## Additional validation { #additional-validation }

We are going to enforce that even though `q` is optional, whenever it is provided, **its length doesn't exceed 50 characters**.

### Import `Query` and `Annotated` { #import-query-and-annotated }

To achieve that, first import:

* `Query` from `fastapi`
* `Annotated` from `typing`

type objectHistogramInterval struct {
	name       string
	start, end int64
}

const (
	// dataUsageBucketLenV1 must be length of ObjectsHistogramIntervalsV1
	dataUsageBucketLenV1 = 7
	// dataUsageBucketLen must be length of ObjectsHistogramIntervals
	dataUsageBucketLen  = 11
	dataUsageVersionLen = 7
)

// ObjectsHistogramIntervalsV1 is the list of all intervals

        }
    }

    private static void validateMappingString(final FessBaseAction action, final String[] values, final String propertyName,
            final VaErrorHook hook) {
        if (values.length == 0) {
            return;
        }
        for (final String value : values) {

* `status_code` - An `int` HTTP status code.
* `headers` - A `dict` of strings.
* `media_type` - A `str` giving the media type. E.g. `"text/html"`.

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the `media_type` and appending a charset for text types.

### `HTMLResponse` { #htmlresponse }

* `status_code` – Ein `int`-HTTP-Statuscode.
* `headers` – Ein `dict` von Strings.
* `media_type` – Ein `str`, der den Medientyp angibt. Z. B. `"text/html"`.

FastAPI (eigentlich Starlette) fügt automatisch einen Content-Length-Header ein. Außerdem wird es einen Content-Type-Header einfügen, der auf dem media_type basiert, und für Texttypen einen Zeichensatz (charset) anfügen.
