# 文件上传与任务状态管理优化实施计划
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** 优化文件上传用户体验(进度条、拖拽、验证)和任务状态管理(重试、智能轮询、通知),提升系统易用性和反馈机制
**Architecture:** 在现有Vue 3组件架构上进行增量式增强新增5个UI组件和2个工具函数修改3个现有文件保持向后兼容性
**Tech Stack:** Vue 3 Composition API, Axios, Ant Design Vue Icons, HTML5 Drag & Drop API, CSS3 Animations

## Task 1: 创建文件验证工具函数
**Files:**
- Create: `src/utils/fileValidator.js`
- Test: 手动测试(浏览器控制台)
**目标:** 实现前端文件验证逻辑,支持类型检查、大小限制、文件名合法性校验
- [ ] **Step 1: 编写 fileValidator.js 基础结构**
```javascript
/**
* 文件验证工具函数
* 用于在上传前对文件进行前端验证,减少无效请求
*/
// 支持的文件扩展名白名单
const ALLOWED_EXTENSIONS = [
'.docx', '.pdf', '.txt', '.md',
'.xlsx', '.pptx', '.doc', '.xls', '.ppt'
]
// 最大文件大小50MB
const MAX_FILE_SIZE = 50 * 1024 * 1024
// 最大文件名长度
const MAX_FILENAME_LENGTH = 200
// 禁止的文件名字符
const INVALID_FILENAME_CHARS = /[\\/:*?"<>|]/
/**
* 验证单个文件
* @param {File} file - File对象
* @returns {{ valid: boolean, errors: string[] }}
*/
export function validateFile(file) {
const errors = []
// 1. 检查文件是否存在
if (!file) {
errors.push('未选择文件')
return { valid: false, errors }
}
// 2. 检查文件名长度
if (file.name.length > MAX_FILENAME_LENGTH) {
errors.push(`文件名过长 (${file.name.length}字符,限制${MAX_FILENAME_LENGTH}字符)`)
}
// 3. 检查文件名是否包含非法字符
if (INVALID_FILENAME_CHARS.test(file.name)) {
errors.push('文件名包含非法字符 (\\ / : * ? " < > |)')
}
// 4. 检查文件扩展名
const ext = getFileExtension(file.name)
if (!ALLOWED_EXTENSIONS.includes(ext.toLowerCase())) {
errors.push(`不支持的文件格式 (.${ext}),支持格式:${ALLOWED_EXTENSIONS.join(', ')}`)
}
// 5. 检查文件大小
if (file.size > MAX_FILE_SIZE) {
errors.push(`文件过大 (${formatFileSize(file.size)},限制${formatFileSize(MAX_FILE_SIZE)})`)
}
// 6. 检查文件大小是否为0空文件
if (file.size === 0) {
errors.push('文件为空0字节')
}
return {
valid: errors.length === 0,
errors,
ext,
size: file.size
}
}
/**
* 批量验证多个文件
* @param {File[]} files - File对象数组
* @returns {{ validFiles: File[], invalidFiles: { file: File, errors: string[] }[] }}
*/
export function validateFiles(files) {
const validFiles = []
const invalidFiles = []
files.forEach(file => {
const result = validateFile(file)
if (result.valid) {
validFiles.push(file)
} else {
invalidFiles.push({
file,
errors: result.errors
})
}
})
return { validFiles, invalidFiles }
}
/**
* 获取文件扩展名(含点号)
* @param {string} filename - 文件名
* @returns {string}
*/
function getFileExtension(filename) {
const lastDotIndex = filename.lastIndexOf('.')
