## Validação adicional { #additional-validation }

Vamos impor que, embora `q` seja opcional, sempre que for fornecido, **seu comprimento não exceda 50 caracteres**.

### Importe `Query` e `Annotated` { #import-query-and-annotated }

Para isso, primeiro importe:

* `Query` de `fastapi`
* `Annotated` de `typing`

constraints.EAN.message = {item} não é um código de barras {type} válido.
constraints.Email.message = {item} não é um endereço de e-mail válido.
constraints.Length.message = O comprimento de {item} deve estar entre {min} e {max}.
constraints.LuhnCheck.message = A soma de verificação Luhn Módulo 11 de {value} está incorreta.
constraints.Mod10Check.message = A soma de verificação Módulo 10 de {value} está incorreta.

    above. See [Jetty's overview][jetty_8_252] of the API change and its consequences.

 *  New: `MultipartReader` is a streaming decoder for [MIME multipart (RFC 2045)][rfc_2045]
    messages. It complements `MultipartBody` which is our streaming encoder.

    ```kotlin
    val response: Response = call.execute()
    val multipartReader = MultipartReader(response.body!!)

    multipartReader.use {
