用户创建知识库流程概述
用户登录Coze Studio↓点击"资源库"菜单↓LibraryPage 组件加载↓点击右上角"+"按钮↓LibraryHeader 显示创建菜单↓点击"知识库"选项↓openCreateKnowledgeModal() 触发↓CreateKnowledgeModalV2 弹窗显示↓用户选择知识库格式类型（文本/表格/图片）↓用户输入知识库名称（name字段）↓用户输入知识库描述（description字段）↓用户选择数据导入类型和上传图标↓表单验证（名称必填，描述可选）↓用户点击"创建"或"创建并导入"按钮↓createDataset() 触发↓KnowledgeApi.CreateDataset() 调用↓后端创建新知识库资源↓onFinish() 处理成功响应↓导航到知识库详情页面（可选择是否进入上传页面）↓刷新资源库列表
该流程包含多层验证和处理：
- 前端表单验证：通过Form组件进行名称等必填字段验证
- 知识库类型选择：支持文本、表格、图片三种格式类型
- API调用：使用KnowledgeApi.CreateDataset API处理知识库创建
- 成功处理：创建成功后可选择直接进入上传页面或知识库详情页面
- 状态管理：通过useKnowledgeConfig Hook管理弹窗状态和数据流
整个流程确保了知识库创建的便捷性和用户体验的流畅性。
核心组件实现
组件层次结构
知识库创建功能涉及多个层次的组件：
- LibraryPage组件：资源库主页面
- BaseLibraryPage组件：资源库核心逻辑
- LibraryHeader组件：包含创建按钮的头部
- CreateKnowledgeModalV2组件：知识库配置弹窗
- CozeKnowledgeAddTypeContent组件：知识库表单组件
1. 资源库入口组件（LibraryPage）
文件位置：frontend/packages/studio/workspace/entry-adapter/src/pages/library/index.tsx
作为资源库的适配器组件，整合各种资源配置：
import { type FC, useRef } from 'react';import {BaseLibraryPage,useDatabaseConfig,usePluginConfig,useWorkflowConfig,usePromptConfig,useKnowledgeConfig,
} from '@coze-studio/workspace-base/library';export const LibraryPage: FC<{ spaceId: string }> = ({ spaceId }) => {const basePageRef = useRef<{ reloadList: () => void }>(null);const configCommonParams = {spaceId,reloadList: () => {basePageRef.current?.reloadList();},};const { config: pluginConfig, modals: pluginModals } =usePluginConfig(configCommonParams);const { config: workflowConfig, modals: workflowModals } =useWorkflowConfig(configCommonParams);const { config: knowledgeConfig, modals: knowledgeModals } =useKnowledgeConfig(configCommonParams);const { config: promptConfig, modals: promptModals } =usePromptConfig(configCommonParams);const { config: databaseConfig, modals: databaseModals } =useDatabaseConfig(configCommonParams);return (<><BaseLibraryPagespaceId={spaceId}ref={basePageRef}entityConfigs={[pluginConfig,workflowConfig,knowledgeConfig,promptConfig,databaseConfig,]}/>{pluginModals}{workflowModals}{promptModals}{databaseModals}{knowledgeModals}</>);
};<ResultModalvisible={!!successData}data={successData}onOk={refresh}/></>);
};
设计亮点：
- 状态集中管理：通过
usePatOperationHook统一管理组件状态 - 组件解耦：各子组件职责明确，通过props进行通信
- 数据流清晰：单向数据流，状态变更可追踪
2. 资源库核心组件（BaseLibraryPage）
文件位置：frontend/packages/studio/workspace/entry-base/src/pages/library/index.tsx
负责资源库的核心展示逻辑：
import { forwardRef, useImperativeHandle } from 'react';import classNames from 'classnames';
import { useInfiniteScroll } from 'ahooks';
import { I18n } from '@coze-arch/i18n';
import {Table,Select,Search,Layout,Cascader,Space,
} from '@coze-arch/coze-design';
import { renderHtmlTitle } from '@coze-arch/bot-utils';
import { EVENT_NAMES, sendTeaEvent } from '@coze-arch/bot-tea';
import {type ResType,type LibraryResourceListRequest,type ResourceInfo,
} from '@coze-arch/idl/plugin_develop';
import { PluginDevelopApi } from '@coze-arch/bot-api';import { type ListData, type BaseLibraryPageProps } from './types';
import { LibraryHeader } from './components/library-header';export const BaseLibraryPage = forwardRef<{ reloadList: () => void },BaseLibraryPageProps
