基于TCP协议套接字，服务端实现接收客户端的连接并发

服务端
import socket
from multiprocessing import Process

server=socket.socket()
server.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
server.bind(('127.0.0.1',8080))
server.listen(5)

def talk(conn,client_addr):
    while True:
        try:
            msg=conn.recv(1024)
            if not msg:break
            conn.send(msg.upper())
        except Exception:
            break

if __name__ == '__main__': # windows下start进程一定要写到这下面
    while True:
        conn,client_addr=server.accept()
        p=Process(target=talk,args=(conn,client_addr))
        p.start()
        
        
客户端
import socket

client=socket.socket()
client.connect(('127.0.0.1',8080))

while True:
    msg=input('>>: ').strip()
    if not msg:continue

    client.send(msg.encode('utf-8'))
    msg=client.recv(1024)
    print(msg.decode('utf-8'))
