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。

document_id

string<uuid>

required

文档 ID，从获取文档列表获取。

Response

文档。

active

object | null

当前生效的修订版本，即知识库当前提供的内容。将其 revision 传给获取分段列表，将其 document_asset_id 传给获取文档文件。没有生效的修订版本时为 null。

Show child attributes

active_revision

integer | null

生效修订版本的编号。没有生效的修订版本时为 null。

created_at

string

文档创建时间，ISO 8601 格式。

disabled_at

string | null

在 Dify 中禁用该文档的时间，ISO 8601 格式。

disabled_by_subject_id

string | null

禁用该文档的操作者的内部 ID。调用此 API 时无需使用。

enabled

boolean

在 Dify 中禁用文档后为 false。重新索引文档会跳过已禁用的文档。

string

文档 ID。文档内容更新后保持不变。

knowledge_space_id

string

知识库的内部 ID，并非路径中的知识库 ID。

latest_task

object | null

为该文档生成修订版本的最新索引任务（task_kind: document）。可用其 id 调用获取文档的索引任务跟踪该任务。没有索引任务时为 null，在更新文档元数据的响应中始终为 null。

Show child attributes

provider_item_id

string | null

从数据源导入的文档在该数据源中的条目标识，即发送给导入数据源条目的 providerItemId，或网站页面的 page_id。

row_version

integer

变更计数器。调用更新文档元数据时将其作为 expectedRowVersion 传入。更新元数据、新修订版本生效、在 Dify 中启用或禁用文档时，该值都会递增。

source_id

string | null

文档的来源数据源。上传的文件为 null。

status

string

pending（尚无生效的修订版本）、ready（已有修订版本生效）、failed（首个修订版本索引失败，且没有生效的修订版本）或 deleting。ready 的文档在后续修订版本失败时仍保持 ready。

title

string

文档标题。

updated_at

string

文档最后变更时间，ISO 8601 格式。

user_metadata

object

自定义元数据，以元数据字段名为键。可通过更新文档元数据或在 Dify 中修改。
