## `TrustedHostMiddleware`

Garante que todas as requisições recebidas tenham um cabeçalho `Host` corretamente configurado, a fim de proteger contra ataques de cabeçalho de host HTTP.

{* ../../docs_src/advanced_middleware/tutorial002.py hl[2,6:8] *}

Os seguintes argumentos são suportados:

생성된 JSON 스키마에 추가될 Pydantic 모델을 위한 `examples`을 선언할 수 있습니다.

//// tab | Pydantic v2

//// tab | Pydantic v1

{* ../../docs_src/schema_extra_example/tutorial001_pv1_py310.py hl[13:23] *}

추가 정보는 있는 그대로 해당 모델의 **JSON 스키마** 결과에 추가되고, API 문서에서 사용합니다.

クッキーのパラメータは、`Query`や`Path`のパラメータを定義するのと同じ方法で定義できます。

## `Cookie`をインポート

まず、`Cookie`をインポートします:

{* ../../docs_src/cookie_params/tutorial001.py hl[3] *}

## `Cookie`のパラメータを宣言

次に、`Path`や`Query`と同じ構造を使ってクッキーのパラメータを宣言します。

最初の値がデフォルト値で、追加の検証パラメータや注釈パラメータをすべて渡すことができます:

{* ../../docs_src/cookie_params/tutorial001.py hl[9] *}

/// note | 技術詳細

`Cookie`は`Path`と`Query`の「姉妹」クラスです。また、同じ共通の`Param`クラスを継承しています。

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

/// warning | Achtung

Beachten Sie, dass `Field` direkt von `pydantic` importiert wird, nicht von `fastapi`, wie die anderen (`Query`, `Path`, `Body`, usw.)

///

## Modellattribute deklarieren

Dann können Sie `Field` mit Modellattributen deklarieren:

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

{* ../../docs_src/extra_models/tutorial002.py hl[9,15,16,19,20,23,24] *}

## `Union`または`anyOf`

レスポンスを２つの型の`Union`として宣言することができます。

OpenAPIでは`anyOf`で定義されます。

そのためには、標準的なPythonの型ヒント<a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>を使用します:

{* ../../docs_src/extra_models/tutorial003.py hl[1,14,15,18,19,20,33] *}

## モデルのリスト

### `OAuth2PasswordRequestForm`

Primeiro, importe `OAuth2PasswordRequestForm` e use-o como uma dependência com `Depends` na *operação de rota* para `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` é uma dependência de classe que declara um corpo de formulário com:

* O `username`.
* A `password`.

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies).

And then you can set headers in that *temporal* response object.

{* ../../docs_src/response_headers/tutorial002.py hl[1, 7:8] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

`Form` sınıfını `fastapi`'den projenize dahil edin:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[3] *}

## `Form` Parametrelerini Tanımlayın

Form parametrelerini `Body` veya `Query` için yaptığınız gibi oluşturun:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[9] *}

{* ../../docs_src/extra_data_types/tutorial001.py hl[1,3,12:16] *}

Обратите внимание, что параметры внутри функции имеют свой естественный тип данных, и вы, например, можете выполнять обычные манипуляции с датами, такие как:

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

### Declare the dependency, in the "dependant" { #declare-the-dependency-in-the-dependant }

The same way you use `Body`, `Query`, etc. with your *path operation function* parameters, use `Depends` with a new parameter:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}
