trust_env= True在创建客户端时添加了该链接，现在一切正常。这是新代码：
import asyncioimport aiohttpasync def main(): loop = asyncio.get_event_loop() url = "https://stackoverflow.com/" async with aiohttp.ClientSession(loop=loop, trust_env=True) as session: async with session.get(url, timeout=30) as resp: print(resp.status)asyncio.run(main())
