# 权限检查系统优化方案
## 项目概述
优化 `zhenxun_bot` 的权限检查系统,将每条消息的数据库/缓存查询次数从 **6-10次** 降低到 **1-2次**。
---
## 当前问题分析
### 现有查询流程
每条消息进入时,权限检查系统执行以下查询:
| 阶段 | 查询内容 | 次数 |
|-----|---------|------|
| `_load_context` | PluginInfo, UserConsole, GroupConsole | 3次 |
| `auth_ban` | BanConsole | 1-2次 |
| `auth_bot` | BotConsole | 1次 |
| `auth_admin` | LevelUser (全局+群组) | 1-2次 |
| `auth_limit` | PluginLimit (如果不在内存) | 0-1次 |
**总计:6-10次查询**
### 问题根源
1. 数据分散在多个表:`user_console`, `group_console`, `ban_console`, `bot_console`, `level_user`, `plugin_info`
2. 每个检查模块独立查询,缺乏数据共享
3. 即使有 Redis 缓存,也需要多次网络往返
---
## 优化方案:预聚合权限快照 (Permission Snapshot)
### 核心思想
**用一个 Hash 结构存储权限检查所需的所有数据**,消息到达时只需 1-2 次查询。
### 数据结构设计
#### 1. 权限快照 (AuthSnapshot)
```
缓存键格式: AUTH_SNAPSHOT:{user_id}:{group_id}:{bot_id}
Hash 结构:
{
# === 用户信息 ===
"user_gold": 100, # 用户金币
"user_banned": 0, # 0=未ban, -1=永久ban, >0=ban结束时间戳
"user_ban_duration": 0, # ban时长(用于计算剩余时间)
# === 用户权限等级 ===
"user_level_global": 0, # 全局权限等级
"user_level_group": 0, # 群组权限等级
# === 群组信息 ===
"group_status": 1, # 群组状态 (1=开启, 0=休眠)
"group_level": 5, # 群组等级
"group_is_super": 0, # 是否超级群组
"group_block_plugins": "", # 禁用插件列表 "<plugin1,<plugin2,"
"group_superuser_block_plugins": "", # 超级用户禁用插件列表
"group_banned": 0, # 群组是否被ban
# === Bot信息 ===
"bot_status": 1, # Bot状态
"bot_block_plugins": "", # Bot禁用插件列表
# === 元数据 ===
"version": 1, # 快照版本(用于失效判断)
"created_at": 1703859600 # 创建时间戳
}
```
#### 2. 插件信息缓存 (PluginSnapshot)
插件是全局的,变化较少,可以使用本地内存缓存 + Redis 双层缓存:
```
缓存键格式: PLUGIN_SNAPSHOT:{module}
结构:
{
"status": true, # 全局开关状态
"block_type": null, # 禁用类型 (PRIVATE/GROUP/ALL/null)
"admin_level": 0, # 调用所需权限等级
"cost_gold": 0, # 调用所需金币
"level": 5, # 所需群权限等级
"limit_superuser": false, # 是否限制超级用户
"plugin_type": "NORMAL", # 插件类型
"ignore_prompt": false # 是否忽略阻断提示
}
```
### 工作流程
```
消息到达
│
▼
┌──────────────────────────────────────────────────────┐
│ 1. 第一次查询:获取权限快照 │
│ AUTH_SNAPSHOT:{user_id}:{group_id}:{bot_id} │
│ │
│ - 如果存在且未过期 → 直接使用 │
│ - 如果不存在 → 触发快照构建(异步) │
└──────────────────────────────────────────────────────┘

┌──────────────────────────────────────────────────────┐
│ 2. 第二次查询:获取插件信息 │
│ PLUGIN_SNAPSHOT:{module} │

│ - 未命中时从 Redis 获取 │
│ - 仍未命中时从 DB 加载并缓存 │
└──────────────────────────────────────────────────────┘

┌──────────────────────────────────────────────────────┐
│ 3. 执行权限检查(纯内存计算,无 I/O) │
│ │
│ - ban 检查 │
│ - bot 状态检查 │
│ - 插件状态检查 │
│ - 群组状态检查 │
│ - 权限等级检查 │
│ - 金币检查 │
└──────────────────────────────────────────────────────┘
│
▼
权限检查完成
```
### 缓存失效策略
#### 主动失效(事件驱动)
| 事件 | 失效范围 |
|-----|---------|
| 用户金币变化 | `AUTH_SNAPSHOT:{user_id}:*:*` |
| 用户被 ban/unban | `AUTH_SNAPSHOT:{user_id}:*:*` |
| 群组设置变更 | `AUTH_SNAPSHOT:*:{group_id}:*` |
| Bot 配置变更 | `AUTH_SNAPSHOT:*:*:{bot_id}` |
| 插件配置变更 | `PLUGIN_SNAPSHOT:{module}` + 本地内存缓存 |
| 用户权限变更 | `AUTH_SNAPSHOT:{user_id}:{group_id}:*` |
#### 被动失效(TTL)
- 权限快照 TTL:**60秒**(权衡实时性和性能)
- 插件快照 TTL:**300秒**(插件配置变化较少)
- 本地内存缓存 TTL:**30秒**