>(({ spaceId, isPersonalSpace = true, entityConfigs }, ref) => {const { params, setParams, resetParams, hasFilter, ready } =useCachedQueryParams({spaceId,});const listResp = useInfiniteScroll<ListData>(async prev => {if (!ready) {return {list: [],nextCursorId: undefined,hasMore: false,};}const resp = await PluginDevelopApi.LibraryResourceList(entityConfigs.reduce<LibraryResourceListRequest>((res, config) => config.parseParams?.(res) ?? res,{...params,cursor: prev?.nextCursorId,space_id: spaceId,size: LIBRARY_PAGE_SIZE,},),);return {list: resp?.resource_list || [],nextCursorId: resp?.cursor,hasMore: !!resp?.has_more,};},{reloadDeps: [params, spaceId],},);useImperativeHandle(ref, () => ({reloadList: listResp.reload,}));return (<LayoutclassName={s['layout-content']}title={renderHtmlTitle(I18n.t('navigation_workspace_library'))}><Layout.Header className={classNames(s['layout-header'], 'pb-0')}><div className="w-full"><LibraryHeader entityConfigs={entityConfigs} />{/* 过滤器组件 */}</div></Layout.Header><Layout.Content>{/* 表格和列表内容 */}</Layout.Content></Layout>);}
);
3. 资源库头部组件（LibraryHeader）
文件位置：frontend/packages/studio/workspace/entry-base/src/pages/library/components/library-header.tsx
包含创建资源的入口按钮：
import React from 'react';import { I18n } from '@coze-arch/i18n';
import { IconCozPlus } from '@coze-arch/coze-design/icons';
import { Button, Menu } from '@coze-arch/coze-design';import { type LibraryEntityConfig } from '../types';export const LibraryHeader: React.FC<{entityConfigs: LibraryEntityConfig[];
}> = ({ entityConfigs }) => (<div className="flex items-center justify-between mb-[16px]"><div className="font-[500] text-[20px]">{I18n.t('navigation_workspace_library')}</div><Menuposition="bottomRight"className="w-120px mt-4px mb-4px"render={<Menu.SubMenu mode="menu">{entityConfigs.map(config => config.renderCreateMenu?.() ?? null)}</Menu.SubMenu>}><Buttontheme="solid"type="primary"icon={<IconCozPlus />}data-testid="workspace.library.header.create">{I18n.t('library_resource')}</Button></Menu></div>
);
4. 知识库配置Hook（useKnowledgeConfig）
文件位置：frontend/packages/studio/workspace/entry-base/src/pages/library/hooks/use-entity-configs/use-knowledge-config.tsx
管理知识库创建和编辑的状态：
import { useNavigate } from 'react-router-dom';import { useRequest } from 'ahooks';
import { useCreateKnowledgeModalV2 } from '@coze-data/knowledge-modal-adapter';
import {ActionKey,type ResourceInfo,ResType,
} from '@coze-arch/idl/plugin_develop';
import { DatasetStatus } from '@coze-arch/idl/knowledge';
import { I18n, type I18nKeysNoOptionsType } from '@coze-arch/i18n';
import { IconCozClock, IconCozKnowledge } from '@coze-arch/coze-design/icons';
import { Menu, Switch, Tag, Toast, Table } from '@coze-arch/coze-design';
import { KnowledgeApi } from '@coze-arch/bot-api';
import { safeJSONParse } from '@coze-agent-ide/space-bot/util';import { BaseLibraryItem } from '../../components/base-library-item';
import DocDefaultIcon from '../../assets/doc_default_icon.png';
import { type UseEntityConfigHook } from './types';const { TableAction } = Table;/*** Knowledge base tags:* 0-text* 1-table* 2-image* */