if (lastDotIndex === -1) return ''
return filename.substring(lastDotIndex).toLowerCase()
}
/**
* 格式化文件大小为可读字符串
* @param {number} bytes - 字节数
* @returns {string}
*/
export function formatFileSize(bytes) {
if (!bytes || bytes === 0) return '0B'
const units = ['B', 'KB', 'MB', 'GB']
const i = Math.floor(Math.log(bytes) / Math.log(1024))
const size = parseFloat((bytes / Math.pow(1024, i)).toFixed(1))
return `${size}${units[i]}`
}
/**
* 根据扩展名获取文件类型标签
* @param {string} ext - 扩展名(含点号)
* @returns {string}
*/
export function getFileTypeLabel(ext) {
const typeMap = {
'.docx': 'Word文档',
'.doc': 'Word文档',
'.pdf': 'PDF文档',
'.xlsx': 'Excel表格',
'.xls': 'Excel表格',
'.pptx': 'PowerPoint演示',
'.ppt': 'PowerPoint演示',
'.txt': '文本文件',
'.md': 'Markdown文档'
}
return typeMap[ext.toLowerCase()] || '未知类型'
}
/**
* 根据扩展名获取对应的图标组件名
* @param {string} ext - 扩展名(含点号)
* @returns {string} Ant Design图标组件名
*/
export function getFileIconName(ext) {
const iconMap = {
'.docx': 'FileWordOutlined',
'.doc': 'FileWordOutlined',
'.pdf': 'FilePdfOutlined',
'.xlsx': 'FileExcelOutlined',
'.xls': 'FileExcelOutlined',
'.pptx': 'FilePptOutlined',
'.ppt': 'FilePptOutlined',
'.txt': 'FileTextOutlined',
'.md': 'FileTextOutlined'
}
return iconMap[ext.toLowerCase()] || 'FileOutlined'
}
export default {
validateFile,
validateFiles,
formatFileSize,
getFileTypeLabel,
getFileIconName,
ALLOWED_EXTENSIONS,
MAX_FILE_SIZE
}
```
- [ ] **Step 2: 测试验证函数**
在浏览器控制台执行:
```javascript
// 导入模块后测试
import { validateFile, validateFiles, formatFileSize } from './utils/fileValidator.js'
// 测试1: 有效文件
const validFile = new File(['test'], 'document.docx', { type: 'application/docx' })
console.log(validateFile(validFile))
// 预期: { valid: true, errors: [], ext: '.docx', size: 4 }
// 测试2: 无效扩展名
const invalidExt = new File(['test'], 'script.exe', {})
console.log(validateFile(invalidExt))
// 预期: { valid: false, errors: ["不支持的文件格式 (.exe)..."] }
// 测试3: 文件过大(模拟)
const largeFile = new File(new Array(60*1024*1024), 'large.docx', {})
console.log(validateFile(largeFile))
// 预期: { valid: false, errors: ["文件过大..."] }
// 测试4: 格式化文件大小
console.log(formatFileSize(1024 * 1024 * 2.3))
// 预期: "2.3MB"
```
- [ ] **Step 3: Commit**
```bash
git add src/utils/fileValidator.js
git commit -m "feat: add file validation utility with type/size/name checks"
```

```
- [ ] **Step 2: 测试拖拽功能**
在页面中使用:
```vue
<DropZone
@files-selected="handleUpload"
@error="handleError"
/>
```
测试场景:
1. 从桌面拖拽 .docx 文件到区域 → 触发 files-selected 事件
2. 拖拽 .exe 文件 → 触发 error 事件,显示错误信息
3. 点击区域 → 打开文件选择对话框
4. 同时拖拽多个文件 → 全部添加到预览列表
- [ ] **Step 3: Commit**
```bash
git add src/components/ui/DropZone.vue
git commit -m "feat: add DropZone component with drag-and-drop and validation"
```

## Task 4: 修改API层添加进度回调
**Files:**
- Modify: `src/api/file.js` (第67-73行)
**目标:** 为 uploadFile 方法添加 onUploadProgress 回调参数,支持实时进度监控
- [ ] **Step 1: 修改 uploadFile 方法签名和实现**
找到 `src/api/file.js` 第67-73行的 `uploadFile` 方法:
```javascript
// 当前代码:
uploadFile: (formData) => {
