Izisekelo zokusebenza ne-zmq ku-python, ukudala ukhiye olula/isitolo senani

Isingeniso

Ake sibheke isibonelo sokhiye olula/isitoreji senani, njenge-memcache. Yakhelwe kalula - idatha igcinwa enkumbulweni, esakhiweni se-hashmap. Afinyelelwa ngesokhethi ye-tcp. E-Python, i-hashmap iyisimiso esivamile. Ukuze sifinyelele sizosebenzisa i-zeromq.

Yenza ngokwezifiso

Ukufaka le phakheji ku-debian/ubuntu, vele ufake ikhonsoli
sudo apt-get install libzmq-dev
sudo pip install zmq

Ikhodi

Masibhale ikilasi ukuze sisebenze neseva yethu:
Uhlobo lwesokhethi le-zmq elisetshenzisiwe REQ(ISICELO, isicelo), sithumela isicelo bese silinda impendulo.
Ukugcina nokudlulisa noma yiluphi uhlobo lwedatha kunethiwekhi, sisebenzisa imojuli ye-pickle evamile. "Iphrothokholi" yomsebenzi iyinani lamanani amathathu: (umyalo, ukhiye, idatha)

import zmq
import pickle

class SuperCacher:
    def __init__(self):
        context = zmq.Context()
        self.socket = context.socket(zmq.REQ)
        self.socket.connect('tcp://127.0.0.1:43000')

    def get(self, key):
        self.socket.send(pickle.dumps(('get', key, None)))
        return pickle.loads(self.socket.recv())

    def set(self, key, data):
        self.socket.send(pickle.dumps(('set', key, data)))
        return self.socket.recv() == b'ok'

Sebenzisa

inqolobane = SuperCacher()
cache.set('ukhiye', 'value')
i-cache.get('ukhiye')

Njengomsebenzi wasekhaya, thuthukisa ukusetshenziswa ngokungeza ikhono lokucacisa ikheli/imbobo lapho udala isibonelo sekilasi.

Manje ake sibhale iseva ngokwayo.
Kulokhu kusetshenziswa isokhethi REP(PHENDULA, impendulo) - silinde isicelo, sithumela impendulo. Sihlaziya isicelo futhi siphendule ngokuthi 'kulungile' uma sibhala, noma ngedatha / Akukho lapho kufundwa.

import pickle
import json
import zmq

def run_daemon():
    memory = {}

    context = zmq.Context()
    socket = context.socket(zmq.REP)
    socket.bind('tcp://127.0.0.1:43000')

    while True:
        try:
            command, key, data = pickle.loads(socket.recv())
            if command == 'set':
                memory[key] = data
                socket.send(b'ok')
            elif command == 'get':
                result = memory.get(key, None)
                socket.send(pickle.dumps(result))
        except Exception as e:
            print(e)

if __name__ == '__main__':
    run_daemon()

Ukuhlola konke ndawonye, ​​siqala iseva ngomyalo
python daemon.py

Kuthebhu elandelayo, vula i-python kumodi yokusebenzisana.

>>> from lib import SuperCacher
>>> cache=SuperCacher()
>>> cache.set('key', 'value')
True
>>> cache.get('key')
'value'

O isimangaliso, siyasebenza! Manje usungakwazi ukubhala ngokuphepha ku-resume yakho "ukuthuthukiswa kwesitoreji senani elingukhiye usebenzisa iphrothokholi ye-zmq"
