From 678d750c8a6c4f7a15fd9a1a63ab288fdd96dc44 Mon Sep 17 00:00:00 2001 From: ZacharyZcR Date: Mon, 25 Aug 2025 23:57:00 +0800 Subject: [PATCH] =?UTF-8?q?refactor:=20=E9=87=8D=E6=9E=84=E6=8F=92?= =?UTF-8?q?=E4=BB=B6=E6=9E=B6=E6=9E=84=EF=BC=8C=E5=AE=9E=E7=8E=B0=E5=8D=95?= =?UTF-8?q?=E6=96=87=E4=BB=B6=E6=8F=92=E4=BB=B6=E7=B3=BB=E7=BB=9F?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 将复杂的三文件插件架构(connector/exploiter/plugin)重构为简化的单文件插件架构， 大幅减少代码重复和维护成本，提升插件开发效率。 主要改进: • 将每个服务插件从3个文件简化为1个文件 • 删除过度设计的工厂模式、适配器模式等抽象层 • 消除plugins/services/、plugins/adapters/、plugins/base/复杂目录结构 • 实现直接的插件注册机制，提升系统简洁性 • 保持完全向后兼容，所有扫描功能和输出格式不变 重构统计: • 删除文件：100+个复杂架构文件 • 新增文件：20个简化的单文件插件 • 代码减少：每个插件减少60-80%代码量 • 功能增强：所有插件包含完整扫描和利用功能 已重构插件: MySQL, SSH, Redis, MongoDB, PostgreSQL, MSSQL, Oracle, Neo4j, Memcached, RabbitMQ, ActiveMQ, Cassandra, FTP, Kafka, LDAP, Rsync, SMTP, SNMP, Telnet, VNC 验证通过: 新系统编译运行正常，所有插件功能验证通过 ---
