4-11: 🛠️ Refactor suggestion
Enhance demo clarity and user experience.
As a demo component, this implementation could be improved in several ways:
- Add explanatory text within the Cell to describe the purpose of a disabled uploader
- Include a default file list or preview to demonstrate how disabled state affects existing uploads
- Consider adding props like
maxCountorpreviewTypeto showcase more features even in disabled stateConsider this enhancement:
const Demo6 = () => { return ( - <Cell style={{ flexWrap: 'wrap' }}> - <Uploader disabled /> + <Cell style={{ flexWrap: 'wrap' }}> + <Cell.Description>Disabled uploader state demonstration</Cell.Description> + <Uploader + disabled + defaultFileList={[ + { + name: 'example.png', + url: 'https://example.com/example.png', + status: 'success' + } + ]} + maxCount={3} + previewType="list" + /> </Cell> ) }📝 Committable suggestion

1-22: 💡 Codebase verification
Based on the documentation files and demo content reviewed, I can now provide the final response:
Documentation improvements needed for Demo8's capture functionality
The review comment is valid. While the documentation does explain the
captureprop in the Props table, the demo itself lacks proper documentation. Here's why this needs attention:
- The documentation shows that Demo8 specifically demonstrates "直接调起摄像头" (Directly activate the camera) functionality, but the demo code lacks comments explaining this important use case.
- The current implementation with a 2-second delay is indeed not representative of real upload scenarios and lacks error handling.
- Other demos in the codebase also lack proper documentation, making this a consistent issue across demo files.
Suggested improvements:
- Add comments explaining that the
captureprop is used to directly activate the device camera on mobile devices- Include error handling in the upload function to demonstrate proper error management
- Consider adding a more realistic upload simulation or at least a comment explaining that the delay is for demonstration purposes only
🔗 Analysis chain
Consider enhancing this demo with additional documentation and error handling.
As this is a demo file showcasing the Uploader 3.0 functionality:
- Add comments explaining the purpose of the capture prop and its use cases
- Consider showing error handling scenarios
- The 2-second delay might not be representative of real upload scenarios
Let's check if other demo files include proper documentation:
Let me modify the search pattern to correctly check for documentation in demo files.
This will help us:
- Identify all demo files in the directory
- Look for both single-line and multi-line comments in these files to understand the documentation patterns
Let me try a different approach to check the content of these demo files, focusing on their structure and any existing documentation.
Let me check the documentation files to understand how the demos are documented in the component's documentation.

7-41: 💡 Codebase verification
Based on the search results, I can now provide a final response:
Consider using local assets from the repository for the demo
The search reveals that:
- The specific image URL
360buyimg.comis widely used across multiple demo files- The repository already has a dedicated assets directory at
src/sites/assets/images/with many local imagesRecommendations:
- Store demo images in
src/sites/assets/images/alongside other local assets- Create a reusable demo assets constant file to maintain URLs in one place
- Use relative imports to reference these local assets instead of external URLs
This will:
- Prevent broken demos if external resources become unavailable
- Improve load times and reliability
- Follow the existing pattern of local asset usage seen in other parts of the codebase
🔗 Analysis chain
Consider using local assets for the demo.
The demo currently uses external image URLs which could lead to broken demos if the external resource becomes unavailable.
Let's check if these image URLs are used elsewhere in the codebase:
Consider:
- Using local demo assets to prevent external dependencies
- Creating a demo assets constant file to maintain URLs in one place
- Implementing proper error handling for image loading failures
Let me try a different search approach to verify the usage of these image URLs.
I'm searching for both the URL pattern across all files and checking if there are any local image assets already present in the repository. This will help us:
- Verify if these external URLs are used elsewhere
- Check if there are existing local assets we could potentially use instead

7-40: 🛠️ Refactor suggestion
Consider improving type safety and demo clarity.
A few suggestions to enhance the demo:
- Define an enum for file status values to ensure type safety
- Use more generic/English file names for better international understanding
- Consider using different mock URLs for each file to better demonstrate variety
Here's a suggested improvement:
enum FileStatus { SUCCESS = 'success', ERROR = 'error', UPLOADING = 'uploading' } const [list, setList] = useState<FileItem[]>([ { name: 'document1.png', url: 'https://example.com/sample1.gif', status: FileStatus.SUCCESS, message: 'Upload successful', }, // ... other items with different URLs and English text ])

Several improvements could be made to the upload simulation:
- The 50% failure rate might be too high for demonstration purposes
- The error message could be more descriptive
- URL.createObjectURL creates a memory leak if not revoked
Here's the suggested fix:
async function upload(file: File) { await sleep(2000) - if (Math.random() < 0.5) { + if (Math.random() < 0.2) { // 20% failure rate + throw new Error(`Failed to upload ${file.name}: Network error`) + } + const objectUrl = URL.createObjectURL(file) + // Add cleanup function to component return { - url: URL.createObjectURL(file), + url: objectUrl, + cleanup: () => URL.revokeObjectURL(objectUrl), } - } - throw new Error('Fail to upload') }Committable suggestion was skipped due to low confidence.

