利用多进程或多线程自己实现TCP服务端的并发

from socket import *
from threading import Thread

server = socket(AF_INET,SOCK_STREAM)
server.bind(('127.0.0.1',8080))
server.listen(5)

def func(conn):
    while True:
        try:
            date = conn.recv(1024)
            if len(date) == 0:break
            print(date.decode('utf-8'))
            conn.send(date.upper())
        except Exception as e:
            print(e)
            break
    conn.close()

if __name__ == '__main__':
    while True:
        conn,client_addrs = server.accept()
        t = Thread(target=func,args=(conn,))
        t.start()
