# 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.

# 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.

/// danger | Advertencia

Esta es una funcionalidad "avanzada".

    val ciGroup = "CI Lifecycle"

    register("quickTest") {
        description = "Run all unit, integration and cross-version (against latest release) tests in embedded execution mode"
        group = ciGroup
    }

    register("platformTest") {
        description = "Run all unit, integration and cross-version (against latest release) tests in forking execution mode"
        group = ciGroup
    }

# 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.

/// danger

This is an "advanced" feature.

```console
$ pip install python-multipart
```

///

## Importa `File` y `Form` { #import-file-and-form }

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[3] *}

## Define parámetros `File` y `Form` { #define-file-and-form-parameters }

Crea parámetros de archivo y formulario de la misma manera que lo harías para `Body` o `Query`:

```console
$ pip install python-multipart
```

///

## Importe `File` e `Form` { #import-file-and-form }

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[3] *}

## Defina parâmetros de `File` e `Form` { #define-file-and-form-parameters }

Crie parâmetros de arquivo e formulário da mesma forma que você faria para `Body` ou `Query`:

# Пользовательские классы Request и APIRoute { #custom-request-and-apiroute-class }

В некоторых случаях может понадобиться переопределить логику, используемую классами `Request` и `APIRoute`.

В частности, это может быть хорошей альтернативой логике в middleware.

Например, если вы хотите прочитать или изменить тело запроса до того, как оно будет обработано вашим приложением.

/// danger | Опасность

Это «продвинутая» возможность.
