根因分析

客户端断开或响应已完成后，aiohttp 服务器仍尝试向 StreamResponse 写入数据。

English

aiohttp server tried to write to a StreamResponse after the client disconnected or the response was already finalized.

generic

解决方案

  1. 90% 成功率 
    if request.transport is None or request.transport.is_closing():
    return
await resp.write(chunk)
  2. 88% 成功率 
    resp = web.StreamResponse()
await resp.prepare(request)
try:
    async for chunk in source:
        await resp.write(chunk)
except (ConnectionResetError, RuntimeError):
    pass
finally:
    await resp.write_eof()

无效尝试

常见但无效的做法:

  1. 70% 失败

    Silently drops data and may hide application logic bugs.

  2. 85% 失败

    The transport is already closing; timeout is unrelated.
