+# [萌芽妙妙工具]RandBG API：一个零成本、可自托管的随机背景图片API
+
+> **开源地址**:  [github.com/shumengya/randbg-api](https://github.com/shumengya/randbg-api)  
+> **开源协议**:  [MIT License](https://github.com/shumengya/randbg-api/blob/main/LICENSE)  
+> **在线体验**:  [randbg.smyhub.com](https://randbg.smyhub.com)
+> **作者**: *树萌芽*
+
+---
+
+## 前言
+
+平时写博客、做落地页，总需要随机背景图。用别人的服务怕挂、怕限速；自己搭又嫌重。我想要一个**够轻、够快、够便宜**的方案——最好不用维护服务器，直接部署就能跑。
+
+Cloudflare Workers 的 Free Tier 每月 10 万次请求，对个人项目完全够用。问题是：图片放哪儿？
+
+直接把图片塞进 Worker 脚本？不行，Worker 有 4 MiB 体积限制，几十张图直接撑爆。
+
+所以我把架构拆成两层：Worker 只跑 API 逻辑，图片和前端页面全部走 **Workers Static Assets**。
+
+---
+
+## 项目架构
+
+```
+┌─────────────┐     ┌──────────────────┐     ┌──────────────┐
+│   用户请求   │────▶│ Cloudflare Worker│────▶│ Static Assets│
+│             │     │   /api/random    │     │  WebP 图片   │
+└─────────────┘     └──────────────────┘     └──────────────┘
+```
+
+**Worker 端**：不到 200 行 JS，只做三件事——读 `manifest.json`、识别设备、302 或 JSON 响应。
+
+**静态端**：`public/` 目录下放 `index.html`、`manifest.json`、编号 WebP 图片。`wrangler deploy` 一次把前后端一起发布。
+
+这样做的好处很直接：
+- Worker 脚本极小，冷启动几乎无感
+- 图片走 Cloudflare CDN，全球缓存
+- 不涉及数据库，无状态，不存在宕机
+
+---
+
+## 核心功能
+
+### 设备识别
+
+根据 `User-Agent` 和 `Sec-CH-UA-Mobile` 自动判断移动端/桌面端，返回对应方向的图片。你也可以手动指定：
+
+```bash
+curl https://randbg.smyhub.com/api/random?mode=mobile
+```
+
+### 响应格式
+
+默认 `302 Redirect` 直接跳转到图片地址，浏览器里一行就能用：
+
+```html
+<img src="https://randbg.smyhub.com/api/random" />
+```
+
+加上 `?format=json` 返回元数据，方便前端自己控制加载逻辑：
+
+```json
+{
+  "variant": "desktop",
+  "folder": "desketop-image",
+  "filename": "7.webp",
+  "url": "https://randbg.smyhub.com/desketop-image/7.webp",
+  "count": 19
+}
+```
+
+### 构建流程
+
+写了个 `build.py`，功能单一但够用：
+
+1. 扫描 `mobile-image/` 和 `desketop-image/` 目录
+2. 用 Pillow 把原图转为编号 WebP（`1.webp`、`2.webp`...）
+3. 输出到 `public/` 并生成 `manifest.json`
+4. 如果已有 WebP 且没有原图，自动保留，不会误删
+
+```bash
+python3 build.py
+npm run deploy
+```
+
+---
+
+## 部署
+
+整个部署流程是：
+
+1. 把原图扔进 `mobile-image/` 和 `desketop-image/`
+2. `python3 build.py` 转 WebP
+3. `npm run deploy` 推到 Cloudflare
+
+从改图到上线，本地测试用 `npm run dev`，本地 8787 端口就能跑。没有 Docker，没有数据库，没有环境变量要填。
+
+---
+
+如果你也需要一个零成本、不用维护的随机背景服务，可以直接 Fork 用。代码量很小，改起来不费劲。

+   ```bash
+   git commit -m "feat: 添加 xxx 功能"
+   ```
+6. **推送并创建 PR**：推送到你的 Fork 仓库，然后向本仓库提交 Pull Request
+
+## 代码规范
+
+- **JavaScript**：使用 ES Module，保持简洁，添加必要的 JSDoc 注释
+- **Python**：遵循 PEP 8 规范，使用类型注解（如有）
+- **Git 提交信息**：参考 [Conventional Commits](https://www.conventionalcommits.org/)
+  - `feat:` 新功能
+  - `fix:` 修复 Bug
+  - `docs:` 文档更新
+  - `refactor:` 代码重构