const knowledgeSubTypeTextMap: Record<number, I18nKeysNoOptionsType> = {0: 'library_filter_tags_text',1: 'library_filter_tags_table',2: 'library_filter_tags_image',
};export const useKnowledgeConfig: UseEntityConfigHook = ({spaceId,reloadList,getCommonActions,
}) => {const navigate = useNavigate();const {modal: createKnowledgeModal,open: openCreateKnowledgeModal,close: closeCreateKnowledgeModal,} = useCreateKnowledgeModalV2({onFinish: (datasetID, unitType, shouldUpload) => {navigate(`/space/${spaceId}/knowledge/${datasetID}${shouldUpload ? '/upload' : ''}?type=${unitType}&from=create`,);closeCreateKnowledgeModal();},});// deleteconst { run: delKnowledge } = useRequest((datasetId: string) =>KnowledgeApi.DeleteDataset({dataset_id: datasetId,}),{manual: true,onSuccess: () => {reloadList();Toast.success(I18n.t('Delete_success'));},},);return {modals: <>{createKnowledgeModal}</>,config: {typeFilter: {label: I18n.t('library_resource_type_knowledge'),value: ResType.Knowledge,},renderCreateMenu: () => (<Menu.Itemdata-testid="workspace.library.header.create.knowledge"icon={<IconCozKnowledge />}onClick={openCreateKnowledgeModal}>{I18n.t('library_resource_type_knowledge')}</Menu.Item>),target: [ResType.Knowledge],onItemClick: (item: ResourceInfo) => {navigate(`/space/${spaceId}/knowledge/${item.res_id}?from=library`);},renderItem: item => (<BaseLibraryItemresourceInfo={item}defaultIcon={DocDefaultIcon}tag={<>{safeJSONParse(item.biz_extend?.processing_file_id_list)?.length ? (<Tagdata-testid="workspace.library.item.tag"color="brand"size="mini"className="flex-shrink-0 flex-grow-0"prefixIcon={<IconCozClock />}>{I18n.t('library_filter_tags_processing')}</Tag>) : null}{item.res_sub_type !== undefined &&knowledgeSubTypeTextMap[item.res_sub_type] ? (<Tagdata-testid="workspace.library.item.tag"color="brand"size="mini"className="flex-shrink-0 flex-grow-0">{I18n.t(knowledgeSubTypeTextMap[item.res_sub_type])}</Tag>) : null}</>}/>),renderActions: (item: ResourceInfo) => {const deleteDisabled = !item.actions?.find(action => action.key === ActionKey.Delete,)?.enable;const deleteProps = {disabled: deleteDisabled,deleteDesc: I18n.t('library_delete_desc'),handler: () => {delKnowledge(item.res_id || '');},};return (<TableActiondeleteProps={deleteProps}actionList={getCommonActions?.(item) ?? []}/>);},},};
};
5. 知识库配置弹窗（useCreateKnowledgeModalV2）
文件位置：frontend/packages/data/knowledge/knowledge-modal-adapter/src/create-knowledge-modal-v2/scenes/base/index.tsx
知识库创建的主要Hook和界面：
import { useRef, useState } from 'react';import { useDataModalWithCoze } from '@coze-data/utils';
import { useDataNavigate } from '@coze-data/knowledge-stores';
import { UnitType } from '@coze-data/knowledge-resource-processor-core';
import {CozeKnowledgeAddTypeContent,type CozeKnowledgeAddTypeContentFormData,
} from '@coze-data/knowledge-modal-base/create-knowledge-modal-v2';
import { KnowledgeE2e } from '@coze-data/e2e';
import { I18n } from '@coze-arch/i18n';
import { Button, Form, LoadingButton } from '@coze-arch/coze-design';
