-## LLMService 新特性 - -通过此次重构，现在可以利用 LLMService 的以下特性： - -1. **API Key 负载均衡**: 自动在多个 API key 之间分配请求 -2. **客户端缓存**: 避免重复创建客户端实例 -3. **统一接口**: 所有 provider 使用相同的调用方式 -4. **集中配置**: API keys 在 `config/api_keys.json` 中统一管理 -5. **使用统计**: 可通过 `get_api_keys_status()` 查看各 provider 的使用情况 - -## 测试建议 - -建议在部署前进行以下测试： - -1. **单元测试**: 使用 mock 测试各 provider 的流式响应处理 -2. **集成测试**: 使用真实 API key 测试端到端流程 -3. **负载测试**: 验证多 API key 的负载均衡功能 -4. **错误场景**: 测试 API key 失效、Token 超限等异常情况 - -## 结论 - -✅ 重构成功完成，所有接口的出入参和流式行为保持不变。 -✅ 代码结构更清晰，维护性更好。 -✅ 为未来的扩展（如更多 provider、更复杂的负载均衡策略）打下了良好基础。 diff --git a/api/simple_chat.py b/api/simple_chat.py index 5a2a01399..d3ce39edd 100644 --- a/api/simple_chat.py +++ b/api/simple_chat.py @@ -340,12 +340,12 @@ async def response_stream(): model=request.model ): # Post-process for Ollama to remove thinking tags -
