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

But you can also declare multiple body parameters, e.g. `item` and `user`:

{* ../../docs_src/body_multiple_params/tutorial002_py310.py hl[20] *}


In this case, **FastAPI** will notice that there is more than one body parameter in the function (there are two parameters that are Pydantic models).

    /**
     * <code>user.dir</code> system property.
     */
    public static final String USER_DIR = System.getProperty("user.dir");

    /**
     * <code>user.home</code> system property.
     */
    public static final String USER_HOME = System.getProperty("user.home");

    /**
     * Returns the system property value for the specified key.
     *

     */
    @Required
    public String dictId;

    /**
     * The multipart file containing the Kuromoji user dictionary to be uploaded.
     * This file should be in the Kuromoji user dictionary format containing custom word definitions.

    @Required
    public MultipartFormFile kuromojiFile;

    /**
     * Default constructor for UploadForm.
     * Creates a new instance with default values.

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

{* ../../docs_src/body_multiple_params/tutorial002_py310.py hl[20] *}

En este caso, **FastAPI** notará que hay más de un parámetro del cuerpo en la función (hay dos parámetros que son modelos de Pydantic).
