Isso não seria tão importante neste exemplo específico porque é um arquivo falso em memória (com `io.BytesIO`), mas com um arquivo real, seria importante garantir que o arquivo fosse fechado ao final do trabalho.

### Arquivos e async { #files-and-async }

Na maioria dos casos, objetos semelhantes a arquivo não são compatíveis com async e await por padrão.

Por exemplo, eles não têm `await file.read()`, nem `async for chunk in file`.

{% endraw %}

...path operation 関数 `read_item(id=id)` が処理するのと同じ URL へのリンクを生成します。

例えば、ID が `42` の場合は次のようにレンダリングされます:

```html
<a href="/items/42">
```

## テンプレートと静的ファイル { #templates-and-static-files }

テンプレート内で `url_for()` を使用し、例えば `name="static"` でマウントした `StaticFiles` に対して利用できます。

```jinja hl_lines="4"
{!../../docs_src/templates/templates/item.html!}
```

この例では、`static/styles.css` の CSS ファイルにリンクします:

		writeErrorResponse(ctx, w, errorCodes.ToAPIErr(ErrEmptyRequestBody), r.URL)
		return
	}

	// Here the parameter is the size of the form data that should
	// be loaded in memory, the remaining being put in temporary files.
	mp, err := multipartReader(r)
	if err != nil {
		apiErr := errorCodes.ToAPIErr(ErrMalformedPOSTRequest)
		apiErr.Description = fmt.Sprintf("%s (%v)", apiErr.Description, err)
		writeErrorResponse(ctx, w, apiErr, r.URL)