return apiClient.post('/file/upload', formData, {
headers: {
'Content-Type': 'multipart/form-data'
}
})
},
```
替换为:
```javascript
uploadFile: (formData, onProgress) => {
return apiClient.post('/file/upload', formData, {
headers: {
'Content-Type': 'multipart/form-data'
},
onUploadProgress: (progressEvent) => {
// 仅在有回调函数且存在total时才触发
if (typeof onProgress === 'function' && progressEvent.total) {
const percentCompleted = Math.round(
(progressEvent.loaded * 100) / progressEvent.total
)
onProgress({
loaded: progressEvent.loaded,
total: progressEvent.total,
percent: percentCompleted,
// 计算预估剩余时间(简单估算)
estimatedTimeRemaining: calculateRemainingTime(progressEvent)
})
}
}
})
},
```
- [ ] **Step 2: 添加辅助计算函数**
`api/file.js` 文件末尾第124行之后添加
```javascript
/**
* 简单估算剩余时间(基于最近速度)
* @param {ProgressEvent} progressEvent
* @returns {number|null} 预估剩余秒数无法估算时返回null
*/
function calculateRemainingTime(progressEvent) {
if (!progressEvent.total || progressEvent.total === 0) return null
const loaded = progressEvent.loaded
const total = progressEvent.total
const remaining = total - loaded
// 简单线性估算(实际应使用更复杂的算法)
// 这里假设速度恒定,返回秒数
if (remaining <= 0) return 0
// 由于无法获取精确时间戳这里返回null
// 实际应用中可以使用 performance.now() 记录时间差
return null
}
```
- [ ] **Step 3: 测试新接口**
```javascript
// 使用示例:
import { fileAPI } from './api/file.js'
const formData = new FormData()
formData.append('file', fileObject)
fileAPI.uploadFile(formData, (progress) => {
console.log(`上传进度: ${progress.percent}%`)
console.log(`已上传: ${(progress.loaded / 1024 / 1024).toFixed(1)}MB`)
// 更新UI进度条...
}).then(response => {
console.log('上传完成:', response.data)
}).catch(error => {
console.error('上传失败:', error)
})
```
- [ ] **Step 4: Commit**
```bash
git add src/api/file.js
git commit -m "feat: add upload progress callback to fileAPI.uploadFile method"
```

## Task 5: 集成增强功能到 FileSelector 组件
**Files:**
- Modify: `src/components/FileSelector.vue`
**目标:** 将拖拽上传、文件验证、进度条集成到现有的 FileSelector 组件中
- [ ] **Step 1: 导入新组件和工具函数**
`<script setup>` 部分顶部添加导入:
```javascript
import { ref, watch, onMounted } from 'vue'
import { message } from 'ant-design-vue'
import {
FileTextOutlined, SearchOutlined, DownOutlined,
CloseOutlined, LeftOutlined, RightOutlined,
DatabaseOutlined, UnorderedListOutlined, CopyOutlined,
InboxOutlined, FileSearchOutlined, LoadingOutlined,
CloudUploadOutlined, UploadOutlined, DeleteOutlined
} from '@ant-design/icons-vue'
// 新增导入:
import DropZone from './ui/DropZone.vue'
import ProgressBar from './ui/ProgressBar.vue'
import { formatFileSize, validateFile } from '../utils/fileValidator.js'
import { fileAPI } from '../../api/file.js'
```
- [ ] **Step 2: 添加响应式变量和方法**
在 script 中添加新的状态变量和方法:
```javascript
// ===== 新增:上传相关状态 =====
const uploadingFiles = ref([]) // 正在上传的文件列表
const uploadProgress = ref({}) // 进度映射 { fileId: { percent, status } }
/**
* 处理文件选择/拖拽
*/
async function handleFilesSelected(files) {
for (const file of files) {
await uploadSingleFile(file)
}
}
/**
* 上传单个文件
*/
