+# 考试管理API对接实施计划
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 将「考察与训练」模块中「智能组卷」和「互动训练」子功能对接后端考试管理API，替换模拟数据
+
+**架构:** 
+- 智能组卷使用 `POST /exam/paper/generate` 从题库自动组卷，结果仅前端暂存
+- 互动训练闯关模式使用预设5级固定关卡，每关调用组卷接口生成题目
+- 错题本通过 `POST /exam/answers/query` 查询答题记录，筛选错题展示
+
+**Tech Stack:** Vue 3, Axios, Ant Design Vue
+
+---
+
+### Task 1: exam.js 新增 API 方法
+
+**Files:**
+- Modify: `src/api/exam.js`
+
+- [ ] **Step 1: 新增 generatePaper 方法**
+
+在 `exam.js` 的 `examAPI` 对象末尾、`gradeAnswers` 之后添加：
+
+```javascript
+  generatePaper: (params) => {
+    console.log('[examAPI] 生成试卷 - 参数:', params)
+
+    const requestBody = {
+      single_choice_count: params.single_choice_count || 0,
+      multiple_choice_count: params.multiple_choice_count || 0,
+      true_false_count: params.true_false_count || 0,
+      fill_blank_count: params.fill_blank_count || 0,
+      subjective_count: params.subjective_count || 0,
+      include_personal: params.include_personal || false,
+      difficulty: params.difficulty || 2,
+      collection: params.collection,
+      collection_name: params.collection_name,
+      file_ids: params.file_ids || []
+    }
+
+    return apiClient.post('/exam/paper/generate', requestBody, {
+      timeout: 120000
+    }).then(handleExamResponse).then(response => {
+      console.log('[examAPI] 试卷生成成功:', response)
+      return response
+    })
+  },
+```
+
+- [ ] **Step 2: 新增 queryUserAnswers 方法**
+
+在 `generatePaper` 之后添加：
+
+```javascript
+  queryUserAnswers: (request) => {
+    console.log('[examAPI] 查询答题记录 - 参数:', request)
+
+    return apiClient.post('/exam/answers/query', request, {
+      timeout: 30000
+    }).then(response => {
+      const data = response.data
+      if (data.code === 200 && data.data) {
+        return data.data
+      }
+      throw new Error(data.message || '查询答题记录失败')
+    })
+  },
+```
+

+
+### Task 2: 智能组卷 - 改造 handleGeneratePaper
+
+**Files:**
+- Modify: `src/components/ExamModule.vue`
+
+- [ ] **Step 1: 替换 handleGeneratePaper 函数**
+
+找到 `const handleGeneratePaper = async () => {` 函数（约2281行），将其整体替换为：
+
+```javascript
+const handleGeneratePaper = async () => {
+  if (!paperConfig.doc) {
+    message.warning('请先选择制度文件')
+    return
+  }
+

+    return
+  }
+
+  isGeneratingPaper.value = true

+        if (paperConfig.doc.id) {
+          fileIds = [paperConfig.doc.id]
+        }
+      }
+    }
+
+    // 难度百分比 → 1-5 加权计算
+    const weightedDifficulty = Math.round(
+      (paperConfig.easyPercent * 1 + paperConfig.mediumPercent * 3 + paperConfig.hardPercent * 5) / 100
+    )

+      explanation: q.content?.explanation || '',
+      studentAnswer: null
+    }))
+
+    const newPaper = {
+      id: Date.now(),
+      paperId: result.paper_id,
+      name: paperConfig.name || '智能组卷',
+      doc: typeof paperConfig.doc === 'object' ? (paperConfig.doc.title || paperConfig.doc.rawFileName || '') : paperConfig.doc,
+      questions: questions.length,
+      totalScore: result.total_score || 100,
+      duration: paperConfig.duration,
+      status: 'draft',
+      questionList: questions
+    }
+
+    papers.value.unshift(newPaper)
+    message.success(`试卷生成成功！共 ${questions.length} 道题`)
+  } catch (error) {
+    console.error('智能组卷失败:', error)
+    message.error('智能组卷失败: ' + (error.message || '请检查网络连接'))
+  } finally {
+    isGeneratingPaper.value = false
+    setTimeout(() => {
+      showGeneratePaperModal.value = false
+    }, 500)
+  }
+}
+```
+
+- [ ] **Step 2: 添加 isGeneratingPaper ref**
+
+在文件 script 部分的 ref 声明区（约1550行附近），找到 `const isGenerating = ref(false)` 所在区块，在其附近添加：
+
+```javascript
+const isGeneratingPaper = ref(false)
+```
+

