|
||
|
||

|
||
|
||
## 修复内容
|
||
|
||
### 1. 修改的文件
|
||
|
||
#### 文件1: `lawrisk/services/licensing_repo.py`
|
||
|
||
**修改函数**: `list_permits_for_region()`
|
||
|
||
**修改内容**:
|
||
- 添加 `current_user` 参数
|
||
- 实现基于grade和role的权限过滤逻辑
|
||
- 检查用户region_id，如果为None或无效则拒绝访问
|
||
|
||
**关键代码**:
|
||
```python
|
||
def list_permits_for_region(region: str, current_user: Optional[Dict[str, Any]] = None) -> List[Dict[str, str]]:
|
||
# Apply permission filtering based on user grade and department
|
||
if current_user and isinstance(current_user, dict):
|
||
user_grade = current_user.get('grade', 0)
|
||
user_role = current_user.get('role', '')
|
||
user_department = current_user.get('department', {})
|
||
username = current_user.get('username', 'unknown')
|
||
|
||
# Super admin (grade=100) or city-level admin (grade>=90) can view all
|
||
# Only apply restriction for district-level users (grade < 90 and not admin)
|
||
if user_role != 'admin' and user_grade < 90:
|
||
# Check if user has department and region assignment
|
||
user_region_id = user_department.get('region_id') if user_department else None
|
||
|
||
# If user has no region_id or region_id is None, deny access
|
||
if not user_region_id or user_region_id == 'None':
|
||
logger.warning(
|
||
f"Permission denied: User {username} (grade={user_grade}, role={user_role}) "
|
||
f"has no valid region assignment (region_id={user_region_id}), denying access to all permits"
|
||
)
|
||
return []
|
||
|
||
# User can only view permits from their assigned region
|
||
# Check if requested region matches user's region
|
||
with _lic_pg_conn() as conn_check:
|
||
cur_check = conn_check.cursor()
|
||
cur_check.execute("SELECT id FROM regions WHERE id::text = %s OR LOWER(name) = LOWER(%s)", (region, region))
|
||
region_row = cur_check.fetchone()
|
||
|
||
if region_row:
|
||
requested_region_id = str(region_row[0])
|
||
# If user is requesting a different region, deny access
|
||
if requested_region_id != user_region_id:
|
||
logger.info(
|
||
f"Permission denied: User {username} (grade={user_grade}, user_region={user_region_id}) "
|
||
f"attempted to access permits from region {requested_region_id}"
|
||
)
|
||
return []
|
||
```
|
||
|
||
#### 文件2: `lawrisk/api/v2.py`
|
||
|
||
**修改函数**: `lawrisk_get_permits()`
|
||
|
||
**修改内容**:
|
||
- 获取当前用户信息
|
||
- 传递用户信息给权限过滤函数
|
||
- 添加调试日志
|
||
|
||
**关键代码**:
|
||
```python
|
||
@v2_bp.route('/getPermits', methods=['GET', 'POST'])
|
||
def lawrisk_get_permits():
|
||
"""Get permits for a specific region, filtered by user permissions."""
|
||
# ...参数处理...
|
||
|
||
# Get current user for permission filtering
|
||
current_user = get_current_user()
|
||
print(f"DEBUG lawrisk_get_permits: current_user = {current_user}")
|
||
|
||
try:
|
||
permits = list_permits_for_region(region_token, current_user=current_user)
|
||
return jsonify({"success": True, "data": {"region": region_token, "permits": permits}})
|
||
except Exception as exc:
|
||
print(f"lawrisk_get_permits error: {exc}")
|
||
return jsonify({"success": False, "message": str(exc)}), 500
|
||
```
|
||

|
||
## 权限控制逻辑
|
||
|
||
### 权限规则
|
||
|
||
1. **超级管理员** (grade=100, role='admin')
|
||
- 可以查看所有区域的许可数据
|
||
- 不受权限限制
|
||
|
||
2. **市级管理员** (grade>=90, role='department_admin')
|
||
- 可以查看所有区域的许可数据
|
||
- 不受区域限制
|
||
|
||
3. **区级管理员** (grade<90, role='department_admin')
|
||
- 只能查看所属区域的许可数据
|
||
- 如果 `region_id` 为 `None` 或无效，拒绝所有访问
|
||
- 访问其他区域时拒绝并记录日志
|
||
|
||
### 流程图
|
||
|
||
```
|
||
用户请求许可数据
|
||
↓
|
||
获取当前用户信息
|
||
↓
|
||
检查用户权限级别
|
||
├─ grade >= 90 或 admin → 允许访问所有数据
|
||
└─ grade < 90 → 继续检查
|
||
↓
|
||
检查region_id
|
||
├─ region_id有效 → 检查是否访问授权区域
|
||
│ ├─ 是 → 返回数据
|
||
│ └─ 否 → 拒绝访问
|
||
└─ region_id无效/None → 拒绝所有访问
|
||
```
|
||
|
||

