组件拆分重构 App.vue

先这样拆解 不然越来越乱

src/
  components/
    StudentBar.vue
    TabNav.vue
    SolvePanel.vue
    HistoryPanel.vue
    WrongPanel.vue

7）src/App.vue 的 script 只补充这些 import

在顶部新增：

import StudentBar from './components/StudentBar.vue'
import TabNav from './components/TabNav.vue'
import SolvePanel from './components/SolvePanel.vue'
import HistoryPanel from './components/HistoryPanel.vue'
import WrongPanel from './components/WrongPanel.vue'

---

8）src/App.vue 的 script 新增两个方法

加到 script setup 里：

const handleTabChange = async (tab: 'solve' | 'history' | 'wrong' | 'report' | 'suggestion') => {
  activeTab.value = tab

  if (tab === 'history') {
    await loadHistory()
  } else if (tab === 'wrong') {
    await loadWrongList()
  } else if (tab === 'report') {
    await loadReport()
  } else if (tab === 'suggestion') {
    await loadStudySuggestion()
  }
}

const handleGenerateWeakPractice = async (knowledgeName: string) => {
  practiceKnowledge.value = knowledgeName
  activeTab.value = 'solve'
  await handleGeneratePractice()
}

---

9）src/App.vue 的 style 删除这些已拆走的样式

可以从 App.vue 里删掉这些，避免重复：

.student-bar
.student-select,
.student-input
.tabs
.tab-btn
.tab-btn.active
.upload-area
.upload-btn
.file-input
.question-input
.card-header
.card-actions
.retry-btn
.wrong-btn
.practice-panel
.practice-form
.practice-input
.practice-list
.regenerated-box

保留这些全局页面级样式：

.page {
  min-height: 100vh;
  background: #f5f7fa;
  padding: 40px 16px;
}
.container {
  max-width: 900px;
  margin: 0 auto;
  background: #fff;
  padding: 24px;
  border-radius: 12px;
}
.submit-btn {
  margin-top: 16px;
  padding: 10px 18px;
  border: none;
  background: #18a058;
  color: #fff;
  border-radius: 8px;
  cursor: pointer;
}
.result-card {
  margin-top: 24px;
  padding: 20px;
  background: #fafafa;
  border-radius: 8px;
}
.empty {
  padding: 32px 0;
  text-align: center;
  color: #999;
}
.report-panel {
  margin-top: 24px;
}
.report-summary {
  display: grid;
  grid-template-columns: repeat(4, 1fr);
  gap: 16px;
  margin-bottom: 24px;
}
.summary-card {
  padding: 20px;

  border-radius: 12px;
  text-align: center;
}
.summary-label {
  color: #666;
  font-size: 14px;
  margin-bottom: 8px;
}
.summary-value {
  font-size: 28px;
  font-weight: 700;
  color: #18a058;
}
.stat-list {
  padding: 0;
  margin: 0;
  list-style: none;
}
.stat-item {
  display: flex;
  justify-content: space-between;
  padding: 12px 0;
  border-bottom: 1px solid #eee;
}
.recent-item {
  padding: 16px 0;
  border-bottom: 1px solid #eee;
}
.recent-header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  margin-bottom: 8px;
}
.recent-question {
  margin-bottom: 10px;
  color: #333;
}
.recent-kp {
  display: flex;
  gap: 8px;
  flex-wrap: wrap;
}
.kp-tag {
  display: inline-block;
  padding: 4px 10px;
  background: #f3f3f3;
  border-radius: 999px;
  font-size: 12px;
}
.status-tag {
  display: inline-block;
  padding: 4px 10px;
  border-radius: 999px;
  font-size: 12px;
  color: #fff;
}
.status-tag.wrong {
  background: #d03050;
}
.status-tag.correct {
  background: #18a058;
}
.weak-item {
  padding: 16px 0;
  border-bottom: 1px solid #eee;
}
.weak-header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  margin-bottom: 8px;
}
.weak-rate {
  color: #d03050;
  font-weight: 600;
}
.weak-meta {
  color: #666;
  font-size: 14px;
  margin-bottom: 8px;
}
.weak-suggestion {
  margin-bottom: 12px;
  color: #333;
  line-height: 1.7;
}

10）效果

这次拆分完：

• App.vue 只保留页面编排和状态
• 学生切换独立
• tab 独立
• 解析区独立
• 历史记录独立
• 错题本独立

后面再拆：

• ReportPanel.vue
• SuggestionPanel.vue

功能都测试一遍 没问题

nice !
