*path operationデコレータ*を設定するためのパラメータがいくつかあります。

!!! warning "注意"
    これらのパラメータは*path operation関数*ではなく、*path operationデコレータ*に直接渡されることに注意してください。

## レスポンスステータスコード

*path operation*のレスポンスで使用する（HTTP）`status_code`を定義することができます。

`404`のように`int`のコードを直接渡すことができます。

しかし、それぞれの番号コードが何のためのものか覚えていない場合は、`status`のショートカット定数を使用することができます:

```Python hl_lines="3  17"
{!../../../docs_src/path_operation_configuration/tutorial001.py!}
```

        br.addItem("Advice");
        br.addElement("Against for JVN14876762.");
        br.addElement("Boundary size is limited by Framework.");
        br.addElement("Too long boundary is treated as 404 because it's thought of as attack.");
        br.addElement("");
        br.addElement("While, you can override the boundary limit size");
        br.addElement(" in " + FessMultipartRequestHandler.class.getSimpleName() + ".");
