## RAG-Agent 代码审查报告(精简版)
|
||||||
|
|
||||||
|
审查日期:2026-06-05
|
||||||
|
|
||||||
|
排除说明:storage 模块尚未启用(暂不纳入);用户认证/权限由后端服务负责(生产环境 RAG 服务为无状态接口,不做鉴权)。

||||||
|
|
||||||
|
### 一、高危问题(6 项)
|
||||||
|
|
||||||
|
**H1. SSE 错误事件泄露完整堆栈信息**
|
||||||
|
- 文件:`api/chat_routes.py:1955`
|
||||||
|
- `/rag` 接口 SSE 生成器在异常时将 `traceback.format_exc()` 完整堆栈直接发给客户端,暴露调用栈、文件路径、代码行号、内部变量。
|
||||||
|
- 修复:移除 traceback 字段,仅在服务端日志记录,客户端返回通用错误消息。
|
||||||
|
|
||||||
|
**H2. 文档更新/删除接口存在路径遍历风险**
|
||||||
|
- 文件:`api/document_routes.py:652,714`
|
||||||
|
- `update_document` 和 `delete_document` 直接将 URL 中的 `doc_path` 拼接到文件路径,未做安全校验。可构造 `../../` 路径遍历载荷。
|
||||||
|
- 修复:使用 `os.path.realpath()` 解析最终路径,验证是否在 DOCUMENTS_PATH 目录下。
|
||||||
|
|
||||||
|
**H3. `serve_document_file` 路径遍历风险**
|
||||||
|
- 文件:`api/document_routes.py:139`
|
||||||
|
- 文件服务接口同样存在路径遍历风险。虽然有 DEV_MODE 开关,但默认值为 `'true'`。
|
||||||
|
- 修复:添加 realpath 校验。
|
||||||
|
|
||||||
|
**H4. 文档更新接口缺少文件类型和大小校验**
|
||||||
|
- 文件:`api/document_routes.py:621`
|
||||||
|
- `update_document` (PUT) 未验证文件类型和大小,直接 `file.save(filepath)`。与之对比,`upload_document` 有完整校验。
|
||||||
|
- 修复:添加与 upload 一致的 ALLOWED_EXTENSIONS 和 MAX_FILE_SIZE 校验。
|
||||||
|
|
||||||
|
**H5. 批量上传接口缺少文件大小校验**
|
||||||
|
- 文件:`api/document_routes.py:350`
|
||||||
|
- `batch_upload_documents` 对每个文件只检查了扩展名,未检查文件大小。可批量上传超大文件导致磁盘耗尽。
|
||||||
|
- 修复:在循环内添加 MAX_FILE_SIZE 校验。
|
||||||
|
|
||||||
|
**H6. `main.py` debug 模式默认开启 + 监听 0.0.0.0**
|
||||||
|
- 文件:`main.py:29-31`
|
||||||
|
- `--debug` 默认 `True`,`--host` 默认 `0.0.0.0`。Flask 调试模式启用 Werkzeug 交互式 debugger,可通过触发异常执行任意代码。
|
||||||
|
- 修复:`--debug` 默认值改为 `False`。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 二、中危问题(13 项)
|
||||||
|
|
||||||
|
**M1. 多处异常响应直接暴露内部错误信息**
|
||||||
|
- 文件:`document_routes.py:332,467,733`;`kb_routes.py:523,636`;`feedback_routes.py:98,116`;`sync_routes.py:119`;`audit_routes.py:100` 等。
|
||||||
|
- 大量 `except` 块直接 `str(e)` 返回给客户端,可能包含数据库路径、SQL 片段、文件系统结构。
|
||||||
|
- 修复:统一使用通用错误消息,原始异常仅记录到服务端日志。
|
||||||
|
|
||||||
|
**M2. `/search` 接口缺少输入安全验证**
|
||||||
|
- 文件:`api/chat_routes.py:1974`
|
||||||
|
- 未调用 `validate_query()` 做注入检测和长度限制,与 `/chat`、`/rag` 不一致。
|
||||||
|
- 修复:添加 `validate_query(query)` 调用。
|
||||||
|
|
||||||
|
**M3. `/search` 的 `top_k` 参数未校验范围**
|
||||||
|
- 文件:`api/chat_routes.py:1989`
|
||||||
|
- 可传 `top_k=999999` 导致内存溢出。
|
||||||
|
- 修复:`top_k = max(1, min(int(top_k), 50))`。
|
||||||
|
|
||||||
|
**M4. `context_count` 参数未校验范围**
|
||||||
