Posted on:

Last modified:

aiohttp 是 Python 异步编程生态中出现比较早的一个 http 请求库,依托于 asyncio, 性能非常吓人。 下面列举几个常见的用法:

import aiohttp
import asyncio

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    urls = [
    tasks = []
    async with aiohttp.ClientSession() as session:
        for url in urls:
            tasks.append(fetch(session, url))
        htmls = await asyncio.gather(*tasks)
        for html in htmls:

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
