Python:url内容的简单异步下载？

import asyncio
import aiohttp

async def download_url(url):
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            return await response.read()

async def main():
    url = "https://example.com"
    content = await download_url(url)
    print(content)

if __name__ == "__main__":
    asyncio.run(main())
