refactor: 架构重组 — doc/bot → core/infra，新增 Agent 调度模块
- src/doc/ 拆分为 src/core/extraction/, matching/, validation/（核心业务逻辑） - src/bot/ 重命名为 src/infra/browser/（浏览器自动化基础设施） - fill_consumable_doc.py → src/infra/documents/consumable.py - 新增 Agent 调度模块：coordinator.py, events.py, session.py，重构 orchestrator.py - 更新 AGENTS.md、README.md 及所有子目录 README

|
**关键约束**：
|
||||||
|
- `infra` 不依赖 `core` 和 `agent`，只提供工具能力
|
||||||
|
- `core` 零外部依赖，不依赖 Flask、Playwright 等框架
|
||||||
|
- `agent` 依赖 `core` 和 `infra`，作为调度中枢编排各模块
|
||||||
|
- 所有跨层调用均通过 `__init__.py` 导出的稳定接口
|
||||||

|
||||||
|
|
||||||
|
## 三、CLI 模式数据流
|
||||||
|
|
||||||
|
```mermaid
|
||||||
|
graph TD
|
||||||
|
CLI_ENTRY["main.py --step all"] --> PIPE["pipeline.py run_pipeline()"]
|
||||||
|
|
||||||

|
||||||
|
end
|
||||||
|
|
||||||
|
subgraph Step2["Step 2: 信息提取"]
|

|
SAVE --> TYPE{"判断报销类型"}
|
||||||
|

|
||||||
|
BOT -->|普通| BOT_N["browser/normal.py"]
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
**关键文件输出**：
|
||||||
|
|
||||||
|
| 文件 | 来源 | 说明 |
|
||||||
|
|------|------|------|
|
||||||
|
| `payment_records.csv` | Step 1 | 支付记录级别（每笔刷卡记录一行） |

|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 四、Web 模式数据流
|
||||||
|
|
||||||
|
```mermaid
|
||||||
|
sequenceDiagram
|
||||||
|
participant F as 前端 (浏览器)
|
||||||
|
participant API as routes.py
|
||||||
|
participant PW as pipeline_web.py
|
||||||
|
participant AG as agent/orchestrator.py
|
||||||
|
participant EX as core/extraction/
|
||||||
|
participant VA as core/validation/
|
||||||
|
participant SSE as SSE 轮询
|
||||||
|
|
||||||
|
F->>API: POST /api/session → 创建 session
|
||||||
|
F->>API: POST /api/upload/:sid → 上传文件
|
||||||
|
F->>API: POST /api/agent/process/:sid
|
||||||
|
API-->>F: {status: "started"}
|
||||||
|
F->>SSE: GET /api/logs/:sid (SSE 长连接)
|
||||||
|
|
||||||
|
Note over API: 后台 daemon 线程启动
|
||||||
|
|
||||||
|
API->>PW: extract_invoices(session_dir)
|
||||||
|
PW->>EX: 发票提取 + 分类 + 匹配
|
||||||
|
EX-->>PW: payment_records, applications, groups
|
||||||
|
|
||||||
|
API->>AG: run_agent_round(session_dir, session)
|
||||||
|
loop 校验-修正循环 (最多 3 次)
|
||||||
|
AG->>EX: llm_query_text() 提取信息
|
||||||
|
AG->>VA: validate_extracted_info() 规则校验
|
||||||
|
alt 校验失败
|
||||||
|
AG->>AG: 构建修正提示
|
||||||
|
end
|
||||||
|
end
|
||||||
|
AG-->>API: session (READY 或 AWAITING_SUPPLEMENT)
|
||||||
|
|
||||||
|
SSE-->>F: file_progress, llm_stream, agent_state_change, agent_ready/agent_request_supplement
|
||||||
|
|
||||||
|
API->>API: 写入 result.json
|
||||||
|
SSE-->>F: done (携带 result)
|
||||||
|
F->>F: 关闭 SSE, 展示结果
|
||||||
|
```
|
||||||
|
|
||||||
|
### Web 模式特有的 Agent 调度
|
||||||
|
|
||||||
|
CLI 模式中 `pipeline.py` 直接调用 `extract_invoices()` → `infra/browser/`，不经过 Agent 层。
|
||||||
|
|
||||||
|
Web 模式中 `routes.py` 启动后台线程，调用 `agent/orchestrator.py` 作为调度中枢：
|
||||||
|
|
||||||
|
```
|
||||||
|
run_agent_round()
|
||||||
|
├── 1. load_cache() — 检查缓存
|
||||||
|
├── 2. _do_extraction_with_validation() — 提取-校验-修正循环
|
||||||
|
│ ├── llm_query_text() — LLM 提取结构化信息
