AI 解决方案
🔍 报错分析
1. 🌐 错误翻译
原文：WARNING - Query refinement failed: Request timed out.
译文：警告 - 查询优化失败：请求超时。
2. 🎯 原因分析
根本原因：查询优化过程中请求超时，导致整个查询优化流程失败。
具体位置与上下文：
从日志可以看出，系统正在进行IRIS迭代的查询优化流程，当尝试对查询"What kind of car does Evan drive?"进行优化时，后端服务（可能是DMXAPI平台）未能在预期时间内响应，触发了超时机制。超时后，查询优化被终止，但后续的检索和生成流程仍然继续并成功了。
3. 💡 解决方案
该错误属于服务端响应超时，客户端无法直接修复。但可以通过调整客户端配置来缓解：
``代码语言
// 增加HTTP请求超时时间配置
import httpx
client = httpx.Client(
timeout=60.0, // 将超时时间从默认值增加到60秒
base_url="https://www.dmxapi.com"
)
// 或者在使用async请求时
timeout = httpx.Timeout(
connect=30.0,
read=60.0,
write=30.0,
pool=30.0
)
``
4. 🛡️ 预防措施
- 合理设置超时时间：根据网络环境和服务响应复杂度，适当调整超时时间阈值，避免默认超时时间过短
- 添加重试机制：为HTTP请求配置自动重试策略，在首次超时后自动重试，提高请求成功率
- 监控与告警：建立API响应时间监控，当连续出现超时问题时及时告警，便于排查服务端性能问题
- 异步请求优化：对于并行的多个请求，使用异步方式并发处理，减少整体等待时间