|
- 文件:`api/document_routes.py:821`
|
||||||
|
- 未限制范围且非整数字符串会 ValueError 导致 500。
|
||||||
|
- 修复:try/except + `max(0, min(n, 10))`。
|
||||||
|
|
||||||
|
**M5. CORS 配置允许所有来源**
|
||||||
|
- 文件:`api/__init__.py:70`
|
||||||
|
- `CORS(app)` 默认允许 `*` 跨域。生产环境应限制为已知前端域名。
|
||||||
|
- 修复:根据 APP_ENV 条件配置 origins。
|
||||||
|
|
||||||
|
**M6. LIKE 通配符注入风险**
|
||||||
|
- 文件:`api/kb_routes.py:503`
|
||||||
|
- `kb_name` 含 `%` 或 `_` 时会导致非预期的 LIKE 匹配行为。
|
||||||
|
- 修复:对 LIKE 特殊字符转义后再拼入模式。
|
||||||
|
|
||||||
|
**M7. SESSION_MANAGER 为 None 时未处理**
|
||||||
|
- 文件:`api/session_routes.py:35,64,83,102`
|
||||||
|
- 初始化失败时 SESSION_MANAGER 为 None,调用方法会触发 AttributeError 导致 500。
|
||||||
|
- 修复:使用前检查 None,返回 503。
|
||||||
|
|
||||||
|
**M8. LLM 调用缺少统一的超时和重试机制**
|
||||||
|
- 文件:`core/llm_utils.py`
|
||||||
|
- 部分 LLM 调用无超时控制,长时间阻塞会耗尽 worker。`@retry` 装饰器只在部分方法上使用。
|
||||||
|
- 修复:在 `_call_llm` 层面统一超时和重试。
|
||||||
|
|
||||||
|
**M9. LLM 输出 JSON 解析不够健壮**
|
||||||
|
- 文件:`core/agentic.py`、`core/agentic_answer.py`、`core/agentic_quality.py` 等
|
||||||
|
- 多处 LLM 返回的 JSON 解析缺少多策略提取和重试,仅靠 prompt 约束。exam_pkg 已修复但 core 模块尚未统一。
|
||||||
|
- 修复:提取 exam_pkg 的 `_extract_json` 为公共工具,core 模块统一使用。
|
||||||
|
|
||||||
|
**M10. Prompt 注入风险**
|
||||||
|
- 文件:`core/engine.py:2017`、`core/agentic_answer.py:83`
|
||||||
|
- 用户输入直接拼入 prompt,未做净化。恶意输入可操控 LLM 输出。
|
||||||
|
- 修复:对用户输入做基本的 prompt 注入检测(如检测 "ignore previous instructions" 等模式)。
|
||||||
|
|
||||||
|
**M11. `subprocess.run` 命令参数注入风险**
|
||||||
|
- 文件:`parsers/mineru_parser.py:632`
|
||||||
|
- file_path 中特殊字符(如以 `-` 开头的文件名)可能被命令行工具解释为选项。
|
||||||
|
- 修复:在文件路径前插入 `--` 分隔符;对 backend、lang 参数做白名单校验。
|
||||||
|
|
||||||
|
**M12. Excel/文本解析器无文件大小限制**
|
||||||
|
- 文件:`parsers/excel_parser.py:81`、`parsers/txt_parser.py:15`
|
||||||
|
- 一次性加载全文件到内存,超大文件导致 OOM。
|
||||||
|
- 修复:解析前检查文件大小,设定上限(如 50MB)。
|
||||||
|
|
||||||
|
**M13. 全局变量缓存竞态条件**
|
||||||
|
- 文件:`api/document_routes.py:100`、`api/kb_routes.py:46`
|
||||||
|
- 模块级全局变量 `_kb_manager` 等在多线程 gunicorn 下存在竞态。
|
||||||
|
- 修复:使用 `threading.Lock` 保护或改用 `flask.current_app.config`。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 三、低危问题(12 项)
|
||||||
|
|
||||||
|
**L1.** `config.py` 硬编码第三方 API 端点 `xiaomimimo.com` 作为默认值(第 20 行)— 改为空字符串,要求环境变量显式配置。
|
||||||
|
|
||||||
|
**L2.** `python-dotenv` 未安装时静默跳过,服务可能 fail-open 启动(`config.py:11`)— 生产环境缺失时抛异常。
|
||||||
|
|
||||||
|
**L3.** `assert` 校验可被 `python -O` 跳过(`api/__init__.py:236`)— 改为 `raise ValueError`。
|