|
||||||
|
│ ├── validate_extracted_info() — 规则校验
|
||||||
|
│ └── 校验失败 → 构建修正提示 → 再次调用 LLM (最多 3 次)
|
||||||
|
├── 3. 判断 can_submit 字段
|
||||||
|
│ ├── true → READY → 自动触发财务提交
|
||||||
|
│ └── false → AWAITING_SUPPLEMENT → 等待用户补充
|
||||||
|
├── 4. 用户补充处理
|
||||||
|
│ ├── add_supplement() — 记录补充文件
|
||||||
|
│ └── process_user_text_supplement() — LLM 解析文字补充
|
||||||
|
└── 5. save_agent_state() — 持久化状态
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 五、Agent 状态机
|
||||||
|
|
||||||
|
```mermaid
|
||||||
|
stateDiagram-v2
|
||||||
|
[*] --> IDLE: 会话创建
|
||||||
|
|
||||||
|
IDLE --> EXTRACTING: POST /api/agent/process
|
||||||
|
IDLE --> EXTRACTING: POST /api/agent/supplement
|
||||||
|
IDLE --> EXTRACTING: POST /api/agent/user-supplement
|
||||||
|
|
||||||
|
EXTRACTING --> READY: can_submit == true
|
||||||
|
EXTRACTING --> AWAITING_SUPPLEMENT: can_submit == false
|
||||||
|
EXTRACTING --> ERROR: 异常 / 轮次超限
|
||||||
|
|
||||||
|
READY --> SUBMITTING: _emit_ready_and_submit()
|
||||||
|
SUBMITTING --> DONE: 财务提交完成
|
||||||
|
|
||||||
|
AWAITING_SUPPLEMENT --> EXTRACTING: 用户补充文件/文字
|
||||||
|
AWAITING_SUPPLEMENT --> READY: 用户强制提交
|
||||||
|
|
||||||
|
note right of EXTRACTING
|
||||||
|
LLM 提取 + validator 校验
|
||||||
|
最多 3 次重试
|
||||||
|
end note
|
||||||
|
```
|
||||||
|
|
||||||
|
### 终态保护
|
||||||
|
|
||||||
|
以下状态为终态，再次触发 `run_agent_round()` 会被跳过：
|
||||||
|
- `DONE` — 提交完成
|
||||||
|
- `SUBMITTING` — 提交中
|
||||||
|
- `READY` — 准备提交
|
||||||
|
|
||||||
|
### 轮次保护
|
||||||
|
|
||||||
|
默认最多 5 轮（`AgentSession.max_rounds`），超限后进入 `ERROR` 状态，用户可选择强制提交。
|
||||||
|
|

## 六、SSE 事件通信机制
|
||||||
|
|
||||||
|
```mermaid
|
||||||
|
graph LR
|
||||||
|
subgraph 后端写入
|
||||||
|

|
||||||
|
LLM[LLM 回调] -->|追加写入| LS[llm_stream.log]
|
||||||
|
PW[pipeline_web.py] -->|追加写入| FE[file_events.log]
|
||||||
|
SH[sse_handler.py] -->|追加写入| SL[session.log]
|
||||||
|

end
|
||||||
|
|
||||||
|
subgraph SSE 轮询 (0.5s)
|
||||||
|

|
end
|
||||||
|
|
||||||
|
POLL -->|event: agent_*| FRONT[前端 agent.js]
|
||||||
|
POLL -->|event: llm_stream| FRONT
|
||||||
|
POLL -->|event: file_progress| FRONT
|
||||||
|
POLL -->|event: done| FRONT
|
||||||
|
```
|
||||||
|
|
||||||
|
### 信号文件生命周期
|
||||||
|
|
||||||
|
| 阶段 | `result.json` | `llm_stream.log` | `agent_events.log` | `file_events.log` | `session.log` |
|
||||||

## 七、发票类型路由
|
||||||
|
|
||||||
|
```mermaid
|
||||||
|
graph TD
|
||||||
|
INPUT["上传文件 (PDF/图片)"] --> EXT["LLM 多模态识别"]
|
||||||
|
EXT --> TYPE{"invoice_type?"}
|
||||||
|
|
||||||
|
TYPE -->|train| TRAVEL["差旅报销流程"]
|
||||||
|
TYPE -->|hotel| TRAVEL
|
||||||
|
TYPE -->|general| NORMAL["普通报销流程"]
|
||||||
|

|
NORMAL --> NORMAL_INFO["提取普通发票信息<br/>normal_info.json"]
|
||||||
|
NORMAL_INFO --> NORMAL_BOT["browser/normal.py<br/>填报普通报销单"]
|
||||||
|
NORMAL_INFO --> CONSUMABLE["生成易耗品出库单<br/>(仅普通报销)"]
|
||||||
|
|
||||||
|
MATCH --> MERGE["合并到对应发票组"]
|
||||||
|
|
||||||
|

|
style MATCH fill:#d1e7dd,stroke:#198754
|
||||||
|
style APP fill:#fff3cd,stroke:#ffc107
|
||||||
|
```
|
||||||
|
|
||||||
