## Múltiples parámetros del cuerpo { #multiple-body-parameters }

En el ejemplo anterior, las *path operations* esperarían un cuerpo JSON con los atributos de un `Item`, como:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

Pero también puedes declarar múltiples parámetros del cuerpo, por ejemplo `item` y `user`:

 * <p>
 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism
 * and their provided lifecycles will be available throughout the Maven build process.
 * <p>
 * Example usage:
 * <pre>
 * public class CustomLifecycleProvider implements LifecycleProvider {
 *     public Collection&lt;Lifecycle&gt; provides() {
 *         return Collections.singleton(

 * <p>
 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism
 * and their provided path scopes will be available throughout the Maven build process.
 * <p>
 * Example usage:
 * <pre>
 * public class CustomPathScopeProvider implements PathScopeProvider {
 *     public Collection&lt;PathScope&gt; provides() {
 *         return Collections.singleton(pathScope("integration-test",

 * <p>
 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism
 * and their provided types will be available throughout the Maven build process.
 * <p>
 * Example usage:
 * <pre>
 * public class CustomTypeProvider implements TypeProvider {
 *     public Collection&lt;Type&gt; provides() {
 *         return Arrays.asList(
 *             type("kotlin-library", "jar", "kotlin"),

Porém em alguns casos você precisa retornar um código de status diferente do padrão.

## Caso de uso { #use-case }

Por exemplo, imagine que você deseja retornar um código de status HTTP de "OK" `200` por padrão.

Mas se o dado não existir, você quer criá-lo e retornar um código de status HTTP de "CREATED" `201`.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

```console
$ pip install python-multipart
```

## Importar `Form` { #import-form }

Importar `Form` desde `fastapi`:

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

以下の引数がサポートされています:

* `allow_origins` - オリジン間リクエストを許可するオリジンのリスト。例えば、`['https://example.org', 'https://www.example.org']`。`['*']`を使用して任意のオリジンを許可できます。
* `allow_origin_regex` - オリジン間リクエストを許可するオリジンの正規表現文字列。例えば、`'https://.*\.example\.org'`。
* `allow_methods` - オリジン間リクエストで許可するHTTPメソッドのリスト。デフォルトは `['GET']` です。`['*']`を使用してすべての標準メソッドを許可できます。

Por exemplo, você pode querer experimentar:

* <a href="https://speakeasy.com/editor?utm_source=fastapi+repo&utm_medium=github+sponsorship" class="external-link" target="_blank">Speakeasy</a>

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

```console
$ pip install python-multipart
```
