根因分析

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。

English

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

解决方案

  1. 92% 成功率 
    Read the body once and cache:

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

无效尝试

常见但无效的做法:

  1. 90% 失败

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

  2. 85% 失败

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

  3. 90% 失败

    Server-side framing, not client-controlled.