|
| 发票类型 | `invoice_type` | 报销流程 | 生成出库单 |
|
||||||
|
|----------|---------------|---------|:--:|
|
||||||
|
| 高铁票/火车票 | `train` | 差旅报销 | 否 |
|
||||||
|
| 酒店住宿 | `hotel` | 差旅报销 | 否 |
|
||||||
|
| 普通发票 | `general` | 普通报销 | 是 |
|
||||||
|
| 支付记录 | `payment` | 参与匹配 | 否 |
|
||||||
|
| 出差申请单 | `application` | 单独存储 | 否 |
|
||||||
|
|
||||||
|
> 差旅发票和普通发票不支持混报，混合时系统按普通报销处理。

| **Agent 是调度中枢** | 校验-修正循环由 Agent 编排，不内嵌在 `llm_extractor` 中 |
|
||||||
|
| **模块职责单一** | `llm_extractor` 只管提取，`validator` 只管校验，Agent 负责编排 |
|
||||||
|
| **core 零外部依赖** | 不依赖 Flask、Playwright 等框架 |
|
||||||
|
| **infra 不依赖业务** | 基础设施层只提供工具能力，不包含业务逻辑 |
|
||||||
|
| **缓存优先** | 信息提取优先读取 `.invoice_cache`，避免重复调用 LLM |
|
||||||
|
| **轮次保护** | 默认 5 轮上限，校验-修正循环最多重试 3 次 |
|
||||||
|
| **终态保护** | `DONE`/`SUBMITTING`/`READY` 状态下不再重复处理 |
|
||||||
|
| **容错降级** | 规则校验 3 次重试后返回最佳结果，不阻断流程 |
|
||||||
|
| **原子写入** | 状态文件先写 `.tmp` 再 `rename()`，防止读取不完整数据 |

## 二、问题分析
|
||||||
|
|
||||||
|
### 2.1 职责不清（高耦合）
|
||||||
|
|
||||||
|
| 问题 | 位置 | 说明 |
|
||||||
|
|------|------|------|
|
||||||
|
| **doc 模块职责过重** | `src/doc/` | 同时负责：提取、匹配、校验、提示词、PDF渲染、出库单填写、CSV操作 |
|
||||||
|
| **Web 层重复逻辑** | `pipeline_web.py` vs `pipeline_core.py` | 两者的 `is_travel_invoice`、`extract_and_cache_*` 逻辑重复 |
|
||||||
|
| **提示词与校验耦合** | `validator.py` | 校验规则直接引用提示词相关函数，缺乏分层 |
|
||||||
|
| **bot 模块位置** | `src/bot/` | 浏览器自动化属于基础设施，却被放在 src 根目录而非独立模块 |
|
||||||
|
|
||||||
|
### 2.2 逻辑混乱
|
||||||
|
|
||||||
|
1. **`src/doc/validator.py`** 的问题：
|
||||||
|
- 校验规则（`TRAVEL_VALIDATION_RULES`）硬编码在模块中，修改需改代码
|
||||||
|
- `FieldRule` 和 `ArrayRule` 类与校验逻辑紧耦合
|
||||||
|
- 数组元素字段支持简单格式和详细格式两种配置，增加了理解成本
|
||||||
|
|
||||||
|
2. **`src/doc/prompt.py`** 的问题：
|
||||||
|
- 简单的文件读取包装，但调用方分散
|
||||||
|
- `build_invoice_system_prompt()` 和 `build_travel_info_system_prompt()` 分别调用，但结构相似
|
||||||
|
|
||||||
|
3. **`src/agent/orchestrator.py`** 的问题：
|
||||||
|
- 校验循环与提取逻辑混合在 `_do_extraction_with_validation`
|
||||||
|
- SSE 事件发射逻辑（`_emit_agent_event`）与业务逻辑混杂
|
||||||
|
- 状态机转换逻辑分散
|
||||||
|
|
||||||
|
### 2.3 分层不合理
|
||||||
|
|
||||||
|
```
|
||||||
|
当前分层（按目录）:
|
||||||
|
main.py → pipeline.py → doc/ + bot/
|
||||||
|
↓
|
||||||
|
pipeline_web.py → web/
|
||||||
|
|
||||||
|
建议分层（按职责）:
|
||||||
|
应用层: main.py, pipeline.py, pipeline_web.py
|
||||||
|
业务层: agent/orchestrator.py, doc/validator.py, doc/matcher.py
|
||||||
|
提取层: doc/extractor.py, doc/llm_extractor.py
|
||||||
|
基础设施层: bot/, web/, doc/pdf.py, doc/fill_consumable_doc.py
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||

|
||||||

## 三、重构建议

||||||
|

|
||||||
|
└── cache.py
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.2 关键重构点
|
||||||
|
|
||||||
|
#### 3.2.1 doc 模块拆分
|
||||||
|
|
||||||
|
| 职责 | 建议移动位置 |
|
||||||
|
|------|-------------|
|
||||||
|
| `validator.py` | `core/validation/` |
|
||||||
|
| `matcher.py` | `core/matching/` |
|
||||||
|
| `llm_extractor.py` | `core/extraction/` |
|
||||||
|
| `extractor.py` | `core/extraction/` |
|
||||||
|
| `invoice.py` | `infra/documents/` |
|
||||||
|
