# 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.

type parameter.

<p>
Each such pair of matched types corresponds to a <i>type equation</i> containing
one or multiple type parameters, from one or possibly multiple generic functions.
Inferring the missing type arguments means solving the resulting set of type
equations for the respective type parameters.

## Using the same dependency multiple times { #using-the-same-dependency-multiple-times }

If one of your dependencies is declared multiple times for the same *path operation*, for example, multiple dependencies have a common sub-dependency, **FastAPI** will know to call that sub-dependency only once per request.

        ("/required?foo=bar", 200, {"foo": "bar"}),
        ("/required", 422, foo_is_missing),
        ("/required?foo=", 422, foo_is_short),
        ("/multiple?foo=bar", 200, {"foo": "bar"}),
        ("/multiple", 422, foo_is_missing),
        ("/multiple?foo=", 422, foo_is_short),
        ("/unrelated?foo=bar", 200, {"foo": "bar"}),
        ("/unrelated", 422, foo_is_missing),
    ],
)

    ]
    response = client.post("/images/multiple", json=data)
    assert response.status_code == 200, response.text
    assert response.json() == data


def test_post_invalid_list_item(client: TestClient):
    data = [{"url": "not a valid url", "name": "Example"}]
    response = client.post("/images/multiple", json=data)
    assert response.status_code == 422, response.text

## Query parameter list / multiple values { #query-parameter-list-multiple-values }

When you define a query parameter explicitly with `Query` you can also declare it to receive a list of values, or said in another way, to receive multiple values.

For example, to declare a query parameter `q` that can appear multiple times in the URL, you can write:

        assertEquals("mybucket", getField(conn, "bucketName"));
        assertEquals("", getField(conn, "objectName"));
    }

    /**
     * Test URL with multiple consecutive slashes.
     * Note: Java's URL class does NOT normalize multiple slashes in the path.
     */
    public void test_urlParsing_multipleSlashes() throws Exception {
        URL url = new URL("gcs://mybucket//path//to//object.txt");