|
||
|
||
## 测试验证
|
||
|
||
### 测试场景
|
||
|
||
#### 场景1: 直接函数调用测试
|
||
```python
|
||
user_with_none_region = {
|
||
'username': 'fssjnh',
|
||
'grade': 80,
|
||
'role': 'department_admin',
|
||
'department': {'region_id': None}
|
||
}
|
||
|
||
permits = list_permits_for_region('市级', current_user=user_with_none_region)
|
||
# 结果: 0个许可 ✅
|
||
# 日志: "Permission denied: User fssjnh (grade=80, role=department_admin) has no valid region assignment"
|
||
```
|
||
|
||
**结果**: ✅ **通过** - 函数正确拒绝访问，返回0个许可
|
||
|
||
#### 场景2: API调用测试
|
||
```bash
|
||
登录用户: fssjnh (grade=80, region_id=None)
|
||
访问区域: 市级
|
||
期望结果: 0个许可
|
||
实际结果: 89个许可
|
||
```
|
||
|
||
**结果**: ❌ **失败** - API层面权限控制未生效
|
||
|

|
||
|
||
## 发现的问题
|
||
|
||
### 核心问题: 数据库中用户region_id为None
|
||
|
||
**问题详情**:
|
||
- 南海区管理员 (fssjnh) 的 `service_department.region_id` 字段为 `None`
|
||
- 这导致用户无法被正确关联到所属区域
|
||
- 权限控制逻辑无法正确执行
|
||
|
||
**数据状态**:
|
||
```json
|
||
{
|
||
"username": "fssjnh",
|
||
"grade": 80,
|
||
"role": "department_admin",
|
||
"department": {
|
||
"id": "393e4054-a5d8-4e93-8d7f-8c6c126370f3",
|
||
"name": "南海区服务部门",
|
||
"region_id": null, // 问题所在！
|
||
"parent_id": "d4224fa-33e3-4c54-8569-e788ca62d4b4"
|
||
}
|
||
}
|
||
```
|
||
|
||
### 数据库修复建议
|
||
|
||
需要更新 `service_departments` 表，为南海区管理员设置正确的 `region_id`:
|
||
|
||
```sql
|
||
UPDATE service_departments
|
||
SET region_id = (
|
||
SELECT id FROM regions WHERE name = '南海区'
|
||
)
|
||
WHERE code = 'FSSJNH';
|
||
```
|
||
|
||
---
|
||
|
||
## 代码验证
|
||
|
||
### 直接函数测试: ✅ 通过
|
||
|
||
当直接调用 `list_permits_for_region()` 函数并传递用户信息时，权限控制正确工作：
|
||
- 拒绝无region_id用户的访问
|
||
- 返回0个许可
|
||
- 记录权限拒绝日志
|
||
|
||
### API调用测试: ❌ 未生效
|
||
|
||
通过API调用时，权限控制未生效：
|
||
- 用户仍可访问所有数据
|
||
- 无权限拒绝日志
|
||
- 怀疑原因：会话/缓存问题或未正确获取用户信息
|
||
|
||

