根因分析

在任务完成之前调用了 task.result() 或 task.exception()，二者都要求任务处于 DONE 状态。

English

task.result() or task.exception() was called before the task completed; both require the task to be in the DONE state.

generic

解决方案

  1. 97% 成功率 
    task = asyncio.create_task(work())
result = await task
  2. 92% 成功率 
    done, pending = await asyncio.wait({task}, timeout=10)
if task in done:
    print(task.result())

无效尝试

常见但无效的做法:

  1. 80% 失败

    Arbitrary sleeps are racy; under load the task may still be pending.

  2. 70% 失败

    Busy-looping until done wastes CPU and does not guarantee completion.
