查询记录

获取查询记录列表

列出知识库的查询记录，最新的在前。每次调用运行查询，流一建立就会保存一条记录，之后失败的运行也不例外；但客户端断开连接，或运行以 RETRIEVAL_EXECUTION_LEASE_LOST 失败时，不保存记录。

列表除了包含当前密钥产生的记录，还包含工作流、Agent、MCP 客户端和其他 API 密钥产生的记录。即使为每个租户分别使用一个密钥，列表也不会只显示该租户的运行。在 Dify 中进行的检索测试从不列出。

source 是唯一的筛选条件。如需日后再次定位某次运行，在查询时记下运行查询返回的 x-query-run-id 响应头。

如何结合查看一次运行的分段、冲突和缺失分段，详见排查回答。

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

knowledge_base_id

string<uuid>

required

知识库 ID：即知识库 API 访问对话框中所示服务 API 端点的最后一段（…/knowledge-fs/spaces/<knowledge base ID>），也是地址栏中 /datasets/new/ 之后的那一段。

Query Parameters

cursor

string

游标，取自上一页的 next_cursor。

Required string length: 1 - 1000

source

enum<string>

只返回某一类调用方产生的记录：service_api 表示 API 密钥，workflow 表示工作流节点，agent 或 mcp 表示相应的客户端。可以传 retrieval_test，但通过此 API 不会返回任何记录。

Available options:

retrieval_test,

workflow,

service_api,

agent,

mcp

limit

integer

default:50

每页记录数。

Required range: 1 <= x <= 100

Response

一页查询记录。

data

object[]

查询记录，最新的在前。

Show child attributes

next_cursor

string | null

下一页的游标，最后一页时为 null。将其作为 cursor 传回。
