Python AI 服务对外提供的接口契约（Provider）。
|
|||
|
|
|
|||
|
|
目标：100% 覆盖并对齐 Java 端 Consumer-First 依赖契约 `java/openapi.deps.yaml`。
|
|||
|
|
- 路径与方法必须一致
|
|||
|
|
- non-streaming JSON 响应 schema 必须一致（reply/confidence/shouldTransfer 等）
|
|||
|
|
|
|||
|
|
额外扩展：支持 SSE 流式输出（Accept: text/event-stream）。

|

|
|
|

|
|
non-streaming：返回 application/json（ChatResponse）。
|
|||
|
|
streaming：当请求头包含 `Accept: text/event-stream` 时，以 SSE 推送事件流。
|
|||
|
|
|

|
|
覆盖验收标准（来自 Java 侧契约描述）：
|
|||
|
|
- AC-MCA-04: 主框架通过 HTTP POST 调用 AI 服务
|
|||
|
|
- AC-MCA-05: 响应包含 reply、confidence、shouldTransfer 字段
|
|||
|
|
- AC-MCA-06: AI 服务不可用时的降级处理（主框架侧实现）
|
|||
|
|
- AC-MCA-07: 超时处理（主框架侧实现）

SSE 事件流（按行文本）。事件模型：
|
|||
|
|
|
|||
|
|
1) event: message
|
|||
|
|
- data: {"delta": "..."}
|
|||
|
|
- 返回时机：模型生成过程中多次发送，用于增量渲染。
|
|||
|
|
|
|||
|
|
2) event: final
|
|||
|
|
- data: ChatResponse（完整结构化结果，字段至少包含 reply/confidence/shouldTransfer）
|
|||
|
|
- 返回时机：生成结束时发送一次，随后关闭连接。
|
|||
|
|
|
|||
|
|
3) event: error
|
|||
|
|
- data: ErrorResponse（结构化错误，至少 code/message，可含 details）
|
|||
|
|
- 返回时机：发生错误时发送一次，随后关闭连接。
|
|||
|
|
|
