From 6c93129cb111fd51b66c35730c09a5b689c9250e Mon Sep 17 00:00:00 2001 From: ZacharyZcR Date: Thu, 7 Aug 2025 09:13:17 +0800 Subject: [PATCH] =?UTF-8?q?refactor:=20=E9=87=8D=E6=9E=84=E6=89=AB?= =?UTF-8?q?=E6=8F=8F=E5=99=A8=E6=9E=B6=E6=9E=84=E4=BC=98=E5=8C=96=E4=BB=A3?= =?UTF-8?q?=E7=A0=81=E5=A4=8D=E7=94=A8=E5=92=8C=E6=80=A7=E8=83=BD?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 主要改进： - 创建BaseScanStrategy基础类提取通用功能，减少60%代码重复 - 新增PortDiscoveryService分离端口发现逻辑，提升职责清晰度 - 优化插件匹配算法，从O(n×m×p)降至O(n×p)复杂度 - 修复插件适用性判断逻辑错误，确保精确端口匹配 - 完善国际化支持，新增21个i18n消息定义 - 代码行数显著减少：LocalScanner(-50%)、ServiceScanner(-42%)、WebScanner(-44%) 技术优化： - 组合模式替代继承，提升扩展性 - 策略模式实现插件过滤器，支持Local/Service/Web类型 - 服务分离提升可测试性和维护性 - 性能优化减少嵌套循环和重复计算 确保漏洞扫描插件列表与实际执行插件保持精确一致。 ---
