# BE02 — 考试模块设计 > **版本:V1.1 | 参考:pj006-zhilianyuan2 exam/routes.py + exam/service.py** --- ## 1. 模块职责 - 题库管理(管理员 CRUD) - 考试配置/组卷(管理员设置) - 学员端考试(开始/答题/交卷/判分) - 考试记录与回溯 ## 2. 考试流程 ``` 管理员端: 录入题目 → 配置考试(名称/类型/题量/总分/合格线/时长/随机) 员工端: 考试列表 → 查看封面/说明 → 开始考试 → 答题 → 交卷 ↓ ↓ 自测:即时显示对错+答案 正式考:存档(得分/明细/是否通过) ``` ## 3. 数据表关系 ``` question(题库)← exam_paper(考试配置,通过 domain+question_count 抽题) ↓ exam_record(每次交卷的记录) ``` ## 4. 题库 API ```python # 管理员 — 题目 CRUD GET /api/exam/questions?domain=company&status=active # 题目列表 POST /api/exam/questions # 新增题目 PUT /api/exam/questions/{id} # 编辑题目 DELETE /api/exam/questions/{id} # 停用题目 # 管理员 — 考试配置 GET /api/exam/papers # 考试配置列表 POST /api/exam/papers # 创建考试 PUT /api/exam/papers/{id} # 编辑考试 DELETE /api/exam/papers/{id} # 停用考试 ``` ## 5. 学员端考试 API ```python GET /api/exam/list # 我的考试列表 GET /api/exam/cover?id={paperId} # 考试封面/说明 POST /api/exam/start # 开始考试 → 下发题目 POST /api/exam/submit # 交卷判分 GET /api/exam/record # 我的考试记录 GET /api/exam/record/{recordId} # 考试记录详情 ``` ## 6. 判分逻辑(参考 zhilianyuan2 _is_correct) ```python # services/exam_service.py def _is_correct(qtype: str, correct: list, user: any) -> bool: """确定性判分""" if qtype == "multiple": # 多选题:集合相等 return sorted(correct) == sorted(user) if user else False elif qtype == "judge": # 判断题:值相等 return str(correct).lower() == str(user).lower() else: # 单选题:值相等 return correct == user def grade_paper(questions: list, answers: dict) -> dict: """批卷:逐题比对 → 统计得分/正确数""" correct_count = 0 total = len(questions) score_per_question = 100 / total if total else 0 details = [] for q in questions: user_ans = answers.get(str(q["id"])) is_correct = _is_correct(q["type"], q["answer"], user_ans) if is_correct: correct_count += 1 details.append({ "question_id": q["id"], "is_correct": is_correct, "user_answer": user_ans, "correct_answer": q["answer"], }) score = round(score_per_question * correct_count) return { "score": score, "correct_count": correct_count, "wrong_count": total - correct_count, "passed": score >= paper.pass_score, "details": details, } ``` ## 7. 自测 vs 正式考区别 | 维度 | 自测 (self_test) | 正式考 (formal) | |------|-----------------|----------------| | 次数限制 | 不限 | 按配置(通常 1 次) | | 即时反馈 | 每题显示对错+答案 | 交卷后显示成绩 | | 成绩存档 | 不存 | 永久保存到 exam_record | | 答题明细 | 不存 | JSON 持久化 | ## 8. 考试记录设计 ```json // exam_record.detail_json 示例 { "questions": [ { "question_id": 1, "stem": "博昇的主营业务包括?", "type": "single", "user_answer": "D", "correct_answer": "D", "is_correct": true, "explanation": "博昇双主营业务为资本咨询与AI产业落地" } ], "time_spent_sec": 1200 } ``` ## 9. 权限 - **员工:** 仅查看自己的考试记录 - **管理员:** 查看全部考试记录(`/api/system/exam-records`)
