⚙️ 系统优化亮点

1. OpenSSL安全验证体系

   • 双重签名验证（客户端请求 + 三方回调）
   • RSA2048算法确保数据完整性
   • 密钥分级管理（支付宝密钥 + 平台密钥）

2. 全面日志监控

   • 四级日志级别（DEBUG/INFO/WARNING/ERROR）
   • 关键操作全链路追踪
   • 敏感数据脱敏记录

3. 多层防风暴机制

   graph TD
   A[客户端请求] --> B{频率限制}
   B -->|允许| C[处理请求]
   B -->|拒绝| D[返回429]
   E[回调通知] --> F{队列锁}
   F -->|不存在| G[入队通知]
   F -->|已存在| H[丢弃请求]
   I[通知处理] --> J{令牌桶}
   J -->|通过| K[发送通知]
   J -->|拒绝| L[延迟重试]
   

4. 队列可靠性保障

   • 指数退避重试策略（5/15/30/60/120秒）
   • 最大尝试次数控制
   • 消息确认机制

5. 智能白名单系统

   • 支持通配符域名（*.trusted.com）
   • IP白名单双重验证
   • 自动识别顶级域名

🚀 部署建议

1. 证书管理

   # 生成RSA密钥
   openssl genrsa -out rsa_private_key.pem 2048
   openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
   

2. 队列服务配置（.env）

   [QUEUE]
   driver = redis
   host = 127.0.0.1
   port = 6379
   password = 
   select = 1
   timeout = 0
