## 上游请求模板逐字段清单

下表由插件请求模板生成，覆盖 body、query、headers 和 multipart 文件声明中的每个字段。

| 上游位置 | 值或转换表达式 |
| --- | --- |
| `create.method` | `"POST"` |
| `create.path` | `"/api/v1/services/aigc/image-generation/generation"` |
| `create.contentType` | `"application/json"` |
| `create.body.model` | `{"$ref":"request.model"}` |
| `create.body.input.messages[0].role` | `"user"` |
| `create.body.input.messages[0].content` | `{"$concatArrays":[{"$map":{"from":{"$sortByOrder":{"$ref":"request.images"}},"as":"media","in":{"image":{"$coalesce":[{"$ref":"media.dataUrl"},{"$ref":"media.url"}]}}}},[{"text":{"$ref":"request.prompt"}}]]}` |
| `create.body.parameters.size` | `{"$omitEmpty":{"$switch":{"cases":[{"when":{"$eq":[{"$ref":"request.aspectRatio"},"1:1"]},"then":"1024*1024"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"3:4"]},"then":"960*1280"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"4:3"]},"then":"1280*960"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"2:3"]},"then":"1024*1536"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"3:2"]},"then":"1536*1024"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"9:16"]},"then":"864*1536"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"16:9"]},"then":"1536*864"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"1024x1024"]},"then":"1024*1024"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"1024x1536"]},"then":"1024*1536"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"1536x1024"]},"then":"1536*1024"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"1024x1280"]},"then":"1024*1280"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"1280x1024"]},"then":"1280*1024"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"960x1280"]},"then":"960*1280"},{"when":{"$eq":[{"$ref":"request.aspectRatio"},"1280x960"]},"then":"1280*960"}],"default":null}}}` |
| `create.body.parameters.n` | `{"$if":{"condition":{"$gt":[{"$toInt":{"$ref":"request.imageCount"}},0]},"then":{"$toInt":{"$ref":"request.imageCount"}},"else":1}}` |
| `create.body.parameters.prompt_extend` | `true` |
| `create.body.parameters.enable_thinking` | `false` |
| `create.body.parameters.negative_prompt` | `{"$omitEmpty":{"$ref":"request.providerOptions.dashscope-qwen-image.negative_prompt"}}` |
| `create.body.parameters.seed` | `{"$omitEmpty":{"$ref":"request.providerOptions.dashscope-qwen-image.seed"}}` |
| `create.body.parameters.watermark` | `{"$omitEmpty":{"$ref":"request.watermark"}}` |
| `create.headers.X-DashScope-Async` | `"enable"` |
| `poll.method` | `"GET"` |
| `poll.path` | `"/api/v1/tasks/{{taskId}}"` |
| `poll.contentType` | `"application/json"` |

## Provider 扩展键

- `providerOptions.dashscope-qwen-image.negative_prompt`
- `providerOptions.dashscope-qwen-image.seed`

动态模型或工作流允许使用文档声明的完整 `parameters/input/extra_body` 对象；该对象是协议本身的开放 schema，不会被宿主裁剪。

## 响应映射逐字段清单

| 映射位置 | 上游路径或转换表达式 |
| --- | --- |
| `response.taskId` | `{"$coalesce":[{"$ref":"response.output.task_id"},{"$ref":"response.task_id"},{"$ref":"taskId"}]}` |
| `response.status` | `{"$coalesce":[{"$ref":"response.output.task_status"},{"$ref":"response.status"},"pending"]}` |
| `response.message` | `{"$coalesce":[{"$ref":"response.output.message"},{"$ref":"response.message"}]}` |
| `response.images` | `{"$map":{"from":{"$ref":"response.output.choices.0.message.content"},"as":"item","in":{"url":{"$omitEmpty":{"$ref":"item.image"}}}}}` |
| `response.errorPaths[0]` | `"code"` |
| `response.errorPaths[1]` | `"output.code"` |
| `response.resultEphemeral` | `true` |
| `response.messagePaths[0]` | `"message"` |
| `response.messagePaths[1]` | `"output.message"` |

## 响应与错误

插件把上游 task/status/text/media/usage 映射为统一结果。临时媒体 URL 标记为 ephemeral，由宿主立即下载持久化。HTTP 错误、业务 code 和 error object 保持失败语义，不包装成成功。

## 兼容边界

百炼多模态图像端点（image-generation 异步任务）。文生图与图生图共用同一入口：不传 image 为文生图，传 1-3 张 image 为图生图。参考图通过 input.messages[].content[].image 传输（优先 Base64 data URL），不使用 OpenAI 的 /v1/images/edits multipart。size 采用“宽*高”，未登记的档位省略并由模型自动推荐；enable_thinking 固定为 false，因为官方要求非流式调用关闭思考模式。

## Manifest 完整接口定义

以下 JSON 与插件包内实际 `manifest.json` 逐字段一致，覆盖插件身份、权限、配置、鉴权、参数、校验、创建、Agent、查询、取消、结果下载、响应和 Agent 响应映射。`documentation` 字段的值就是当前完整文档；为避免文档在自身内部无限递归，JSON 中仅用等义占位文本表示正文。