+
+### Task 3: 智能组卷 - 更新查看试卷弹窗
+
+**Files:**
+- Modify: `src/components/ExamModule.vue`
+
+- [ ] **Step 1: 更新查看试卷弹窗以展示真实题目**
+
+找到 `showViewPaperModal` 对应弹窗的模板（约964-1018行），将弹窗内容替换为：
+
+```html
+<a-modal
+  title="查看试卷"
+  v-model:open="showViewPaperModal"
+  @cancel="showViewPaperModal = false"

+
+### Task 4: 互动训练 - 预设闯关关卡
+
+**Files:**
+- Modify: `src/components/ExamModule.vue`
+
+- [ ] **Step 1: 替换 trainingData 为 ref 响应式数据**
+
+找到 `const trainingData = {` 定义（约1819行），替换为：
+
+```javascript
+const trainingData = ref({
+  checkpoints: [
+    { id: 1, name: '入门挑战', status: 'in-progress', score: 0, singleCount: 3, multipleCount: 0, trueFalseCount: 2, fillBlankCount: 0, subjectiveCount: 0, difficulty: 1 },
+    { id: 2, name: '基础巩固', status: 'pending', score: 0, singleCount: 4, multipleCount: 2, trueFalseCount: 2, fillBlankCount: 0, subjectiveCount: 0, difficulty: 2 },
+    { id: 3, name: '进阶提升', status: 'pending', score: 0, singleCount: 4, multipleCount: 3, trueFalseCount: 3, fillBlankCount: 0, subjectiveCount: 0, difficulty: 3 },
+    { id: 4, name: '高级挑战', status: 'pending', score: 0, singleCount: 3, multipleCount: 3, trueFalseCount: 2, fillBlankCount: 0, subjectiveCount: 2, difficulty: 4 },
+    { id: 5, name: '大师试炼', status: 'pending', score: 0, singleCount: 4, multipleCount: 4, trueFalseCount: 2, fillBlankCount: 0, subjectiveCount: 2, difficulty: 5 }
+  ],
+  dailyExercises: [],
+  wrongQuestions: []
+})
+```
+
+- [ ] **Step 2: 替换闯关模式模板中涉及 trainingData 的属性访问**
+
+找到模板中所有 `trainingData.` 开头的属性访问，替换为 `trainingData.` -> `trainingData.`（Vue ref 在模板中自动解包，用 `.value` 或在 script 中通过 computed 适配）。
+
+将模板中的统计部分（约613-634行）：
+
+```html
+<div class="stat-value">{{ trainingData.checkpoints.filter(c => c.status === 'completed').length }}</div>
+```
+
+改为：
+
+```html
+<div class="stat-value">{{ completedCheckpointCount }}</div>
+```
+
+- [ ] **Step 3: 添加计算属性**
+
+在 script 区添加计算属性以适配模板中的统计展示：
+
+```javascript
+const completedCheckpointCount = computed(() => {
+  return trainingData.value.checkpoints.filter(c => c.status === 'completed').length
+})
+```
+
+- [ ] **Step 4: 替换闯关模式模板的关卡列表渲染**
+
+找到闯关模式面板的模板（约659-693行），替换为：
+
+```html
+<div v-if="trainTab === 'checkpoint'" class="exam-card">
+  <div class="card-header">
+    <h2>🗺️ 闯关地图</h2>
+    <span class="status-badge status-info">共 {{ trainingData.value.checkpoints.length }} 关</span>
+  </div>
+  
+  <div class="checkpoint-map">
+    <div 
+      v-for="(checkpoint, index) in trainingData.value.checkpoints" 
+      :key="checkpoint.id" 
+      :class="['checkpoint-item', checkpoint.status]"
+    >
+      <div class="checkpoint-node" @click="handleStartCheckpoint(checkpoint)">
+        <div class="node-circle">
+          {{ checkpoint.id }}
+        </div>
+        <div class="node-info">
+          <div class="node-name">{{ checkpoint.name }}</div>
+          <div :class="['node-status', checkpoint.status]">
+            {{ checkpoint.status === 'completed' ? `✅ 得分：${checkpoint.score}分` :