import { useSpaceStore } from '@coze-arch/bot-studio-store';
import { FormatType } from '@coze-arch/bot-api/knowledge';
import { KnowledgeApi } from '@coze-arch/bot-api';export interface UseCreateKnowledgeModalParams {projectID?: string;onFinish?: (datasetId: string, type: UnitType, shouldUpload: boolean) => void;beforeCreate?: (shouldUpload: boolean) => void;
}export const useCreateKnowledgeModalV2 = (params: UseCreateKnowledgeModalParams = {},
) => {const { onFinish, beforeCreate, projectID } = params;const formRef = useRef<Form<CozeKnowledgeAddTypeContentFormData>>(null);const [currentFormatType, setCurrentFormatType] = useState(FormatType.Text);const spaceId = useSpaceStore(store => store.getSpaceId());const resourceNavigate = useDataNavigate();const [unitType, setUnitType] = useState<UnitType>(UnitType.TEXT_DOC);const createDataset = async () => {await formRef.current?.formApi.validate();const { dataset_id: datasetId } = await KnowledgeApi.CreateDataset({project_id: projectID || undefined,name: formRef.current?.formApi.getValue('name'),format_type: currentFormatType,description: formRef.current?.formApi.getValue('description'),icon_uri: formRef.current?.formApi.getValue('icon_uri')?.[0].uid,space_id: spaceId || undefined,});return datasetId;};const { open, close, modal } = useDataModalWithCoze({title: (<div data-testid={KnowledgeE2e.CreateKnowledgeModalTitle}>{I18n.t('datasets_model_create_title')}</div>),centered: true,onCancel: () => {close();},footer: (<div className="flex w-full justify-end"><Buttoncolor="primary"onClick={() => {close();}}>{I18n.t('cancel')}</Button><LoadingButtoncolor="primary"onClick={async () => {beforeCreate?.(false);const datasetId = await createDataset();if (onFinish) {onFinish(datasetId || '', unitType, false);} else {resourceNavigate.toResource?.('knowledge', datasetId);}}}>{I18n.t('kl_write_108')}</LoadingButton><LoadingButtondata-testid={KnowledgeE2e.CreateKnowledgeModalSubmitAndImportButton}color="primary"onClick={async () => {beforeCreate?.(true);const datasetId = await createDataset();if (onFinish) {onFinish(datasetId || '', unitType, true);} else {resourceNavigate.upload?.({ type: unitType });}}}>{I18n.t('kl_write_109')}</LoadingButton></div>),});return {modal: modal(<Form<CozeKnowledgeAddTypeContentFormData>ref={formRef}showValidateIcon={false}><CozeKnowledgeAddTypeContentonImportKnowledgeTypeChange={setUnitType}onSelectFormatTypeChange={setCurrentFormatType}/></Form>,),open: () => {setCurrentFormatType(FormatType.Text);open();},close,};
};设计亮点：

useCreateKnowledgeModalV2Hook统一管理知识库创建状态 - 组件解耦：各子组件职责明确，通过props进行通信
- 数据流清晰：单向数据流，状态变更可追踪
- 用户体验优化：支持两种创建模式（仅创建/创建并导入）
- 表单验证完善：支持表单验证和实时反馈
6. 知识库表单组件（CozeKnowledgeAddTypeContent）
文件位置：frontend/packages/data/knowledge/knowledge-modal-base/src/create-knowledge-modal-v2/features/add-type-content/coze-knowledge/index.tsx
知识库创建表单的核心组件：
import { useEffect, useState } from 'react';import { CozeFormTextArea, CozeInputWithCountField } from '@coze-data/utils';
import { UnitType } from '@coze-data/knowledge-resource-processor-core';
import { KnowledgeE2e } from '@coze-data/e2e';
