```Python
{"id": id}
```

Por exemplo, dado um ID de valor `42`, aparecerá:

```html
Item ID: 42
```

### Argumentos do `url_for`

Você também pode usar `url_for()` dentro do template, ele recebe como argumentos os mesmos argumentos que seriam usados pela sua *path operation function*.

Logo, a seção com:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

* **`200`** e acima são para respostas "Bem-sucedidas". Estes são os que você mais usaria.
    * `200` é o código de status padrão, o que significa que tudo estava "OK".
    * Outro exemplo seria `201`, "Criado". É comumente usado após a criação de um novo registro no banco de dados.
    * Um caso especial é `204`, "Sem Conteúdo". Essa resposta é usada quando não há conteúdo para retornar ao cliente e, portanto, a resposta não deve ter um corpo.

Para esos casos, puedes usar el `jsonable_encoder` para convertir tus datos antes de pasarlos a la respuesta:

```Python hl_lines="4 6 20 21"
{!../../../docs_src/response_directly/tutorial001.py!}
```

!!! note "Detalles Técnicos"
    También puedes usar `from starlette.responses import JSONResponse`.
