今日作业

1.整理课堂内容
2.写一个基于TCP协议套接字，服务端实现接收客户端的连接并发。
from socket import *
from multiprocessing import Process

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

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