## Pour résumer

Avec `Query`, `Path` (et d'autres que vous verrez plus tard) vous pouvez déclarer des métadonnées et des validations de chaînes de la même manière qu'avec les [Paramètres de requête et validations de chaînes](query-params-str-validations.md){.internal-link target=_blank}.

Et vous pouvez également déclarer des validations numériques :

                        .status(ApiResult.Status.OK)
                        .result());
    }

    /**
     * Retrieves a specific related query setting by ID.
     *
     * @param id the ID of the related query to retrieve
     * @return JSON response containing the related query configuration
     */
    // GET /api/admin/relatedquery/setting/{id}
    @Execute
    public JsonResponse<ApiResult> get$setting(final String id) {

`Header` is a "sister" class of `Path`, `Query` and `Cookie`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Header`, and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare headers, you need to use `Header`, because otherwise the parameters would be interpreted as query parameters.

///

     * The search is performed using the current virtual host context and
     * the query term is converted to lowercase for case-insensitive matching.
     *
     * @param query the search term to find related queries for
     * @return an array of related query strings, or empty array if none found
     */
    public String[] getRelatedQueries(final String query) {
        final String key = ComponentUtil.getVirtualHostHelper().getVirtualHostKey();

/**
 * Response object for faceted search results containing query counts and field facets.
 * This class processes OpenSearch aggregations to provide structured facet information
 * for search result filtering and navigation.
 */
public class FacetResponse {
    /**
     * Map containing query facet counts, where keys are decoded query strings
     * and values are document counts for each query.
     */

///

## Declarar atributos del modelo

Después puedes utilizar `Field` con los atributos del modelo:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

`Field` funciona de la misma manera que `Query`, `Path` y `Body`, tiene todos los mismos parámetros, etc.

/// note | Detalles técnicos

        assertEquals("_default:fess", ((TermQuery) query).getTerm().toString());

        query = queryParser.createDefaultFilterChain().parse("title:fess");
        assertEquals(TermQuery.class, query.getClass());
        assertEquals("title:fess", ((TermQuery) query).getTerm().toString());

        query = queryParser.createDefaultFilterChain().parse("fess*");
        assertEquals(PrefixQuery.class, query.getClass());

# Тіло запиту - Декілька параметрів

Тепер, коли ми розглянули використання `Path` та `Query`, розгляньмо більш просунуті способи оголошення тіла запиту в **FastAPI**.

## Змішування `Path`, `Query` та параметрів тіла запиту

По-перше, звісно, Ви можете вільно змішувати оголошення параметрів `Path`, `Query` та тіла запиту, і **FastAPI** правильно їх обробить.

 * list is a single empty string: `[""]`.
 *
 * ### Query
 *
 * The query is optional: it can be null, empty, or non-empty. For many HTTP URLs the query string
 * is subdivided into a collection of name-value parameters. This class offers methods to set the
 * query as the single string, or as individual name-value parameters. With name-value parameters
