socket模块tcp通过多进程并发连接多个客户端

#server端
import socket
from multiprocessing import Process


def talk(conn):
    while True:
        msg = conn.recv(1024).decode('utf-8')
        ret = msg.upper().encode('utf-8')
        conn.send(ret)
    conn.close()

if __name__ =='__main__':
    sk = socket.socket()
    sk.bind(('127.0.0.1',9001))
    sk.listen()
    while True:
        conn,_ = sk.accept()
        Process(target=talk,args=(conn,)).start()
    
    sk.close()

#clent端

import time
import socket
sk = socket.socket()
sk.connect(('127.0.0.1',9001))
while True:
    sk.send(b'hello')
    msg = sk.recv(1024).decode('utf-8')
    print(msg)
    time.sleep(0.5)

sk.close()

 

通过开启子进程，异步不阻塞。

类下通过socketserver模块进行tcp多客户端通信：

#server端
import time
import socketserver
class Myserver(socketserver.BaseRequestHandler):
    def handle(self):
        conn = self.request
        while True:
            try:
                content = conn.recv(1024).decode('utf-8')
                conn.send(content.upper().encode('utf-8'))
                time.sleep(0.5)
            except ConnectionError:
                break
server = socketserver.ThreadingTCPServer(('127.0.0.1',9001),Myserver)
server.serve_forever()

client端同上.
