/// note | "기술적 세부사항"

`from starlette.staticfiles import StaticFiles` 를 사용할 수도 있습니다.

**FastAPI**는 단지 개발자인, 당신에게 편의를 제공하기 위해 `fastapi.static files` 와 동일한 `starlett.static files`를 제공합니다. 하지만 사실 이것은 Starlett에서 직접 온 것입니다.

### "마운팅" 이란

"마운팅"은 특정 경로에 완전히 "독립적인" 애플리케이션을 추가하는 것을 의미하는데, 그 후 모든 하위 경로에 대해서도 적용됩니다.

* You don't have to use `File()` in the default value of the parameter.
* It uses a "spooled" file:
    * A file stored in memory up to a maximum size limit, and after passing this limit it will be stored in disk.
* This means that it will work well for large files like images, videos, large binaries, etc. without consuming all the memory.
* You can get metadata from the uploaded file.

# Static Files

You can serve static files automatically from a directory using `StaticFiles`.

## Use `StaticFiles`

* Import `StaticFiles`.
* "Mount" a `StaticFiles()` instance in a specific path.

{* ../../docs_src/static_files/tutorial001.py hl[2,6] *}

/// note | "Technical Details"

You could also use `from starlette.staticfiles import StaticFiles`.

# Request Forms and Files

You can define files and form fields at the same time using `File` and `Form`.

/// info

To receive uploaded files and/or form data, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console

		t.Fatalf("Unable to create a file \"as-file\", %s", err)
	}
	if err = xlStorage.AppendFile(context.Background(), "exists", "as-file-parent/xl.meta", xlMeta); err != nil {
		t.Fatalf("Unable to create a file \"as-file-parent\", %s", err)
	}
	if err = xlStorage.MakeVol(context.Background(), "exists/as-file/"+fi.DataDir); err != nil {

# 请求文件

`File` 用于定义客户端的上传文件。

/// info | "说明"

因为上传文件以「表单数据」形式发送。

所以接收上传文件，要预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如： `pip install python-multipart`。

## 导入 `File`

从 `fastapi` 导入 `File` 和 `UploadFile`：

```Python hl_lines="1"
{!../../docs_src/request_files/tutorial001.py!}
```

## 定义 `File` 参数
