# `UploadFile` class

You can define *path operation function* parameters to be of the type `UploadFile` to receive files from the request.

You can import it directly from `fastapi`:

```python
from fastapi import UploadFile
```

::: fastapi.UploadFile
    options:
        members:
            - file
            - filename
            - size
            - headers
            - content_type
            - read

For those cases, you can use a `Response` parameter.

## Use a `Response` parameter { #use-a-response-parameter }

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies and headers).

And then you can set the `status_code` in that *temporal* response object.

相対 URL を使うことは、[プロキシと接続](../../advanced/behind-a-proxy.md){.internal-link target=_blank}のような高度なユースケースでもアプリケーションを動作させ続けるために重要です。

///

このパラメーターはエンドポイント/ *path operation*を作成しません。しかし、URL`/token`はクライアントがトークンを取得するために使用するものであると宣言します。この情報は OpenAPI やインタラクティブな API ドキュメントシステムで使われます。

実際のpath operationもすぐに作ります。

/// info | 情報

非常に厳格な「Pythonista」であれば、パラメーター名のスタイルが`token_url`ではなく`tokenUrl`であることを気に入らないかもしれません。