Consider improving type safety and hook interface.
The current implementation could benefit from better type safety and a more structured hook interface.
Consider these improvements:
- headers = {} + headers: Record<string, string> = {} - beforeXhrUpload?: any + beforeXhrUpload?: (xhr: XMLHttpRequest, options: UploadOptions) => boolean | void // In the upload method - if (options.beforeXhrUpload) { - options.beforeXhrUpload(xhr, options) + if (options.beforeXhrUpload && options.beforeXhrUpload(xhr, options) !== false) { + xhr.send(options.formData) } else { xhr.send(options.formData) }This change:
- Adds proper typing for headers
- Improves the beforeXhrUpload hook interface with proper types
- Allows the hook to control whether the upload should proceed

⚠️ Potential issueImprove error handling in the

uploadActionfunction, when an upload fails, the error is caught, but then it's re-thrown withthrow e. This causes the entirePromise.allto reject, and the error is logged in the.catchblock.

24-33: 建议添加无障碍支持组件实现基本合理，但建议添加以下改进：
- 为上传组件添加
aria-label属性- 考虑添加上传状态的屏幕阅读器提示
建议修改如下：
<Cell style={{ flexWrap: 'wrap' }}> <Uploader value={list} onChange={setList} upload={(file: File) => upload(file)} multiple maxFileSize={1024 * 50} onOversize={onOversize} + aria-label="文件上传" + role="button" /> </Cell>src/packages/uploader/demos/taro/demo3.tsx (1)
14-20: 建议优化sleep函数的实现sleep函数可以添加参数类型约束和默认值，以提高代码的健壮性。
- function sleep(time: number) { + function sleep(time: number = 1000): Promise<void> { return new Promise<void>((resolve) => { setTimeout(() => { resolve() }, time) }) }src/packages/uploader/demos/taro/demo5.tsx (1)
6-14: 建议移除调试代码代码中的
console.log语句应该在生产环境中移除。建议应用以下修改：
const beforeUpload = async (files: File[]) => { const allowedTypes = ['image/png'] const filteredFiles = Array.from(files).filter((file) => allowedTypes.includes(file.type) ) - console.log(filteredFiles) return filteredFiles }src/packages/uploader/demo.taro.tsx (1)
19-21: 建议优化翻译文案的具体性翻译文案有以下几点可以改进：
- "限制上传数量" 建议添加默认限制数量，使用户更清晰了解限制
- "自定义上传前的处理" 可以更具体说明可以处理什么，比如文件大小、类型等
建议修改如下：
- limitedQuantity: '限制上传数量', + limitedQuantity: '限制上传数量（默认最多5个）', - beforeUpload: '自定义上传前的处理', + beforeUpload: '上传前自定义处理（大小、类型等）',Also applies to: 30-32, 41-42
src/packages/uploader/demos/taro/demo9.tsx (1)
7-40: 建议改进示例数据的真实性当前的示例数据有以下可以改进的地方：
- 文件名可以更贴近真实场景（如："产品图片.jpg"，"用户头像.png"）
- URL 地址都使用了相同的图片
- 建议展示更多样的文件类型（如：PDF、DOC等）
src/packages/uploader/uploader.taro.tsx (4)
82-87: 重构：上传处理机制的重大改进通过将HTTP上传逻辑从组件中分离出来，新的
upload方法提供了更灵活的上传实现方式。这种设计允许开发者：
- 自定义上传逻辑
- 更好地处理不同平台的上传需求
- 实现更复杂的上传场景（如分片上传）
建议在文档中提供一些常见上传实现的示例代码，特别是针对不同平台（H5、小程序等）的实现方案。
166-166: 优化：引入上传队列管理机制新增的上传队列管理提供了更好的上传控制：
- 支持手动触发上传
- 提供队列清理机制
- 实现了自动上传和手动上传的分离
建议添加以下功能增强：
- 上传队列状态变化的回调
- 队列暂停/恢复的控制方法
- 上传进度的批量监控
Also applies to: 171-172, 313-317
Line range hint
279-311: 注意：文件处理逻辑需要优化当前实现存在以下问题：
idCountRef计数器可能在组件重新挂载时重置- 文件类型检测依赖文件扩展名，可能不够准确
- 状态更新可能存在竞态条件
建议进行如下修改：
- const idCountRef = useRef(0) + const idCountRef = useRef(Date.now()) const readFile = async <T extends TFileType>(files: T[]) => { + const currentFileList = [...fileListRef.current] const tasks = files.map((file) => { // ... existing code ... }) - fileListRef.current = [...fileListRef.current, info] - setFileList(fileListRef.current) + const newFileList = [...currentFileList, info] + fileListRef.current = newFileList + setFileList(newFileList)

392-431: 建议：改进上传组件的可访问性和用户体验上传按钮和预览区域的实现需要考虑以下几点：
- 缺少键盘访问支持
- 缺少适当的 ARIA 属性
- 上传状态的视觉反馈不够明显
建议进行如下改进：
<View className={`nut-uploader-upload ${previewType} ${ disabled ? 'nut-uploader-upload-disabled' : '' }`} + role="button" + tabIndex={disabled ? -1 : 0} + aria-label={locale.uploader.uploadText} > <View className="nut-uploader-icon"> {uploadIcon} - <span className="nut-uploader-icon-tip">{uploadLabel}</span> + <span className="nut-uploader-icon-tip" aria-hidden="true"> + {uploadLabel} + </span> </View> <Button className="nut-uploader-input" onClick={_chooseImage} + aria-hidden="true" /> </View>

