    end

    subgraph "基础层 (Base)"

    A1 --> B1
    A2 --> B2
    B1 --> C1
    B2 --> C2
    C1 --> D1
    C2 --> D2
```

### 状态管理架构

采用 Pinia 进行状态管理，按模块划分：

```typescript
// stores/index.ts
export interface AppState {
  // 用户状态
  user: UserState;
  // 权限状态
  permission: PermissionState;
  // 应用设置
  settings: SettingsState;
  // 业务数据
  business: BusinessState;
}

// 状态模块示例
export const useUserStore = defineStore('user', () => {
  const userInfo = ref<UserInfo | null>(null);
  const token = ref<string>('');
  const permissions = ref<string[]>([]);

  const login = async (credentials: LoginCredentials) => {
    // 登录逻辑
  };

  const logout = async () => {
    // 登出逻辑
  };

  return {
    userInfo,
    token,
    permissions,
    login,
    logout,
  };
});
```

### 路由架构

采用动态路由 + 权限控制的方式：

```typescript
// router/index.ts
const router = createRouter({
  history: createWebHistory(),
  routes: [
    // 静态路由
    {
      path: '/login',
      component: LoginView,
      meta: { requiresAuth: false },
    },
    // 动态路由（根据权限加载）
    {
      path: '/dashboard',
      component: DashboardLayout,
      meta: { requiresAuth: true },
      children: dynamicRoutes,
    },
  ],
});

// 路由守卫
router.beforeEach(async (to, from, next) => {
  const userStore = useUserStore();

  if (to.meta.requiresAuth && !userStore.token) {
    next('/login');
  } else {
    // 权限验证
    const hasPermission = await checkPermission(to);
    hasPermission ? next() : next('/403');
  }
});
```

### API架构

统一的API请求层：

```typescript
// api/base.ts
class ApiClient {
  private instance: AxiosInstance;

  constructor() {
    this.instance = axios.create({
      baseURL: import.meta.env.VITE_API_URL,
      timeout: 10000,
    });

    this.setupInterceptors();
  }

  private setupInterceptors() {
    // 请求拦截器
    this.instance.interceptors.request.use((config) => {
      const token = getToken();
      if (token) {
        config.headers.Authorization = `Bearer ${token}`;
      }
      return config;
    });

    // 响应拦截器
    this.instance.interceptors.response.use(
      (response) => response.data,
      (error) => this.handleError(error),
    );
  }
}

// API模块化
export const accountApi = {
  getList: (params: AccountListParams) =>
    apiClient.get<AccountListResponse>('/accounts', { params }),

  create: (data: CreateAccountData) =>
    apiClient.post<Account>('/accounts', data),

  update: (id: string, data: UpdateAccountData) =>
    apiClient.put<Account>(`/accounts/${id}`, data),
};
```

    B2 --> C2
    D1 --> A1
    D2 --> A2
```

### 核心模块

#### 1. 用户认证模块

```javascript
// auth/auth.service.js
class AuthService {
  async login(credentials) {
    // 用户验证
    const user = await this.validateUser(credentials);

    // 生成token
    const token = this.generateJWT(user);

    // 记录登录日志
    await this.logLoginActivity(user);

    return { user, token };
  }

  async validateToken(token) {
    try {
      const decoded = jwt.verify(token, process.env.JWT_SECRET);
      const user = await User.findById(decoded.userId);
      return user;
    } catch (error) {
      throw new UnauthorizedError('Invalid token');
    }
  }
}
```

#### 2. 权限控制模块

```javascript
// permission/permission.service.js
class PermissionService {
  async checkPermission(userId, resource, action) {
    const userRoles = await this.getUserRoles(userId);
    const permissions = await this.getRolePermissions(userRoles);

    return permissions.some(
      (permission) =>
        permission.resource === resource && permission.action === action,
    );
  }

  middleware() {
    return async (req, res, next) => {
      const { user } = req;
      const { resource, action } = req.route.meta;

      const hasPermission = await this.checkPermission(
        user.id,
        resource,
        action,
      );

      if (hasPermission) {
        next();
      } else {
        res.status(403).json({ error: 'Forbidden' });
      }
    };
  }
}
```