async function uploadSingleFile(file) {
const validation = validateFile(file)
if (!validation.valid) {
message.error(`${file.name}: ${validation.errors.join('; ')}`)
return
}
const fileId = Date.now() + '_' + Math.random().toString(36).substr(2, 9)
// 初始化进度状态
uploadProgress.value[fileId] = {
percent: 0,
status: 'uploading',
loaded: 0,
total: file.size
}
uploadingFiles.value.push({
id: fileId,
name: file.name,
size: file.size
})
try {
const formData = new FormData()
formData.append('file', file)
// 调用带进度的上传接口
const response = await fileAPI.uploadFile(formData, (progress) => {
uploadProgress.value[fileId] = {
...progress,
status: 'uploading'
}
})
// 更新为成功状态
uploadProgress.value[fileId] = {
...uploadProgress.value[fileId],
percent: 100,
status: 'success'
}
message.success(`✅ "${file.name}" 上传成功!`)
// 刷新文件列表
emit('file-uploaded', response.data?.data)
// 3秒后从上传列表移除
setTimeout(() => {
uploadingFiles.value = uploadingFiles.value.filter(f => f.id !== fileId)
delete uploadProgress.value[fileId]
}, 3000)
} catch (error) {
// 更新为失败状态
uploadProgress.value[fileId] = {
...uploadProgress.value[fileId],
status: 'error',
error: error.response?.data?.message || error.message || '网络错误'
}
message.error(`❌ "${file.name}" 上传失败`)
}
}
/**
* 处理验证错误
*/
function handleValidationError(errors) {
errors.forEach(err => {
message.warning(`⚠️ ${err.file.name}: ${err.errors.join(', ')}`)
})
}
```
- [ ] **Step 3: 在 template 中添加上传UI**
在 template 的合适位置(建议在 selector-panel 内部顶部)添加:
```vue
<!-- ===== 新增增强型上传区域 ===== -->
<div class="enhanced-upload-section">
<DropZone
@files-selected="handleFilesSelected"
@error="handleValidationError"
:multiple="true"
:accepted-types="'.docx,.pdf,.txt,.md,.xlsx,.pptx'"
:max-size="52428800"
/>
<!-- 正在上传的文件列表 -->
<div v-if="uploadingFiles.length > 0" class="uploading-list">
<div
v-for="file in uploadingFiles"
:key="file.id"
class="uploading-item"
>
<ProgressBar
:percent="uploadProgress[file.id]?.percent || 0"
:status="uploadProgress[file.id]?.status || 'idle'"
:filename="file.name"
:loaded="uploadProgress[file.id]?.loaded || 0"
:total="file.size"
:error="uploadProgress[file.id]?.error"
/>
</div>
</div>
</div>
```
- [ ] **Step 4: 添加样式**
`<style scoped>` 部分添加:
```css
.enhanced-upload-section {
margin-bottom: 16px;
}
.uploading-list {
margin-top: 12px;
display: flex;
flex-direction: column;
gap: 10px;
}
.uploading-item {
background: white;
border: 1px solid #e5e7eb;
border-radius: 8px;
padding: 12px;
}
```
- [ ] **Step 5: 测试完整上传流程**
手动测试:
1. 点击上传区域 → 选择有效文件 → 出现进度条 → 上传成功 → 3秒后消失
2. 拖拽多个文件 → 多个进度条同时显示 → 依次完成
3. 尝试上传 .exe 文件 → 显示友好错误提示
4. 断网状态下上传 → 显示错误状态 + 错误信息
- [ ] **Step 6: Commit**
```bash
git add src/components/FileSelector.vue
git commit -m "feat: integrate drag-drop upload, validation, and progress bar into FileSelector"
```

## Task 6: 为 UploadTaskItem 添加重试按钮
**Files:**
- Modify: `src/components/exam/UploadTaskItem.vue`
**目标:** 在任务状态卡片中添加一键重试按钮,方便用户快速恢复失败的任务
- [ ] **Step 1: 修改 template 部分**
在第28-33行的错误详情按钮后面添加重试按钮