+
+---
+
+## 部署指南
+
+### 前置条件
+
+- [Cloudflare 账号](https://dash.cloudflare.com/)
+- [Node.js](https://nodejs.org/) 18+
+- [Python 3](https://python.org/) 3.9+
+- [Wrangler CLI](https://developers.cloudflare.com/workers/wrangler/install-and-update/)
+
+### 1. 克隆项目
+
+```bash
+git clone https://github.com/shumengya/randbg-api.git
+cd randbg-api
+```
+
+### 2. 安装依赖
+
+```bash
+npm install
+```
+
+### 3. 准备图片
+
+将原始图片放入对应目录：
+
+```
+mobile-image/        # 竖屏图片（移动端）
+desketop-image/      # 横屏图片（桌面端）
+```
+
+支持格式：`.jpg` `.jpeg` `.png` `.bmp` `.gif` `.tif` `.tiff` `.webp`
+
+### 4. 构建 WebP 与清单
+
+```bash
+python3 build.py
+```
+
+脚本会自动完成以下工作：
+1. 将原图转换为高质量编号 WebP（`1.webp` `2.webp` ...）
+2. 生成 `public/manifest.json`
+3. 将转换后的文件输出到 `public/` 部署目录
+
+如果 `public/` 下已有序号 WebP 且没有原图，脚本会**保留现有文件**，不会误删。
+
+### 5. 本地预览
+
+```bash
+npm run dev
+```
+
+默认在 `http://localhost:8787` 启动预览。
+
+### 6. 部署到 Cloudflare
+
+```bash
+npm run deploy
+```
+
+Wrangler 会将 `src/worker.js` 打包为 Worker，同时将 `public/` 作为静态 Assets 一起发布。
+
+---
 
 ## 目录约定
 
-- `mobile-image/`：竖屏图片原图上传目录
-- `desketop-image/`：横屏图片原图上传目录
+- **`public/mobile-image/`**：竖屏图片（移动端）
+- **`public/desketop-image/`**：横屏图片（桌面端）
+  - 注意拼写沿用历史目录名，API 内部已兼容
+- **`public/manifest.json`**：构建产物，API 运行时通过内部请求读取该清单
 
-## 使用流程
+---
 
-1. 把图片上传到对应目录。
-2. 运行构建脚本：
-   ```bash
-   python3 build.py
-   ```
-3. 把项目根目录作为 Cloudflare Pages 的发布目录部署。
-4. 打开：
-   - 页面：`/`
-   - API：`/api/random`
+## 注意事项
 
-## API
+1. **原图不上传**：根目录下的 `mobile-image/` 和 `desketop-image/` 仅用于本地构建，已配置 `.gitignore` 避免误提交。GitHub 仓库中只保留构建后的 `public/` 资源。
+2. **图片版权**：请确保上传的图片拥有合法使用权或来自版权友好的来源。
+3. **Worker 体积限制**：静态资源通过 Cloudflare Assets 提供，不占用 Worker 脚本 4 MiB 限制，可放心使用大量图片。
+4. **缓存策略**：`public/_headers` 已为图片配置了 `immutable` 长期缓存，为 `manifest.json` 配置了 5 分钟缓存。如需更新图片，请重新运行 `build.py` 并部署。
 
-- `GET /api/random`
-  - 默认按 `mode=auto` 随机返回图片重定向
-- `GET /api/random?format=json`
-  - 返回 JSON
-- `GET /api/list`
-  - 返回图片清单

-## 组件嵌入

-  mode="auto"

-  radius="16px"
-  height="260px">

-```
+本项目基于 [MIT License](LICENSE) 开源。
 
-`widget.js` 只读取静态的 `manifest.json` 和图片文件，不会调用 `api/random`。
+---
 
-## 构建说明
+## 贡献
 
-`build.py` 会把目录里的原图转换成同目录下的编号 `webp` 文件，例如：
+欢迎提交 Issue 和 Pull Request！如果你有任何建议或发现问题，请随时反馈。
 
-- `1.webp`
-- `2.webp`
-- `55.webp`
+---
 
-同时生成 `manifest.json`，供 Pages Functions 读取。
