## Handhaben von benutzerdefinierten Requestbody-Kodierungen { #handling-custom-request-body-encodings }

Sehen wir uns an, wie Sie eine benutzerdefinierte `Request`-Unterklasse verwenden, um gzip-Requests zu dekomprimieren.

Und eine `APIRoute`-Unterklasse zur Verwendung dieser benutzerdefinierten Requestklasse.

Sehen wir uns das alles anhand eines Beispiels an.

Stellen Sie sich vor, Sie entwickeln eine Anwendung, mit der Sie Rechnungen erstellen können.

Diese Rechnungen haben eine `id`, einen optionalen `title`, einen `customer` (Kunde) und ein `total` (Gesamtsumme).