#### 3. 消息处理模块

```javascript
// message/message.service.js
class MessageService {
  async sendBulkMessage(taskData) {
    const { templateId, targetUsers, scheduledTime } = taskData;

    // 创建发送任务
    const task = await this.createTask(taskData);

    // 如果是定时发送
    if (scheduledTime) {
      await this.scheduleTask(task, scheduledTime);
    } else {
      await this.executeTask(task);
    }

    return task;
  }

  async executeTask(task) {
    const { id, targetUsers, template } = task;
    const results = [];

    for (const user of targetUsers) {
      try {
        // 渲染消息模板
        const message = this.renderTemplate(template, user);

        // 发送消息
        const result = await this.sendTelegramMessage(user.telegramId, message);

        // 记录发送结果
        await this.recordSendResult(task.id, user.id, result);

        results.push({ userId: user.id, status: 'success' });
      } catch (error) {
        results.push({
          userId: user.id,
          status: 'failed',
          error: error.message,
        });
      }
    }

    // 更新任务状态
    await this.updateTaskStatus(id, 'completed', results);
  }
}
```

### 数据模型

// models/User.js
const UserSchema = new Schema({
  username: { type: String, required: true, unique: true },
  email: { type: String, required: true, unique: true },

        string created_by FK
        datetime created_at
        datetime updated_at
    }
```

### 数据表设计

#### 核心业务表

1. **用户表 (users)**

```sql
CREATE TABLE users (
  id VARCHAR(36) PRIMARY KEY,
  username VARCHAR(50) UNIQUE NOT NULL,
  email VARCHAR(100) UNIQUE NOT NULL,
  password_hash VARCHAR(255) NOT NULL,
  profile JSON,
  status ENUM('active', 'inactive', 'suspended') DEFAULT 'active',
  last_login TIMESTAMP NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

  INDEX idx_username (username),
  INDEX idx_email (email),
  INDEX idx_status (status)
);
```

2. **Telegram账号表 (telegram_accounts)**

```sql
CREATE TABLE telegram_accounts (
  id VARCHAR(36) PRIMARY KEY,
  telegram_id VARCHAR(20) UNIQUE NOT NULL,
  username VARCHAR(50),
  first_name VARCHAR(50),
  last_name VARCHAR(50),
  phone VARCHAR(20),
  status ENUM('active', 'inactive', 'blocked') DEFAULT 'active',
  metadata JSON,
  managed_by VARCHAR(36),
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

  INDEX idx_telegram_id (telegram_id),
  INDEX idx_username (username),
  INDEX idx_managed_by (managed_by),
  FOREIGN KEY (managed_by) REFERENCES users(id)
);
```

3. **消息任务表 (message_tasks)**

```sql
CREATE TABLE message_tasks (
  id VARCHAR(36) PRIMARY KEY,
  name VARCHAR(100) NOT NULL,
  description TEXT,
  template_id VARCHAR(36),
  target_users JSON NOT NULL,
  scheduling JSON,
  status ENUM('pending', 'running', 'completed', 'failed', 'cancelled') DEFAULT 'pending',
  progress JSON,
  created_by VARCHAR(36) NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

  INDEX idx_status (status),
  INDEX idx_created_by (created_by),
  INDEX idx_created_at (created_at),
  FOREIGN KEY (created_by) REFERENCES users(id),
  FOREIGN KEY (template_id) REFERENCES message_templates(id)
);
```

### 缓存策略

#### Redis 数据结构设计

```javascript
// 缓存键命名规范
const CACHE_KEYS = {
  // 用户相关
  USER_INFO: 'user:info:{userId}',
  USER_PERMISSIONS: 'user:permissions:{userId}',
  USER_SESSION: 'session:{sessionId}',

  // 任务相关
  TASK_STATUS: 'task:status:{taskId}',
  TASK_PROGRESS: 'task:progress:{taskId}',
  TASK_QUEUE: 'task:queue',

