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):    #通讯循环
    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.创建链接须要一个单独的
    conn,client_addr=server.accept()
    p=Process(target=task,args=(conn,))   #链接循环
    p.start()

客户端：

import socketclient=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()
