# 工作流编排对话型应用 API

对话应用支持会话持久化，可将之前的聊天记录作为上下文进行回答，可适用于聊天/客服 AI 等。

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

  ### 鉴权

  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='/chat-messages'
  method='POST'
  title='发送对话消息'
  name='#Create-Chat-Message'
/>
<Row>
  <Col>
    创建会话消息。

    ### Request Body

    <Properties>
      <Property name='query' type='string' key='query'>
        用户输入/提问内容。
      </Property>
      <Property name='inputs' type='object' key='inputs'>
        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。
        如果变量是文件类型，请指定一个包含以下 `files` 中所述键的对象。
        默认 `{}`
      </Property>
      <Property name='response_mode' type='string' key='response_mode'>
        - `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>
      </Property>
      <Property name='user' type='string' key='user'>
        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。服务 API 不会共享 WebApp 创建的对话。
      </Property>
      <Property name='conversation_id' type='string' key='conversation_id'>
      （选填）会话 ID，需要基于之前的聊天记录继续对话，必须传之前消息的 conversation_id。
      </Property>
      <Property name='files' type='array[object]' key='files'>
          文件列表，适用于传入文件结合文本理解并回答问题，仅当模型支持 Vision/Video 能力时可用。

            - `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）。
      </Property>
      <Property name='auto_generate_name' type='bool' key='auto_generate_name'>
      （选填）自动生成标题，默认 `true`。 若设置为 `false`，则可通过调用会话重命名接口并设置 `auto_generate` 为 `true` 实现异步生成标题。
      </Property>
      <Property name='workflow_id' type='string' key='workflow_id'>
      （选填）工作流ID，用于指定特定版本，如果不提供则使用默认的已发布版本。
      </Property>
      <Property name='trace_id' type='string' key='trace_id'>
      （选填）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，系统会自动生成<code>trace_id</code>。支持以下三种方式传递，具体优先级依次为：<br/>
        - Header：通过 HTTP Header <code>X-Trace-Id</code> 传递，优先级最高。<br/>
        - Query 参数：通过 URL 查询参数 <code>trace_id</code> 传递。<br/>
        - Request Body：通过请求体字段 <code>trace_id</code> 传递（即本字段）。<br/>
      </Property>

    ### Response
    <Properties>
    当 `response_mode` 为 `blocking` 时，返回 ChatCompletionResponse object。
    当 `response_mode` 为 `streaming`时，返回 ChunkChatCompletionResponse object 流式序列。

    ### ChatCompletionResponse

    返回完整的 App 结果，`Content-Type` 为 `application/json`。

    ### ChunkChatCompletionResponse
    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": "message", "task_id": "900bbd43-dc0b-4383-a372-aa6e6c414227", "id": "663c5084-a254-4040-8ad3-51f2a3c1a77c", "answer": "Hi", "created_at": 1705398420}\n\n
    ```

    ### 阻塞模式
    阻塞模式可能返回普通聊天响应，也可能返回暂停中的工作流响应。

    当 Advanced Chat 因 Human-in-the-Loop 暂停时，`event` 会变为 `workflow_paused`。
    响应仍然包含 `message_id`、`conversation_id`、`answer` 和 `workflow_run_id`，并且 `data` 中会新增 `paused_nodes` 和 `reasons`。
    对于 `human_input_required`，每个 reason 都会包含 `form_id` 和 `expiration_time`。

    嵌入模型的提供商和模型名称可以通过以下接口获取：v1/workspaces/current/models/model-types/text-embedding，具体见：通过 API 维护知识库。使用的 Authorization 是 Dataset 的 API Token。

      title="Request"
      tag="POST"
      label="/apps/annotation-reply/{action}"
      targetCode={`curl --location --request POST '${props.appDetail.api_base_url}/apps/annotation-reply/{action}' \\
--header 'Authorization: Bearer {api_key}' \\
--header 'Content-Type: application/json' \\
--data-raw '{
    "score_threshold": 0.9,
    "embedding_provider_name": "zhipu",
    "embedding_model_name": "embedding_3"

    ```
    </CodeGroup>
    该接口是异步执行，所以会返回一个job_id，通过查询job状态接口可以获取到最终的执行结果。