||||||
|
|
||||||
|
**L4.** `/chat` 的 `history` 未限长度(`chat_routes.py:1247`)— 可消耗大量 token。
|
||||||
|
|
||||||
|
**L5.** `history` 元素结构未验证(`chat_routes.py:1117`)— 缺少字段时 KeyError 导致 500。
|
||||||
|
|
||||||
|
**L6.** `safe_filename` 运算符优先级不明确(`document_routes.py:94`)— 加括号明确。
|
||||||
|
|
||||||
|
**L7.** DocStore glob 模式未转义特殊字符(`document_routes.py:267`)— 用 `glob.escape()`。
|
||||||
|
|
||||||
|
**L8.** 相对路径 `.data/images` 因工作目录不同可能解析错误(`chat_routes.py:59`)— 改用 PROJECT_ROOT 绝对路径。
|
||||||
|
|
||||||
|
**L9.** `asyncio.run()` 在 Flask 请求上下文中兼容性问题(`chat_routes.py:1744`)。
|
||||||
|
|
||||||
|
**L10.** Excel 同一文件被重复读取多次(`excel_parser.py:81,89`)— 应复用 ExcelFile 对象。
|
||||||
|
|
||||||
|
**L11.** PDF 图片提取 `doc` 对象异常时未关闭(`image_extractor.py:78`)— 改用 `with` 语句。
|
||||||
|
|
||||||
|
**L12.** TXT 解析器异常用 `print` 而非 `logger`(`txt_parser.py:26`)。
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
### 四、修复优先级
|
||||||
|
|
||||||
|
按修复成本从低到高排序:
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 五、做得好的方面
|
||||||
|
|
||||||
|
SQL 查询全部使用参数化查询,无注入风险;`validate_query()` 对聊天输入做了注入检测和违禁词过滤;`safe_filename` 对上传文件做了基本防护;`filter_response()` 能过滤 API 密钥等敏感信息;exam_pkg 的输入校验体系完整(已在本轮开发中加固);`.gitignore` 正确排除了 `.env` 等敏感文件。

|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 二、破坏性变更(必须修改)
|
||||||
|
|
||||||
|
### 2.1 批卷请求字段重命名:`question_content` → `content`
|
||||||
|
|
||||||
|
**变更前**:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"question_id": "q-001",
|
||||||
|
"question_type": "single_choice",
|
||||||
|
"question_content": {
|
||||||
|
"stem": "题干",
|
||||||
|
"answer": "B",
|
||||||
|
"data": {"options": [...]}
|
||||||
|
},
|
||||||
|
"student_answer": "B",
|
||||||
|
"max_score": 2
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**变更后**:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"question_id": "q-001",
|
||||||
|
"question_type": "single_choice",
|
||||||
|
"content": {
|
||||||
|
"stem": "题干",
|
||||||
|
"answer": "B",
|
||||||
|
"data": {"options": [...]}
|
||||||
|
},
|
||||||
|
"student_answer": "B",
|
||||||
|
"max_score": 2
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**为什么要改**:出题接口 `/exam/generate` 返回的每道题里,题目内容字段叫 `content`。批卷接口改用同名 `content` 后,后端可以直接把出题结果的 `content` 透传到批卷接口,不需要做任何字段映射。
|
||||||
|
|
||||||
|
**后端代码修改示例**:
|
||||||
|
|
||||||
|
```python
|
||||||
|
# 修改前
|
||||||
|
grade_answers.append({
|
||||||
|
"question_id": qid,
|
||||||
|
"question_type": question.question_type,
|
||||||
