## Execute o Programa Servidor { #run-the-server-program }

Se você instalou um servidor ASGI manualmente, normalmente precisará passar uma string de importação em um formato especial para que ele importe sua aplicação FastAPI:

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

Mas se você quiser que ele espere por um JSON com uma chave `item` e dentro dele os conteúdos do modelo, como ocorre ao declarar vários parâmetros de corpo, você pode usar o parâmetro especial de `Body` chamado `embed`:

```Python
item: Item = Body(embed=True)
```

como em:

{* ../../docs_src/body_multiple_params/tutorial005_an_py310.py hl[17] *}

/// tip | Consejo

Prefiere usar la versión `Annotated` si es posible.

///

```Python
commons: CommonQueryParams ...
```

////

...no tiene ningún significado especial para **FastAPI**. **FastAPI** no lo usará para la conversión de datos, validación, etc. (ya que está usando `Depends(CommonQueryParams)` para eso).

De hecho, podrías escribir simplemente:

//// tab | Python 3.9+

* declarar el parámetro de query `q` sin un `Query` ni ningún valor por defecto
* declarar el parámetro de path `item_id` usando `Path`
* tenerlos en un orden diferente
* no usar `Annotated`

...Python tiene una sintaxis especial para eso.

Pasa `*`, como el primer parámetro de la función.

# Extra Models { #extra-models }

Continuing with the previous example, it will be common to have more than one related model.

This is especially the case for user models, because:

* The **input model** needs to be able to have a password.
* The **output model** should not have a password.
* The **database model** would probably need to have a hashed password.