当前代码:
```html
<button
v-if="(vectorStatus.status === 'error' && vectorStatus.message) || (examStatus.status === 'error' && examStatus.message)"
class="uti-detail"
@click="toggleError"
>详情</button>
```
替换为:
```html
<button
v-if="(vectorStatus.status === 'error' && vectorStatus.message) || (examStatus.status === 'error' && examStatus.message)"
class="uti-detail"
@click="toggleError"
>详情</button>
<!-- 新增:一键重试按钮 -->
<button
v-if="vectorStatus.status === 'error'"
class="uti-retry"
@click="handleRetry"
:disabled="isRetrying"
>
<LoadingOutlined v-if="isRetrying" spin />
<ReloadOutlined v-else />
重试
</button>
```
- [ ] **Step 2: 修改 script 部分**
在第42-58行的 `<script setup>` 部分添加:
```javascript
import { ref } from 'vue'
import {
FileTextOutlined, LoadingOutlined, CheckCircleOutlined,
CloseCircleOutlined, ClockCircleOutlined, MinusCircleOutlined,
QuestionCircleOutlined, ReloadOutlined // 新增导入
} from '@ant-design/icons-vue'
defineProps({
task: { type: Object, required: true },
vectorStatus: { type: Object, required: true },
examStatus: { type: Object, required: true }
})
const emit = defineEmits(['retry']) // 新增定义retry事件
const showError = ref(false)
const isRetrying = ref(false) // 新增:重试状态
function toggleError() { showError.value = !showError.value }
// 新增:处理重试点击
async function handleRetry() {
if (isRetrying.value) return
isRetrying.value = true
try {
emit('retry', {
taskId: task.id,
fileName: task.fileName
})
// 模拟等待响应(实际由父组件控制)
await new Promise(resolve => setTimeout(resolve, 1000))
} finally {
// 1秒后重置按钮状态
setTimeout(() => {
isRetrying.value = false
}, 1000)
}
}
```
- [ ] **Step 3: 添加重试按钮样式**
`<style scoped>` 部分的 `.uti-detail` 样式后添加:
```css
.uti-retry {
margin-left: auto;
background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
border: none;
color: white;
cursor: pointer;
font-size: var(--font-xs, 12px);
padding: 2px 10px;
border-radius: var(--radius-sm, 4px);
transition: all 0.2s ease;
line-height: 1.7;
display: inline-flex;
align-items: center;
gap: 4px;
font-weight: 500;
}
.uti-retry:hover:not(:disabled) {
transform: translateY(-1px);
box-shadow: 0 4px 12px rgba(102, 126, 234, 0.35);
}
.uti-retry:disabled {
opacity: 0.6;
cursor: not-allowed;
}
```
- [ ] **Step 4: 测试重试功能**
在父组件中使用:
```vue
<UploadTaskItem
:task="task"
:vector-status="vs"
:exam-status="es"
@retry="handleTaskRetry"
/>
<script setup>
function handleTaskRetry({ taskId, fileName }) {
console.log(`重试任务: ${fileName} (ID: ${taskId})`)
// 调用重试API或重新上传逻辑
}
</script>
```
预期行为:
1. 错误状态的卡片显示"🔄 重试"按钮
2. 点击后按钮变为加载状态(转圈图标)
3. 触发 retry 事件,传递 taskId 和 fileName
4. 1秒后按钮恢复正常可再次点击
- [ ] **Step 5: Commit**
```bash
git add src/components/exam/UploadTaskItem.vue
git commit -m "feat: add retry button to UploadTaskItem for failed tasks"
```
---
## Task 7: 实现智能轮询策略
**Files:**
- Modify: `src/components/exam/composables/useUploadTasks.js`
**目标:** 将固定5秒轮询改为动态间隔策略活跃3秒/空闲10秒/隐藏30秒
- [ ] **Step 1: 修改轮询配置常量**
在第5行附近
```javascript
const POLL_INTERVAL = 5000
```
替换为:
```javascript