  // 统计数据
  DAILY_STATS: 'stats:daily:{date}',
  USER_ACTIVITY: 'activity:user:{userId}',

  // 配置缓存
  SYSTEM_CONFIG: 'config:system',
  RATE_LIMIT: 'rate_limit:{userId}:{endpoint}',
};

// 缓存操作示例
class CacheService {
  async getUserInfo(userId) {
    const cacheKey = CACHE_KEYS.USER_INFO.replace('{userId}', userId);
    let userInfo = await redis.get(cacheKey);

    if (!userInfo) {
      userInfo = await User.findById(userId);
      await redis.setex(cacheKey, 3600, JSON.stringify(userInfo)); // 1小时过期
    } else {
      userInfo = JSON.parse(userInfo);
    }

    return userInfo;
  }

  async setTaskProgress(taskId, progress) {
    const cacheKey = CACHE_KEYS.TASK_PROGRESS.replace('{taskId}', taskId);
    await redis.setex(cacheKey, 86400, JSON.stringify(progress)); // 24小时过期

    // 发布进度更新事件
    await redis.publish(
      'task:progress:update',
      JSON.stringify({
        taskId,
        progress,
      }),
    );
  }
}
```

## 🔐 安全架构

### 认证与授权

#### JWT认证流程

```mermaid
sequenceDiagram
    participant Client
    participant Gateway
    participant AuthService
    participant Database

    Client->>Gateway: 登录请求 (username, password)
    Gateway->>AuthService: 验证凭据
    AuthService->>Database: 查询用户信息
    Database-->>AuthService: 返回用户数据
    AuthService->>AuthService: 验证密码
    AuthService->>AuthService: 生成JWT Token
    AuthService-->>Gateway: 返回Token和用户信息
    Gateway-->>Client: 返回认证结果

    Note over Client: 后续请求携带Token
    Client->>Gateway: API请求 (Header: Authorization)
    Gateway->>AuthService: 验证Token
    AuthService-->>Gateway: 返回用户信息
    Gateway->>Gateway: 检查权限
    Gateway-->>Client: 返回API响应
```

#### 权限控制模型

采用RBAC (Role-Based Access Control) 模型：

```typescript
// 权限定义
interface Permission {
  id: string;
  resource: string; // 资源类型: account, message, task
  action: string; // 操作类型: create, read, update, delete
  conditions?: {
    // 条件限制
    owner?: boolean; // 只能操作自己的资源
    department?: string; // 部门限制
  };
}

// 角色定义
interface Role {
  id: string;
  name: string;
  permissions: Permission[];
  inherits?: string[]; // 继承其他角色
}

// 权限检查
class PermissionChecker {
  async checkPermission(
    userId: string,
    resource: string,
    action: string,
    resourceData?: any,
  ): Promise<boolean> {
    const userRoles = await this.getUserRoles(userId);
    const permissions = await this.flattenPermissions(userRoles);

    return permissions.some((permission) => {
      // 基础权限匹配
      if (permission.resource !== resource || permission.action !== action) {
        return false;
      }

      // 条件检查
      if (permission.conditions?.owner && resourceData?.ownerId !== userId) {
        return false;
      }

      return true;
    });
  }
}
```

### 数据安全

#### 敏感数据加密

```javascript
// 数据加密服务
class CryptoService {
  constructor() {
    this.algorithm = 'aes-256-gcm';
    this.secretKey = process.env.ENCRYPTION_KEY;
  }

  encrypt(text) {
    const iv = crypto.randomBytes(16);
    const cipher = crypto.createCipher(this.algorithm, this.secretKey);
    cipher.setAAD(Buffer.from('additional-data'));

    let encrypted = cipher.update(text, 'utf8', 'hex');
    encrypted += cipher.final('hex');

    const authTag = cipher.getAuthTag();

    return {
      encrypted,
      iv: iv.toString('hex'),
      authTag: authTag.toString('hex'),
    };
  }

