+# app-api
+
+基于 [Gin](https://github.com/gin-gonic/gin) 的 Go HTTP API 脚手架。
+
+## 项目结构
+
+```
+app-api/
+├── cmd/server/          # 程序入口
+├── internal/
+│   ├── config/          # 配置加载
+│   ├── handler/         # HTTP 处理器
+│   ├── middleware/      # 中间件（日志、CORS、Request ID）
+│   ├── response/        # 统一 JSON 响应
+│   └── router/          # 路由注册
+└── pkg/logger/          # 可复用日志封装
+```
+
+## 快速开始
+
+### 环境要求
+
+- Go 1.22+
+
+### 安装依赖
+
+```bash
+go mod tidy
+```
+
+### 配置（可选）
+
+复制环境变量示例：
+
+```bash
+cp .env.example .env
+```
+
+| 变量 | 默认值 | 说明 |
+|------|--------|------|
+| `APP_ENV` | `development` | 运行环境 |
+| `APP_HOST` | `0.0.0.0` | 监听地址 |
+| `APP_PORT` | `8080` | 监听端口 |
+| `GIN_MODE` | `debug` | Gin 运行模式 |
+
+### 数据库
+
+根据 `APP_ENV` 自动选择 MySQL 配置；也可通过 `DATABASE_*` 环境变量完全覆盖。
+
+| 环境 | `APP_ENV` | 默认连接 |
+|------|-----------|----------|
+| 开发 | `development` | `localhost:3306/audio`，用户 `root`，密码 `root123` |
+| 正式 | `production` | AWS RDS `database-1.chmuueamo72p.eu-central-1.rds.amazonaws.com:3306/audio` |
+
+正式环境密码**必须**通过环境变量 `DATABASE_PASSWORD` 提供（不要写入代码仓库）。可参考 `.env.production.example`。
+
+开发环境可在 `.env` 中覆盖：
+
+```bash
+DATABASE_HOST=localhost
+DATABASE_PORT=3306
+DATABASE_NAME=audio
+DATABASE_USER=root
+DATABASE_PASSWORD=root123
+```
+
+正式环境启动示例（PowerShell）：
+
+```powershell
+$env:APP_ENV = "production"
+$env:DATABASE_PASSWORD = "your-production-password"
+go run ./cmd/server
+```
+
+### 运行
+
+```bash
+make run
+# 或
+go run ./cmd/server
+```
+
+### 健康检查
+
+```bash
+curl http://localhost:8080/api/v1/health
+```
+
+响应示例：
+
+```json
+{
+  "code": 0,
+  "message": "ok",
+  "data": {
+    "status": "up"
+  }
+}
+```
+
+### 品牌列表
+
+```bash
+# 查询全部
+curl "http://localhost:8080/audio/getBrand"
+
+# 按名称模糊查询
+curl "http://localhost:8080/audio/getBrand?brandName=sony"
+```
+
+## 添加新接口
+
+1. 在 `internal/handler/` 新建 handler
+2. 在 `internal/router/router.go` 的 `/api/v1` 分组下注册路由
+3. 使用 `internal/response` 返回统一格式
+
+## 构建
+
+```bash
+make build
+./bin/server
+```
