Root Cause

The server closed the connection mid-body, or the response body was read twice, or streaming was interrupted.

generic

中文

服务器在响应体中间关闭了连接,或响应体被读取两次,或流式传输被中断。

Workarounds

  1. 92% success
    Read the body once and cache:
    
    async with session.get(url) as resp:
        body = await resp.read()
        data = json.loads(body)
  2. 88% success
    Retry the request on ClientPayloadError with backoff.
  3. 85% success
    Use resp.content.iter_chunked() for large payloads to detect partial reads early.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The body is consumed once; second call raises the same error.

  2. 85% fail

    The connection is already closed; timeout doesn't matter.

  3. 90% fail

    Server-side framing, not client-controlled.
