伺服器端：gevent_server.py

import sysimport socketimport timeimport geventfrom gevent import socket, monkeymonkey.patch_all()def server(port):    s = socket.socket()    s.bind((‘0.0.0.0‘, port))    s.listen(500)    while True:        cli, addr = s.accept()        gevent.spawn(handle_request, cli)#啟動一個協程def handle_request(conn):    try:        while True:            data = conn.recv(1024)            print("recv:", data)            conn.send(data)            if not data:                conn.shutdown(socket.SHUT_WR)    except Exception as  ex:        print(ex)    finally:        conn.close()if __name__ == ‘__main__‘:        server(8001)

 用戶端:socket_client.py

import socketHOST = ‘localhost‘  # The remote hostPORT = 8001  # The same port as used by the servers = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.connect((HOST, PORT))while True:    msg = bytes(input(">>:"), encoding="utf8")    s.sendall(msg)    data = s.recv(1024)    #    print(‘Received‘, data)s.close()
