# 添加超时和重试机制
def call_stream_api_with_retry(url, max_retries=3):
    for attempt in range(max_retries):
        try:
            with httpx.stream("POST", url, timeout=httpx.Timeout(60.0, read=30.0)) as response:

                        process_chunk(chunk)
                    break  # 成功完成则退出重试循环
        except httpx.ReadError as e:
            if attempt == max_retries - 1:
                raise RuntimeError(f"流式请求在尝试{max_retries}次后仍失败: {e}")

4. 🛡️ 预防措施

• 客户端层面：设置合理的读超时和连接超时，添加断点续传能力，避免长时间阻塞等待


• 服务端层面：检查服务端负载和网络稳定性，确认流式响应能完整发送终止帧，监控日志排查异常断开原因
