Authorizations

Authorization · string · header · required

每个请求都通过 API Key 认证：Authorization: Bearer {API_KEY}。应用接口使用应用 API Key，知识库接口使用知识库 API Key（快速开始）。

API Key 应保存在服务端，切勿嵌入客户端代码。缺失或无效的 Key 会返回 HTTP 401（unauthorized）。

Path Parameters

dataset_id · string<uuid> · required

知识库 ID。从 获取知识库列表 获取。

node_id · string · required

要运行的数据源节点 ID，来自 获取数据源插件列表。

Body

application/json

inputs · object · required

数据源节点的输入变量。

datasource_type · enum<string> · required

数据源类型。

Available options: online_document, local_file, website_crawl, online_drive

is_published · boolean · required

是否运行节点的已发布版本，而非草稿版本。

credential_id · string | null

用于向数据源认证的凭证 ID，来自 获取数据源插件列表 的 credentials 数组。

Response