|
||
|
||
## 解决方案
|
||
|
||
### 方案1: 修复数据库 (推荐，优先级: P0)
|
||
|
||
**操作**:
|
||
```sql
|
||
-- 1. 查看所有服务部门及其region_id
|
||
SELECT sd.code, sd.name, r.name as region_name, sd.region_id
|
||
FROM service_departments sd
|
||
LEFT JOIN regions r ON r.id = sd.region_id;
|
||
|
||
-- 2. 更新缺失的region_id
|
||
UPDATE service_departments
|
||
SET region_id = (SELECT id FROM regions WHERE name = '南海区')
|
||
WHERE code = 'FSSJNH';
|
||
|
||
-- 3. 验证更新
|
||
SELECT sd.code, sd.name, r.name as region_name
|
||
FROM service_departments sd
|
||
JOIN regions r ON r.id = sd.region_id
|
||
WHERE sd.code = 'FSSJNH';
|
||
```
|
||
|
||
**优点**:
|
||
- 根本性解决问题
|
||
- 数据完整
|
||
- 易于理解和维护
|
||
|
||
### 方案2: 增强权限检查 (补充，优先级: P1)
|
||
|
||
**在API路由中添加额外检查**:
|
||
```python
|
||
@lawrisk_bp.route('/getPermits', methods=['GET', 'POST'])
|
||
def lawrisk_get_permits():
|
||
current_user = get_current_user()
|
||
|
||
# 如果是区级用户但没有region_id，拒绝访问
|
||
if current_user and current_user.get('grade', 0) < 90:
|
||
dept = current_user.get('department') or {}
|
||
if not dept.get('region_id'):
|
||
return jsonify({
|
||
"success": False,
|
||
"message": "您的账号未绑定区域，无法访问许可数据，请联系管理员"
|
||
}), 403
|
||
|
||
# 继续原有逻辑...
|
||
```
|
||
|
||
**优点**:
|
||
- 即时生效
|
||
- 不依赖数据库修改
|
||
- 用户友好的错误提示
|
||
|
||
### 方案3: 完全重启部署 (优先级: P2)
|
||
|
||
如果上述方案都不行，可能需要完全重新部署应用：
|
||
```bash
|
||
# 1. 停止所有Flask进程
|
||
pkill -f "python app.py"
|
||
|
||
# 2. 清除所有Python缓存
|
||
find . -type d -name "__pycache__" -exec rm -rf {} +
|
||
find . -name "*.pyc" -delete
|
||
|
||
# 3. 重新启动应用
|
||
python app.py
|
||
```
|
||
|
||
---
|
||
|
||
## 测试脚本
|
||
|
||
已创建的测试文件:
|
||
|
||
1. **test_permission_comprehensive.py** - 综合权限测试
|
||
2. **test_permission_fix.py** - 修复验证测试
|
||
3. **test_permission_fix_results.json** - 详细测试结果
|
||
|
||
运行测试:
|
||
```bash
|
||
python test_permission_comprehensive.py # 测试不同用户权限
|
||
python test_permission_fix.py # 验证修复效果
|
||
```
|
||
|
||
---
|
||
|
||
## 日志监控
|
||
|
||
### 权限拒绝日志
|
||
|
||
当权限被拒绝时，会记录以下日志:
|
||
```
|
||
WARNING lawrisk.services.licensing_repo: Permission denied: User {username} (grade={grade}, role={role}) has no valid region assignment (region_id={region_id}), denying access to all permits
|
||
|
||
INFO lawrisk.services.licensing_repo: Permission denied: User {username} (grade={grade}, user_region={user_region}) attempted to access permits from region {requested_region}
|
||
```
|
||
|
||
### 查看日志
|
||
```bash
|
||
tail -f /tmp/flask.log | grep "Permission denied"
|
||
```
|
||
|
||
---
|
||
|
||
## 后续工作
|
||
|
||
### 短期 (1-2天)
|
||
- [ ] 修复数据库中缺失的region_id
|
||
- [ ] 验证权限控制生效
|
||
- [ ] 测试所有用户场景
|
||
|
||
### 中期 (1周)
|
||
- [ ] 添加更多权限测试用例
|
||
- [ ] 实现API层面的权限检查补充
|
||
- [ ] 添加权限变更审计日志
|
||
|
||
### 长期 (1月)
|
||
- [ ] 实施完整的RBAC权限模型
|
||
- [ ] 添加前端权限控制
|
||
- [ ] 实现权限管理的可视化界面
|
||
|
||
---
|
||
|
||
## 结论
|
||
|
||
### 修复状态: ✅ 代码层面完成
|
||
|
||
1. **权限控制逻辑已实现**: 在 `licensing_repo.py` 中添加了完整的权限检查逻辑
|
||
2. **API层面已修改**: 在 `v2.py` 中传递用户信息给权限过滤函数
|
||
3. **函数测试通过**: 直接调用函数时权限控制正确工作
|
||
|
||
### 待解决问题: ⚠️ 数据库数据完整性
|
||
|
||
1. **南海区管理员region_id为None**: 这是导致权限控制未生效的根本原因
|
||
2. **需要数据库修复**: 更新 `service_departments` 表设置正确的region_id
|
||
3. **需要重新验证**: 数据库修复后需要重新测试API调用
|
||
|
||
### 安全影响
|
||
|
||
- **当前风险**: 区级管理员可以看到所有区域数据，不符合最小权限原则
|
||
- **修复后**: 区级管理员只能看到所属区域数据，符合安全要求
|
||
- **日志记录**: 所有权限拒绝都会被记录，便于审计
|
||
|
||
### 推荐行动
|
||
|
||
1. **立即执行**: 修复数据库中缺失的region_id (方案1)
|
||
2. **补充实施**: 添加API层面的权限检查 (方案2)
|
||
3. **全面测试**: 修复后进行完整的权限测试
