# Request e classe APIRoute personalizadas { #custom-request-and-apiroute-class }

Em alguns casos, você pode querer sobrescrever a lógica usada pelas classes `Request` e `APIRoute`.

Em particular, isso pode ser uma boa alternativa para uma lógica em um middleware.

Por exemplo, se você quiser ler ou manipular o corpo da requisição antes que ele seja processado pela sua aplicação.

/// danger | Cuidado

Isso é um recurso "avançado".

# Benutzerdefinierte Request- und APIRoute-Klasse { #custom-request-and-apiroute-class }

In einigen Fällen möchten Sie möglicherweise die von den Klassen `Request` und `APIRoute` verwendete Logik überschreiben.

Das kann insbesondere eine gute Alternative zur Logik in einer Middleware sein.

Wenn Sie beispielsweise den <abbr title="Anfragekörper">Requestbody</abbr> lesen oder manipulieren möchten, bevor er von Ihrer Anwendung verarbeitet wird.

## Определите параметры `File` и `Form` { #define-file-and-form-parameters }

Создайте параметры файла и формы таким же образом, как для `Body` или `Query`:

# Clase personalizada de Request y APIRoute { #custom-request-and-apiroute-class }

En algunos casos, puede que quieras sobrescribir la lógica utilizada por las clases `Request` y `APIRoute`.

En particular, esta puede ser una buena alternativa a la lógica en un middleware.

Por ejemplo, si quieres leer o manipular el request body antes de que sea procesado por tu aplicación.

    val ciGroup = "CI Lifecycle"

    register("quickTest") {

# Custom Request and APIRoute class { #custom-request-and-apiroute-class }

In some cases, you may want to override the logic used by the `Request` and `APIRoute` classes.

In particular, this may be a good alternative to logic in a middleware.

For example, if you want to read or manipulate the request body before it is processed by your application.

# Request Forms and Files { #request-forms-and-files }

You can define files and form fields at the same time using `File` and `Form`.