| `pdf.py` | `infra/documents/` |
|
||||||
|
| `fill_consumable_doc.py` | `infra/documents/` |
|
||||||
|
| `prompt.py` + `prompts/` | `infra/llm/` |
|
||||||
|
|
||||||
|
#### 3.2.2 消除重复逻辑
|
||||||
|
|
||||||
|
**问题**: `pipeline_web.py` 和 `pipeline_core.py` 都有相似逻辑：
|
||||||
|
- `is_travel_invoice()`
|
||||||
|
- `extract_and_cache_travel_info()`
|
||||||
|
- `extract_and_cache_normal_info()`
|
||||||
|
|
||||||
|
**建议**: 将这些公共逻辑统一到 `core/pipeline/` 目录，两个入口调用同一模块。
|
||||||
|
|
||||||
|
#### 3.2.3 Validator 重构
|
||||||
|
|
||||||
|
**当前问题**:
|
||||||
|
- 校验规则硬编码
|
||||||
|
- `FieldRule` 和 `ArrayRule` 类过于复杂
|
||||||
|
|
||||||
|
**建议**:
|
||||||
|
- 将校验规则外部化为 JSON/YAML 配置文件
|
||||||
|
- 简化 `FieldRule` 为单一数据结构
|
||||||
|
- 统一顶层字段和数组元素字段的校验方式
|
||||||
|
|
||||||
|
#### 3.2.4 Agent 拆分
|
||||||
|
|
||||||
|
**当前问题**:
|
||||||
|
- `orchestrator.py` 包含：状态机、SSE 事件、校验循环、提取逻辑
|
||||||
|
|
||||||
|
**建议**:
|
||||||
|
```
|
||||||
|
agent/
|
||||||
|
├── session.py # 状态机定义 + 会话数据模型
|
||||||
|
├── coordinator.py # 校验-修正循环
|
||||||
|
├── events.py # SSE 事件发射
|
||||||
|
└── orchestrator.py # 总调度入口
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.3 接口契约强化
|
||||||
|
|
||||||
|
| 模块 | 依赖关系 | 接口契约 |
|
||||||
|
|------|----------|----------|
|
||||||
|
| `core/extraction` | 被 `apps/*` 调用 | 返回 `(payment_records, applications, groups)` |
|
||||||
|
| `core/validation` | 被 `agent/*` 调用 | `validate(info, rules) -> ValidationReport` |
|
||||||
|
| `core/matching` | 被 `extraction` 调用 | `match(invoices, cards) -> List[Dict]` |
|
||||||
|
| `infra/browser` | 被 `apps/*` 调用 | `run(bot, info) -> None` |
|
||||||
|
| `infra/llm` | 被 `core/extraction` 调用 | `extract_document(file) -> dict` |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 四、优先重构顺序
|
||||||
|
|
||||||
|
### 第一阶段（降低耦合）
|
||||||
|
1. 将 `doc/` 拆分为 `core/` + `infra/`
|
||||||
|
2. 消除 `pipeline_web.py` 和 `pipeline_core.py` 的重复逻辑
|
||||||
|
3. 将 `bot/` 移动到 `infra/browser/`
|
||||||
|
|
||||||
|
### 第二阶段（职责清晰化）
|
||||||
|
4. 拆分 `agent/orchestrator.py` 为多个模块
|
||||||
|
5. 外部化 `validator.py` 的校验规则为配置文件
|
||||||
|
6. 统一 SSE 事件处理接口
|
||||||
|
|
||||||
|
### 第三阶段（可维护性）
|
||||||
|
7. 完善 `__init__.py` 的接口导出
|
||||||
|
8. 添加模块间依赖注入机制
|
||||||
|
9. 建立跨模块调用规范
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 五、当前项目优点
|
||||||
|
|
||||||
|
1. **日志规范**: 统一的 `get_logger()` 方式，全局日志管理
|
||||||
|
2. **异常体系**: 清晰的 `ReimbursementError` 异常层次
|
||||||
|
3. **SSE 事件协议**: 良好的实时反馈机制
|
||||||
|
4. **缓存设计**: `llm_extractor.py` 的缓存加载逻辑完善
|
||||||
|
5. **声明式校验**: `validator.py` 的规则配置思路正确

|
||||||
## 项目的架构思想
|
| 操作 | Makefile (跨平台) | tasks.py (Windows) |
|
||||||
|
|------|-------------------|---------------------|
|
||||||
|
| 安装依赖 + pre-commit | `make install` | `python tasks.py install` |
|
||||||
|
| 代码检查（lint+format+typecheck+deptry） | `make check` | `python tasks.py check` |
|
||||||
|
| 运行测试（含覆盖率报告） | `make test` | `python tasks.py test` |
|
||||||
|
| 运行 CLI 全流程 | `make run` | `python tasks.py run` |
|
||||||
|
| 清理缓存和虚拟环境 | `make clean` | `python tasks.py clean` |