|
"question_content": question.content, # ← 旧字段名
|
||||||
|
"student_answer": ans['answer'],
|
||||||
|
"max_score": question.score
|
||||||
|
})
|
||||||
|
|
||||||
|
# 修改后
|
||||||
|
grade_answers.append({
|
||||||
|
"question_id": qid,
|
||||||
|
"question_type": question.question_type,
|
||||||
|
"content": question.content, # ← 新字段名,与出题接口一致
|
||||||
|
"student_answer": ans['answer'],
|
||||||
|
"max_score": question.score
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2.2 批卷结果格式统一
|
||||||
|
|
||||||
|
**变更前**:各题型返回格式不统一,客观题直接返回 `correct` + `feedback`,填空题返回 `details.blank_scores`,主观题返回 `details.scoring_breakdown`,没有统一的结构标识。
|
||||||
|
|
||||||
|
```json
|
||||||
|
// 旧 - 客观题
|
||||||
|
{"question_id": "q1", "score": 2, "max_score": 2, "correct": true, "feedback": "正确!"}
|
||||||
|
|
||||||
|
// 旧 - 填空题
|
||||||
|
{"question_id": "q4", "score": 2, "max_score": 4, "details": {"blank_scores": [2, 0]}}
|
||||||
|
|
||||||
|
// 旧 - 主观题
|
||||||
|
{"question_id": "q5", "score": 7, "max_score": 10, "details": {"scoring_breakdown": [...]}}
|
||||||
|
```
|
||||||
|
|
||||||
|
**变更后**:所有题型统一使用 `grading_status` + `details` 结构。
|
||||||
|
|
||||||
|
```json
|
||||||
|
// 新 - 客观题
|
||||||
|
{
|
||||||
|
"question_id": "q1",
|
||||||
|
"score": 2,
|
||||||
|
"max_score": 2,
|
||||||
|
"grading_status": "success",
|
||||||
|
"details": {
|
||||||
|
"correct": true,
|
||||||
|
"student_answer": "B",
|
||||||
|
"correct_answer": "B",
|
||||||
|
"feedback": "正确!"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
// 新 - 填空题
|
||||||
|
{
|
||||||
|
"question_id": "q4",
|
||||||
|
"score": 2.0,
|
||||||
|
"max_score": 4.0,
|
||||||
|
"grading_status": "success",
|
||||||
|
"details": {
|
||||||
|
"total_blanks": 2,
|
||||||
|
"correct_blanks": 1,
|
||||||
|
"blank_scores": [2.0, 0],
|
||||||

```
|
||||||
|
|
||||||
|
**后端需要关注的点**:
|
||||||
|
|
||||||
|
1. **判断评分是否成功**:改用 `grading_status` 字段判断,不再依赖 `correct` 或 `score > 0`
|
||||||
|
- `"success"` → 正常评分,`score` 和 `details` 有效
|
||||||
|
- `"failed"` → 评分失败,`score` 为 0,`details.error` 包含失败原因
|
||||||
|
2. **获取反馈信息**:原来客观题的 `correct`/`feedback` 现在统一在 `details` 里
|
||||||
|
3. **成绩更新逻辑**:`grading_status: "failed"` 的题目,后端可选择标记为"待重批"而非直接记 0 分
|
||||||
|
|
||||||
|
**后端代码修改示例**:
|
||||||
|
|
||||||
|
```python
|
||||||
|
# 修改前
|
||||||
|
for result in grade_result['results']:
|
||||||
|
is_correct = result.get('correct', False)
|
||||||
|
feedback = result.get('feedback', '')