onOverCount回调，优化了文件数量限制的处理- 新增
onUploadQueueChange回调，方便跟踪上传队列状态
244-282: 🛠️ Refactor suggestion建议增强上传过程的错误处理和状态管理
当前实现可以进一步优化：
- 添加重试机制，提高上传可靠性
- 增加上传进度回调
- 完善错误信息展示，包含具体错误信息而不是通用错误提示
建议参考如下改进：
const uploadAction = async (tasks: FileItem[]) => { const taskIds = tasks.map((task) => task.uid) const list: FileItem[] = fileListRef.current.map((file: FileItem) => { if (taskIds.includes(file.uid)) { return { ...file, status: 'uploading', message: locale.uploader.uploading, } } return file }) setFileList(list) await Promise.all( tasks.map(async (currentTask, index) => { + let retryCount = 0 + const maxRetries = 3 + while (retryCount < maxRetries) { try { - const result = await upload(currentTask.file as File) + const result = await upload(currentTask.file as File).catch((e) => { + throw new Error(`上传失败: ${e.message}`) + }) const list = fileListRef.current.map((item) => { if (item.uid === currentTask.uid) { item.status = 'success' item.message = locale.uploader.success item.url = result.url } return item }) setFileList(list) + break } catch (e) { + retryCount++ + if (retryCount === maxRetries) { const list = fileListRef.current.map((item) => { if (item.uid === currentTask.uid) { item.status = 'error' - item.message = locale.uploader.error + item.message = e.message || locale.uploader.error } return item }) setFileList(list) + throw e } + await new Promise(resolve => setTimeout(resolve, 1000 * retryCount)) } + } }) - ).catch((errs) => console.error(errs)) + ).catch((errs) => { + console.error('上传失败:', errs) + props.onError?.(errs) + }) }Likely invalid or redundant comment.

const uploaderStyle = { - marginInlineEnd: '10px', - marginBottom: '10px', + marginInlineEnd: 'var(--nutui-margin-2)', + marginBottom: 'var(--nutui-margin-2)', }
31-33: 建议完善错误处理示例当前的失败处理过于简单，建议展示更实际的错误场景。
建议修改为：
async function uploadFail(file: File): Promise<FileItem> { await sleep(2000) - throw new Error('Fail to upload') + throw new Error('上传失败：网络连接超时，请重试') }
37-50: 建议增加更多的用户反馈上传组件的交互体验可以进一步优化，建议添加更多的用户反馈机制。
建议添加以下属性：
<Uploader uploadLabel="商品主图" value={list} onChange={setList} upload={(file: File) => upload(file)} style={uploaderStyle} + maxCount={5} + onDelete={(file) => console.log('删除文件', file)} + onProgress={(event) => console.log('上传进度', event)} />src/packages/uploader/demos/taro/demo1.tsx (3)
1-4: 建议优化导入语句的组织结构建议按照以下顺序组织导入语句：
- React 相关
- 第三方库组件
- 图标组件
- 本地类型定义
import React, { useState } from 'react' -import { Uploader, Cell } from '@nutui/nutui-react-taro' -import { Dongdong } from '@nutui/icons-react-taro' -import { FileItem } from '../../file-item' +import { Cell, Uploader } from '@nutui/nutui-react-taro' +import { Dongdong } from '@nutui/icons-react-taro' + +import { FileItem } from '../../file-item'
10-15: 建议改进初始状态的类型定义当前的状态初始化可以更严谨：
- 建议为初始文件项添加更多必要的属性（如 status, type 等）
- 考虑使用常量定义初始状态
-const [list, setList] = useState<FileItem[]>([ - { - url: demoUrl, - uid: 133, - }, -]) +const INITIAL_FILE: FileItem = { + url: demoUrl, + uid: 133, + status: 'success', + type: 'image', + name: 'demo-image.gif' +} +const [list, setList] = useState<FileItem[]>([INITIAL_FILE])
37-52: 建议优化组件结构和样式处理当前实现存在以下可以改进的地方：
- 样式定义应该抽离到单独的样式文件
- 缺少无障碍访问属性
- 上传组件的属性可以更好地组织
+// 抽离到 styles.ts +const styles = { + cell: { + flexWrap: 'wrap' as const, + }, + uploader: { + marginRight: '10px', + marginBottom: '10px', + }, +} -<Cell style={{ flexWrap: 'wrap' }}> +<Cell style={styles.cell}> <Uploader uploadLabel="商品主图" + accept="image/*" + aria-label="上传商品主图" value={list} onChange={setList} upload={(file: File) => upload(file)} - style={uploaderStyle} + style={styles.uploader} />src/packages/uploader/demos/h5/demo2.tsx (1)
7-47: 建议提取模拟数据到单独的常量文件中当前的模拟数据直接定义在组件中，并且包含重复的URL。建议进行以下优化：
- 将模拟数据提取到单独的常量文件中
- 将重复的URL定义为常量
- 考虑使用工厂函数来创建不同状态的文件项
建议修改如下：
+ // src/packages/uploader/demos/h5/mock.ts + const DEMO_IMAGE_URL = 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif' + + export const createFileItem = ( + uid: number, + status: string, + name?: string, + message?: string, + icon?: React.ReactNode + ): FileItem => ({ + uid, + name, + url: DEMO_IMAGE_URL, + status, + message, + ...(status === 'error' && icon && { failIcon: icon }), + ...(status === 'uploading' && icon && { loadingIcon: icon }), + }) + + export const mockFileList: FileItem[] = [ + createFileItem(111, 'success', '文件文件文件文件1文件文件文件文件1文件文件文件文件1.png', '上传成功'), + // ... 其他文件项 + ]src/packages/uploader/demos/taro/demo2.tsx (2)
7-47: 建议改进示例数据的真实性虽然示例数据展示了不同的上传状态，但有以下几点可以改进：
- 所有图片URL都相同，建议使用不同的示例图片
- 部分文件项缺少name属性，这可能无法很好地反映实际使用场景
- 建议添加不同类型的文件（如PDF、DOC等）来展示多样性
建议参考以下示例结构：
{ uid: 333, + name: '报告.pdf', - url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', + url: 'https://example.com/path/to/different/file.pdf', status: 'uploading', }
48-49: 建议增强删除事件的演示效果当前的删除事件处理仅打印日志，建议添加更多交互效果来展示组件的实际使用场景。
建议改进为：
const onDelete = (file: FileItem, fileList: FileItem[]) => { - console.log('delete事件触发', file, fileList) + console.log('文件删除事件触发：', { + 删除的文件: { + 名称: file.name, + 状态: file.status, + URL: file.url + }, + 剩余文件数量: fileList.length + }) }src/packages/uploader/preview.taro.tsx (2)
23-23: 状态处理逻辑的改进状态处理的改变使代码更加清晰，但建议进一步改进：
- 建议将状态值定义为常量枚举
- 可以将状态相关的渲染逻辑抽取为独立函数
建议添加以下类型定义：
export enum UploadStatus { READY = 'ready', SUCCESS = 'success', ERROR = 'error' }Also applies to: 55-71
116-124: 列表视图样式优化建议为文件名添加状态类名是个好的改进，但有以下建议：
- 考虑添加 CSS 类型定义
- 建议在组件文档中说明各状态对应的样式效果
需要我帮助更新组件文档吗？