  decrypt(encryptedData) {
    const decipher = crypto.createDecipher(this.algorithm, this.secretKey);
    decipher.setAAD(Buffer.from('additional-data'));
    decipher.setAuthTag(Buffer.from(encryptedData.authTag, 'hex'));

    let decrypted = decipher.update(encryptedData.encrypted, 'hex', 'utf8');
    decrypted += decipher.final('utf8');

    return decrypted;
  }
}

// 模型层数据加密
class User extends Model {
  static encrypt = ['password', 'phone', 'email'];

  static beforeSave(user) {
    this.encrypt.forEach((field) => {
      if (user[field] && user.isModified(field)) {
        user[field] = cryptoService.encrypt(user[field]);
      }
    });
  }

  static afterFind(user) {
    this.encrypt.forEach((field) => {
      if (user[field] && typeof user[field] === 'object') {
        user[field] = cryptoService.decrypt(user[field]);
      }
    });
  }
}
```

#### API安全防护

```javascript
// API限流中间件
class RateLimitMiddleware {
  constructor(options = {}) {
    this.windowMs = options.windowMs || 60000; // 1分钟
    this.maxRequests = options.max || 100;
    this.skipSuccessfulRequests = options.skipSuccessfulRequests || false;
  }

  middleware() {
    return async (req, res, next) => {
      const key = `rate_limit:${req.ip}:${req.route.path}`;
      const current = await redis.get(key);

      if (current && parseInt(current) >= this.maxRequests) {
        return res.status(429).json({
          error: 'Too Many Requests',
          retryAfter: this.windowMs / 1000,
        });
      }

      await redis
        .multi()
        .incr(key)
        .expire(key, this.windowMs / 1000)
        .exec();

      next();
    };
  }
}

// XSS防护
app.use(
  helmet({
    contentSecurityPolicy: {
      directives: {
        defaultSrc: ["'self'"],
        styleSrc: ["'self'", "'unsafe-inline'"],
        scriptSrc: ["'self'"],
        imgSrc: ["'self'", 'data:', 'https:'],
      },
    },
    hsts: {
      maxAge: 31536000,
      includeSubDomains: true,
      preload: true,
    },
  }),
);

// SQL注入防护 (使用参数化查询)
class DatabaseService {
  async findUser(conditions) {
    const query = 'SELECT * FROM users WHERE username = ? AND status = ?';
    return await this.connection.query(query, [
      conditions.username,
      conditions.status,
    ]);
  }
}
```

## ⚡ 性能优化

### 前端性能优化

#### 1. 构建优化

```typescript
// vite.config.ts
export default defineConfig({
  build: {
    rollupOptions: {
      output: {
        // 代码分割
        manualChunks: {
          vendor: ['vue', 'vue-router', 'pinia'],
          antd: ['ant-design-vue'],
          utils: ['lodash', 'dayjs'],
        },
      },
    },
    // 压缩配置
    minify: 'terser',
    terserOptions: {
      compress: {
        drop_console: true,
        drop_debugger: true,
      },
    },
  },

  // 开发服务器优化
  server: {
    hmr: {
      overlay: false,
    },
  },

  // 依赖预构建
  optimizeDeps: {
    include: ['vue', 'vue-router', 'pinia', 'ant-design-vue'],
  },
});
```

#### 2. 资源优化

```typescript
// build/image-optimizer.ts
export async function optimizeImages(options: OptimizationOptions) {
  const imageFiles = await glob('**/*.{png,jpg,jpeg,gif,svg}', {
    cwd: options.inputDir,
  });

  for (const file of imageFiles) {
    const inputPath = path.join(options.inputDir, file);
    const outputPath = path.join(options.outputDir, file);

    // PNG/JPEG压缩
    if (file.match(/\.(png|jpe?g)$/)) {
      await sharp(inputPath)
        .resize(options.maxWidth, options.maxHeight, {
          fit: 'inside',
          withoutEnlargement: true,
        })
        .jpeg({ quality: options.quality })
        .png({ compressionLevel: 9 })
        .toFile(outputPath);
    }