|
||||||
|
# 更新成绩...
|
||||||
|
|
||||||
|
# 修改后
|
||||||
|
for result in grade_result['results']:
|
||||||
|
status = result.get('grading_status', 'success')
|
||||||
|
details = result.get('details', {})
|
||||||
|
|
||||||
|
if status == 'failed':
|
||||||
|
# 评分失败,标记待重批
|
||||||
|
mark_for_regrade(result['question_id'], details.get('error', ''))
|
||||||
|
continue
|
||||||
|
|
||||||
|
is_correct = details.get('correct', None) # 仅客观题有此字段
|
||||||
|
feedback = details.get('feedback', '')
|
||||||
|
# 更新成绩...
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 三、新增校验规则(需注意)
|
||||||
|
|
||||||
|
### 3.1 出题接口入参校验
|
||||||
|
|
||||||
|
`POST /exam/generate` 新增以下校验,不满足时返回 **HTTP 400**,`error_code` 为 `INVALID_PARAMS`:
|
||||||
|
|
||||||
|
| 校验项 | 规则 | 示例(会返回 400) |
|
||||||
|
|--------|------|-------------------|
|
||||||
|
| 题型合法性 | `question_types` 的 key 必须属于 5 种题型 | `{"essay": 2}` → 不支持 |
|
||||||
|
| 题型数量 | 每种题型数量必须为非负整数 | `{"single_choice": -1}` → 不合法 |
|
||||||
|
| 难度范围 | `difficulty` 必须为 1-5 的整数 | `"difficulty": 10` → 超范围 |
|
||||||
|
| **总题数上限** | **所有题型数量之和不能超过 20** | `{"single_choice": 15, "true_false": 10}` → 超限 |
|
||||||
|
|
||||||
|
合法的 5 种题型 key:`single_choice`、`multiple_choice`、`true_false`、`fill_blank`、`subjective`
|
||||||
|
|
||||||
|
**后端建议**:在前端提交出题请求时做前置校验,避免不必要的网络请求。
|
||||||
|
|
||||||
|
### 3.2 批卷接口 question_type 校验
|
||||||
|
|
||||||
|
`POST /exam/grade` 的 `answers` 数组中,每道题的 `question_type` 现在也会校验。无效值返回 **HTTP 400**。
|
||||||
|
|
||||||
|
```json
|
||||||
|
// 返回 400
|
||||||
|
{"answers": [{"question_type": "essay", ...}]}
|
||||||
|
|
||||||
|
// 错误信息
|
||||||
|
{"error_code": "INVALID_PARAMS", "message": "第 1 题的 question_type 无效: essay,合法值: fill_blank, multiple_choice, single_choice, subjective, true_false"}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.3 错误响应格式
|
||||||
|
|
||||||
|
校验失败统一返回:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"success": false,
|
||||||
|
"error_code": "INVALID_PARAMS",
|
||||||
|
"message": "具体错误描述",
|
||||||
|
"status": "failed",
|
||||||
|
"status_code": 4000
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 三点五、跨调用去重:`exclude_stems`(强烈建议使用)
|
||||||
|
|
||||||
|
### 背景问题
|
||||||
|
|
||||||
|
同一份文档多次调用出题接口时,由于知识点来源相同,新生成的题目很可能与已有题目高度重复。单次调用上限 20 道,当需要更多题目时,这个问题尤为突出。
|
||||||
|
|
||||||
|
### 解决方式
|
||||||
|
|
||||||
|
两个出题接口(`/exam/generate` 和 `/exam/generate-smart`)新增可选参数 `exclude_stems`,后端把该文件已入库的题目题干传过来,RAG 在生成后自动排除匹配的题目。