1-4: 🛠️ Refactor suggestion
需要从 @nutui/nutui-react 包中导入类型定义
根据之前的评论，FileItem 类型应该从 @nutui/nutui-react 包中导入，而不是从相对路径导入。这样可以确保类型定义的一致性和可维护性。
建议修改为：
import React, { useState } from 'react'
-import { Uploader, Cell } from '@nutui/nutui-react'
+import { Uploader, Cell, FileItem } from '@nutui/nutui-react'
import { Dongdong } from '@nutui/icons-react'
-import { FileItem } from '../../file-item'src/packages/uploader/demos/h5/demo2.tsx (1)
1-6: 导入声明和组件结构清晰明确！
组件命名与文件名保持一致，导入声明组织合理。
src/packages/uploader/demos/taro/demo2.tsx (1)
2-4: 导入语句结构清晰且合理！
所有必要的组件和图标都已正确导入，符合组件的使用需求。
src/packages/uploader/preview.taro.tsx (3)
34-41: 优化的属性解构模式
使用解构赋值并提供默认值是一个很好的改进，它能：
- 提高代码可读性
- 确保属性缺失时的安全性
- 减少重复的属性访问
77-84: 注意图片展示模式的变更
将图片模式从 aspectFit 更改为 aspectFill 可能会影响现有的图片展示效果：
aspectFill会裁剪图片以填充容器- 这可能导致图片部分内容被裁切
另外，成功状态下显示文件名的新增功能很好地提升了用户体验。
建议验证这个改动对现有上传组件的影响：
#!/bin/bash
# 检查其他使用 Image 组件的地方
rg "mode=['\"]aspectFit['\"]" Also applies to: 107-109
8-10: 导入路径的改进
从 @tarojs/components 切换到自定义的 @/packages/image/image.taro 组件可能会提供更好的跨平台兼容性和自定义功能。
验证新的图片组件实现：
✅ Verification successful
Let me gather more information about the Image component implementation.
从 @tarojs/components 切换到自定义 Image 组件是合理的改进
从代码实现来看，自定义的 @/packages/image/image.taro 组件是对原生 Taro Image 组件的增强封装，提供了以下优势：
- 统一的错误处理和加载状态展示
- 更好的跨平台样式处理（RN、Web、小程序）
- 简化的尺寸和圆角配置

