+现在想要开发一个web版本的xshell工具，功能模仿xshell，但是要集成注册和登录 + + +一、 用户与权限系统 (User Center) +这是最基础的门槛，确保数据隔离。 + +P0 - 注册与登录 + +用户注册（邮箱/手机号 + 密码）。 + +用户登录（JWT 或 Session 鉴权）。 + +密码找回/重置。 + +二、 资产管理 (Asset Management) +模仿 Xshell 左侧的“会话管理器”。 + +P0 - 服务器（会话）增删改查 + +添加服务器：主机名 (Name)、IP、端口 (Port)、用户名 (User)。 + +认证方式选择：密码认证、私钥 (PEM/PPK) 认证。 + +核心安全需求：所有密码和私钥在数据库中必须加密存储（使用 AES-256，密钥与用户 ID 绑定），绝不能明文存储。 + +P1 - 分组管理 (Tree View) + +支持文件夹层级结构（类似 Xshell 左侧树状图）。 + +支持拖拽排序、归类。 + +P1 - 快速连接 + +不保存会话，直接输入 ssh user@ip 进行一次性连接。 + +三、 核心终端功能 (Terminal Core) +这是模仿 Xshell 体验的重中之重，前端通常使用 xterm.js，后端使用 SSH2 库。 + +P0 - SSH 连接与交互 + +基于 WebSocket 实现全双工通信。 + +支持标准的 Shell 操作（输入命令、回显、Ctrl+C 中断等）。 + +支持 Vim/Top 等全屏应用的正确渲染。 + +P0 - 终端自适应 (Resize) + +浏览器窗口大小改变时，自动同步发送 window-change 信号给后端，防止 Vim 错位。 + +P1 - 复制粘贴 + +选中文本自动复制（模仿 Xshell 行为）。 + +右键菜单粘贴，或 Shift+Insert 粘贴。 + +P1 - 多标签页 (Tabs) + +支持同时打开多个 SSH 会话，顶部 Tab 切换。 + +支持分屏显示（Split View，左右或上下分屏）。 + +P2 - 外观定制 + +字号调整、字体设置（如 Fira Code）。 + +配色方案切换（黑客绿、Solarized、Monokai 等）。 + +四、 文件传输 (SFTP) +Xshell 通常配合 Xftp 使用，Web 版需要集成轻量级文件管理。 + +P1 - 侧边栏文件树 + +在终端侧边展示当前目录的文件列表。 + +支持双击进入目录、返回上级。 + +P1 - 上传/下载 + +上传：支持拖拽本地文件到浏览器窗口，自动上传到当前目录。 + +下载：右键文件 -> 下载。 + +P2 - 在线编辑 + +双击文本文件，弹窗进行代码编辑，保存后自动上传覆盖（通过 SFTP 协议）。 + +五、 高级辅助功能 (Advanced Features) +这是让你的工具“像 Xshell”的关键。 + +P1 - 保持连接 (Keep-Alive) + +发送心跳包，防止防火墙或 Nginx 切断 WebSocket 连接。 + +断线自动重连机制。 + +P2 - 快捷命令 (Snippets) + +侧边栏或底部栏预设常用命令（如 tail -f logs, docker ps）。 + +点击按钮直接发送命令到终端。 + +P2 - 脚本录制与回放 + +记录操作日志（Asciinema 格式），用于审计。 + +推荐技术架构 +为了实现上述需求，建议的技术选型如下： + +前端 (Frontend) + +框架： Vue3。 + +终端组件：xterm.js (业界标准，VS Code 也在用)。 + +UI 库：Ant Design 或 Element Plus (用于布局和表单)。 + +后端 (Backend) + +语言： Node.js (生态好，SSH 库丰富)。 + +SSH 库： + +Go: golang.org/x/crypto/ssh + +Node.js: ssh2 + +WebSocket： + +Node.js: socket.io 或 ws +