// 智能轮询配置(单位:毫秒)
const POLL_CONFIG = {
active: 3000, // 有活跃任务时3秒快速反馈
idle: 10000, // 全部空闲时10秒低频查询
hidden: 30000, // 页面不可见时30秒节省资源
maxInterval: 30000 // 最大间隔上限
}
```
- [ ] **Step 2: 添加智能轮询逻辑**
`startPolling()` 函数之前约第292行插入以下代码
```javascript
let currentInterval = POLL_CONFIG.idle
let visibilityHandler = null
/**
* 根据当前任务状态更新轮询策略
*/
function updatePollingStrategy() {
const hasActiveTasks = shouldPoll()
const isHidden = document.hidden
let newInterval
if (tasks.value.length === 0) {
// 无任何任务 → 停止轮询
newInterval = 0
} else if (isHidden) {
// 页面不可见 → 低频轮询
newInterval = POLL_CONFIG.hidden
} else if (hasActiveTasks) {
// 有活跃任务 → 高频轮询
newInterval = POLL_CONFIG.active
} else {
// 全部空闲 → 中频轮询
newInterval = POLL_CONFIG.idle
}
// 仅当间隔变化时才重启定时器(避免不必要的重启)
if (newInterval !== currentInterval) {
const oldInterval = currentInterval
currentInterval = newInterval
console.log(`[useUploadTasks] 轮询策略调整: ${oldInterval}ms → ${newInterval}ms`, {
hasActiveTasks,
isHidden,
totalTasks: tasks.value.length
})
stopPolling()
if (newInterval > 0) {
pollTimer = setInterval(pollOnce, newInterval)
}
}
}
/**
* 设置页面可见性监听器
*/
function setupVisibilityListener() {
if (visibilityHandler) return // 避免重复绑定
visibilityHandler = () => {
updatePollingStrategy()
}
document.addEventListener('visibilitychange', visibilityHandler)
console.log('[useUploadTasks] 页面可见性监听已启用')
}
/**
* 清除页面可见性监听器
*/
function teardownVisibilityListener() {
if (visibilityHandler) {
document.removeEventListener('visibilitychange', visibilityHandler)
visibilityHandler = null
}
}
```
- [ ] **Step 3: 修改 startPolling 和 stopPolling 函数**
将原有的:
```javascript
function startPolling() {
stopPolling()
pollTimer = setInterval(pollOnce, POLL_INTERVAL)
}
function stopPolling() {
if (pollTimer) {
clearInterval(pollTimer)
pollTimer = null
}
}
```
替换为:
```javascript
function startPolling() {
stopPolling()
// 初始化策略并启动
updatePollingStrategy()
setupVisibilityListener()
console.log(`[useUploadTasks] 智能轮询已启动 (初始间隔: ${currentInterval}ms)`)
}
function stopPolling() {
if (pollTimer) {
clearInterval(pollTimer)
pollTimer = null
}
teardownVisibilityListener()
currentInterval = 0
console.log('[useUploadTasks] 轮询已停止')
}
```
- [ ] **Step 4: 修改生命周期钩子**
`onUnmounted` 中确保清理可见性监听器:
```javascript
onUnmounted(() => {
stopPolling()
// teardownVisibilityListener 已在 stopPolling 中调用
})
```
并在组件挂载时自动启动(如果已有任务的话)。可以在 `return` 语句之前添加:
```javascript
// 自动初始化(如果已有任务则立即开始轮询)
if (tasks.value.length > 0) {
startPolling()
}
```
- [ ] **Step 5: 测试智能轮询**
打开浏览器控制台,观察日志输出:
1. **正常情况**
```
[useUploadTasks] 智能轮询已启动 (初始间隔: 10000ms)
[useUploadTasks] 页面可见性监听已启用
```
2. **模拟有活跃任务**手动将某个任务状态改为VECTORIZING
```
[useUploadTasks] 轮询策略调整: 10000ms → 3000ms
```
3. **切换到其他标签页(隐藏页面)**
```
[useUploadTasks] 轮询策略调整: 3000ms → 30000ms
```
4. **回到页面**
```
[useUploadTasks] 轮询策略调整: 30000ms → 3000ms (如果有活跃任务)
```
- [ ] **Step 6: Commit**
```bash
git add src/components/exam/composables/useUploadTasks.js
git commit -m "perf: implement smart polling strategy (3s/10s/30s dynamic intervals)"
