В этом примере, у нас есть 3 параметра запроса:

* `needy`, обязательный `str`.
* `skip`, типа `int` и со значением по умолчанию `0`.
* `limit`, необязательный `int`.

/// tip | Подсказка

Вы можете использовать класс `Enum` также, как ранее применяли его с [Path-параметрами](path-params.md#_7){.internal-link target=_blank}.

	lineNum       int   // Line number in source file.

	errorCount    int   // Number of errors.
	sawCode       bool  // saw code in this file (as opposed to comments and blank lines)

devido ao parâmetro da rota `item_id` ter um valor `"foo"`, que não é um `int`.

O mesmo erro apareceria se você tivesse fornecido um `float` ao invés de um `int`, como em: <a href="http://127.0.0.1:8000/items/4.2" class="external-link" target="_blank">http://127.0.0.1:8000/items/4.2</a>

Mit `Form` haben Sie die gleichen Konfigurationsmöglichkeiten wie mit `Body` (und `Query`, `Path`, `Cookie`), inklusive Validierung, Beispielen, einem Alias (z. B. `user-name` statt `username`), usw.

/// info

`Form` ist eine Klasse, die direkt von `Body` erbt.
