核心功能模块设计

盲盒抽奖系统

• 概率算法设计（权重分配、保底机制）

  // 奖品权重分配算法（基于概率轮盘）function weightedRandomDraw(prizes) { const totalWeight = prizes.reduce((sum, item) => sum + item.weight, 0); let random = Math.random() * totalWeight; let currentSum = 0; for (const prize of prizes) { currentSum += prize.weight; if (random <= currentSum) { // 奖品库存校验 if (prize.stock = 4 }; // 标记稀有奖品 } } return null;}// 示例奖品池const prizePool = [ { id: 1, name: \'普通玩偶\', weight: 700, stock: 100, rarity: 1 }, { id: 2, name: \'稀有手办\', weight: 250, stock: 10, rarity: 4 }, { id: 3, name: \'SSR卡牌\', weight: 50, stock: 1, rarity: 5 }];

• // 用户抽奖记录表（简化版）class UserDrawHistory { constructor(userId) { this.userId = userId; this.drawCount = 0; this.lastDrawTime = 0; } // 抽奖计数器（30次保底触发稀有奖品） incrementDrawCount() { this.drawCount++; if (this.drawCount >= 30) { // 强制触发保底逻辑 const rarePrize = prizePool.find(p => p.rarity >= 4); if (rarePrize) { this.resetCounter(); return rarePrize; } } return null; } resetCounter() { this.drawCount = 0; }}

  动态奖品池管理（后台可配置奖品类型与库存）

  CREATE TABLE `prize_pool` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(50) NOT NULL COMMENT \'奖品名称\', `type` enum(\'virtual\',\'physical\',\'points\') NOT NULL COMMENT \'奖品类型\', `total_stock` int(11) NOT NULL DEFAULT \'0\' COMMENT \'总库存\', `daily_stock` int(11) DEFAULT \'0\' COMMENT \'每日库存\', `weight` int(11) NOT NULL DEFAULT \'100\' COMMENT \'权重值\', `probability` decimal(5,2) DEFAULT NULL COMMENT \'直接概率（备用）\', `image_url` varchar(255) DEFAULT NULL COMMENT \'奖品图片\', `created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

  // 扣减奖品库存（支持事务）function deductPrizeStock($prizeId, $userId, $quantity = 1) { $pdo = new PDO(\'mysql:host=localhost;dbname=blindbox\', \'user\', \'pass\'); try { $pdo->beginTransaction(); // 1. 检查奖品库存 $stmt = $pdo->prepare(\"SELECT total_stock, daily_stock FROM prize_pool WHERE id = ? FOR UPDATE\"); $stmt->execute([$prizeId]); $prize = $stmt->fetch(PDO::FETCH_ASSOC); if (!$prize || $prize[\'total_stock\'] prepare(\"UPDATE prize_pool SET total_stock = total_stock - ? WHERE id = ?\"); $updateStock->execute([$quantity, $prizeId]); // 3. 记录用户获奖日志 $logStmt = $pdo->prepare(\"INSERT INTO user_prize_log (user_id, prize_id, quantity, draw_time) VALUES (?, ?, ?, NOW())\"); $logStmt->execute([$userId, $prizeId, $quantity]); $pdo->commit(); return true; } catch (Exception $e) { $pdo->rollBack(); error_log(\"库存扣减失败: \" . $e->getMessage()); return false; }}

多端适配架构

• 基于Hybrid混合开发框架（如Uniapp、Taro）实现一次开发多端部署

       {{ prize.name }}  export default { data() { return { isDesktop: false, prize: { /* 奖品数据 */ } } }, onLoad() { // 动态判断设备类型 this.isDesktop = uni.getSystemInfoSync().windowWidth >= 992; }}.container { padding: 20rpx;}.prize-card { width: 100%; margin-bottom: 30rpx;}/* 桌面端适配 */.is-desktop { width: 300px; display: inline-block; margin-right: 20px;}.prize-image { width: 100%; height: 300rpx;}@media (min-width: 992px) { .prize-image { height: 200px; }}

  // 抽奖结果实时推送（前端）let socket;export function initWebSocket(userId) { // 微信小程序环境 if (typeof wx !== \'undefined\') { socket = wx.connectSocket({ url: `wss://yourdomain.com/ws?userId=${userId}`, success: () => console.log(\'WebSocket连接成功\') }); } // H5环境 else if (typeof WebSocket !== \'undefined\') { socket = new WebSocket(`wss://yourdomain.com/ws?userId=${userId}`); } socket.onMessage(e => { const data = JSON.parse(e.data); if (data.type === \'DRAW_RESULT\') { // 更新本地UI updateUserPrizeList(data.payload); } });}// 后端Node.js WebSocket服务示例const WebSocket = require(\'ws\');const wss = new WebSocket.Server({ port: 8080 });wss.on(\'connection\', ws => { const userId = ws.upgradeReq.url.split(\'=\')[1]; console.log(`用户${userId}已连接`); ws.on(\'close\', () => { console.log(`用户${userId}断开连接`); });});// 广播抽奖结果function broadcastDrawResult(userId, prize) { wss.clients.forEach(client => { if (client.readyState === WebSocket.OPEN) { client.send(JSON.stringify({ type: \'DRAW_RESULT\', payload: { userId, prize } })); } });}

