Mais si vous avez spécifié une classe de réponse personnalisée avec `None` comme type de média, FastAPI utilisera `application/json` pour toute réponse supplémentaire associée à un modèle.

## Необязательная загрузка файлов { #optional-file-upload }

Вы можете сделать загрузку файла необязательной, используя стандартные аннотации типов и установив значение по умолчанию `None`:

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

## `UploadFile` с дополнительными метаданными { #uploadfile-with-additional-metadata }

例如，要声明路径参数 `item_id`的 `title` 元数据值，你可以输入：

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note

路径参数总是必需的，因为它必须是路径的一部分。

所以，你应该在声明时使用 `...` 将其标记为必需参数。

然而，即使你使用 `None` 声明路径参数或设置一个其他默认值也不会有任何影响，它依然会是必需参数。

///

## 按需对参数排序

假设你想要声明一个必需的 `str` 类型查询参数 `q`。

而且你不需要为该参数声明任何其他内容，所以实际上你并不需要使用 `Query`。

但是你仍然需要使用 `Path` 来声明路径参数 `item_id`。

Das zweite Argument von <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> ist der Defaultwert, der zurückgegeben wird.

Wenn er nicht angegeben wird, ist er standardmäßig `None`. Hier geben wir `"World"` als den zu verwendenden Defaultwert an.

Dann könnten Sie das Python-Programm aufrufen:

Porém se você especificou uma classe de retorno com o valor `None` como media type, o FastAPI utilizará `application/json` para qualquer retorno adicional que possui um modelo associado.