    // 生成WebP格式
    const webpPath = outputPath.replace(/\.(png|jpe?g)$/, '.webp');
    await sharp(inputPath)
      .webp({ quality: options.webpQuality })
      .toFile(webpPath);
  }
}
```

#### 3. 运行时优化

```vue
<!-- 组件懒加载 -->
<template>
  <div>
    <!-- 虚拟滚动 -->
    <VirtualList :items="largeDataset" :item-height="50" :visible-count="20">
      <template #default="{ item }">
        <ListItem :data="item" />
      </template>
    </VirtualList>

    <!-- 图片懒加载 -->
    <img v-lazy="imageUrl" :alt="description" loading="lazy" />
  </div>
</template>

<script setup lang="ts">
// 组合式函数优化
const { data, loading } = usePagination({
  api: accountApi.getList,
  pageSize: 20,
  immediate: true,
});

// 防抖搜索
const searchKeyword = ref('');
const debouncedSearch = useDebounceFn(() => {
  // 执行搜索
}, 300);

watch(searchKeyword, debouncedSearch);

// 缓存计算结果
const expensiveComputation = computed(() => {
  return heavyCalculation(data.value);
});
</script>
```

### 后端性能优化

#### 1. 数据库优化

```sql
-- 索引优化
CREATE INDEX idx_users_status_created ON users(status, created_at);
CREATE INDEX idx_message_tasks_status_priority ON message_tasks(status, priority, created_at);
CREATE INDEX idx_telegram_accounts_managed_status ON telegram_accounts(managed_by, status);

-- 分区表（按时间分区）
CREATE TABLE message_logs (
    id BIGINT AUTO_INCREMENT,
    task_id VARCHAR(36),
    user_id VARCHAR(36),
    message TEXT,
    status ENUM('sent', 'failed'),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    PRIMARY KEY (id, created_at)
) PARTITION BY RANGE (TO_DAYS(created_at)) (
    PARTITION p2024_01 VALUES LESS THAN (TO_DAYS('2024-02-01')),
    PARTITION p2024_02 VALUES LESS THAN (TO_DAYS('2024-03-01')),
    -- ... 更多分区
);
```

#### 2. 缓存策略

```javascript
// 多级缓存
class CacheManager {
  constructor() {
    this.l1Cache = new Map(); // 内存缓存
    this.l2Cache = redis; // Redis缓存
  }

  async get(key) {
    // L1缓存
    if (this.l1Cache.has(key)) {
      return this.l1Cache.get(key);
    }

    // L2缓存
    const l2Value = await this.l2Cache.get(key);
    if (l2Value) {
      const value = JSON.parse(l2Value);
      this.l1Cache.set(key, value);
      return value;
    }

    return null;
  }

  async set(key, value, ttl = 3600) {
    // 同时设置两级缓存
    this.l1Cache.set(key, value);
    await this.l2Cache.setex(key, ttl, JSON.stringify(value));
  }
}

// 查询优化
class UserService {
  async getUsers(filters, pagination) {
    const cacheKey = `users:${JSON.stringify({ filters, pagination })}`;

    // 尝试从缓存获取
    let result = await cacheManager.get(cacheKey);
    if (result) {
      return result;
    }

    // 数据库查询优化
    const query = User.find(filters)
      .populate('roles', 'name permissions') // 只选择需要的字段
      .limit(pagination.pageSize)
      .skip(pagination.offset)
      .sort({ createdAt: -1 });

    result = await query.exec();

    // 缓存结果
    await cacheManager.set(cacheKey, result, 300); // 5分钟缓存

    return result;
  }
}
```

#### 3. 消息队列优化

```javascript
// 批量处理消息发送
class MessageQueue {
  constructor() {
    this.queue = [];
    this.batchSize = 100;
    this.processingInterval = 1000; // 1秒

    this.startProcessing();
  }

  add(message) {
    this.queue.push(message);
  }

  startProcessing() {
    setInterval(async () => {
      if (this.queue.length === 0) return;

      const batch = this.queue.splice(0, this.batchSize);
      await this.processBatch(batch);
    }, this.processingInterval);
  }

  async processBatch(messages) {
    const promises = messages.map((message) =>
      this.sendMessage(message).catch((error) => ({
        message,
        error: error.message,
      })),
    );

    const results = await Promise.allSettled(promises);

