+# 飞书审批配置服务
+
+内网 Web 服务：用户在浏览器中设计审批表单与流程，保存时**下载包含全部配置的独立 HTML 文件**，可离线打开或分发给他人。
+
+## 功能
+
+- 在线编辑：基础信息、表单设计、流程设计
+- **保存并下载 HTML**：配置写入 HTML 文件，无需本地 bat / data 文件夹
+- **导入 HTML**：继续编辑之前导出的配置文件
+
+## 环境要求
+
+- **Node.js 16.x**（CentOS 7 推荐 16.20 LTS）
+- 无需 `npm install`（零第三方依赖，仅使用 Node 内置模块）
+
+## 快速启动
+
+```bash
+cd Approval_of_design
+node server.js
+```
+
+浏览器访问：`http://服务器IP:8080`
+
+端口与监听地址可在 `project.config.json` 中修改：
+
+```json
+{
+  "projectId": "approval_of_design",
+  "port": 8080,
+  "host": "0.0.0.0",
+  "label": "飞书审批配置服务"
+}
+```
+
+## CentOS 7 部署
+
+### 1. 安装 Node.js 16.x
+
+CentOS 7 自带 glibc 较旧，建议使用 NodeSource 16.x 或 nvm：
+
+**方式 A：NodeSource（推荐）**
+
+```bash
+curl -fsSL https://rpm.nodesource.com/setup_16.x | sudo bash -
+sudo yum install -y nodejs
+node -v   # 应显示 v16.x.x
+```
+
+**方式 B：nvm**
+
+```bash
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
+source ~/.bashrc
+nvm install 16
+nvm use 16
+```
+
+### 2. 上传并启动
+
+```bash
+sudo mkdir -p /opt/feishu-approval
+# 将项目文件上传到 /opt/feishu-approval
+cd /opt/feishu-approval
+node server.js
+```
+
+或使用项目自带脚本：
+
+```bash
+chmod +x deploy/start.sh
+./deploy/start.sh
+```
+
+### 3. systemd 开机自启（推荐）
+
+```bash
+# 修改 deploy/feishu-approval.service 中 WorkingDirectory、User 后：
+sudo cp deploy/feishu-approval.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable feishu-approval
+sudo systemctl start feishu-approval
+sudo systemctl status feishu-approval
+```
+
+### 4. 防火墙
+
+```bash
+sudo firewall-cmd --permanent --add-port=8080/tcp
+sudo firewall-cmd --reload
+```
+
+### 5. 验证
+
+```bash
+curl http://127.0.0.1:8080/api/health
+```
+
+## 部署到其他环境
+
+### 1. 上传项目
+
+将整个 `Approval_of_design` 目录复制到内网服务器。
+
+### 2. 启动服务
+
+**方式 A：直接运行**
+
+```bash
+node server.js
+```
+
+**方式 B：使用 pm2 守护进程（推荐）**
+
+```bash
+npm install -g pm2
+pm2 start server.js --name feishu-approval
+pm2 save
+pm2 startup
+```
+
+**方式 C：Windows 服务**
+
+使用 [nssm](https://nssm.cc/) 将 `node server.js` 注册为 Windows 服务，开机自启。
+
+### 3. 反向代理（可选）
+
+若需通过 80 端口或 HTTPS 访问，可在 Nginx 中配置：
+
+```nginx
+location / {
+    proxy_pass http://127.0.0.1:8080;
+    proxy_http_version 1.1;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+}
+```
+
+### 4. 防火墙
+
+在内网服务器开放 `project.config.json` 中配置的端口（默认 8080）。
+
+## API
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| GET | `/` | 在线编辑器 |
+| GET | `/api/health` | 健康检查 |
+| POST | `/api/export` | 提交 JSON 配置，返回 HTML 文件下载 |
+| POST | `/api/import` | 提交 HTML 文本，解析其中的配置 JSON |
+
+## 文件说明
+
+| 文件 | 说明 |
+|------|------|
+| `server.js` | Web 服务主程序 |
+| `飞书审批配置文件_V1.0.html` | 编辑器模板（服务与导出共用） |
+| `project.config.json` | 端口、服务名称等配置 |
+| `deploy/start.sh` | CentOS 7 启动脚本 |
+| `deploy/feishu-approval.service` | systemd 服务单元示例 |
+
+## 使用流程
+
+1. 访问服务地址，开始新建或导入已有 HTML
+2. 完成表单与流程设计
+3. 点击 **「保存并下载 HTML」**，获得独立配置文件
+4. 下载的 HTML 可双击离线打开；再次编辑可导入回在线服务
+
+## 健康检查
+
+```bash
+curl http://localhost:8080/api/health
+```
