class EnterpriseBot {
  private bot: Bot
  private services: Map<string, any> = new Map()
  private middleware: Array<Function> = []
  
  constructor(config: BotConfig) {
    this.bot = new Bot(config)
    this.initializeServices()
    this.setupMiddleware()
    this.setupEventHandlers()
  }
  
  private initializeServices() {
    // 注册自定义服务
    this.services.set('analytics', new AnalyticsService())
    this.services.set('moderation', new ModerationService())
    this.services.set('scheduler', new SchedulerService())
    this.services.set('cache', new CacheService())
  }
  
  private setupMiddleware() {
    // 安全中间件
    this.middleware.push(this.securityMiddleware.bind(this))
    // 限流中间件
    this.middleware.push(this.rateLimitMiddleware.bind(this))
    // 日志中间件
    this.middleware.push(this.loggingMiddleware.bind(this))
  }
  
  private async securityMiddleware(ctx: any, next: Function) {
    // 安全检查逻辑
    const isValid = await this.validateMessage(ctx.message)
    if (!isValid) {
      console.warn('Security check failed:', ctx.message.id)
      return
    }
    await next()
  }
  
  private async rateLimitMiddleware(ctx: any, next: Function) {
    // 限流检查
    const key = `user:${ctx.user.id}`
    const requests = await this.services.get('cache').get(key) || 0
    
    if (requests > 10) { // 每分钟最多10次请求
      await this.bot.message.send(ctx.channel.id, [{
        type: 'text',
        text: '操作过于频繁,请稍后再试'
      }])
      return
    }
    
    await this.services.get('cache').set(key, requests + 1, 60)
    await next()
  }
  
  private async loggingMiddleware(ctx: any, next: Function) {
    const start = Date.now()
    await next()
    const duration = Date.now() - start
    
    this.services.get('analytics').logRequest({
      userId: ctx.user.id,
      channelId: ctx.channel.id,
      command: ctx.command,
      duration,
      timestamp: new Date()
    })
  }
}

插件系统设计

typescript
// 插件接口定义
interface BotPlugin {
  name: string
  version: string
  description: string
  dependencies?: string[]
  
  onLoad(bot: Bot): Promise<void>
  onUnload(bot: Bot): Promise<void>
  onMessage?(ctx: MessageContext): Promise<void>
  onCommand?(ctx: CommandContext): Promise<void>
}

// 插件管理器
class PluginManager {
  private plugins: Map<string, BotPlugin> = new Map()
  private loadOrder: string[] = []
  
  constructor(private bot: Bot) {}
  
  async loadPlugin(plugin: BotPlugin): Promise<void> {
    // 检查依赖
    if (plugin.dependencies) {
      for (const dep of plugin.dependencies) {
        if (!this.plugins.has(dep)) {
          throw new Error(`Missing dependency: ${dep}`)
        }
      }
    }
    
    // 加载插件
    await plugin.onLoad(this.bot)
    this.plugins.set(plugin.name, plugin)
    this.loadOrder.push(plugin.name)
    
    console.log(`Plugin loaded: ${plugin.name} v${plugin.version}`)
  }
  
  async unloadPlugin(name: string): Promise<void> {
    const plugin = this.plugins.get(name)
    if (!plugin) return
    
    await plugin.onUnload(this.bot)
    this.plugins.delete(name)
    
    const index = this.loadOrder.indexOf(name)
    if (index > -1) {
      this.loadOrder.splice(index, 1)
    }
    
    console.log(`Plugin unloaded: ${name}`)
  }
  
  async handleMessage(ctx: MessageContext): Promise<void> {
    for (const name of this.loadOrder) {
      const plugin = this.plugins.get(name)
      if (plugin?.onMessage) {
        try {
          await plugin.onMessage(ctx)
        } catch (error) {
          console.error(`Plugin ${name} error:`, error)
        }
      }
    }
  }
}

// 示例插件:自动回复
class AutoReplyPlugin implements BotPlugin {
  name = 'auto-reply'
  version = '1.0.0'
  description = '自动回复插件'
  
  private replyRules: Map<string, string> = new Map()
  
  async onLoad(bot: Bot): Promise<void> {
    // 加载回复规则
    this.replyRules.set('你好', '你好!我是QQ机器人助手')
    this.replyRules.set('帮助', '输入 /help 查看可用命令')
  }
  
  async onUnload(bot: Bot): Promise<void> {
    this.replyRules.clear()
  }
  
  async onMessage(ctx: MessageContext): Promise<void> {
    const content = ctx.message.content
    const reply = this.replyRules.get(content)
    
    if (reply) {
      await ctx.bot.message.send(ctx.channel.id, [{
        type: 'text',
        text: reply
      }])
    }
  }
}

