小编scp*_*pio的帖子

我想非常快地连接到很多不同网站的列表.我使用asyncio以异步方式执行此操作,现在想要添加超时,以便在需要花费太长时间来响应时忽略连接.

我该如何实现？

import ssl
import asyncio
from contextlib import suppress
from concurrent.futures import ThreadPoolExecutor
import time


@asyncio.coroutine
def run():
    while True:
        host = yield from q.get()
        if not host:
            break

        with suppress(ssl.CertificateError):
            reader, writer = yield from asyncio.open_connection(host[1], 443, ssl=True) #timout option?
            reader.close()
            writer.close()


@asyncio.coroutine
def load_q():
    # only 3 entries for debugging reasons
    for host in [[1, 'python.org'], [2, 'qq.com'], [3, 'google.com']]:
        yield from q.put(host)
    for _ in range(NUM):
        q.put(None)


if __name__ == "__main__":
    NUM = 1000
    q = …
