## "Form Alanları" Hakkında

HTML formlarının (`<form></form>`) verileri sunucuya gönderirken JSON'dan farklı özel bir kodlama kullanır.

**FastAPI** bu verilerin JSON yerine doğru şekilde okunmasını sağlayacaktır.

/// note | "Teknik Detaylar"

Form verileri normalde `application/x-www-form-urlencoded` medya tipiyle kodlanır.

<div class="termy">

```console
$ pip install fastapi[all]

---> 100%
```

</div>

... qui comprend également `uvicorn`, que vous pouvez utiliser comme serveur pour exécuter votre code.

/// note

Vous pouvez également l'installer pièce par pièce.

C'est ce que vous feriez probablement une fois que vous voudrez déployer votre application en production :

```
pip install fastapi
```

## Exemplo

Aqui está um exemplo de *operação de rota* com parâmetros utilizando-se de alguns dos tipos acima.

```Python hl_lines="1  3  12-16"
{!../../docs_src/extra_data_types/tutorial001.py!}
```

Note que os parâmetros dentro da função tem seu tipo de dados natural, e você pode, por exemplo, realizar manipulações normais de data, como:

```Python hl_lines="18-19"
{!../../docs_src/extra_data_types/tutorial001.py!}

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

///

## Header Parameters with a Pydantic Model

<div class="termy">

```console
$ pip install "fastapi[all]"

---> 100%
```

</div>

...eso también incluye `uvicorn` que puedes usar como el servidor que ejecuta tu código.

/// note | "Nota"

También puedes instalarlo parte por parte.

Esto es lo que probablemente harías una vez que desees implementar tu aplicación en producción:

```
pip install fastapi
```

/// tip | "Tipp"

Bevorzugen Sie die `Annotated`-Version, falls möglich.

///

```Python hl_lines="7  48  55-56  59-60  69-75"
{!> ../../docs_src/security/tutorial004.py!}
```

/// note | "Hinweis"

Wenn Sie sich die neue (gefakte) Datenbank `fake_users_db` anschauen, sehen Sie, wie das gehashte Passwort jetzt aussieht: `"$2b$12$EixZaYVK1fsbw1ZfbX3OXePaWxn96p36WQoeG6Lruj3vjPGga31lW"`.

`Path`, `Query` 그리고 `Cookie`를 사용한 동일한 구조를 이용하여 헤더 매개변수를 선언합니다.

첫 번째 값은 기본값이며, 추가 검증이나 어노테이션 매개변수 모두 전달할 수 있습니다:

```Python hl_lines="9"

/// note | "기술 세부사항"

`Header`는 `Path`, `Query` 및 `Cookie`의 "자매"클래스입니다. 이 역시 동일한 공통 `Param` 클래스를 상속합니다.

`Query`, `Path`, `Header` 그리고 다른 것들을 `fastapi`에서 임포트 할 때, 이들은 실제로 특별한 클래스를 반환하는 함수임을 기억하세요.