+      </div>
+      <div v-if="index < trainingData.value.checkpoints.length - 1" class="checkpoint-line"></div>
+    </div>
+  </div>
+</div>
+```
+
+- [ ] **Step 5: 更新 handleStartCheckpoint 函数**
+
+找到该函数（约2386行），替换为：
+
+```javascript
+const handleStartCheckpoint = async (checkpoint) => {
+  try {
+    const params = {
+      single_choice_count: checkpoint.singleCount || 0,
+      multiple_choice_count: checkpoint.multipleCount || 0,
+      true_false_count: checkpoint.trueFalseCount || 0,
+      fill_blank_count: checkpoint.fillBlankCount || 0,
+      subjective_count: checkpoint.subjectiveCount || 0,
+      include_personal: false,
+      difficulty: checkpoint.difficulty || 2,
+      collection: 'public_kb'
+    }
+
+    message.loading({ content: '正在生成闯关题目...', key: 'checkpoint' })
+
+    const result = await examAPI.generatePaper(params)
+
+    currentCheckpointQuestions.value = (result.questions || []).map((q, index) => ({
+      id: index + 1,
+      questionId: q.question_id,
+      type: q.question_type,
+      typeLabel: q.question_type_name || q.question_type,
+      difficulty: q.difficulty,
+      score: q.score || 5,
+      stem: q.content?.stem || '',
+      options: q.content?.data?.options || q.content?.options || [],
+      answer: q.content?.answer || '',
+      explanation: q.content?.explanation || '',
+      studentAnswer: null
+    }))
+
+    currentCheckpoint.value = {
+      ...checkpoint,
+      paperId: result.paper_id,
+      totalScore: result.total_score || 100
+    }
+
+    showCheckpointModal.value = true
+    message.destroy('checkpoint')
+  } catch (error) {
+    console.error('闯关题目生成失败:', error)
+    message.error('题目加载失败，请重试')
+  }
+}
+```
+
+- [ ] **Step 6: 添加 currentCheckpointQuestions ref**
+
+在 script 区的 ref 声明区添加：
+
+```javascript
+const currentCheckpointQuestions = ref([])
+```
+
+---
+
+### Task 5: 互动训练 - 闯关弹窗改造
+
+**Files:**
+- Modify: `src/components/ExamModule.vue`
+
+- [ ] **Step 1: 替换闯关弹窗模板**
+
+找到 `showCheckpointModal` 对应弹窗（约1020-1048行），替换为：

+
+### Task 6: 互动训练 - 错题本对接
+
+**Files:**
+- Modify: `src/components/ExamModule.vue`
+
+- [ ] **Step 1: 替换错题本模板**
+
+找到错题本面板模板（约770-810行），替换为：
+
+```html
+<div v-if="trainTab === 'wrong'" class="exam-card">
+  <div class="card-header">
+    <h2>📚 我的错题本</h2>
+    <span class="status-badge status-warning">共 {{ trainingData.value.wrongQuestions.length }} 道错题</span>
+  </div>
+
+  <div class="questions-list" v-if="trainingData.value.wrongQuestions.length > 0">
+    <div v-for="item in trainingData.value.wrongQuestions" :key="item.id" class="question-item wrong-item">
+      <div class="question-header">
+        <span :class="['type-badge', item.type]">
+          {{ item.type === 'single_choice' ? '单选题' : item.type === 'multiple_choice' ? '多选题' : item.type === 'true_false' ? '判断题' : item.type === 'subjective' ? '简答题' : item.type }}
+        </span>
+        <div class="question-actions">
+          <button class="btn btn-primary btn-xs" @click="handleRetryWrongQuestion(item)">重练</button>
+          <button class="btn btn-success btn-xs" @click="handleViewWrongQuestion(item)">查看解析</button>
+        </div>
+      </div>
+      
+      <div class="question-content">{{ item.content }}</div>
+
+      <div class="wrong-meta">
+        <div class="meta-item">
+          <span class="meta-label">关联关卡：</span>
+          <span class="meta-value">{{ item.doc }}</span>
+        </div>
+        <div class="meta-item">
+          <span class="meta-label">错误次数：</span>
+          <span class="meta-value error-count">{{ item.times }} 次</span>
+        </div>
+        <div v-if="item.feedback" class="meta-item">

+    <div class="empty-text">太棒了！目前没有错题</div>
+    <div class="empty-hint">继续保持，加油学习！</div>
+  </div>
+</div>
+```
+
+- [ ] **Step 2: 添加 handleRetryWrongQuestion 函数**
+
+在 script 区添加：
+
+```javascript
+const handleRetryWrongQuestion = (item) => {
+  // 将该错题的对应关卡设置为 in-progress 状态
+  const checkpoint = trainingData.value.checkpoints.find(c => c.name === item.doc)
+  if (checkpoint) {
+    checkpoint.status = 'in-progress'
+    checkpoint.score = 0
+    message.success(`已重置关卡「${checkpoint.name}」，前往闯关模式重新挑战`)
+    trainTab.value = 'checkpoint'
+  } else {
+    message.info('请前往闯关模式重新挑战')
+    trainTab.value = 'checkpoint'
+  }
+}
+```
+

