```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

Nesse caso,  `fluffy` é uma instância da classe `Cat`.

E para criar `fluffy`, você está "chamando" `Cat`.

Então, uma classe Python também é "chamável".

Então, no **FastAPI**, você pode utilizar uma classe Python como uma dependência.

Bir hafta sonra token'ın süresi dolar; kullanıcı yetkilendirilmez ve yeni bir token almak için tekrar giriş yapmak zorunda kalır. Ayrıca kullanıcı (veya üçüncü bir taraf) token'ı değiştirip süre sonunu farklı göstermek isterse bunu tespit edebilirsiniz; çünkü imzalar eşleşmez.

As this is a WebSocket it doesn't really make sense to raise an `HTTPException`, instead we raise a `WebSocketException`.

You can use a closing code from the [valid codes defined in the specification](https://tools.ietf.org/html/rfc6455#section-7.4.1).

* `https://localhost`
* `http://localhost:8080`

Mesmo se todos estiverem em `localhost`, eles usam diferentes protocolos ou portas, portanto, são "origens" diferentes.

## Passos { #steps }

Die Reduzierung von Code-Verdoppelung ist eine der Kernideen von **FastAPI**.

Da die Verdopplung von Code die Wahrscheinlichkeit von Fehlern, Sicherheitsproblemen, Problemen mit der Desynchronisation des Codes (wenn Sie an einer Stelle, aber nicht an der anderen aktualisieren) usw. erhöht.

Und diese Modelle teilen alle eine Menge der Daten und verdoppeln Attributnamen und -typen.

Wir könnten es besser machen.