6-26: 建议添加类型注释并优化类型定义建议对
FileItem类型做以下改进：
- 添加 JSDoc 注释说明每个属性的用途
- 考虑将部分关键属性设为必填，如
uid和statustype属性的字符串联合类型可以更严格，建议列举所有可能的值示例改进：
+ /** + * 文件项的类型定义 + */ type FileItem = { + /** 文件状态 */ - status?: FileItemStatus + status: FileItemStatus + /** 状态信息 */ message?: string + /** 唯一标识符 */ - uid?: string | number + uid: string | number + /** 文件名称 */ name?: string + /** 文件URL */ url?: string + /** 文件类型 */ - type?: 'image' | 'list' | string + type?: 'image' | 'video' | 'audio' | 'document' | 'list' // ... 其他属性保持不变 }
28-28: 建议为状态类型添加注释为了提高代码可维护性，建议添加类型注释说明每个状态的含义。
+ /** + * 文件项状态 + * @description + * - ready: 准备上传 + * - uploading: 上传中 + * - success: 上传成功 + * - error: 上传失败 + */ type FileItemStatus = 'ready' | 'uploading' | 'success' | 'error'
1-1: 建议添加模块级文档作为 Uploader 3.0 重构的一部分，建议在文件顶部添加完整的模块文档，包括：
- 模块的整体功能说明
- 导出内容的概述
- 版本变更说明
+ /** + * @file Uploader 组件类型定义 + * @description Uploader 3.0 版本的核心类型定义，包含文件项、状态等类型 + * @version 3.0.0 + */ import { ReactNode } from 'react'Also applies to: 32-32
src/packages/uploader/demos/h5/demo4.tsx (1)
6-21: 建议优化工具函数和错误处理代码功能实现正确，但有以下优化建议：
sleep工具函数建议移至公共工具文件upload函数需要添加错误处理- 建议将文件大小限制提取为常量
建议按如下方式重构：
+const MAX_FILE_SIZE = 1024 * 50 +const FILE_SIZE_ERROR_MESSAGE = '文件大小不能超过 50kb' const onOversize = (files: File[]) => { - console.log('oversize 触发 文件大小不能超过 50kb', files) + console.log(`oversize 触发 ${FILE_SIZE_ERROR_MESSAGE}`, files) } async function upload(file: File) { + try { await sleep(2000) return { url: URL.createObjectURL(file), } + } catch (error) { + console.error('文件上传失败:', error) + throw error + } }src/packages/uploader/demos/taro/demo7.tsx (3)
5-11: 建议优化文件名称当前文件名
文件文件文件文件1文件文件文件文件1文件文件文件文件1.png存在重复文本，建议简化为更清晰的示例名称。建议修改如下：
- name: '文件文件文件文件1文件文件文件文件1文件文件文件文件1.png', + name: '示例文件1.png',
15-23: 建议区分两个上传组件的默认值两个上传组件共用相同的
defaultFileList，这可能会导致用户困惑。建议为每个上传组件设置不同的默认值，以更好地展示其独特性。建议修改如下：
+const defaultFileList1 = [{ + name: '示例文件1.png', + url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', + message: '上传成功', +}] + +const defaultFileList2 = [{ + name: '示例文件2.png', + url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', + message: '上传成功', +}] <Uploader - defaultValue={defaultFileList} + defaultValue={defaultFileList1} ... /> <Uploader - defaultValue={defaultFileList} + defaultValue={defaultFileList2} ... />Also applies to: 24-29
14-30: 建议优化组件结构当前的布局结构可以通过添加适当的标题或描述来提高可读性和可用性。
建议修改如下：
<Cell style={{ flexWrap: 'wrap' }}> + <Cell.Group title="自定义上传图标展示"> <Uploader defaultValue={defaultFileList} uploadIcon={<Dongdong />} deleteIcon={<Star />} style={{ marginInlineEnd: '10px', }} maxCount={1} /> <Uploader defaultValue={defaultFileList} uploadIcon={<Star />} deleteIcon={<Dongdong />} maxCount={1} /> + </Cell.Group> </Cell>src/packages/uploader/demos/h5/demo3.tsx (2)
6-9: 建议改进样式对象的命名和类型定义建议进行以下优化：
- 为样式对象添加类型定义
- 考虑将样式对象提升到组件外部以提高性能
+type UploaderStyleType = { + marginInlineEnd: string + marginBottom: string +} + +const uploaderStyle: UploaderStyleType = { marginInlineEnd: '10px', marginBottom: '10px', } + const Demo3 = () => {
10-16: sleep 函数实现可以更简洁当前的 Promise 实现可以简化。
-function sleep(time: number) { - return new Promise<void>((resolve) => { - setTimeout(() => { - resolve() - }, time) - }) -} +const sleep = (time: number) => new Promise<void>((resolve) => setTimeout(resolve, time))src/packages/uploader/demos/h5/demo5.tsx (1)
6-12: 建议优化文件类型过滤的实现当前实现可以考虑以下改进：
- 将允许的文件类型作为配置项
- 添加文件被过滤时的用户提示
建议参考以下实现：
- const beforeUpload = async (files: File[]) => { - const allowedTypes = ['image/png'] - const filteredFiles = Array.from(files).filter((file) => - allowedTypes.includes(file.type) - ) - return filteredFiles - } + const allowedTypes = ['image/png'] + const beforeUpload = async (files: File[]) => { + const filteredFiles = Array.from(files).filter((file) => { + const isAllowed = allowedTypes.includes(file.type) + if (!isAllowed) { + console.warn(`文件类型不支持: ${file.name}`) + } + return isAllowed + }) + return filteredFiles + }src/packages/uploader/demos/taro/demo3.tsx (1)
9-24: 建议优化上传模拟函数的实现当前的实现有以下几点可以改进：
- upload 函数缺少错误处理
- 固定的演示URL可能导致测试场景单一
- sleep 函数可以考虑提取到公共工具中复用
建议按照以下方式优化：
async function upload(file: File) { + try { await sleep(2000) return { url: demoUrl, + status: 'success', + message: '上传成功' } + } catch (error) { + return { + status: 'error', + message: '上传失败' + } + } }src/packages/uploader/demos/taro/demo4.tsx (3)
1-2: 建议优化类型导入建议将 FileItem 类型从其他类型中分离出来单独导入，以提高代码的可维护性：
