### `Body` com `examples` { #body-with-examples }

Aqui passamos `examples` contendo um exemplo dos dados esperados em `Body()`:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

### `Body` con `examples` { #body-with-examples }

Aquí pasamos `examples` que contiene un ejemplo de los datos esperados en `Body()`:

```
https://www.external.org/events/invoices/2expen51ve
```

mit einem JSON-Body, der etwa Folgendes enthält:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

und sie würde eine Response von dieser *externen API* mit einem JSON-Body wie dem folgenden erwarten:

```JSON
{
    "ok": true
}
```
