## 权限标识一览

| 权限标识 | 说明 |
|----------|------|
| file:create | 创建文件/文件夹 |
| file:read | 查看文件 |
| file:update | 修改文件 |
| file:delete | 删除文件 |
| file:upload | 上传文件 |
| file:download | 下载文件 |
| file:grant | 授权文件权限(给其他用户/角色) |
| share:create | 创建分享 |
| share:manage | 管理分享 |
| webdav:access | WebDAV访问 |
| user:manage | 用户管理 |
| role:manage | 角色管理 |
| sso:manage | SSO管理 |
| system:manage | 系统管理 |
| * | 所有权限(超级管理员) |

### 默认角色权限

| 角色 | 权限 |
|------|------|
| admin | *(全部) |
| staff | file:create, file:read, file:update, file:delete, file:upload, file:download, file:grant, share:create, webdav:access |
| user | file:create, file:read, file:update, file:upload, file:download, share:create |
| guest | file:read |

### 文件可见性规则

| 角色 | 可见范围 |
|------|----------|
| admin | 所有文件 |
| 其他角色 | 自己创建的 + fs_file_permission 中被授权的 |

### 文件操作权限规则

文件操作(删除/重命名/移动/下载/授权等)需要同时满足:
1. 用户角色拥有对应权限码(如 `file:delete`)
2. 用户有权操作该具体文件(owner / admin / fs_file_permission 被授权)

### 2.17 统一文件访问(自动选择模式)
```
GET /api/file/:id/access
token: <token>
```
> 根据存储策略的 `access_mode` 自动选择:
> - `proxy`: 中转模式, 直接返回文件流
> - `presigned`: 预签名模式, 302重定向到MinIO
> - `cdn`: CDN模式, 302重定向到CDN地址

### 2.18 获取文件访问URL
```
GET /api/file/:id/access-url
token: <token>
```
**响应:**
```json
{
  "code": 0,
  "data": {
    "mode": "presigned",
    "url": "http://files.example.com/minio/seeyon-fs/2026/07/02/...?X-Amz-...",
    "file_name": "test.pdf",
    "file_size": 1024000,
    "content_type": "application/pdf"
  }
}
```

### 2.19 分享文件统一访问(公开)
```
GET /api/s/:code/access?password=xxx
```

## 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
