Today's job
1. Arrange the classroom content
2. Write a realization of concurrent connections receiving client is based on TCP socket server.
* Import socket from
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 end
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'))