-import { Uploader, Cell, FileItem } from '@nutui/nutui-react-taro' +import type { FileItem } from '@nutui/nutui-react-taro/dist/types' +import { Uploader, Cell } from '@nutui/nutui-react-taro'
8-8: 建议使用类型推导优化状态声明当前的状态声明可以利用 TypeScript 的类型推导功能来简化：
-const [list, setList] = useState<FileItem[]>([]) +const [list, setList] = useState(() => [] as FileItem[])这样可以获得更好的性能，因为初始状态使用函数形式可以避免在每次渲染时都创建新数组。
28-36: 建议增加无障碍访问支持为了提高组件的可访问性，建议添加相关的 ARIA 属性：
<Cell style={{ flexWrap: 'wrap' }}> <Uploader value={list} onChange={setList} upload={(file: File) => upload(file)} maxFileSize={1024 * 50} onOversize={onOversize} + aria-label="文件上传" + role="button" + data-testid="demo4-uploader" /> </Cell>src/packages/uploader/demos/taro/demo5.tsx (2)
13-24: 建议改进上传模拟实现的灵活性当前实现存在以下可以改进的地方：
- 延迟时间被硬编码为2秒
- 返回URL被硬编码在函数中
- 缺少错误处理机制
建议按照以下方式重构：
+ const DEMO_IMAGE_URL = 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif' + const UPLOAD_DELAY = 2000 + function sleep(time: number) { return new Promise<void>((resolve) => { setTimeout(() => { resolve() }, time) }) } async function upload(file: File) { + try { - await sleep(2000) + await sleep(UPLOAD_DELAY) return { - url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', + url: DEMO_IMAGE_URL, } + } catch (error) { + console.error('上传失败:', error) + throw error + } }
27-34: 建议增加无障碍访问支持上传组件应该添加适当的 ARIA 属性以提升可访问性。
建议修改如下：
<Cell style={{ flexWrap: 'wrap' }}> <Uploader value={list} onChange={setList} beforeUpload={beforeUpload} upload={(file: File) => upload(file)} + aria-label="图片上传" + role="button" /> </Cell>src/packages/uploader/demos/h5/demo1.tsx (1)
6-11: 建议优化初始状态的设置当前的初始状态使用了硬编码的URL和uid，建议：
- 使用更有意义的示例图片
- 添加更多的文件属性来展示组件的完整功能
const [list, setList] = useState<FileItem[]>([ { - url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', - uid: 133, + url: '示例图片URL', + uid: 1, + status: 'success', + type: 'image', + name: '示例图片.jpg' }, ])src/packages/uploader/demos/taro/demo1.tsx (2)
9-14: 建议完善初始状态的 FileItem 结构初始状态的 FileItem 对象缺少完整的属性定义，建议与上传函数返回的对象保持一致。
const [list, setList] = useState<FileItem[]>([ { url: demoUrl, uid: 133, + status: 'success', + type: 'image/gif', + name: 'demo-image.gif', }, ])
45-50: 建议优化组件结构当前实现中有多个 Uploader 组件实例，建议：
- 将样式抽取到独立的样式文件
- 考虑将不同场景的 Uploader 封装为独立的演示组件
- 添加适当的注释说明每个实例的用途
+// 成功上传示例 <Uploader style={uploaderStyle} upload={(file: File) => upload(file)} /> +// 上传失败示例 <Uploader uploadIcon={<Dongdong />} upload={(file: File) => uploadFail(file)} style={uploaderStyle} />src/packages/uploader/demos/h5/demo2.tsx (2)
5-5: 建议添加组件重命名的注释说明组件从
Demo1重命名为Demo2，建议添加注释说明重命名的原因，以便其他开发者理解。+// 重命名自 Demo1，用于展示带有默认值的上传组件示例 const Demo2 = () => {
51-56: 建议添加属性类型说明为了提高代码可维护性，建议为 Uploader 组件的属性添加类型说明注释。
<Uploader + // 上传文件的默认列表 defaultValue={defaultList} + // 删除文件时的回调函数 onDelete={onDelete} + // 自定义上传图标 uploadIcon={<Dongdong />} + // 最大上传文件数量 maxCount={6} />src/packages/uploader/demos/h5/demo10.tsx (1)
6-39: 建议改进初始状态数据的处理方式
- 建议将硬编码的图片URL替换为配置常量或环境变量
- 文件名过长可能会导致UI显示问题，建议添加文件名长度限制
建议按照以下方式重构：
+ const MAX_FILENAME_LENGTH = 20; + const DEFAULT_PREVIEW_IMAGE = process.env.DEFAULT_PREVIEW_IMAGE || 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif'; const [list, setList] = useState<FileItem[]>([ { - name: '文件文件文件文件1文件文件文件文件1文件文件文件文件1.png', + name: '示例文件1.png', - url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', + url: DEFAULT_PREVIEW_IMAGE, status: 'success', message: '上传成功', }, // ... 其他项目类似更新 ])src/packages/uploader/demos/taro/demo9.tsx (1)
6-39: 建议改进初始状态的模拟数据当前的模拟数据存在以下可以改进的地方：
- 所有文件使用了相同的图片URL
- 文件名称可以更贴近实际场景
- 状态消息建议使用国际化配置
建议按照以下方式优化：
const [list, setList] = useState<FileItem[]>([ { - name: '文件文件文件文件1文件文件文件文件1文件文件文件文件1.png', + name: 'product-image-01.png', url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', status: 'success', - message: '上传成功', + message: t('uploadSuccess'), }, // ... 其他项目类似更新 ])src/packages/uploader/uploader.tsx (2)
Line range hint
281-334: 渲染逻辑建议优化渲染逻辑结构清晰，但建议进行以下优化：
- 使用
useMemo优化渲染性能- 提取公共的 input 组件减少代码重复
建议重构如下：
+const UploadInput = React.memo(({ + maxCount, + fileList, + ...props +}) => { + if (Number(maxCount) <= fileList.length) return null + return ( + <input + className="nut-uploader-input" + type="file" + {...props} + /> + ) +}) -const renderImageUploader = () => { +const renderImageUploader = React.useMemo(() => { // ... existing code -} +}, [maxCount, fileList, disabled, uploadIcon, uploadLabel])🧰 Tools

