根因分析

aiohttp.ClientSession 已被关闭（通过 async with 或 session.close()），但仍有协程尝试用它发起请求。

English

An aiohttp.ClientSession was closed (via async with or session.close()) but a coroutine still attempted to use it to make a request.

解决方案

  1. 95% 成功率 
    session = aiohttp.ClientSession()
try:
    await fetch_all(session)
finally:
    await session.close()
  2. 93% 成功率 
    async with aiohttp.ClientSession() as session:
    async with session.get(url) as resp:
        data = await resp.text()

无效尝试

常见但无效的做法:

  1. 70% 失败

    Reassigning does not resurrect the closed object; any references held elsewhere still point to the closed session.

  2. 85% 失败

    The connector is also closed with the session; manual connect raises the same error.
