# 메타데이터 및 문서화 URL

**FastAPI** 응용 프로그램에서 다양한 메타데이터 구성을 사용자 맞춤 설정할 수 있습니다.

## API에 대한 메타데이터

OpenAPI 명세 및 자동화된 API 문서 UI에 사용되는 다음 필드를 설정할 수 있습니다:

| 매개변수 | 타입 | 설명 |
|----------|------|-------|
| `title` | `str` | API의 제목입니다. |
| `summary` | `str` | API에 대한 짧은 요약입니다. <small>OpenAPI 3.1.0, FastAPI 0.99.0부터 사용 가능</small> |
| `description` | `str` | API에 대한 짧은 설명입니다. 마크다운을 사용할 수 있습니다. |

/// note | "技术细节"

你也可以用 `from starlette.staticfiles import StaticFiles`。

**FastAPI** 提供了和 `starlette.staticfiles` 相同的 `fastapi.staticfiles` ，只是为了方便你，开发者。但它确实来自Starlette。

### 什么是"挂载"(Mounting)

"挂载" 表示在特定路径添加一个完全"独立的"应用，然后负责处理所有子路径。

这与使用`APIRouter`不同，因为安装的应用程序是完全独立的。OpenAPI和来自你主应用的文档不会包含已挂载应用的任何东西等等。