|
||||||
|
|
||||||
* Agent 是负责调度的中枢，负责调度各个模块
|
**注意：** `tasks.py` 中的 `check` 命令使用 `&&` 连接，Windows PowerShell 不支持 `&&`，但 `tasks.py` 内部已处理为单行字符串。
|
||||||
|
|
||||||
|
## 代码质量工具链（执行顺序）
|
||||||
|
|
||||||
|
1. **Ruff lint** — `uv run ruff check .` (select: E, F, W, I, N, UP, B; ignore: E501)
|
||||||
|
2. **Ruff format** — `uv run ruff format --check .` (line-length: 120)
|
||||||
|
3. **MyPy strict mode** — `uv run mypy src/main.py` (strict=true, warn_return_any, ignore_missing_imports)
|
||||||
|
4. **deptry** — `uv run deptry .` (检测未声明、未使用、过时依赖)
|
||||||
|
|
||||||
|
### pre-commit 钩子（仅 Ruff）
|
||||||
|
|
||||||
|
`.pre-commit-config.yaml` 配置了两个 hook：
|
||||||
|
- `ruff --fix` — lint 并自动修复
|
||||||
|
- `ruff-format` — 格式化
|
||||||
|
|
||||||
|
**注意：** MyPy 和 deptry **不在** pre-commit 中，需要手动运行 `make check`。
|
||||||
|
|
||||||
|
## 项目架构（Agent 调度模式）
|
||||||
|
|
||||||
|
核心入口：`src/agent/orchestrator.py` — Agent 是负责调度的中枢，协调以下模块：
|
||||||
|
- `extraction/extractor.py` — 文件扫描 → LLM 多模态提取 → JSON 缓存
|
||||||
|
- `matching/matcher.py` — 支付记录与发票金额匹配
|
||||||
|
- `validation/validator.py` — 声明式校验器（规则配置与引擎分离）
|
||||||
|
- `infra/browser/travel.py` / `normal.py` — 浏览器自动化填报
|
||||||
|
|
||||||
|
### 数据流关键产物
|
||||||
|
|
||||||
|
| 文件 | 生成阶段 | 作用 |
|
||||||
|
|------|---------|------|
|
||||||
|
| `.invoice_cache/*.json` | extractor 提取 | 单张发票/支付记录的结构化数据 |
|
||||||
|
| `match_result.json` | matcher 匹配 | 支付截图与发票的关联关系 |
|
||||||
|
| `travel_info.json` / `normal_info.json` | LLM 综合提取 | 差旅/普通报销所需的全部结构化数据 |
|
||||||
|
| `invoice_summary.csv` | extractor 提取 | 普通发票汇总（用于生成易耗品出库单） |
|
||||||
|
|
||||||
|
### 缓存机制
|
||||||
|
|
||||||
|
CLI 模式：`scripts/data/.invoice_cache/`
|
||||||
|
Web 模式：`src/web/uploads/<session_id>/.invoice_cache/`
|
||||||
|
|
||||||
|
缓存文件与源文件同名（如 `发票1.pdf` → `.invoice_cache/发票1.json`），后续步骤均从缓存读取。删除缓存后下次处理会重新提取。
|
||||||
|
|
||||||
|
## 重要约束
|
||||||
|
|
||||||
|
* **Windows-only**：易耗品出库单填写依赖 Microsoft Word + COM (`pywin32`)，仅 Windows 可用
|
||||||
|
* **浏览器自动化**：使用 Playwright，填报时会打开 Chromium，请勿手动干扰
|
||||||
|
* **敏感信息**：`scripts/config.json` 含登录凭据，勿提交到公开仓库
|
||||||
|
* **发票类型区分**：差旅发票（高铁票/酒店住宿）不生成易耗品出库单，走差旅报销流程；普通发票生成出库单

## Web 服务
|
||||||
|
|
||||||
|
```bash
|
||||||
|
uv run python src/web/app.py
|
||||||
|
# 访问 http://localhost:5000
|
||||||
|
```

## 声明式校验器
|
||||||
|
|
||||||
|
`src/core/validation/validator.py` 采用**规则配置与校验引擎分离**的设计模式，支持声明式定义校验规则：
|
||||||
|
|
||||||
|
### 设计特点
|
||||||
|
|
||||||
|
| 特性 | 说明 |
|
||||||
|
|------|------|
|
||||||
|
| **声明式配置** | 校验规则以数据结构形式定义，无需编写代码 |
|
||||||
|
| **统一路径定位** | 使用 `path` 统一定位字段，如 `["basic_info", "travel_purpose"]` |
|
||||||
|
| **自定义校验函数** | 支持为字段定义自定义校验逻辑（日期格式、正数检查等） |
|
||||||
|
| **数组元素校验** | 支持校验数组字段的最小元素数量及每个元素的必填字段 |
|
||||||
|
| **向后兼容** | 支持简单格式 `["field1", "field2"]` 和详细格式 `{"path": [...], "custom_check": ...}` |
|
||||||
|
|
||||||
|
### 规则配置示例
|
||||||
|
|
||||||
|
```python
|
||||||
|
# 差旅报销校验规则
|
||||||
|
TRAVEL_VALIDATION_RULES = {
|
||||||
|
"fields": [
|
||||||
|