    // 记录失败的消息，用于重试
    const failures = results
      .filter((result) => result.status === 'rejected' || result.value.error)
      .map((result) => result.value || result.reason);

    if (failures.length > 0) {
      await this.handleFailures(failures);
    }
  }
}
```

## 📊 监控体系

### 应用性能监控

#### 1. 前端监控

```typescript
// 性能监控 SDK
class PerformanceMonitor {
  constructor() {
    this.metrics = {
      FCP: 0, // First Contentful Paint
      LCP: 0, // Largest Contentful Paint
      FID: 0, // First Input Delay
      CLS: 0, // Cumulative Layout Shift
    };

    this.init();
  }

  init() {
    // Web Vitals监控
    import('web-vitals').then(({ getFCP, getLCP, getFID, getCLS }) => {
      getFCP(this.onFCP.bind(this));
      getLCP(this.onLCP.bind(this));
      getFID(this.onFID.bind(this));
      getCLS(this.onCLS.bind(this));
    });

    // 错误监控
    window.addEventListener('error', this.onError.bind(this));
    window.addEventListener(
      'unhandledrejection',
      this.onUnhandledRejection.bind(this),
    );
  }

  onFCP(metric) {
    this.metrics.FCP = metric.value;
    this.sendMetric('FCP', metric);
  }

  onError(event) {

    });
  }
}

// Vue应用监控插件
const monitoringPlugin = {
  install(app) {
    // 全局错误处理
    app.config.errorHandler = (err, vm, info) => {
      console.error('Vue Error:', err, info);

      // 发送错误报告
      fetch('/api/monitoring/errors', {

    };

    // 路由变化监控
    const router = app.config.globalProperties.$router;
    router.beforeEach((to, from) => {
      const startTime = performance.now();

      router.afterEach(() => {
        const endTime = performance.now();
        const navigationTime = endTime - startTime;

        // 记录路由性能
        fetch('/api/monitoring/navigation', {

          headers: { 'Content-Type': 'application/json' },
          body: JSON.stringify({
            from: from.path,
            to: to.path,
            duration: navigationTime,
            timestamp: Date.now(),
          }),
        });
      });

## 🔧 扩展性设计

### 水平扩展

#### 1. 微服务架构

```mermaid

        A1[Kong/Istio Gateway]
    end

    subgraph "Core Services"
        B1[User Service]

        B5[Analytics Service]
    end

    subgraph "Supporting Services"

    end

    subgraph "Data Layer"

    A1 --> B5

    B1 --> D1
    B3 --> D2
    B5 --> D3
    B1 --> D4
    B3 --> D4
```

#### 2. 数据库分片

```javascript
// 数据库分片策略
class DatabaseSharding {
  constructor() {
    this.shards = [
      { id: 'shard1', host: 'db1.example.com', range: [0, 1000000] },
      { id: 'shard2', host: 'db2.example.com', range: [1000001, 2000000] },
      { id: 'shard3', host: 'db3.example.com', range: [2000001, 3000000] },
    ];
  }

  getShardByUserId(userId) {
    const numericId = parseInt(userId.replace(/\D/g, ''));
    return this.shards.find(
      (shard) => numericId >= shard.range[0] && numericId <= shard.range[1],
    );
  }

  async queryUser(userId) {
    const shard = this.getShardByUserId(userId);
    const connection = await this.getConnection(shard.host);
    return await connection.query('SELECT * FROM users WHERE id = ?', [userId]);
  }

  async queryAllShards(query, params) {
    const promises = this.shards.map((shard) => {
      const connection = this.getConnection(shard.host);
      return connection.query(query, params);
    });

    const results = await Promise.all(promises);
    return results.flat();
  }
}
```

