2. 进阶开发模式
企业级机器人架构
typescript
import { Bot, BotConfig } from 'qq-official-bot'
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
}
