根因分析

aiohttp 的 ClientSession 未正确关闭，导致底层传输连接保持打开状态。

English

An aiohttp ClientSession is not properly closed, leaving underlying transport connections open.

generic

解决方案

  1. 95% 成功率 Use async with for session lifecycle 
    async with aiohttp.ClientSession() as session:
    async with session.get(url) as resp:
        data = await resp.text()
  2. 90% 成功率 Explicitly await session.close() in a finally block 
    session = aiohttp.ClientSession()
try:
    # use session
finally:
    await session.close()

无效尝试

常见但无效的做法:

  1. Calling session.close() without awaiting it 80% 失败

    session.close() is a coroutine; not awaiting it leaves the session unclosed.

  2. Relying on garbage collection to close the session 60% 失败

    GC may not run immediately, and the warning appears due to delayed cleanup.
