Python 调用multiprocessing模块下面的Process类方法（实现服务器、客户端并发）-TCP协议

方法一：
服务端：
from multiprocessing import Process
import socket

def task(conn):    #通信循环
    while True:
        cmd = conn.recv(1024)
        if len(cmd) == 0:break
        conn.send(cmd.upper())
        print(cmd.decode('utf-8'))

if __name__ == '__main__':
    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server.bind(('127.0.0.1', 8080))
    server.listen(5)
    # 1.让客户端连进来
    # 2.建立连接需要一个单独的
    conn,client_addr=server.accept()
    p=Process(target=task,args=(conn,))   #连接循环
    p.start()

--------------------------------------------------------------------------------------------------------
客户端：

import socket
client=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client.connect(('127.0.0.1',8080))

while True:
    msg=input('输入你要的信息：')
    client.send(msg.encode('utf-8'))
    if len(msg) == 0:continue

    data=client.recv(1024)
    print(data.decode('utf-8'))
client.close()
