Python 擴展：aiozmq

aiozmq 是 Asyncio (pep 3156) 與 ZeroMQ 的集成。

import asyncio
import aiozmq.rpc


class ServerHandler(aiozmq.rpc.AttrHandler):

    @aiozmq.rpc.method
    def remote_func(self, a:int, b:int) -> int:
        return a + b


@asyncio.coroutine
def go():
    server = yield from aiozmq.rpc.serve_rpc(
        ServerHandler(), bind='tcp://127.0.0.1:5555')
    client = yield from aiozmq.rpc.connect_rpc(
        connect='tcp://127.0.0.1:5555')

    ret = yield from client.call.remote_func(1, 2)
    assert 3 == ret

    server.close()
    client.close()

asyncio.get_event_loop().run_until_complete(go())

Low-level request-reply example:

import asyncio
import aiozmq
import zmq

@asyncio.coroutine
def go():
    router = yield from aiozmq.create_zmq_stream(
        zmq.ROUTER,
        bind='tcp://127.0.0.1:*')

    addr = list(router.transport.bindings())[0]
    dealer = yield from aiozmq.create_zmq_stream(
        zmq.DEALER,
        connect=addr)

    for i in range(10):
        msg = (b'data', b'ask', str(i).encode('utf-8'))
        dealer.write(msg)
        data = yield from router.read()
        router.write(data)
        answer = yield from dealer.read()
        print(answer)
    dealer.close()
    router.close()

asyncio.get_event_loop().run_until_complete(go())
