## Про "поля форми"

HTML-форми (`<form></form>`) надсилають дані на сервер у "спеціальному" кодуванні, яке відрізняється від JSON.

**FastAPI** подбає про те, щоб зчитати ці дані з правильного місця, а не з JSON.

/// note | Технічні деталі

Дані з форм зазвичай кодуються за допомогою "типу медіа" `application/x-www-form-urlencoded`.

But even if you **fill the data** and click "Execute", because the docs UI works with **JavaScript**, the cookies won't be sent, and you will see an **error** message as if you didn't write any values.

## Forbid Extra Cookies { #forbid-extra-cookies }

In some special use cases (probably not very common), you might want to **restrict** the cookies that you want to receive.

## Forbid Extra Query Parameters { #forbid-extra-query-parameters }

In some special use cases (probably not very common), you might want to **restrict** the query parameters that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/query_param_models/tutorial002_an_py310.py hl[10] *}

   * return type is plain FilenameFilter. If we made such a change, then the annotation we choose
   * here would have no significance to end users, who would be forced to conform to the signature
   * used in FilenameFilter.)

## Как запретить дополнительные заголовки { #forbid-extra-headers }

В некоторых случаях (не особо часто встречающихся) вам может понадобиться **ограничить** заголовки, которые вы хотите получать.

Вы можете использовать возможности конфигурации Pydantic-модели для того, чтобы запретить (`forbid`) любые дополнительные (`extra`) поля:

## Proibindo Cabeçalhos adicionais { #forbid-extra-headers }

Em alguns casos de uso especiais (provavelmente não muito comuns), você pode querer **restringir** os cabeçalhos que você quer receber.

Você pode usar a configuração dos modelos do Pydantic para proibir (`forbid`) quaisquer campos `extra`:

{* ../../docs_src/header_param_models/tutorial002_an_py310.py hl[10] *}