```

## Task 8: 创建 Toast 通知组件
**Files:**
- Create: `src/components/ui/ToastNotification.vue`
- Create: `src/utils/notification.js`
**目标:** 实现全局Toast通知系统用于展示上传成功/失败、任务状态变更等消息
- [ ] **Step 1: 编写 notification.js 工具函数**
```javascript

// 测试成功通知
notifySuccess('文件"制度管理办法.docx"上传成功')
// 测试错误通知
notifyError('向量化失败:服务器内部错误')
// 3秒后会自动消失

预期效果:
- 右下角弹出通知卡片
- 带有进度条倒计时动画
- 可点击 × 手动关闭
- 最多同时显示3条
- [ ] **Step 4: Commit**
```bash
git add src/utils/notification.js
git commit -m "feat: add global Toast notification system with auto-dismiss"

## Task 9: 创建骨架屏加载组件
**Files:**
- Create: `src/components/ui/SkeletonCard.vue`
**目标:** 实现通用骨架屏加载占位组件,提升首屏加载体验

- [ ] **Step 2: 测试骨架屏组件**
```vue
<template>
<div>
<!-- 默认变体 -->
<SkeletonCard :lines="4" :animated="true" />
<!-- 紧凑变体 -->
<SkeletonCard variant="compact" :lines="2" />
<!-- 详细变体(带操作按钮) -->
<SkeletonCard variant="detailed" :lines="5" :show-actions="true" />
</div>
</template>
```
预期效果:
- 显示脉冲动画的灰色占位块
- 模拟真实内容的布局结构
- 动画流畅自然
- [ ] **Step 3: Commit**
```bash
git add src/components/ui/SkeletonCard.vue
git commit -m "feat: add SkeletonCard loading placeholder component with variants"
```

## Task 10: 集成所有优化并端到端测试
**Files:**
- Multiple files (integration testing)
**目标:** 验证所有增强功能协同工作,确保无回归问题
- [ ] **Step 1: 运行构建验证**
```bash
npm run build
```
预期结果:
- ✅ 构建成功exit code 0
- ✅ 无编译错误或警告
- ✅ 输出文件生成正常
- [ ] **Step 2: 功能集成检查清单**
逐项验证以下功能点:
**文件上传增强:**
- [ ] 拖拽文件到上传区域 → 触发文件选择
- [ ] 选择 .docx/.pdf 文件 → 通过验证并开始上传
- [ ] 选择 .exe 文件 → 显示友好错误提示
- [ ] 选择 >50MB 文件 → 显示大小超限提示
- [ ] 上传过程中 → 进度条实时更新百分比
- [ ] 上传成功 → 显示绿色成功状态 + Toast通知
- [ ] 上传失败 → 显示红色错误状态 + 错误详情
**任务状态优化:**
- [ ] 任务处于 VECTORIZING 状态 → 图标旋转动画
- [ ] 任务失败 → 显示重试按钮
- [ ] 点击重试 → 按钮变为loading → 触发重试逻辑
- [ ] 页面切换到后台 → 控制台显示轮询间隔调整为30秒
- [ ] 回到前台且有活跃任务 → 轮询间隔恢复为3秒
- [ ] 所有任务完成 → 轮询间隔变为10秒
**UI/UX改进**
- [ ] Toast通知正确显示在右下角
- [ ] 通知3-5秒后自动消失
- [ ] 骨架屏在数据加载时正确显示
- [ ] 移动端布局无严重错位
- [ ] 所有交互元素触控区域 ≥ 44px
- [ ] **Step 3: 性能基准测试**
使用浏览器DevTools Performance面板
```javascript
// 在控制台运行性能测试
console.time('UploadFlowTest')
// 执行完整的上传流程
console.timeEnd('UploadFlowTest')
// 预期: < 2000ms (不含网络等待时间)
console.time('RenderTest')
// 强制刷新组件多次
console.timeEnd('RenderTest')
// 预期: < 100ms per render
```
- [ ] **Step 4: 浏览器兼容性测试**
在以下浏览器中验证核心功能:
| 浏览器 | 版本 | 拖拽上传 | 进度条 | 动画 | Toast |
|--------|------|---------|-------|------|-------|
| Chrome | 90+ | ✅ | ✅ | ✅ | ✅ |
| Firefox | 88+ | ✅ | ✅ | ✅ | ✅ |
| Safari | 14+ | ✅ | ✅ | ✅ | ✅ |
| Edge | 90+ | ✅ | ✅ | ✅ | ✅ |
- [ ] **Step 5: 最终Commit**
```bash
git add .
git commit -m "feat: complete file upload and task status optimization (Phase A)
Enhancements:
- Add drag-and-drop upload with visual feedback
- Implement real-time upload progress bar

## 🎯 下一步行动
**计划已完成并保存至**: `docs/superpowers/plans/2026-05-30-file-upload-task-optimization-plan.md`
**两种执行方式可供选择:**
**1. Subagent-Driven (推荐)** - 我将为每个Task派遣独立的子代理执行每个任务完成后进行审查快速迭代
**2. Inline Execution** - 在当前会话中使用 executing-plans 技能批量执行,带有检查点进行审查
**您希望使用哪种方式?**
