## 访问模式说明

| 模式 | 适用场景 | 工作原理 |
|------|----------|----------|
| `proxy` | 私有文件、严格权限 | Nginx→Server鉴权→Server从MinIO拉取→返回给用户 |
| `presigned` | 公开分享、大文件 | Server生成预签名URL→用户直连MinIO(经Nginx代理) |
| `cdn` | 静态资源、本地存储 | 返回CDN地址, 用户直接访问 |

**预签名模式配置示例:**
```json
{
  "endpoint": "localhost:9000",
  "bucket": "seeyon-fs",
  "access_key": "admin",
  "secret_key": "123456789",
  "access_mode": "presigned",
  "nginx_endpoint": "http://files.example.com"
}
```
> `nginx_endpoint`: Nginx公网地址, 替换MinIO内部地址, 用户通过Nginx访问MinIO

| local | 本地磁盘 | base_path |
