            break
    conn.close()
​
​
while 1:
    conn, addr = server.accept()
    # t = Process(target=talk,args=(conn,))
    t = Thread(target=talk, args=(conn,))
    t.start()

客户端

import socket
import time
​
# 客户端
# 不输入默认是TCP协议
client = socket.socket()
client.connect(('127.0.0.1', 8083))
​
while 1:
    client.send(b'hello world')
    data = client.recv(1024)
    print(data.decode('utf-8'))
