根因分析

在 Python 3.11+ 中，asyncio.timeout() 返回异步上下文管理器，而不是可等待对象。为 asyncio.wait_for 或旧模式编写的代码错误地 await 了它。

English

In Python 3.11+, asyncio.timeout() returns an async context manager, not an awaitable. Code written for asyncio.wait_for or older patterns mistakenly awaits it.

解决方案

  1. 95% 成功率 
    async with asyncio.timeout(5):
    data = await fetch()
  2. 88% 成功率 
    try:
    async with asyncio.timeout(5):
        return await fetch()
except AttributeError:
    return await asyncio.wait_for(fetch(), timeout=5)
  3. 90% 成功率 
    import time
loop = asyncio.get_running_loop()
deadline = loop.time() + 5
async with asyncio.timeout_at(deadline):
    await fetch()

无效尝试

常见但无效的做法:

  1. 90% 失败

    Timeout is not callable; raises TypeError: 'Timeout' object is not callable.

  2. 85% 失败

    wait_for expects an awaitable; Timeout is a context manager, not awaitable.
