loop = asyncio.get_event_loop()
loop.run_until_complete(main(url))回溯

- windows 10
- python 3.9.7
- aiohttp 3.7.4.post0
如果我获得带有ssl=False参数的请求，一切都会正常工作。但我不认为这是解决问题的正确办法。

因此，您需要为您的python版本安装证书。在mac上，您可以在终端窗口中运行下面的内容，它可以解决您的问题。

我想我解决了这个问题。您可以安装证书并使用其证书。
import aiohttp
import asyncio
import ssl
import certifi
async def main(url):
ssl_context = ssl.create_default_context(cafile=certifi.where())
conn = aiohttp.TCPConnector(ssl=ssl_context)
async with aiohttp.ClientSession(connector=conn) as session:
async with session.get(url) as response:
print("Status:", response.status)
url = "https://shikimori.one/"
loop = asyncio.get_event_loop()
loop.run_until_complete(main(url))如果没有帮助，可以尝试按描述的here手动添加证书