import { PictureUpload } from '@coze-common/biz-components/picture-upload';
import { I18n } from '@coze-arch/i18n';
import { FormatType } from '@coze-arch/bot-api/knowledge';
import { type Icon } from '@coze-arch/bot-api/knowledge';
import { FileBizType, IconType } from '@coze-arch/bot-api/developer_api';
import { KnowledgeApi } from '@coze-arch/bot-api';
import { useFormApi } from '@coze-arch/coze-design';export interface CozeKnowledgeAddTypeContentFormData {name: string;icon_uri?: Array<{url: string;uri: string;uid: string;isDefault?: boolean;}>;format_type: FormatType;description: string;
}export const CozeKnowledgeAddTypeContent = (params: AddTypeContentProps) => {const { onImportKnowledgeTypeChange, onSelectFormatTypeChange } = params;const formApi = useFormApi<CozeKnowledgeAddTypeContentFormData>();const [currentFormatType, setCurrentFormatType] = useState(FormatType.Text);const [iconInfoGenerate, setIconInfoGenerate] = useState<{name: string;desc: string;}>({name: '',desc: '',});const [coverIcon, setCoverIcon] = useState<Icon | undefined>({uri: '',url: '',});const fetchIcon = async (formatType: FormatType) => {const { icon } = await KnowledgeApi.GetIcon({format_type: formatType,});setCoverIcon(icon);const currentCover = formApi.getValue('icon_uri');if (!currentCover || currentCover[0]?.isDefault) {formApi.setValue('icon_uri', [{url: icon?.url ?? '',uri: icon?.uri ?? '',uid: icon?.uri ?? '',isDefault: true,},]);}};const [unitType, setUnitType] = useState<UnitType>(UnitType.TEXT_DOC);useEffect(() => {fetchIcon(currentFormatType);if (currentFormatType === FormatType.Text) {setUnitType(UnitType.TEXT_DOC);} else if (currentFormatType === FormatType.Table) {setUnitType(UnitType.TABLE_DOC);} else if (currentFormatType === FormatType.Image) {setUnitType(UnitType.IMAGE_FILE);}}, [currentFormatType]);return (<div data-testid={KnowledgeE2e.CreateKnowledgeModal}><SelectFormatTypefield="format_type"noLabelonChange={(type: FormatType) => {setCurrentFormatType(type);formApi.setValue('format_type', type);onSelectFormatTypeChange?.(type);}}/><CozeInputWithCountFielddata-testid={KnowledgeE2e.CreateKnowledgeModalNameInput}field="name"label={I18n.t('datasets_model_create_name')}maxLength={100}rules={[{required: true,whitespace: true,message: I18n.t('dataset-name-empty-tooltip'),},{pattern: /^[^"'`\\]+$/,message: I18n.t('dataset-name-has-wrong-word-tooltip'),},]}placeholder={I18n.t('datasets_model_create_name_placeholder')}/><CozeFormTextAreafield="description"data-testid={KnowledgeE2e.CreateKnowledgeModalDescInput}label={I18n.t('datasets_model_create_description')}autosize={{ minRows: 1, maxRows: 2 }}maxCount={2000}maxLength={2000}placeholder={I18n.t('datasets_model_create_description_placeholder')}/><ImportKnowledgeSourceSelectformatType={currentFormatType}initValue={unitType}onChange={setUnitType}/><PictureUploadlabel={I18n.t('datasets_model_create_avatar')}field="icon_uri"testId={KnowledgeE2e.CreateKnowledgeModalAvatarUploader}fileBizType={FileBizType.BIZ_DATASET_ICON}iconType={IconType.Dataset}generateInfo={iconInfoGenerate}/></div>);
