+# 智店官网
+
+基于 Next.js 16 全栈框架的企业官网项目，当前实现了单页官网展示、联系表单提交、SMTP 邮件通知、可配置 SEO、`robots.txt` / `sitemap.xml` 输出，以及 PM2 生产运行配置。
+
+## 功能概览
+
+- 单页官网：首页内容主要由 `data/*.json` 驱动。
+- 联系表单：提交“获取初步方案”后，会调用 `/api/contact`，由服务端通过 SMTP 发邮件到配置的多个管理邮箱。
+- SEO 配置：站点标题、描述、关键词、canonical、Open Graph、Twitter、站点验证、robots、sitemap 都可配置。
+- 生产部署：支持 `pnpm build && pnpm start`，也提供了 PM2 的 `ecosystem.config.cjs`。
+
+## 快速启动
+
+### 1. 安装依赖
+
+```bash
+pnpm install
+```
+
+### 2. 配置环境变量
+
+本地开发建议使用 `.env.local`。当前项目已经按飞书企业邮箱写入了测试配置。
+
+可参考 `./.env.example`：
+
+```bash
+MAIL_HOST=smtp.feishu.cn
+MAIL_PORT=465
+MAIL_USER=your-mail-account@example.com
+MAIL_PASS=your-mail-password
+MAIL_SSL_ENABLED=true
+MAIL_FROM_EMAIL=your-mail-account@example.com
+MAIL_FROM_NAME=智店软件官网
+```
+
+### 3. 启动开发环境
+
+```bash
+pnpm dev
+```
+
+默认访问：
+
+```text
+http://localhost:3000
+```
+
+## 构建与运行
+
+### 本地生产模式
+
+```bash
+pnpm build
+pnpm start
+```
+
+### 使用 PM2 运行
+
+项目已提供 `./ecosystem.config.cjs`。
+
+```bash
+pnpm build
+pm2 start ecosystem.config.cjs
+pm2 status
+pm2 logs com-index
+```
+
+常用 PM2 命令：
+
+```bash
+pm2 restart com-index
+pm2 stop com-index
+pm2 delete com-index
+pm2 save
+pm2 startup
+```
+
+## 配置说明
+
+### 1. 站点基础配置
+
+文件：`data/site.json`
+
+主要负责：
+
+- 公司名称、英文名、描述、电话、邮箱、地址
+- 顶部导航和页脚导航
+- SEO 全局配置
+
+重点字段：
+
+- `company.phone`：站点展示电话
+- `company.email`：页脚展示邮箱
+- `seo.siteUrl`：线上正式域名，用于 canonical、Open Graph、sitemap、robots
+- `seo.defaultTitle`：默认页面标题
+- `seo.titleTemplate`：子页面标题模板
+- `seo.description`：默认描述
+- `seo.keywords`：关键词数组
+- `seo.canonicalPath`：当前站点 canonical 路径，单页官网一般为 `/`
+- `seo.robots.index` / `seo.robots.follow`：搜索引擎抓取控制
+- `seo.openGraph.image`：社交分享图路径
+- `seo.verification`：搜索引擎站点验证
+
+### 2. 首页文案与区块配置
+
+文件：`data/home.json`
+
+主要负责：
+
+- Hero 文案
+- 产品、方案、案例、联系表单文案
+- “获取初步方案”按钮和联系信息展示
+
+### 3. 邮件通知配置
+
+文件：`config/contact-mailer.yaml`
+
+这个文件负责：
+
+- SMTP 主机、端口、SSL、账号密码引用
+- 发件人邮箱和名称
+- 收件人列表
+- 邮件标题前缀
+
+当前配置方式：
+
+- SMTP 参数优先从 `.env.local` 里的 `MAIL_*` 变量读取
+- `notification.to` 支持配置多个邮箱
+- YAML 里可以直接写死，也可以用 `${ENV_NAME}` / `${ENV_NAME:default}` 引用环境变量
+
+示例：
+
+```yaml
+notification:
+  to:
+    - bd@zhidiansoft.com
+    - ops@zhidiansoft.com
+  subjectPrefix: 官网线索
+```
+
+### 4. SEO 输出文件
+
+文件：
+
+- `app/layout.tsx`
+- `lib/seo.ts`
+- `app/robots.ts`
+- `app/sitemap.ts`
+
+职责：
+
+- `app/layout.tsx`：把 SEO 元数据挂到 Next Metadata
+- `lib/seo.ts`：统一把 `site.json` 里的 SEO 配置转换成 Metadata / robots / sitemap
+- `app/robots.ts`：生成 `/robots.txt`
+- `app/sitemap.ts`：生成 `/sitemap.xml`

+```
+
+## 表单提交流程
+
+1. 用户在“获取初步方案”表单输入姓名、公司、电话、门店规模和需求描述。
+2. 前端组件 `components/sections/contact-section.tsx` 向 `/api/contact` 发起 POST 请求。
+3. API 路由 `app/api/contact/route.ts` 使用 Zod 校验请求体。
+4. 服务端读取 `config/contact-mailer.yaml` 并解析环境变量。
+5. `nodemailer` 通过 SMTP 给 `notification.to` 中的所有邮箱发送通知邮件。
+6. 邮件发送成功后，前端才显示“信息已提交”。
+
+## 注意事项
+
+- `.env.local` 已在 `.gitignore` 中忽略，不会默认提交到仓库。
+- 线上部署前，请确认 `data/site.json` 中的 `seo.siteUrl` 已改成真实域名。
+- 如果邮件发送失败，优先检查 `.env.local`、`contact-mailer.yaml` 和 SMTP 账号权限。
+- 当前仓库存在一些与本次需求无关的历史 TypeScript 报错，`next build` 不受影响，但 `pnpm exec tsc --noEmit` 还不能全绿。