{"path": ["basic_info", "travel_purpose"], "description": "出差事由"},
|
||||||
|
{"path": ["basic_info", "start_date"], "custom_check": _is_valid_date},
|
||||||
|
],
|
||||||
|
"arrays": [
|
||||||
|
{
|
||||||
|
"path": ["payment_methods"],
|
||||||
|
"min_items": 1, # 至少1条支付记录
|
||||||
|
"element_fields": [
|
||||||
|
{"path": ["card_date"], "description": "刷卡日期"},
|
||||||
|
{"path": ["card_amount"], "custom_check": _is_positive_number},
|
||||||
|
],
|
||||||
|
},
|
||||||
|
],
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 校验规则类型
|
||||||
|
|
||||||
|
| 规则类型 | 用途 | 关键字段 |
|
||||||
|
|----------|------|----------|
|
||||||
|
| `fields` | 顶层单值字段校验 | `path`, `custom_check`, `check_empty` |
|
||||||
|
| `arrays` | 数组字段校验 | `path`, `min_items`, `element_fields` |
|
||||||
|
|
||||||
|
### 内置校验函数
|
||||||
|
|
||||||
|
- `_is_valid_date(value)` — 检查日期格式是否为 `YYYY-MM-DD`
|
||||||
|
- `_is_positive_number(value)` — 检查值是否为正数
|
||||||
|
|
||||||
|
### 扩展自定义校验
|
||||||
|
|
||||||
|
```python
|
||||||
|
# 定义自定义校验函数
|
||||||
|
def check_vehicle_type(value):
|
||||||
|
valid_types = ["飞机", "火车", "汽车", "打车"]
|
||||||
|
return isinstance(value, str) and value.strip() in valid_types
|
||||||
|
|
||||||
|
# 在规则中使用
|
||||||
|
{"path": ["vehicle_type"], "custom_check": check_vehicle_type}
|
||||||
|
```

# bot — 浏览器自动化填报模块
|
|
||||||
|
|
||||||
使用 Playwright 操作财务报销系统，自动完成登录、填单、上传附件等操作。
|
|
||||||
|
|

|
|
||||||
| 文件 | 说明 |
|
|
||||||
|------|------|
|
|
||||||
| `__init__.py` | 对外入口：`run_bot()` 和 `run_bot_web()`，负责类型判断和流程路由 |
|
|
||||||
| `base.py` | `BaseBot` 基类：浏览器生命周期、登录、导航、截图、日期格式化 |
|
|
||||||
| `travel.py` | 差旅报销填报流程：基本信息 → 差旅明细 → 支付方式 → 补助清单 → 附件上传 |
|
|
||||||
| `normal.py` | 普通发票报销填报流程：基本信息 → 总明细 → 支付方式 → 附件上传 |
|

||||||
|
|
||||||

||||||
|
|
||||||
```
|

||||||
run_bot(config, travel_info, normal_info)
|
|
||||||
├── 创建 BaseBot，启动浏览器，登录门户
|
|
||||||
├── travel_info 存在 → travel.run(bot, travel_info)
|
|
||||||
└── normal_info 存在 → normal.run(bot, normal_info)
|
|
||||||
```
|
|
||||||
|
|
||||||
- **`BaseBot`** 只保留公共操作（launch、login、navigate、create_new_form、close、screenshot）
|
|
||||||
- **差旅/普通流程** 作为独立函数接受 `bot: BaseBot` 参数，符合函数式编程偏好
|
|
||||||
- **`__init__.py`** 仅做路由分发，不包含具体填报逻辑
|
|
||||||
|
|
||||||
## 变更历史
|
|
||||||

# src/core — 核心业务逻辑
|
||||||
|
|
||||||
|
项目的核心业务层，负责信息提取、金额匹配和信息校验。此层不依赖 Web 框架或浏览器自动化等基础设施。
|
||||||
|
|
||||||
|
## 子模块
|
||||||
|
|
||||||
|
| 目录 | 说明 |
|
||||||
|
|------|------|
|
||||||
|
| `extraction/` | 文档信息提取：PDF/图片 → LLM 多模态识别 → 结构化数据 |
|
||||||
|
| `matching/` | 发票与支付记录按金额匹配（一对一 / 一对多） |
|
||||||
|
| `validation/` | 声明式信息完整性校验，规则从 JSON 配置文件加载 |
|
||||||
|
|
||||||
|
## 设计原则
|
||||||
|
|
||||||
|
- **零外部依赖**：不依赖 Flask、Playwright 等框架
|
||||||
|
- **接口契约**：每个子模块通过 `__init__.py` 导出稳定的对外接口
|
||||||
|
- **错误传播**：明确的异常层次，便于上层统一处理

# src/core/extraction — 信息提取
|
||||||
|
|
||||||
|
从 PDF 发票和图片中提取结构化数据，是系统数据流的起点。
|
||||||
|
|
||||||
|
## 文件
|
||||||
|
|
||||||
|
| 文件 | 职责 |
|
||||||
|
|------|------|
|
||||||
|
| `extractor.py` | 编排入口：扫描目录 → 逐文件提取 → 分类（发票/支付记录/申请单）→ 金额匹配 |
|
||||||
|
| `llm_extractor.py` | LLM 多模态提取核心：统一文档提取、差旅/普通信息提取、缓存管理、SSE 流式事件 |
|
||||||
|
|
||||||
|
## 对外接口
|
||||||
|
|
||||||
|
| 函数 | 说明 |
|
||||||
|
|------|------|
|
||||||
|
| `extract_invoices(directory)` | 统一提取入口，返回 `(payment_records, applications, groups)` |
|
||||||
|
| `extract_document(file_path)` | 从单个图片/PDF 提取信息 |
|
||||||
|
| `extract_travel_info(source_dir)` | 综合发票和匹配结果提取差旅信息 |
|
||||||
|
| `extract_normal_info(source_dir)` | 提取普通发票报销信息 |
|
||||||
|
| `load_cache(source_dir)` | 加载缓存的结构化数据 |
|
||||||
|
| `llm_query_text(...)` | 纯文本 LLM 查询（供 Agent 调度使用） |
|
||||||
|
|
||||||
|
## 缓存机制
|
||||||
|
|
||||||
|
提取结果缓存在 `.invoice_cache/` 目录中，文件名与源文件同名（`发票1.pdf` → `.invoice_cache/发票1.json`），避免重复调用 LLM。

将提取到的发票数据与支付记录（刷卡截图）按金额进行匹配。

## 匹配策略
|

|
|
||||||
|
| 场景 | 策略 |
|
||||||
|
|------|------|
|
||||||
|
| 发票数 == 支付记录数 | 一对一匹配：按金额降序配对，相对容差内即匹配 |
|
||||||
|
| 发票数 > 支付记录数 | 一对多匹配：贪心算法凑金额，相对容差 3% |
|
||||||
|
| 文件名匹配 | 最高优先级：文件名（不含后缀）一致时直接匹配 |
|
||||||
|
| 未匹配发票 | 单独列为一条支付记录，`remark` 标记为 `"unmatched"` |
|
||||||
|
|
||||||
|
## 业务约束
|
||||||
|
|
||||||
|
- 发票总金额 >= 支付总金额
|

|
- 输出以支付记录为主键的结果列表

# src/core/validation — 信息校验
|
||||||
|
|
||||||
|
对 LLM 提取的报销信息进行声明式规则校验，判断是否满足填报要求。
|
||||||
|
|
||||||
|
## 文件
|
||||||
|
|
||||||
|
| 文件 | 职责 |
|
||||||
|
|------|------|
|
||||||
|
| `validator.py` | 校验引擎：加载 JSON 规则配置 → 遍历字段/数组 → 输出校验报告 |
|
||||||
|
|
||||||
|
## 设计特点
|
||||||
|
|
||||||
|
- **规则与引擎分离**：校验规则存储在 `config/validation_rules.json`，引擎只负责执行
|
||||||
|
- **统一路径定位**：使用 `path` 列表定位嵌套字段，如 `["basic_info", "travel_purpose"]`
|
||||||
|
- **自定义校验**：支持 `custom_check` 函数（日期格式、正数检查等）
|
||||||
|
- **数组元素校验**：支持 `min_items` 最小数量 + 每个元素的必填字段
|
||||||
|
|
||||||
|
## 校验规则类型
|
||||||
|
|
||||||
|
| 类型 | 用途 | 配置项 |
|
||||||
|
|------|------|--------|
|
||||||
|
| `fields` | 顶层单值字段 | `path`, `required`, `custom_check`, `check_empty` |
|
||||||
|
| `arrays` | 数组字段 | `path`, `min_items`, `element_fields` |
|
||||||
|
|
||||||
|
## 对外接口
|
||||||
|
|
||||||
|
| 函数 | 说明 |
|
||||||
|
|------|------|
|
||||||
|
| `validate(info, invoice_type)` | 执行校验，返回 `ValidationReport` |
|
||||||
|
| `get_missing_fields(report)` | 提取缺失字段列表 |

#性格
|
|
||||||
|
|
||||||
你是财务报销信息完整性校验助手。你的任务是检查已提取的报销信息在语义上是否足够支撑完成报销系统填报。
|
|
||||||
|
|
||||||
**核心原则**：不仅要检查字段是否存在，还要判断信息在逻辑上是否自洽、是否足以完成填报。
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 输入数据说明
|
|
||||||
|
|
||||||
你会收到以下数据：
|
|
||||||
1. **已提取的报销信息**：包含基本信息、报销明细、支付方式、附件清单等
|
|
||||||
2. **发票缓存数据**：原始发票提取的结构化数据
|
|
||||||
3. **匹配结果**：发票与支付记录的关联关系
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 校验维度
|
|
||||||
|
|
||||||
### 1. 逻辑一致性检查
|
|
||||||
|
|
||||||
- 出差日期范围是否合理（结束日期不早于开始日期）
|
|
||||||
- 交通费的去程和返程日期是否在出差日期范围内
|
|
||||||
- 酒店入住/退房日期是否与出差时间匹配
|
|
||||||
- 支付金额总和是否与发票金额总和接近（允许小额差异）
|
|
||||||
- 补助天数计算是否正确
|
|
||||||
|
|
||||||
### 2. 信息充分性检查
|
|
||||||
|
|
||||||
- 是否有足够的信息填写所有报销系统必填项
|
|
||||||
- 出差事由是否明确具体（不能过于笼统）
|
|
||||||
- 人员信息是否完整（姓名、工号）
|
|
||||||
- 支付方式是否与支付记录对应
|
|
||||||
- 每张发票应该都有对应的支付记录，如果没有提醒用户补充支付记录
|
|
||||||
|
|
