# 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}>
    ```javascript
    ```
  </CodeGroup>

  ### 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">
    ```javascript
      Authorization: Bearer {API_KEY}
    ```
  </CodeGroup>
</div>

    ### 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。
        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>
        注：Agent模式下不允许blocking。
      </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。
      </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'>
          上传的文件。
          - `type` (string) 支持类型：图片 `image`（目前仅支持图片格式） 。
          - `transfer_method` (string)  传递方式:
            - `remote_url`: 图片地址。
            - `local_file`: 上传文件。
          - `url` 图片地址。（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>
    </Properties>

    ### 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

    <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
    ```