### 插件化架构

#### 1. 插件系统设计

```typescript
// 插件接口定义
interface Plugin {
  name: string;
  version: string;
  dependencies?: string[];

  install(app: Application): void;
  uninstall?(app: Application): void;
  configure?(config: PluginConfig): void;
}

// 插件管理器
class PluginManager {
  private plugins = new Map<string, Plugin>();
  private loadOrder: string[] = [];

  async loadPlugin(pluginPath: string): Promise<void> {
    const plugin = await import(pluginPath);

    // 检查依赖
    if (plugin.dependencies) {
      for (const dep of plugin.dependencies) {
        if (!this.plugins.has(dep)) {
          throw new Error(`Plugin dependency not found: ${dep}`);
        }
      }
    }

    // 安装插件
    plugin.install(this.app);
    this.plugins.set(plugin.name, plugin);
    this.loadOrder.push(plugin.name);
  }

  unloadPlugin(name: string): void {
    const plugin = this.plugins.get(name);
    if (plugin && plugin.uninstall) {
      plugin.uninstall(this.app);
    }

    this.plugins.delete(name);
    const index = this.loadOrder.indexOf(name);
    if (index > -1) {
      this.loadOrder.splice(index, 1);
    }
  }
}

// 插件示例：短信发送插件
export class SmsPlugin implements Plugin {
  name = 'sms-plugin';
  version = '1.0.0';

  install(app: Application) {
    // 注册短信服务
    app.service('sms', new SmsService());

    // 注册API路由
    app.router.post('/api/sms/send', this.sendSms.bind(this));

    // 注册事件监听器
    app.on('user:created', this.sendWelcomeSms.bind(this));
  }

  private async sendSms(req: Request, res: Response) {
    const { phone, message } = req.body;
    const result = await app.service('sms').send(phone, message);
    res.json(result);
  }

  private async sendWelcomeSms(user: User) {
    if (user.phone) {
      await app.service('sms').send(user.phone, '欢迎使用我们的服务！');
    }
  }
}
```

### 配置管理

#### 1. 动态配置系统

```typescript
// 配置中心客户端
class ConfigCenter {
  private cache = new Map<string, any>();
  private watchers = new Map<string, Function[]>();

  constructor(private client: ConsulClient) {
    this.startWatching();
  }

  async get<T>(key: string, defaultValue?: T): Promise<T> {
    // 先从缓存获取
    if (this.cache.has(key)) {
      return this.cache.get(key);
    }

    // 从配置中心获取
    try {
      const value = await this.client.kv.get(key);
      if (value) {
        const parsed = JSON.parse(value);
        this.cache.set(key, parsed);
        return parsed;
      }
    } catch (error) {
      console.error(`Failed to get config ${key}:`, error);
    }

    return defaultValue as T;
  }

  async set(key: string, value: any): Promise<void> {
    await this.client.kv.set(key, JSON.stringify(value));
    this.cache.set(key, value);

    // 通知观察者
    const watchers = this.watchers.get(key) || [];
    watchers.forEach((callback) => callback(value));
  }

  watch(key: string, callback: (value: any) => void): void {
    if (!this.watchers.has(key)) {
      this.watchers.set(key, []);
    }
    this.watchers.get(key)!.push(callback);
  }

  private startWatching(): void {
    // 定期检查配置变更
    setInterval(async () => {
      for (const key of this.cache.keys()) {
        try {
          const newValue = await this.client.kv.get(key);
          const cached = this.cache.get(key);

          if (JSON.stringify(newValue) !== JSON.stringify(cached)) {
            this.cache.set(key, newValue);

            const watchers = this.watchers.get(key) || [];
            watchers.forEach((callback) => callback(newValue));
          }
        } catch (error) {
          console.error(`Failed to watch config ${key}:`, error);
        }
      }
    }, 5000);
  }
}

// 使用示例
const config = new ConfigCenter(consulClient);

// 监听配置变更
config.watch('telegram.api.rate_limit', (newLimit) => {
  console.log('Rate limit updated:', newLimit);
  rateLimiter.updateLimit(newLimit);
});

// 获取配置
const rateLimit = await config.get('telegram.api.rate_limit', 100);
```
