* 🐛 Fix parsing extra `Form` parameter list. PR [#14303](https://github.com/fastapi/fastapi/pull/14303) by [@YuriiMotov](https://github.com/YuriiMotov).

    // IPv6 literals.
    HostAndPort parsedHost = HostAndPort.fromString(specifier);
    Preconditions.checkArgument(!parsedHost.hasPort());
    String host = parsedHost.getHost();

    // Try to interpret the specifier as an IP address. Note we build
    // the address rather than using the .is* methods because we want to
    // use InetAddresses.toUriString to convert the result to a string in
    // canonical form.

some_variable: PlaneItem | CarItem
```

Pero si ponemos eso en la asignación `response_model=PlaneItem | CarItem` obtendríamos un error, porque Python intentaría realizar una **operación inválida** entre `PlaneItem` y `CarItem` en lugar de interpretar eso como una anotación de tipos.

## Lista de modelos { #list-of-models }

De la misma manera, puedes declarar responses de listas de objetos.

Para eso, usa la `list` estándar de Python:

private val QUOTED_STRING_DELIMITERS = "\"\\".encodeUtf8()
private val TOKEN_DELIMITERS = "\t ,=".encodeUtf8()

/**
 * Parse RFC 7235 challenges. This is awkward because we need to look ahead to know how to

 * For example, the first line has a parameter name/value pair and the second line has a single
 * token68:
 *
 * ```
 * WWW-Authenticate: Digest foo=bar
 * WWW-Authenticate: Digest foo=

  // Not specifying KNOWN_ORDER for PriorityQueue and PriorityBlockingQueue
  // even though they do have it, because our tests interpret KNOWN_ORDER to

Bien entendu, vous pouvez également déclarer des paramètres de requête supplémentaires quand vous en avez besoin, en plus de tout paramètre du corps de la requête.

Comme, par défaut, les valeurs singulières sont interprétées comme des paramètres de requête, vous n'avez pas besoin d'ajouter explicitement `Query`, vous pouvez simplement écrire :

```Python
q: str | None = None
```

Par exemple :

    override fun coordinatorNotify(taskRunner: TaskRunner) {
      taskRunner.notify()
    }

    /**
     * Wait a duration in nanoseconds. Unlike [java.lang.Object.wait] this interprets 0 as
     * "don't wait" instead of "wait forever".
     */
    @Throws(InterruptedException::class)
    @Suppress("PLATFORM_CLASS_MAPPED_TO_KOTLIN")
    override fun coordinatorWait(
      taskRunner: TaskRunner,

	// flag bit is set. However, there are several problems:
	//
	//	* Many ZIP readers still do not support UTF-8.
	//	* If the UTF-8 flag is cleared, several readers simply interpret the

	//
	// In order to avoid breaking readers without UTF-8 support,
	// we avoid setting the UTF-8 flag if the strings are CP-437 compatible.

		} else {
			err = ObjectNotFound{
				Bucket: bucket,
				Object: object,
			}
		}
		return err
	}

	googleAPIErr, ok := err.(*googleapi.Error)
	if !ok {
		// We don't interpret non MinIO errors. As minio errors will
		// have StatusCode to help to convert to object errors.
		return err
	}

	if len(googleAPIErr.Errors) == 0 {
		return err
	}

some_variable: PlaneItem | CarItem
```

Mas se colocarmos isso na atribuição `response_model=PlaneItem | CarItem`, teríamos um erro, pois o Python tentaria executar uma **operação inválida** entre `PlaneItem` e `CarItem` em vez de interpretar isso como uma anotação de tipo.

## Lista de modelos { #list-of-models }

Da mesma forma, você pode declarar respostas de listas de objetos.

Para isso, use o padrão Python `list`:
