## Объявление атрибутов модели { #declare-model-attributes }

Вы можете использовать функцию `Field` с атрибутами модели:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

Функция `Field` работает так же, как `Query`, `Path` и `Body`, у неё такие же параметры и т.д.

/// note | Технические детали

你可以用與定義 `Query` 與 `Path` 參數相同的方式定義 Cookie 參數。

## 匯入 `Cookie` { #import-cookie }

先匯入 `Cookie`：

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3] *}

## 宣告 `Cookie` 參數 { #declare-cookie-parameters }

然後用與 `Path`、`Query` 相同的結構宣告 `Cookie` 參數。

你可以設定預設值，以及所有額外的驗證或註解參數：

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[9] *}

/// note | 技術細節

## Montando uma aplicação **FastAPI** { #mounting-a-fastapi-application }

"Montar" significa adicionar uma aplicação completamente "independente" em um path específico, que então se encarrega de lidar com tudo sob esse path, com as _operações de rota_ declaradas nessa sub-aplicação.

### Aplicação de nível superior { #top-level-application }

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[157] *}

## Declare scopes in *path operations* and dependencies { #declare-scopes-in-path-operations-and-dependencies }

Now we declare that the *path operation* for `/users/me/items/` requires the scope `items`.

For this, we import and use `Security` from `fastapi`.

            return rel != null ? new SourceWrapper(rel) : null;
        }

        @Override
        public URI getLocationURI() {
            Path path = source.getPath();
            return path != null ? path.toUri() : URI.create(source.getLocation());
        }
    }

## `PATH`-Umgebungsvariable { #path-environment-variable }

Es gibt eine **spezielle** Umgebungsvariable namens **`PATH`**, die von den Betriebssystemen (Linux, macOS, Windows) verwendet wird, um Programme zu finden, die ausgeführt werden sollen.

Asynchronously streams a file as the response.

Takes a different set of arguments to instantiate than the other response types:

* `path` - The file path to the file to stream.
* `headers` - Any custom headers to include, as a dictionary.
* `media_type` - A string giving the media type. If unset, the filename or path will be used to infer a media type.
* `filename` - If set, this will be included in the response `Content-Disposition`.

## Importar `Header` { #import-header }

Primero importa `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Declarar parámetros de `Header` { #declare-header-parameters }

Luego declara los parámetros de header usando la misma estructura que con `Path`, `Query` y `Cookie`.
