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
/**

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
git add src/utils/fileValidator.js
git commit -m "feat: add file validation utility with type/size/name checks"
Task 2: 创建上传进度条组件
Files:
- Create:
src/components/ui/ProgressBar.vue
目标: 实现可视化上传进度条,支持百分比显示、动画效果、状态切换
- Step 1: 编写 ProgressBar.vue 组件

- Step 2: 测试拖拽功能
在页面中使用:
<DropZone
@files-selected="handleUpload"
@error="handleError"
/>
测试场景:
- 从桌面拖拽 .docx 文件到区域 → 触发 files-selected 事件
- 拖拽 .exe 文件 → 触发 error 事件,显示错误信息
- 点击区域 → 打开文件选择对话框
- 同时拖拽多个文件 → 全部添加到预览列表
- Step 3: Commit
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:
// 当前代码:
uploadFile: (formData) => {
return apiClient.post('/file/upload', formData, {
headers: {
'Content-Type': 'multipart/form-data'
}
})
},
替换为:
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
在 api/file.js 文件末尾(第124行之后)添加:
/**
* 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
// 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: ${(progress.loaded / 1024 / 1024).toFixed(1)}MB`)
// 更新UI进度条...
}).then(response => {
console.log('上传完成:', response.data)
}).catch(error => {
console.error('上传失败:', error)
})
- Step 4: Commit
git add src/api/file.js
git commit -m "feat: add upload progress callback to fileAPI.uploadFile method"
Task 5: 集成增强功能到 FileSelector 组件
Files:
- Modify:
src/components/FileSelector.vue
目标: 将拖拽上传、文件验证、进度条集成到现有的 FileSelector 组件中
- Step 1: 导入新组件和工具函数
在 <script setup> 部分顶部添加导入:
import { ref, watch, onMounted } from 'vue'
import { message } from 'ant-design-vue'
import {
FileTextOutlined, SearchOutlined, DownOutlined,
CloseOutlined, LeftOutlined, RightOutlined,
DatabaseOutlined, UnorderedListOutlined, CopyOutlined,
InboxOutlined, FileSearchOutlined, LoadingOutlined,
CloudUploadOutlined, UploadOutlined, DeleteOutlined
} from '@ant-design/icons-vue'
// 新增导入:
import DropZone from './ui/DropZone.vue'
import ProgressBar from './ui/ProgressBar.vue'
import { formatFileSize, validateFile } from '../utils/fileValidator.js'
import { fileAPI } from '../../api/file.js'
- Step 2: 添加响应式变量和方法
在 script 中添加新的状态变量和方法:
// ===== 新增:上传相关状态 =====
const uploadingFiles = ref([]) // 正在上传的文件列表
const uploadProgress = ref({}) // 进度映射 { fileId: { percent, status } }
/**
* 处理文件选择/拖拽
*/
async function handleFilesSelected(files) {
for (const file of files) {
await uploadSingleFile(file)
}
}
/**
* 上传单个文件
*/
async function uploadSingleFile(file) {
const validation = validateFile(file)
if (!validation.valid) {
message.error(`${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:
<!-- ===== 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
在 <style scoped> 部分添加:
.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:
- 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
- 拖拽多个文件 → 多个进度条同时显示 → 依次完成
- 尝试上传 .exe 文件 → 显示友好错误提示
- 断网状态下上传 → 显示错误状态 + 错误信息
- Step 6: Commit
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:
<button
v-if="(vectorStatus.status === 'error' && vectorStatus.message) || (examStatus.status === 'error' && examStatus.message)"
class="uti-detail"
@click="toggleError"
>详情</button>
替换为:
<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:
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
在 <style scoped> 部分的 .uti-detail 样式后添加:
.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:
<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:
- 错误状态的卡片显示"🔄 重试"按钮
- 点击后按钮变为加载状态(转圈图标)
- 触发 retry 事件,传递 taskId 和 fileName
- 1秒后按钮恢复正常,可再次点击
- Step 5: Commit
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,将:
const POLL_INTERVAL = 5000
替换为:
// 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
在 startPolling() 函数之前(约第292行)插入以下代码:
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:
function startPolling() {
stopPolling()
pollTimer = setInterval(pollOnce, POLL_INTERVAL)
}
function stopPolling() {
if (pollTimer) {
clearInterval(pollTimer)
pollTimer = null
}
}
替换为:
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
在 onUnmounted 中确保清理可见性监听器:
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:
// 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:
-
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 -
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 -
切换到其他标签页(隐藏页面):
[useUploadTasks] 轮询策略调整: 3000ms → 30000ms -
回到页面:
[useUploadTasks] 轮询策略调整: 30000ms → 3000ms (如果有活跃任务)
- Step 6: Commit
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
/**
* Toast通知工具函数
* 用于全局显示通知消息
*/
let toastContainer = null
let toastIdCounter = 0
const MAX_VISIBLE_TOASTS = 3
const DEFAULT_DURATION = {

- Step 2: 编写 Toast 样式(注入到head)
在 notification.js 文件末尾添加样式注入函数:
/**

*/
let stylesInjected = false
function injectStyles() {
if (stylesInjected || typeof document === 'undefined') return
const styleEl = document.createElement('style')
styleEl.textContent = `

- Step 3: 测试通知功能
在浏览器控制台中执行:
import { notifySuccess, notifyError } from './utils/notification.js'
// 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
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

- Step 2: 测试骨架屏组件
<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
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
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:
// 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+ | ✅ | ✅ | ✅ | ✅ |

🎯 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?
