То в ответ он получит **ошибку**, сообщающую ему, что поле `extra` не разрешено:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],
            "msg": "Extra inputs are not permitted",
            "input": "Mr. Poopybutthole"
        }
    ]
}
```

Por ejemplo, si el cliente intenta enviar un header `tool` con un valor de `plumbus`, recibirán un response de **error** indicando que el parámetro de header `tool` no está permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

You can define this *startup* and *shutdown* logic using the `lifespan` parameter of the `FastAPI` app, and a "context manager" (I'll show you what that is in a second).

Let's start with an example and then see it in detail.

We create an async function `lifespan()` with `yield` like this:

{* ../../docs_src/events/tutorial003.py hl[16,19] *}

```http
https://example.com/items/?limit=10&tool=plumbus
```

Recibirán un response de **error** que les indica que el parámetro query `tool` no está permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus"
        }
    ]
}
```

```http
https://example.com/items/?limit=10&tool=plumbus
```

Він отримає відповідь з **помилкою**, яка повідомить, що query параметр `tool ` не дозволено:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus"
        }
    ]
}
```

```

```JSON

}

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

They will receive an error response telling them that the field `extra` is not allowed:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["body", "extra"],

        }
    ]
}
```

```http
https://example.com/items/?limit=10&tool=plumbus
```

Eles receberão um retorno de **erro** informando-os que o parâmentro de consulta `tool` não é permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],
