## Завантаження кількох файлів { #multiple-file-uploads }

Можна завантажувати кілька файлів одночасно.

Вони будуть пов’язані з одним і тим самим «form field», який передається у вигляді «form data».

## 可選的檔案上傳 { #optional-file-upload }

可透過一般型別註解並將預設值設為 `None` 使檔案成為可選：

{* ../../docs_src/request_files/tutorial001_02_an_py310.py hl[9,17] *}

## `UploadFile` 搭配額外中繼資料 { #uploadfile-with-additional-metadata }

你也可以在 `UploadFile` 上搭配 `File()`，例如用來設定額外的中繼資料：

{* ../../docs_src/request_files/tutorial001_03_an_py310.py hl[9,15] *}

## 多檔案上傳 { #multiple-file-uploads }

可以同時上傳多個檔案。

 * Form for uploading protected words files to the Fess search engine.
 * Protected words are terms that should not be stemmed or modified during text analysis.
 * This form is used in the admin interface to upload custom protected words dictionary files.

     * The dictionary ID that identifies which protected words dictionary configuration to update.

        return redirect(getClass());

## Téléverser plusieurs fichiers { #multiple-file-uploads }

Il est possible de téléverser plusieurs fichiers en même temps.

Ils seraient associés au même « champ de formulaire » envoyé en « données de formulaire ».

También puedes usar `File()` con `UploadFile`, por ejemplo, para establecer metadatos adicionales:

{* ../../docs_src/request_files/tutorial001_03_an_py310.py hl[9,15] *}

## Subidas de Múltiples Archivos { #multiple-file-uploads }

Es posible subir varios archivos al mismo tiempo.

Estarían asociados al mismo "campo de formulario" enviado usando "form data".

Para usar eso, declara una `list` de `bytes` o `UploadFile`:
