## Was sind „Formulardaten“ { #what-is-form-data }

Der Weg, wie HTML-Formulare (`<form></form>`) die Daten zum Server senden, verwendet normalerweise eine „spezielle“ Kodierung für diese Daten. Diese unterscheidet sich von JSON.

<div>
	<fieldset class="mb-3">
		<legend><la:message key="labels.index_num" /></legend>
		<label for="numSearchOption"><la:message key="labels.index_num" /></label>
		<la:select property="num" styleId="numSearchOption"
			styleClass="form-control">
			<option value="10">
				<la:message key="labels.search_result_select_num" />
			</option>
			<la:option value="10">10</la:option>
			<la:option value="20">20</la:option>
			<la:option value="30">30</la:option>

Se você passar algo "chamável" como uma dependência do **FastAPI**, o framework irá analisar os parâmetros desse "chamável" e processá-los da mesma forma que os parâmetros de uma *função de operação de rota*. Incluindo as sub-dependências.

Isso também se aplica a objetos chamáveis que não recebem nenhum parâmetro. Da mesma forma que uma *função de operação de rota* sem parâmetros.

* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:

```python
from fastapi import Body, Cookie, File, Form, Header, Path, Query
```

::: fastapi.Query

::: fastapi.Path

::: fastapi.Body

::: fastapi.Cookie

::: fastapi.Header

::: fastapi.Form