• 响应式布局确保Web与移动端UI适配

数据同步与用户体系

• 用户登录态共享（OAuth2.0协议统一鉴权）

  // 微信网页授权跳转export function wechatAuth(appId, redirectUri) { const scope = \'snsapi_userinfo\'; // 静默授权用snsapi_base const state = \'blindbox_\' + Date.now(); // 防CSRF攻击 const authUrl = `https://open.weixin.qq.com/connect/oauth2/authorize? appid=${appId} &redirect_uri=${encodeURIComponent(redirectUri)} &response_type=code &scope=${scope} &state=${state}#wechat_redirect`; window.location.href = authUrl;}// 后端换取access_token（Node.js示例）const axios = require(\'axios\');async function getWechatAccessToken(code) { const url = \'https://api.weixin.qq.com/sns/oauth2/access_token\'; const params = { appid: \'YOUR_APPID\', secret: \'YOUR_APPSECRET\', code: code, grant_type: \'authorization_code\' }; try { const res = await axios.get(url, { params }); // 存储access_token（有效期2小时） cacheAccessToken(res.data.access_token); return res.data; } catch (error) { console.error(\'获取access_token失败:\', error); throw error; }}

• 抽奖记录与资产实时同步（WebSocket长连接）

  // Express.js鉴权中间件const jwt = require(\'jsonwebtoken\');const SECRET_KEY = \'your-256-bit-secret\';function authMiddleware(req, res, next) { const token = req.headers[\'authorization\']?.split(\' \')[1]; if (!token) { return res.status(401).json({ code: 401, message: \'未授权\' }); } try { const decoded = jwt.verify(token, SECRET_KEY); req.userId = decoded.userId; next(); } catch (err) { res.status(403).json({ code: 403, message: \'无效的token\' }); }}// 生成tokenfunction generateToken(userId) { return jwt.sign( { userId, exp: Math.floor(Date.now() / 1000) + 3600 }, SECRET_KEY );}

关键技术实现

跨端通信方案

• 使用postMessage实现H5与原生容器（小程序/APP）的数据交互
• 自定义协议桥接（如jsbridge://action?params）调用原生功能

性能优化策略

• 静态资源懒加载与CDN加速
• 虚拟列表优化长奖品列表渲染

安全防护机制

• 抽奖接口防刷（令牌桶限流+行为验证）

  // 抽奖核心服务（含事务处理）class DrawService { constructor(prizeRepo, userRepo, inventoryService) { this.prizeRepo = prizeRepo; this.userRepo = userRepo; this.inventoryService = inventoryService; } async executeDraw(userId) { const session = await this.userRepo.startSession(); try { session.startTransaction(); // 1. 检查用户状态 const user = await this.userRepo.findById(userId); if (!user || user.isBanned) { throw new Error(\'用户状态异常\'); } // 2. 获取奖品池（带库存锁） const prizePool = await this.prizeRepo.getActivePoolWithLock(); // 3. 执行概率算法（含保底） let prize; const userHistory = await this.userRepo.getDrawHistory(userId); if (userHistory.drawCount >= 29) { // 30次保底 prize = prizePool.find(p => p.rarity >= 4); } else { prize = this.weightedRandomSelect(prizePool); } if (!prize) throw new Error(\'奖品池为空\'); // 4. 扣减库存（分布式锁保障） const success = await this.inventoryService.deductStock( prize.id, 1, { userId, session } ); if (!success) throw new Error(\'库存不足\'); // 5. 记录抽奖结果 await this.userRepo.recordDrawResult(userId, prize.id); // 6. 更新用户资产（如积分/碎片） if (prize.type === \'fragment\') { await this.userRepo.addFragments(userId, prize.fragmentCount); } await session.commitTransaction(); return { success: true, prize }; } catch (error) { await session.abortTransaction(); console.error(\'抽奖失败:\', error); return { success: false, message: error.message }; } finally { session.endSession(); } } weightedRandomSelect(pool) { // 实现同前文权重算法 const total = pool.reduce((sum, p) => sum + p.weight, 0); let rand = Math.random() * total; for (const prize of pool) { if (rand <= prize.weight) return prize; rand -= prize.weight; } return null; }}
