-# SimpleNav
+# SimpleNav · 简航
-简航，一个面向个人的轻量级导航系统
\ No newline at end of file
+简航（SimpleNav），一个面向个人的**轻量级网站导航系统**。PHP + SQLite，零外部依赖、无需 Composer，上传即用。
+
+## 特点
+
+- **轻量**：纯 PHP + SQLite，不依赖 MySQL / 框架 / Composer；前端无 Bootstrap / jQuery，原生 CSS + JS。
+- **个人向**：单管理员，页面就是「你自己常用网站的起始页」。
+- **搜索引擎可切换 + 联想下拉**：后台勾选喜欢的搜索引擎即可显示在顶部；输入时下拉联想词由服务端代理（规避跨域）。
+- **添加即补全**：填网址自动抓取网站名称、图标（图标下载并规范化后存到服务器本地）。
+- **显示简称**：每个网站有「名称（自动）」和「简称（手动）」两个字段，页面展示你自定义的简称。
+- **自定义排序**：网站 / 板块 / 搜索引擎都可上移下移排序。
+- **一键全部更新**：批量刷新所有网站的图标与名称，**不会改动你自定义的简称**。
+- **合集标签页**：把「合集」做成标签页，点标签平铺该合集下的全部链接。
+
+## 页面结构（复刻 n.yangyq.net 风格）
+
+1. 顶部：搜索引擎切换 + 搜索框（带联想下拉）
+2. 中部：网格板块（如「常用」「工具」）
+3. 下部：「合集」标签页
+
+## 目录结构
+
+```
+SimpleNav/
+├─ index.php 前台首页
+├─ suggest.php 搜索联想代理（多引擎，服务端请求）
+├─ login.php / logout.php 管理员登录 / 首次初始化
+├─ db.php 数据库初始化（建表 + 默认数据）
+├─ config.php 基础配置
+├─ functions.php 公共函数（抓取元信息、下载图标等）
+├─ admin/ 后台（网站 / 板块 / 搜索引擎 / 设置）
+│ ├─ index.php 后台页面
+│ ├─ actions.php 增删改 / 排序处理
+│ ├─ fetch_meta.php 添加网站时自动抓取名称与图标
+│ └─ update_all.php 一键“全部更新”（分批）
+├─ assets/ CSS / JS / 图标
+├─ uploads/icons/ 抓取到的网站图标（需可写）
+└─ data/ SQLite 数据库（需可写，禁止 Web 访问）
+```
+
+## 部署
+
+1. 上传全部文件到站点目录（如 `/www/wwwroot/n.yangyq.net/simplenav`）。
+2. 确保 web 用户对 `data/` 与 `uploads/icons/` 有写权限。
+3. 浏览器打开站点 → 首次访问进入「初始化管理员」，创建账号后即可在后台管理。
+4. 建议在 nginx server{} 中加入 `deploy/nginx-simplenav-deny-data.conf` 里的规则（禁止访问 `data/`）。
+
+服务器上创建最小权限部署账号：以 root 运行 `deploy/setup-simplenav-user.sh`。
+
+## 搜索引擎联想接口说明
+
+联想接口需服务端代理（浏览器直接调用会跨域）。内置解析类型：
+
+| 类型 | 平台 | 联想接口 |
+|---|---|---|
+| `bing_osjson` | 必应 | `https://api.bing.com/osjson.aspx?query={q}` |
+| `baidu_sugrec` | 百度 | `https://www.baidu.com/sugrec?prod=pc&wd={q}` |
+| `google_firefox` | 谷歌 | `https://suggestqueries.google.com/complete/search?client=firefox&q={q}` |
+| `sogou_ajaj` | 搜狗 | `https://www.sogou.com/suggnew/ajajjson?type=web&key={q}` |
+| `so360` | 360 | `https://sug.so.360.cn/suggest?encodein=utf-8&encodeout=utf-8&format=json&word={q}` |
+| `ddg` | DuckDuckGo | `https://duckduckgo.com/ac/?type=list&q={q}` |
+
+> 注：国内服务器访问 Google / DuckDuckGo 可能不通，联想会优雅降级为空（不影响搜索跳转）。