3. 高级消息处理

智能消息路由

typescript
class MessageRouter {
  private routes: Map<string, RouteHandler> = new Map()
  private middleware: Middleware[] = []
  
  use(middleware: Middleware): this {
    this.middleware.push(middleware)
    return this
  }
  
  route(pattern: string, handler: RouteHandler): this {
    this.routes.set(pattern, handler)
    return this
  }
  
  async handle(message: Message): Promise<void> {
    const ctx = this.createContext(message)
    
    // 执行中间件
    await this.executeMiddleware(ctx)
    
    // 匹配路由
    for (const [pattern, handler] of this.routes) {
      if (this.matchPattern(pattern, message.content)) {
        await handler(ctx)
        return
      }
    }
    
    // 默认处理
    await this.defaultHandler(ctx)
  }
  
  private matchPattern(pattern: string, content: string): boolean {
    // 支持正则表达式和通配符
    if (pattern.startsWith('/') && pattern.endsWith('/')) {
      const regex = new RegExp(pattern.slice(1, -1))
      return regex.test(content)
    }
    
    // 简单通配符支持
    const regexPattern = pattern
      .replace(/\*/g, '.*')
      .replace(/\?/g, '.')
    
    return new RegExp(`^${regexPattern}$`).test(content)
  }
}

// 使用示例
const router = new MessageRouter()

router
  .use(authMiddleware)
  .use(loggingMiddleware)
  .route('/help*', helpHandler)
  .route('/admin/*', adminHandler)
  .route('/user/profile', userProfileHandler)
  .route('*问好*', greetingHandler)

消息队列和批处理

typescript
class MessageQueue {
  private queue: QueueItem[] = []
  private processing = false
  private batchSize = 10
  private batchInterval = 1000
  
  constructor(private bot: Bot) {
    this.startBatchProcessor()
  }
  
  enqueue(channelId: string, messages: any[], priority = 0): void {
    this.queue.push({
      channelId,
      messages,
      priority,
      timestamp: Date.now()
    })
    
    // 按优先级排序
    this.queue.sort((a, b) => b.priority - a.priority)
  }
  
  private startBatchProcessor(): void {
    setInterval(async () => {
      if (this.processing || this.queue.length === 0) return
      
      this.processing = true
      try {
        await this.processBatch()
      } catch (error) {
        console.error('Batch processing error:', error)
      } finally {
        this.processing = false
      }
    }, this.batchInterval)
  }
  
  private async processBatch(): Promise<void> {
    const batch = this.queue.splice(0, this.batchSize)
    
    // 按频道分组
    const groupedByChannel = new Map<string, QueueItem[]>()
    for (const item of batch) {
      const items = groupedByChannel.get(item.channelId) || []
      items.push(item)
      groupedByChannel.set(item.channelId, items)
    }
    
    // 并行处理不同频道的消息
    const promises = Array.from(groupedByChannel.entries()).map(
      ([channelId, items]) => this.processChannelBatch(channelId, items)
    )
    
    await Promise.allSettled(promises)
  }
  
  private async processChannelBatch(channelId: string, items: QueueItem[]): Promise<void> {
    for (const item of items) {
      try {
        await this.bot.message.send(channelId, item.messages)
        // 频道内消息间隔
        await new Promise(resolve => setTimeout(resolve, 100))
      } catch (error) {
        console.error(`Failed to send message to ${channelId}:`, error)
        
        // 重试机制
        if (item.retryCount < 3) {
          item.retryCount = (item.retryCount || 0) + 1
          this.queue.unshift(item) // 重新添加到队列前端
        }
      }
    }
  }
}

4. 性能优化策略

连接池管理

typescript
class ConnectionPool {
  private connections: Map<string, Connection> = new Map()
  private maxConnections = 10
  private connectionTimeout = 30000
  
  async getConnection(key: string): Promise<Connection> {
    let connection = this.connections.get(key)
    
    if (!connection || !connection.isAlive()) {
      connection = await this.createConnection(key)
      this.connections.set(key, connection)
    }
    
    return connection
  }
  
  private async createConnection(key: string): Promise<Connection> {
    if (this.connections.size >= this.maxConnections) {
      await this.cleanupOldConnections()
    }
    
    const connection = new Connection(key)
    await connection.connect()
    
    // 设置超时清理
    setTimeout(() => {
      this.connections.delete(key)
      connection.disconnect()
    }, this.connectionTimeout)
    
    return connection
  }
  
  private async cleanupOldConnections(): Promise<void> {
    const entries = Array.from(this.connections.entries())
    entries.sort((a, b) => a[1].lastUsed - b[1].lastUsed)
    
    // 清理最旧的连接
    const [key, connection] = entries[0]
    this.connections.delete(key)
    await connection.disconnect()
  }
}

内存缓存优化

typescript
class LRUCache<T> {
  private cache = new Map<string, CacheItem<T>>()
  private maxSize: number
  
  constructor(maxSize = 1000) {
    this.maxSize = maxSize
  }
  
  get(key: string): T | undefined {
    const item = this.cache.get(key)
    if (!item) return undefined
    
    if (item.expiry && Date.now() > item.expiry) {
      this.cache.delete(key)
      return undefined
    }
    