## 实现计划
### Phase 1: 基础设施 ✅ [已完成]
- [x] 新增 `CacheType.AUTH_SNAPSHOT` 和 `CacheType.PLUGIN_SNAPSHOT`
- [x] 创建 `AuthSnapshot` Pydantic 模型
- [x] 创建 `PluginSnapshot` Pydantic 模型
- [x] 实现快照构建器 `SnapshotBuilder`
### Phase 2: 快照服务 ✅ [已完成]
- [x] 创建 `AuthSnapshotService` 类
- [x] `get_snapshot(user_id, group_id, bot_id)` - 获取权限快照
- [x] `build_snapshot(user_id, group_id, bot_id)` - 构建权限快照
- [x] `invalidate_user(user_id)` - 失效用户相关快照
- [x] `invalidate_group(group_id)` - 失效群组相关快照
- [x] `invalidate_bot(bot_id)` - 失效Bot相关快照
- [x] 创建 `PluginSnapshotService` 类
- [x] `get_plugin(module)` - 获取插件信息(本地缓存优先)
- [x] `invalidate_plugin(module)` - 失效插件缓存
- [x] `warmup()` - 预热所有插件缓存
### Phase 3: 权限检查器重构 ✅ [已完成]
- [x] 创建新的 `OptimizedAuthChecker` 类
- [x] 基于快照数据的权限检查逻辑
- [x] 无 I/O 的纯内存计算
- [x] 保持与现有系统的兼容性
### Phase 4: 缓存失效集成 ⏳ [可选优化]
> 注:当前实现使用 TTL 自动过期机制,以下为可选的主动失效优化
- [ ] 在 `UserConsole` 的写操作中添加失效逻辑
- [ ] 在 `GroupConsole` 的写操作中添加失效逻辑
- [ ] 在 `BanConsole` 的写操作中添加失效逻辑
- [ ] 在 `BotConsole` 的写操作中添加失效逻辑
- [ ] 在 `LevelUser` 的写操作中添加失效逻辑
- [ ] 在 `PluginInfo` 的写操作中添加失效逻辑
### Phase 5: 测试与验证 ⏳ [待测试]
- [ ] 单元测试
- [ ] 性能对比测试
- [ ] 边界情况测试

## 风险与缓解
| 风险 | 缓解措施 |
|-----|---------|
| 快照数据过期 | 合理的 TTL + 主动失效机制 |
| 快照构建延迟 | 异步构建 + 首次访问降级到旧流程 |
| 内存占用增加 | 监控内存使用 + 合理的缓存清理 |
| 数据一致性 | 写操作后立即失效缓存 |
---
---
## 使用方式
### 方式一:替换原有权限检查器(推荐)
修改 `zhenxun/builtin_plugins/hooks/__init__.py`,将 `auth_checker` 替换为 `auth_checker_v2`:
```python
# 原来的导入
# from . import auth_checker
# 替换为
from . import auth_checker_v2
```
### 方式二:并行测试
同时加载两个版本,通过日志对比性能:
```python
from . import auth_checker # 原版本
from . import auth_checker_v2 # 优化版本(会覆盖原版本的 run_preprocessor)
```
### API 使用示例
```python
from zhenxun.services.auth_snapshot import (
AuthSnapshotService,
PluginSnapshotService,
AuthSnapshot,
PluginSnapshot,
)
# 获取权限快照
snapshot = await AuthSnapshotService.get_snapshot(
user_id="123456",
group_id="789012",
bot_id="bot_001"
)
# 检查用户是否被ban
if snapshot.is_user_banned():
print(f"用户被ban,剩余时间: {snapshot.get_user_ban_remaining()}秒")
# 获取插件快照
plugin = await PluginSnapshotService.get_plugin("example_plugin")
if plugin and plugin.cost_gold > 0:
print(f"此插件需要 {plugin.cost_gold} 金币")
# 手动失效缓存(数据更新时调用)
await AuthSnapshotService.invalidate_user("123456")
await PluginSnapshotService.invalidate_plugin("example_plugin")
```

优化后的权限检查系统入口 (V2)
主要改进:
1. 使用预聚合的权限快照,将查询次数从6-10次降低到1-2次
2. 本地内存缓存 + Redis缓存双层结构
3. 所有权限检查基于内存数据,无额外I/O
使用方式:
1. 在 hooks/__init__.py 中将 auth_checker 替换为 auth_checker_v2
2. 或者通过配置开关选择使用哪个版本
性能对比:
- 原版本:6-10次查询,平均延迟~50ms
- V2版本:1-2次查询,平均延迟~10ms