||||||
### 3. 潜在问题识别
|
|
||||||
|
|
||||||
- 发票日期与出差日期差异过大
|
|
||||||
- 同一笔支付对应多张发票但金额不匹配
|
|
||||||
- 缺少关键附件
|
|
||||||
- 人员信息不一致（如车票姓名与补助清单姓名不同）
|
|
||||||
|
|
||||||
---
|
|
||||||
### 4. 不需询问的问题
|
|
||||||
- 出差事前申请单和实际出差时间不一致这是正常的，因为规划是实际可以有差异
|
|
||||||
|
|
||||||
|
|
||||||
## 输出格式
|
|
||||||
|
|
||||||
严格返回以下 JSON 格式：
|
|
||||||
|
|
||||||
```json
|
|
||||||
{
|
|
||||||
"valid": true或false,
|
|
||||||
"confidence": 0.0到1.0之间的数字,
|
|
||||||
"issues": ["问题描述1", "问题描述2"],
|
|
||||||
"missing_info": ["缺失信息1", "缺失信息2"],
|
|
||||||
"suggestion": "补充建议"
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### 字段说明
|
|
||||||
|
|
||||||
| 字段 | 类型 | 说明 |
|
|
||||||
|------|------|------|
|
|
||||||
| `valid` | boolean | 信息在语义上是否足够支撑填报 |
|
|
||||||
| `confidence` | number | 置信度，1.0 表示完全确定，0.0 表示完全不确定 |
|
|
||||||
| `issues` | array | 发现的逻辑问题列表，无问题则为空数组 |
|
|
||||||
| `missing_info` | array | 语义上缺失的关键信息列表 |
|
|
||||||
| `suggestion` | string | 补充建议，说明需要用户上传什么材料 |
|
|
||||||
|
|
||||||
### 判定标准
|
|
||||||
|
|
||||||
- **valid = true**：信息完整且逻辑自洽，可以直接填报
|
|
||||||
- **valid = false**：存在信息缺失或逻辑矛盾，需要补充材料
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
## 最终输出要求
|
|
||||||
|
|
||||||
- 严格只输出 JSON 字符串
|
|
||||||
- JSON 语法必须正确
|
|
||||||
- 不要包含任何思考过程或解释文字

# src/infra — 基础设施层
|
||||||
|
|
||||||
|
提供浏览器自动化、文档处理和 LLM 接口等底层能力。此层不包含业务逻辑，只提供工具和平台能力。
|
||||||
|
|
||||||
|
## 子模块
|
||||||
|
|
||||||
|
| 目录 | 说明 |
|
||||||
|
|------|------|
|
||||||
|
| `browser/` | Playwright 驱动的财务系统自动填报 |
|
||||||
|
| `documents/` | 发票数据模型、PDF 渲染、Word 出库单填写 |
|
||||||
|
| `llm/` | LLM 提示词模板加载与管理 |
|
||||||
|
|
||||||
|
## 设计原则
|
||||||
|
|
||||||
|
- **无业务逻辑**：只提供工具能力，不包含业务流程判断
|
||||||
|
- **可替换性**：每个子模块通过 `__init__.py` 导出接口，便于替换实现
|
||||||
|
- **与 core 层解耦**：infra 不依赖 core，core 可通过接口调用 infra

# src/infra/browser — 浏览器自动化
|
||||||
|
|
||||||
|
使用 Playwright 操作财务报销系统，自动完成登录、填单、上传附件等操作。
|
||||||
|
|
||||||
|
## 文件
|
||||||
|
|
||||||
|
| 文件 | 职责 |
|
||||||
|
|------|------|
|
||||||
|
| `base.py` | `BaseBot` 基类：浏览器生命周期、登录信息门户、导航到报销系统、创建新单据、截图 |
|
||||||
|
| `travel.py` | 差旅报销填报流程：基本信息 → 差旅明细 → 支付方式 → 补助清单 → 附件上传 |
|
||||||
|
| `normal.py` | 普通报销填报流程：基本信息 → 总明细 → 支付方式 → 附件上传 |
|
||||||
|
| `__init__.py` | 入口函数：`run_bot()` / `run_bot_web()`，负责类型路由和流程调度 |
|
||||||
|
|
||||||
|
## 对外接口
|
||||||
|
|
||||||
|
| 函数 | 说明 |
|
||||||
|
|------|------|
|
||||||
|
| `run_bot(config, travel_info, normal_info)` | CLI 模式：根据传入信息判断差旅/普通报销 |
|
||||||
|
| `run_bot_web(config, work_dir)` | Web 模式：从缓存加载信息后执行填报 |
|
||||||
|
|
||||||
|
## 填报流程
|
||||||
|
|
||||||
|
### 差旅报销（travel）
|
||||||
|
1. 填写基本信息（事由、地点、日期、项目编号）
|
||||||
|
2. 添加差旅明细（交通费用逐条录入）
|
||||||
|
3. 填写支付方式（公务卡刷卡记录）
|
||||||
|
4. 填写补助清单（按天计算交通补助 + 伙食补助）
|
||||||
|
5. 上传附件（发票、申请单等）
|
||||||
|
|
||||||
|
### 普通报销（normal）
|
||||||
|
1. 填写基本信息（报销事由、金额）
|
||||||
|
2. 填写发票明细（总数、总金额）
|
||||||
|
3. 填写支付方式
|
||||||
|
4. 上传附件
|
||||||
|
|
||||||
|
## 注意事项
|
||||||
|
|
||||||
|
- 浏览器填报会启动 Chromium，请勿手动干扰自动化流程
|
||||||
|
- 调试截图保存在 `images/` 目录
|
||||||
|
- Web 模式以无头模式运行
