# Workflow 应用 API

Workflow 应用无会话支持，适合用于翻译/文章写作/总结 AI 等等。

<div>
  ### Base URL
  <CodeGroup title="Code" targetCode={props.appDetail.api_base_url} />

  ### Authentication

  Service API 使用 `API-Key` 进行鉴权。
  <i>**强烈建议开发者把 `API-Key` 放在后端存储，而非分享或者放在客户端存储，以免 `API-Key` 泄露，导致财产损失。**</i>
  所有 API 请求都应在 **`Authorization`** HTTP Header 中包含您的 `API-Key`，如下所示：

  <CodeGroup title="Code" targetCode='Authorization: Bearer {API_KEY}' />
</div>

---

<Heading
  url='/workflows/run'
  method='POST'
  title='执行 Workflow'
  name='#Execute-Workflow'
/>
<Row>
  <Col>
    执行 workflow，没有已发布的 workflow，不可执行。

    ### Request Body
      - `inputs` (object) Required
        允许传入 App 定义的各变量值。
        inputs 参数包含了多组键值对（Key/Value pairs），每组的键对应一个特定变量，每组的值则是该变量的具体值。变量可以是文件列表类型。
        文件列表类型变量适用于传入文件结合文本理解并回答问题，仅当模型支持该类型文件解析能力时可用。如果该变量是文件列表类型，该变量对应的值应是列表格式，其中每个元素应包含以下内容：
          - `type` (string) 支持类型：
            - `document` 具体类型包含：'TXT', 'MD', 'MARKDOWN', 'PDF', 'HTML', 'XLSX', 'XLS', 'DOCX', 'CSV', 'EML', 'MSG', 'PPTX', 'PPT', 'XML', 'EPUB'
            - `image` 具体类型包含：'JPG', 'JPEG', 'PNG', 'GIF', 'WEBP', 'SVG'
            - `audio` 具体类型包含：'MP3', 'M4A', 'WAV', 'WEBM', 'AMR'
            - `video` 具体类型包含：'MP4', 'MOV', 'MPEG', 'MPGA'
            - `custom` 具体类型包含：其他文件类型
          - `transfer_method` (string) 传递方式，`remote_url` 图片地址 / `local_file` 上传文件
          - `url` (string) 图片地址（仅当传递方式为 `remote_url` 时）
          - `upload_file_id` (string)  上传文件 ID（仅当传递方式为 `local_file` 时）
      - `response_mode` (string) Required
        返回响应模式，支持：
        - `streaming` 流式模式（推荐）。基于 SSE（**[Server-Sent Events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events)**）实现类似打字机输出方式的流式返回。
        - `blocking` 阻塞模式，等待执行完毕后返回结果。（请求若流程较长可能会被中断）。
        <i>由于 Cloudflare 限制，请求会在 100 秒超时无返回后中断。</i>
      - `user` (string) Required
        用户标识，用于定义终端用户的身份，方便检索、统计。
        由开发者定义规则，需保证用户标识在应用内唯一。API 无法访问 WebApp 创建的会话。
      - `files` (array[object]) 可选
      - `trace_id` (string) Optional
        链路追踪ID。适用于与业务系统已有的trace组件打通，实现端到端分布式追踪等场景。如果未指定，系统将自动生成 `trace_id`。支持以下三种方式传递，具体优先级依次为：
        1. Header：推荐通过 HTTP Header `X-Trace-Id` 传递，优先级最高。
        2. Query 参数：通过 URL 查询参数 `trace_id` 传递。
        3. Request Body：通过请求体字段 `trace_id` 传递（即本字段）。

    ### Response

    ### Blocking Mode
    阻塞模式可能返回已完成的工作流结果，也可能返回暂停中的工作流结果。

    当执行因 Human-in-the-Loop 暂停时，响应仍然会包含 `workflow_run_id` 和 `task_id`，但 `data.status` 会变为 `paused`。
    暂停响应还会包含 `paused_nodes` 和 `reasons`。对于 `human_input_required`，每个 reason 都会包含 `form_id` 和 `expiration_time`。

    流式模式同样可能因为 Human-in-the-Loop 而暂停。此时 SSE 流会先返回 `human_input_required`，随后返回 `workflow_paused`。

<Heading

  method='POST'
  title='执行指定版本 Workflow'
  name='#Execute-Specific-Workflow'
/>
<Row>
  <Col>
    执行指定版本的工作流，通过路径参数指定工作流ID。

