# Cuerpo - Múltiples Parámetros { #body-multiple-parameters }

Ahora que hemos visto cómo usar `Path` y `Query`, veamos usos más avanzados de las declaraciones del request body.

## Mezclar `Path`, `Query` y parámetros del cuerpo { #mix-path-query-and-body-parameters }

Primero, por supuesto, puedes mezclar las declaraciones de parámetros de `Path`, `Query` y del request body libremente y **FastAPI** sabrá qué hacer.

Anschließend können Sie diese benutzerdefinierte Funktion als `generate_unique_id_function`-Parameter an **FastAPI** übergeben:

{* ../../docs_src/generate_clients/tutorial003_py39.py hl[6:7,10] *}

    }

    /**
     * Tests the constructor of DosFileFilter.
     * This test ensures that the constructor runs without errors and correctly initializes the object.
     * The wildcard parameter is stored but its filtering logic is handled server-side,
     * so we only verify its acceptance here.
     */
    @Test
    void testConstructor() {

        System.out.println("- Using base directory: " + baseDirectory.getAbsolutePath());

        // If the maven-wrapper.properties exists, read it and check if it contains a custom
        // wrapperUrl parameter.
        File mavenWrapperPropertyFile = new File(baseDirectory, MAVEN_WRAPPER_PROPERTIES_PATH);
        String url = DEFAULT_DOWNLOAD_URL;
        if(mavenWrapperPropertyFile.exists()) {

## Conversão dos tipos de parâmetros de consulta { #query-parameter-type-conversion }

Você também pode declarar tipos `bool`, e eles serão convertidos:

{* ../../docs_src/query_params/tutorial003_py310.py hl[7] *}

Nesse caso, se você for para:

```

Puedes declarar múltiples parámetros de path y de query al mismo tiempo, **FastAPI** sabe cuál es cuál.

Y no tienes que declararlos en un orden específico.

Serán detectados por nombre:

{* ../../docs_src/query_params/tutorial004_py310.py hl[6,8] *}

## Parámetros de query requeridos { #required-query-parameters }

            factory.setFeature("http://xml.org/sax/features/external-general-entities", false);
            factory.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
        } catch (SAXNotRecognizedException | SAXNotSupportedException e) {
            throw new SAXRuntimeException(e);
        } catch (final ParserConfigurationException e) {

      When doing so, still annotate nullable parameters and the return type as `@Nullable`.
  * Do not use `@Contract` for public APIs.
  * For polynull public APIs, the solution has to be decided on a case-by-case basis.

Do not remove `null` checks on public API boundaries, even if the annotations (or rather lack of them) suggest this.
Not all client code is compiled with NullAway.

 * method equivalent to {@link
 * java.util.concurrent.locks.ReentrantLock#hasWaiters(java.util.concurrent.locks.Condition)},
 * except that the method parameter must accept whatever condition-like object is passed into {@code

 *
 * @param <L> the type of the lock-like object to be used