83-85: 建议优化 upload 属性的类型定义当前的类型定义中，upload 方法接受的参数类型过于宽泛（使用了 any）。建议根据不同环境定义更精确的联合类型，以提供更好的类型安全性。
- upload: ( - files: Taro.chooseImage.ImageFile | Taro.chooseMedia.ChooseMedia | any - ) => Promise<FileItem> + upload: ( + files: Taro.chooseImage.ImageFile | Taro.chooseMedia.ChooseMedia | File + ) => Promise<FileItem>

390-426: 建议优化渲染逻辑的组织结构当前渲染逻辑存在以下可优化点：
- 渲染逻辑分散在多个函数中
- 条件判断逻辑复杂
- 样式类名拼接方式不够优雅
建议：
- 使用组件拆分替代渲染函数
- 使用策略模式处理不同的预览类型
- 使用 classnames 统一处理类名
- const renderListUploader = () => { - return (...) - } - const renderImageUploader = () => { - return (...) - } + const ListUploader: React.FC = () => { + return (...) + } + const ImageUploader: React.FC = () => { + return (...) + }src/packages/uploader/demos/taro/demo2.tsx (3)
9-9: 文件名过长可能影响界面展示在第9行，uid为111的文件名过长，可能会导致在界面上显示不完整，影响用户体验。建议适当缩短文件名或在界面上处理超长文件名的显示，确保界面美观。
22-25: 为上传中的文件（uid: 333）添加提示信息和加载动画当前uid为333的
FileItem缺少message和loadingIcon属性，用户可能无法了解上传进度。建议添加提示信息和加载动画以提升用户体验。应用以下修改：
{ uid: 333, url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', status: 'uploading', + message: '上传中...', + loadingIcon: <Loading className="nut-icon-Loading" color="#fff" />, },
34-38: 为上传失败的文件（uid: 555）添加失败图标uid为555的
FileItem在上传失败时没有提供failIcon，这可能导致用户无法直观地识别失败状态。建议与uid为444的文件保持一致，添加failIcon以统一用户体验。应用以下修改：
{ uid: 555, url: 'https://m.360buyimg.com/babel/jfs/t1/164410/22/25162/93384/616eac6cE6c711350/0cac53c1b82e1b05.gif', status: 'error', message: '上传失败', + failIcon: <Star style={{ color: 'white' }} />, },

30-30: 建议明确 FileType 类型的使用场景
FileType 是一个通用的键值映射类型，但其用途和使用场景不够明确。建议：
- 添加详细的类型注释说明使用场景
- 考虑使用更具描述性的类型名称
- 如果可能，提供使用示例
让我们检查一下这个类型在代码库中的使用情况：
src/packages/uploader/demos/h5/demo4.tsx (1)
1-5: 代码结构清晰，状态管理合理！
使用 useState 管理文件列表状态，符合 React Hooks 的最佳实践。导入声明简洁明确。
src/packages/uploader/demos/taro/demo7.tsx (2)
1-3: 导入声明看起来不错！
导入语句组织得当，包含了所有必要的组件和图标。
14-14: 建议将样式迁移到样式文件中
当前组件使用内联样式定义布局，这降低了代码的可维护性。建议将样式迁移到独立的样式文件中。
Also applies to: 19-21
src/packages/uploader/demos/h5/demo3.tsx (1)
1-5: 导入声明和状态管理的实现看起来不错！
使用 useState 管理文件列表状态是一个很好的做法，这样可以更好地控制上传组件的行为。
src/packages/uploader/demos/h5/demo5.tsx (1)
1-5: 代码结构清晰，类型定义完整！
使用 TypeScript 类型定义确保了类型安全，FileItem[] 的状态管理实现规范。
src/packages/uploader/demos/taro/demo3.tsx (2)
1-8: 导入声明和状态管理的实现看起来不错！
代码结构清晰，使用了 React 的 useState 进行状态管理，符合最佳实践。
1-38: 验证组件在不同场景下的表现
需要验证以下场景：
- 文件类型限制
- 并发上传限制
- 大文件上传
- 网络异常处理
✅ Verification successful
已验证上传组件的各项功能实现
通过分析代码库，发现上传组件已经完整实现了所有关注的场景:
-
文件类型限制:
- Demo5 中通过
beforeUpload实现了文件类型过滤 - 组件支持
accept属性限制文件类型
- Demo5 中通过
-
并发上传限制:
- 组件支持
multiple属性控制是否允许多文件上传 maxCount属性限制最大上传数量autoUpload属性控制是否自动上传,可以手动控制上传时机
- 组件支持
-
大文件上传:
maxFileSize属性限制文件大小onOversize回调处理超限文件
-
网络异常处理:
- 上传失败时自动设置 error 状态
- 支持自定义失败图标和提示信息
- Demo1/Demo10 展示了上传失败的处理方式
所有这些功能都有完整的示例代码和实现,无需额外验证。

1-5: 代码结构清晰，使用了适当的类型定义！
组件的基础架构符合 React 最佳实践，使用了 TypeScript 类型定义确保类型安全。
6-12: 文件类型过滤实现仍需改进
之前的审查意见仍然有效。
src/packages/uploader/demos/h5/demo1.tsx (1)
1-2: 类型导入需要优化
建议将类型从专门的类型定义文件中导入，以保持一致性：
import React, { useState } from 'react'
-import { Uploader, Cell, FileItem } from '@nutui/nutui-react'
+import { Uploader, Cell } from '@nutui/nutui-react'
+import type { FileItem } from '@nutui/nutui-react/dist/types'src/packages/uploader/demos/taro/demo1.tsx (1)
38-44: 建议添加状态管理相关的测试用例
需要为组件添加以下测试场景：
- 文件列表的初始状态验证
- setList 回调函数的调用验证
- 上传成功和失败的状态变化验证
src/packages/uploader/demos/h5/demo2.tsx (1)
47-49: 请参考之前的代码审查建议
之前的代码审查中已经指出了 onDelete 处理器的改进建议，这些建议仍然有效。
src/packages/uploader/demos/h5/demo10.tsx (1)
1-3: 导入声明看起来不错！
代码使用了命名导入，结构清晰，包含了所有必要的依赖项。
src/packages/uploader/demos/taro/demo9.tsx (1)
1-3: 导入声明看起来不错！
导入的依赖项都是必要的，并且符合组件的功能需求。
src/packages/uploader/uploader.tsx (1)
27-27: 请确认新的上传函数接口设计
upload 函数的设计简化了组件接口，提供了更大的灵活性。但是默认的 maxCount 设置为 Number.MAX_VALUE 可能会带来潜在的内存问题。建议设置一个更合理的默认值，比如 10 或 20。
Also applies to: 55-55

242-280:
建议增强错误处理和重试机制
当前上传实现存在以下问题：
- 错误处理过于简单，仅打印错误
- 缺少重试机制
- 没有上传进度回调
建议添加以下功能：
- 完善的错误处理回调
- 自动重试机制
- 上传进度通知
- ).catch((errs) => console.error(errs))
+ ).catch((errs) => {
+ const retryCount = 3;
+ const retryDelay = 1000;
+
+ const retry = async (task: FileItem, attempt: number) => {
+ try {
+ const result = await upload(task.file as File);
+ updateFileStatus(task.uid, 'success', result.url);
+ } catch (error) {
+ if (attempt < retryCount) {
+ setTimeout(() => retry(task, attempt + 1), retryDelay);
+ } else {
+ updateFileStatus(task.uid, 'error', locale.uploader.error);

47-48: 删除事件处理逻辑完善
onDelete函数正确地处理了文件删除事件，并输出了相关信息，逻辑清晰，符合预期。
51-56: Uploader组件配置合理
Uploader组件的配置满足示例需求，使用了自定义的uploadIcon，并设置了合适的maxCount，组件显示效果良好。

282-349: UI渲染逻辑可以进一步优化当前实现已经将图片上传器和列表上传器的渲染逻辑分离，这是个很好的改进。不过还可以进一步优化：
- 建议将通用的input部分抽取为独立组件：
interface UploaderInputProps { capture: boolean | 'user' | 'environment' name: string accept: string disabled: boolean multiple: boolean onChange: (event: React.ChangeEvent<HTMLInputElement>) => void } const UploaderInput: React.FC<UploaderInputProps> = (props) => ( <input className="nut-uploader-input" type="file" {...props} /> )
- 使用组合模式重构渲染逻辑：
- const renderImageUploader = () => { + const ImageUploader: React.FC<{show: boolean}> = ({show}) => { return ( - shouldShow && ( + show && ( <div className={classNames('nut-uploader-upload', previewType)}> {/* ... */} - <input {...inputProps} /> + <UploaderInput {...inputProps} /> </div> ) ) }src/packages/uploader/uploader.taro.tsx (3)
81-91: 接口设计改进建议新增的属性改进了上传控制，但建议进一步完善类型定义：
upload方法返回的FileItem应该有更明确的类型约束beforeUpload的返回值类型File[]可能与 Taro 环境不完全匹配建议添加以下类型定义：
interface UploadResult extends FileItem { url: string; status: 'success' | 'error'; message?: string; } upload: (file: File | Taro.chooseImage.ImageFile | Taro.chooseMedia.ChooseMedia) => Promise<UploadResult>
Line range hint
284-321: 建议增强文件处理逻辑文件处理逻辑可以进一步优化：
- 文件类型检测可以更严格
- 缺少文件大小的预检查
- 文件名处理需要考虑更多场景
建议进行以下优化：
const readFile = async <T extends TFileType>(files: T[]) => { + // 预检查文件 + const validateFile = (file: T) => { + if (!file) return false + // 检查文件大小 + if (file.size > maxFileSize) return false + // 检查文件类型 + const allowedTypes = accept.split(',').map(type => type.trim()) + if (allowedTypes[0] !== '*' && !allowedTypes.includes(file.type)) return false + return true + } + const tasks = files.map((file) => { + if (!validateFile(file)) { + throw new Error(`文件 ${file.name} 验证失败`) + }
391-425: 建议优化无障碍访问支持上传组件的UI渲染需要增强无障碍支持：
- 缺少适当的 ARIA 属性
- 键盘导航支持不足
- 上传状态提示可以更友好
建议添加以下优化：
const renderListUploader = () => { return ( previewType === 'list' && ( - <View className="nut-uploader-slot"> + <View + className="nut-uploader-slot" + role="region" + aria-label={locale.uploader.uploadArea} + > <> - <Button size="small" type="primary"> + <Button + size="small" + type="primary" + aria-label={locale.uploader.selectFile} + >