|
||||||
|
|
||||||
|
**请求示例**:
|
||||||
|
```json
|
||||||
|
POST /exam/generate
|
||||||
|
{
|
||||||
|
"file_path": "public_kb/产品手册.pdf",
|
||||||
|
"collection": "public_kb",
|
||||||
|
"question_types": {"single_choice": 10},
|
||||||
|
"exclude_stems": [
|
||||||
|
"重购率的定义是下列哪一项?",
|
||||||
|
"以下哪项属于现代终端分类?",
|
||||||
|
"客户满意度的计算公式为___"
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 参数说明
|
||||||
|
|
||||||
|
| 参数 | 类型 | 必填 | 说明 |
|
||||||
|
|------|------|------|------|
|
||||||
|
| `exclude_stems` | string[] | 否 | 已有题目的题干列表,最多 100 条 |
|
||||||
|
|
||||||
|
### 去重策略
|
||||||
|
|
||||||
|
- 基于题干前 80 个字符进行匹配
|
||||||
|
- 新生成的题目如果与 `exclude_stems` 中任意一条匹配,会被自动过滤
|
||||||
|
- 不传或传空数组时行为不变(向后兼容)
|
||||||
|
|
||||||
|
### 后端使用流程
|
||||||
|
|
||||||
|
```
|
||||||
|
第一次出题:
|
||||||
|
POST /exam/generate { question_types: {...} }
|
||||||
|
→ 返回 20 道新题 → 审核后入库
|
||||||
|
|
||||||
|
第二次出题(想多出 10 道选择题):
|
||||||
|
1. 查询数据库,获取该文件已有的所有题目题干
|
||||||
|
2. POST /exam/generate {
|
||||||
|
question_types: {"single_choice": 10},
|
||||||
|
exclude_stems: ["已有题干1", "已有题干2", ...]
|
||||||
|
}
|
||||||
|
→ 返回 10 道不与已有题目重复的新题
|
||||||
|
```
|
||||||
|
|
||||||
|
**后端代码示例**:
|
||||||
|
```python
|
||||||
|
def generate_more_questions(file_path, collection, question_types):
|
||||||
|
# 1. 查询该文件已有的题目题干
|
||||||
|
existing_stems = db.query("""
|
||||||
|
SELECT JSON_EXTRACT(content, '$.stem')
|
||||||
|
FROM questions
|
||||||
|
WHERE source_file = ?
|
||||||
|
""", [file_path])
|
||||||
|
|
||||||
|
# 2. 调用出题接口,传入已有题干
|
||||||
|
response = requests.post('http://rag-service:5001/exam/generate', json={
|
||||||
|
'file_path': file_path,
|
||||||
|
'collection': collection,
|
||||||
|
'question_types': question_types,
|
||||||
|
'exclude_stems': [row[0] for row in existing_stems]
|
||||||
|
})
|
||||||
|
|
||||||
|
return response.json()
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 四、新增字段(可选消费)
|
||||||
|
|
||||||
|
### 4.1 出题结果新增字段
|
||||||
|
|
||||||
|
`POST /exam/generate` 和 `POST /exam/generate-smart` 的 `data` 对象新增三个字段:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"data": {
|
||||||
|
"questions": [...],
|
||||||
|
"total": 8,
|
||||||
|
"requested_types": {"single_choice": 5, "true_false": 3, "fill_blank": 2},
|
||||||
|
"actual_types": {"single_choice": 5, "true_false": 3, "fill_blank": 0},
|
||||||
|
"warnings": ["fill_blank: 请求 2 道,实际生成 0 道"],
|
||||||
|
...
