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

They will receive an **error** response telling them that the query parameter `tool` is not allowed:

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

Elle ne sera pas sérialisée avec un modèle, etc.

Vous devez vous assurer qu'elle contient les données souhaitées et que les valeurs sont dans un format JSON valide (si vous utilisez une `JSONResponse`).

///

/// note | Détails techniques

Vous pouvez également utiliser `from starlette.responses import JSONResponse`.

Lembre-se de que se você retornar uma resposta diretamente em vez de usar o parâmetro `Response`, FastAPI a retornará diretamente.

Portanto, você terá que garantir que seus dados sejam do tipo correto. E.g. será compatível com JSON se você estiver retornando um `JSONResponse`.

E também que você não esteja enviando nenhum dado que deveria ter sido filtrado por um `response_model`.

Наприклад, якщо клієнт спробує надіслати заголовок `tool` зі значенням `plumbus`, він отримає **помилку** у відповіді з повідомленням про те, що параметр заголовка `tool` не дозволений:

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

	while [ "$u" != "0" ]; do
		sudo umount ${WORK_DIR}/mnt/disk4/
		u=$?
		sleep 1
	done

	# Wait until MinIO self heal kicks in
	sleep 60

	if [ -f ${WORK_DIR}/mnt/disk4/.minio.sys/format.json ]; then
		echo "A root disk is formatted unexpectedely"
		cat "${WORK_DIR}/server4.log"
		exit -1
	fi
}

function cleanup() {
	pkill minio
	sudo umount ${WORK_DIR}/mnt/disk{1..3}/

А если вы перейдёте по [http://localhost:8000/v2](http://localhost:8000/v2), вы увидите HTTP‑ответ от FastAPI:

```JSON
{
    "message": "Hello World"
}

func (err *s3Error) Error() string {
	return err.message
}

func errJSONParsingError(err error) *s3Error {
	return &s3Error{
		code:       "JSONParsingError",
		message:    fmt.Sprintf("Encountered an error parsing the JSON file: %v. Check the file and try again.", err),
		statusCode: 400,
		cause:      err,
	}

For internal purposes, we use binary formats for their brevity.
We use the `Serializer` abstraction to separate the actual implementation of serialization from its uses.

When sharing data with external tools, we use JSON.

## Consequences

* The configuration cache serialization infrastructure should be used for all serialization.
* Existing usages of Serializer outside of this infrastructure should be migrated to use it.
