Call the endpoint `/users/me/`, you will get the response as:

```JSON

Si un cliente intenta enviar datos extra, recibirá un response de **error**.

Por ejemplo, si el cliente intenta enviar los campos de formulario:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

Recibirá un response de error indicando que el campo `extra` no está permitido:

```json
{
    "detail": [
        {

```JSON
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    },
    "user": {
        "username": "dave",
        "full_name": "Dave Grohl"
    }
}
```

/// note | 참고

이전과 같이 `item`이 선언 되었더라도, 본문 내의 `item` 키가 있을 것이라고 예측합니다.
