并发编程-基于多进程实现并发套接字通信

服务端：

from socket import *
from multiprocessing import Process

def talk(conn):
    while True:
        try:
            data = conn.recv(1024)
            if not data: break
            conn.send(data.upper())
        except ConnectionRefusedError:
            break
    conn.close()

def server(ip,port):
    server=socket(AF_INET,SOCK_STREAM)
    server.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
    server.bind((ip,port))
    server.listen(5)

    while True:
        conn, client_addr = server.accept()
        p = Process(target=talk,args=(conn,))
        p.start()

    server.close()

if __name__ == '__main__':
    server('127.0.0.1',8080)

客户端：

from socket import *

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

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

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