+
+### Task 7: 更新每日一练提交后的错题缓存
+
+**Files:**
+- Modify: `src/components/ExamModule.vue`
+
+- [ ] **Step 1: 在 handleSubmitDailyExercise 成功后添加错题缓存**
+
+找到 `handleSubmitDailyExercise` 函数中的 `gradeResult.value = result` 行（约2441行），在其后添加：
+
+```javascript
+      // 缓存错题
+      if (result.results) {
+        result.results.forEach((item, idx) => {
+          if (item.correct === false) {
+            const q = generatedQuestions.value[idx]
+            if (q) {
+              const existing = trainingData.value.wrongQuestions.find(w => w.questionId === `q_${q.id}`)
+              if (!existing) {
+                trainingData.value.wrongQuestions.push({
+                  id: Date.now() + idx,
+                  questionId: `q_${q.id}`,
+                  content: q.stem,
+                  type: q.type,
+                  typeLabel: q.typeLabel,
+                  options: q.options,
+                  correctAnswer: q.answer,
+                  studentAnswer: q.studentAnswer,
+                  score: item.score || 0,
+                  maxScore: item.max_score || q.maxScore || 5,
+                  feedback: item.feedback || '',
+                  doc: '每日一练',
+                  times: 1,
+                  answeredAt: new Date().toISOString()
+                })
+              }
+            }
+          }
+        })
+      }
+```
+

+
+### Task 8: 更新互动训练统计展示
+
+**Files:**
+- Modify: `src/components/ExamModule.vue`
+
+- [ ] **Step 1: 替换模板中的 trainingData 属性引用**
+
+找到模板中所有剩余的 `trainingData.xxx` 引用（约618-634行，训练统计部分），替换为通过 `trainingData.value` 访问的等价表达式：
+
+```html
+<div class="stat-value">{{ completedCheckpointCount }}</div>
+...
+<div class="stat-value">{{ trainingData.value.dailyExercises.length || generatedQuestions.length }}</div>
+...
+<div class="stat-value">{{ trainingData.value.wrongQuestions.length }}</div>
+```
+
+- [ ] **Step 2: 添加 dailyExerciseCount 计算属性
+
+```javascript
+const dailyExerciseCount = computed(() => {
+  return trainingData.value.dailyExercises.length || generatedQuestions.value.length
+})
+```
+
+然后模板中用 `{{ dailyExerciseCount }}` 替换 `{{ trainingData.value.dailyExercises.length || generatedQuestions.length }}`。
+

+
+### Task 9: 错题本查看解析弹窗改造
+
+**Files:**
+- Modify: `src/components/ExamModule.vue`
+
+- [ ] **Step 1: 替换查看解析弹窗**
+
+找到 `showAnalysisModal` 对应弹窗（约1116-1145行），替换为：
+
+```html
+<a-modal
+  title="查看解析"
+  v-model:open="showAnalysisModal"
+  @cancel="showAnalysisModal = false"
+  width="700px"
+>
+  <template #footer>
+    <a-button @click="showAnalysisModal = false">关闭</a-button>
+  </template>
+  <div v-if="currentWrongQuestion">
+    <h4 style="margin-bottom: 16px;">{{ currentWrongQuestion.content }}</h4>
+    
+    <div v-if="currentWrongQuestion.options && currentWrongQuestion.options.length > 0" style="margin-bottom: 16px;">
+      <h6>题目选项：</h6>
+      <div v-for="opt in currentWrongQuestion.options" :key="opt.key" style="margin-bottom: 4px;">
+        {{ opt.key }}. {{ opt.content }}
+      </div>
+    </div>
+
+    <div style="margin-bottom: 16px;">
+      <h6>你的答案：</h6>
+      <p style="color: #ff4d4f;">{{ formatAnswer(currentWrongQuestion.studentAnswer) }}</p>
+    </div>
+
+    <div style="margin-bottom: 16px;">
+      <h6>正确答案：</h6>
+      <p style="color: #52c41a;">{{ formatAnswer(currentWrongQuestion.correctAnswer) }}</p>
+    </div>
+
+    <div v-if="currentWrongQuestion.feedback" style="margin-bottom: 16px;">
+      <h6>AI评语：</h6>
+      <p>{{ currentWrongQuestion.feedback }}</p>
+    </div>
+  </div>
+</a-modal>
+```
+
+- [ ] **Step 2: 添加 formatAnswer 工具函数
+
+```javascript
+const formatAnswer = (answer) => {
+  if (answer === null || answer === undefined) return '未作答'
+  if (Array.isArray(answer)) return answer.join(', ')
+  return String(answer)
+}
+```