    ### Path
    - `workflow_id` (string) Required 工作流ID，用于指定特定版本的工作流

      获取方式：在版本历史界面，点击每个版本条目右侧的复制图标即可复制完整的工作流 ID。

    ### Request Body
      - `inputs` (object) Required
        允许传入 App 定义的各变量值。
        inputs 参数包含了多组键值对（Key/Value pairs），每组的键对应一个特定变量，每组的值则是该变量的具体值。变量可以是文件列表类型。
        文件列表类型变量适用于传入文件结合文本理解并回答问题，仅当模型支持该类型文件解析能力时可用。如果该变量是文件列表类型，该变量对应的值应是列表格式，其中每个元素应包含以下内容：
          - `type` (string) 支持类型：
            - `document` 具体类型包含：'TXT', 'MD', 'MARKDOWN', 'MDX', 'PDF', 'HTML', 'XLSX', 'XLS', 'VTT', 'PROPERTIES', 'DOC', 'DOCX', 'CSV', 'EML', 'MSG', 'PPTX', 'PPT', 'XML', 'EPUB'
            - `image` 具体类型包含：'JPG', 'JPEG', 'PNG', 'GIF', 'WEBP', 'SVG'
            - `audio` 具体类型包含：'MP3', 'M4A', 'WAV', 'WEBM', 'MPGA'
            - `video` 具体类型包含：'MP4', 'MOV', 'MPEG', 'WEBM'
            - `custom` 具体类型包含：其他文件类型
          - `transfer_method` (string)  传递方式:
            - `remote_url`: 文件地址。
            - `local_file`: 上传文件。
          - `url` 文件地址。（仅当传递方式为 `remote_url` 时）。
          - `upload_file_id` 上传文件 ID。（仅当传递方式为 `local_file `时）。
          
      - `response_mode` (string) Required
        返回响应模式，支持：
        - `streaming` 流式模式（推荐）。基于 SSE（**[Server-Sent Events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events)**）实现类似打字机输出方式的流式返回。
        - `blocking` 阻塞模式，等待执行完毕后返回结果。（请求若流程较长可能会被中断）。
        <i>由于 Cloudflare 限制，请求会在 100 秒超时无返回后中断。</i>
      - `user` (string) Required
        用户标识，用于定义终端用户的身份，方便检索、统计。
        由开发者定义规则，需保证用户标识在应用内唯一。API 无法访问 WebApp 创建的会话。
      - `files` (array[object]) 可选
      - `trace_id` (string) Optional
        链路追踪ID。适用于与业务系统已有的trace组件打通，实现端到端分布式追踪等场景。如果未指定，系统将自动生成 `trace_id`。支持以下三种方式传递，具体优先级依次为：
        1. Header：推荐通过 HTTP Header `X-Trace-Id` 传递，优先级最高。
        2. Query 参数：通过 URL 查询参数 `trace_id` 传递。
        3. Request Body：通过请求体字段 `trace_id` 传递（即本字段）。

    ### Response
    当 `response_mode` 为 `blocking` 时，返回 CompletionResponse object。
    当 `response_mode` 为 `streaming`时，返回 ChunkCompletionResponse object 流式序列。

    ### CompletionResponse
    返回完整的 App 结果，`Content-Type` 为 `application/json` 。
    - `workflow_run_id` (string) workflow 执行 ID
    - `task_id` (string) 任务 ID，用于请求跟踪和下方的停止响应接口
    - `data` (object) 详细内容
      - `id` (string) workflow 执行 ID
      - `workflow_id` (string) 关联 Workflow ID
      - `status` (string) 执行状态, `running` / `succeeded` / `failed` / `stopped`
      - `outputs` (json) Optional 输出内容
      - `error` (string) Optional 错误原因
      - `elapsed_time` (float) Optional 耗时(s)
      - `total_tokens` (int) Optional 总使用 tokens
      - `total_steps` (int) 总步数（冗余），默认 0
      - `created_at` (timestamp) 开始时间
      - `finished_at` (timestamp) 结束时间

    ### ChunkCompletionResponse
    返回 App 输出的流式块，`Content-Type` 为 `text/event-stream`。
    每个流式块均为 data: 开头，块之间以 `\n\n` 即两个换行符分隔，如下所示：
    <CodeGroup>
    ```streaming {{ title: 'Response' }}
    data: {"event": "text_chunk", "workflow_run_id": "b85e5fc5-751b-454d-b14e-dc5f240b0a31", "task_id": "bd029338-b068-4d34-a331-fc85478922c2", "data": {"text": "\u4e3a\u4e86", "from_variable_selector": ["1745912968134", "text"]}}\n\n
    ```
    </CodeGroup>
    流式块中根据 `event` 不同，结构也不同，包含以下类型：
    - `event: workflow_started` workflow 开始执行
      - `task_id` (string) 任务 ID，用于请求跟踪和下方的停止响应接口
      - `workflow_run_id` (string) workflow 执行 ID
      - `event` (string) 固定为 `workflow_started`
      - `data` (object) 详细内容
        - `id` (string) workflow 执行 ID
        - `workflow_id` (string) 关联 Workflow ID