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
| 字段 | 类型 | 说明 |
|
||||||
|
|------|------|------|
|
||||||
|
| `requested_types` | object | 后端请求的题型和数量(原样回传) |
|
||||||
|
| `actual_types` | object | 实际生成的题型和数量 |
|
||||||
|
| `warnings` | string[] | 短缺提示数组,全部生成成功时为空数组 |
|
||||||
|
|
||||||
|
**后端建议**:检查 `warnings` 是否为空,不为空时可提示用户"部分题型生成不足",或自动补发请求。
|
||||||
|
|
||||||
|
### 4.2 主观题评分警告
|
||||||
|
|
||||||
|
当主观题的 `content` 中缺少 `data.scoring_points` 评分标准时,批卷结果会在 `details.warnings` 中给出提示:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"question_id": "q5",
|
||||||
|
"score": 7.0,
|
||||||
|
"max_score": 10.0,
|
||||||
|
"grading_status": "success",
|
||||||
|
"details": {
|
||||||
|
"scoring_breakdown": [...],
|
||||||
|
"overall_feedback": "...",
|
||||||
|
"warnings": ["缺少评分标准(scoring_points),评分结果仅供参考"]
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
此时 `grading_status` 仍为 `"success"`,但评分准确度可能受影响。后端可在前端展示时附上"评分仅供参考"的提示。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 五、完整的出题→入库→批卷数据流(更新后)
|
||||||
|
|
||||||
|
```
|
||||||
|
┌──────────────────────────────────────────────────────────────────────────┐
|
||||||
|
│ 后端完整流程 │
|
||||||
|
│ │
|
||||||
|
│ 1. 调用出题接口 │
|
||||||
|
│ POST /exam/generate │
|
||||||
|
│ → 首次出题:不传 exclude_stems │
|
||||||
|
│ → 追加出题:查询已有题干,传入 exclude_stems 避免重复 │
|
||||||
|
│ → 返回 questions[],每题包含 question_type, content, source_trace │
|
||||||
|
│ → 检查 warnings 是否有短缺提示 │
|
||||||
|
│ │
|
||||||
|
│ 2. 审核入库(后端自行决定) │
|
||||||
|
│ → 可删除/修改不满意的题目 │
|
||||||
|
│ → 存入数据库时保留 content 字段原样 │
|
||||||
|
│ → 生成 question_id (UUID),设置 max_score │
|
||||||
|
│ │
|
||||||
|
│ 3. 学生作答 │
|
||||||
|
│ → 收集 student_answer │
|
||||||
|
│ │
|
||||||
|
│ 4. 调用批卷接口 │
|
||||||
|
│ POST /exam/grade │
|
||||||
|
│ → content 直接从数据库取出透传(与出题接口返回的结构一致) │
|
||||||
|
│ → 检查 grading_status 判断每题是否评分成功 │
|
||||||
|
│ → grading_status=failed 的题目可标记待重批 │
|
||||||
|
│ │
|
||||||
|
│ 5. 更新成绩 │
|
||||||
|
│ → 根据 question_id 匹配结果,写入学生成绩表 │
|
||||||
|
└──────────────────────────────────────────────────────────────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
**关键要点**:出题返回的 `content` 和批卷接收的 `content` 结构完全一致,后端只需原样存取即可,无需任何字段转换。
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 六、后端修改清单
|
||||||
|
|
||||||
|
| 序号 | 修改项 | 紧急程度 | 说明 |
|
||||||
|
|------|--------|----------|------|
|
||||||
|
| 1 | 批卷请求 `question_content` 改为 `content` | **必须** | 否则批卷接口无法读取题目内容,所有评分失败 |
|
||||||
|
| 2 | 批卷结果解析改用 `grading_status` + `details` | **必须** | 否则无法正确获取评分详情 |
|
||||||
|
| 3 | 处理 `grading_status: "failed"` 情况 | **建议** | 避免将 LLM 异常导致的 0 分直接记入成绩 |
|
||||||
|
| 4 | **追加出题时传入 `exclude_stems`** | **强烈建议** | 避免同一文件多次出题产生重复题目 |
|
||||||
|
| 5 | 出题请求总题数控制在 20 以内 | **建议** | 否则返回 400 错误 |
|
||||||
|
| 6 | 前端校验 question_types 和 difficulty | **建议** | 减少无效请求 |
|
||||||
|
| 7 | 消费 `warnings` 字段做短缺提示 | 可选 | 提升用户体验 |
|
||||||
|
| 8 | 消费主观题 `details.warnings` | 可选 | 提示评分可信度 |