    // 移到最前面(LRU)
    this.cache.delete(key)
    this.cache.set(key, item)
    
    return item.value
  }
  
  set(key: string, value: T, ttl?: number): void {
    // 检查容量
    if (this.cache.size >= this.maxSize && !this.cache.has(key)) {
      // 删除最旧的项
      const firstKey = this.cache.keys().next().value
      this.cache.delete(firstKey)
    }
    
    const expiry = ttl ? Date.now() + ttl * 1000 : undefined
    this.cache.set(key, { value, expiry, createdAt: Date.now() })
  }
  
  clear(): void {
    this.cache.clear()
  }
  
  size(): number {
    return this.cache.size
  }
}

interface CacheItem<T> {
  value: T
  expiry?: number
  createdAt: number
}

5. 监控和日志

综合监控系统

typescript
class BotMonitor {
  private metrics = new Map<string, number>()
  private alerts: AlertRule[] = []
  
  constructor(private bot: Bot) {
    this.setupMetrics()
    this.startMonitoring()
  }
  
  private setupMetrics(): void {
    // 消息统计
    this.bot.on('message.sent', () => {
      this.incrementMetric('messages.sent')
    })
    
    this.bot.on('message.received', () => {
      this.incrementMetric('messages.received')
    })
    
    // 错误统计
    this.bot.on('error', (error) => {
      this.incrementMetric('errors.total')
      this.incrementMetric(`errors.${error.type}`)
    })
    
    // 连接状态
    this.bot.on('connection.open', () => {
      this.setMetric('connection.status', 1)
    })
    
    this.bot.on('connection.close', () => {
      this.setMetric('connection.status', 0)
    })
  }
  
  private startMonitoring(): void {
    setInterval(() => {
      this.checkAlerts()
      this.exportMetrics()
    }, 60000) // 每分钟检查
  }
  
  addAlert(rule: AlertRule): void {
    this.alerts.push(rule)
  }
  
  private checkAlerts(): void {
    for (const rule of this.alerts) {
      const value = this.metrics.get(rule.metric) || 0
      
      if (rule.condition(value)) {
        this.triggerAlert(rule, value)
      }
    }
  }
  
  private async triggerAlert(rule: AlertRule, value: number): Promise<void> {
    const message = `⚠️ 警告: ${rule.name}\n` +
                   `指标: ${rule.metric}\n` +
                   `当前值: ${value}\n` +
                   `描述: ${rule.description}`
    
    // 发送警告到管理频道
    await this.bot.message.send(rule.alertChannel, [{
      type: 'text',
      text: message
    }])
  }
  
  private incrementMetric(key: string): void {
    this.metrics.set(key, (this.metrics.get(key) || 0) + 1)
  }
  
  private setMetric(key: string, value: number): void {
    this.metrics.set(key, value)
  }
  
  private exportMetrics(): void {
    const metricsData = Object.fromEntries(this.metrics)
    
    // 导出到监控系统(如 Prometheus, CloudWatch 等)
    console.log('Metrics:', JSON.stringify(metricsData, null, 2))
  }
}

interface AlertRule {
  name: string
  metric: string
  condition: (value: number) => boolean
  description: string
  alertChannel: string
}

// 使用示例
const monitor = new BotMonitor(bot)

monitor.addAlert({
  name: '错误率过高',
  metric: 'errors.total',
  condition: (value) => value > 10,
  description: '每分钟错误数超过10次',
  alertChannel: 'admin-channel-id'
})

结构化日志

typescript
class StructuredLogger {
  private level: LogLevel = LogLevel.INFO
  
  constructor(private serviceName: string) {}
  
  debug(message: string, meta?: any): void {
    this.log(LogLevel.DEBUG, message, meta)
  }
  
  info(message: string, meta?: any): void {
    this.log(LogLevel.INFO, message, meta)
  }
  
  warn(message: string, meta?: any): void {
    this.log(LogLevel.WARN, message, meta)
  }
  
  error(message: string, error?: Error, meta?: any): void {
    this.log(LogLevel.ERROR, message, { error: error?.stack, ...meta })
  }
  
  private log(level: LogLevel, message: string, meta?: any): void {
    if (level < this.level) return
    
    const logEntry = {
      timestamp: new Date().toISOString(),
      level: LogLevel[level],
      service: this.serviceName,
      message,
      ...meta,
      traceId: this.generateTraceId()
    }
    
    console.log(JSON.stringify(logEntry))
  }
  
  private generateTraceId(): string {
    return Math.random().toString(36).substring(2, 15)
  }
}

enum LogLevel {
  DEBUG = 0,
  INFO = 1,
  WARN = 2,
  ERROR = 3
}
