### Bir *Yol Parametresi* Tanımlayalım

Sonrasında, yarattığımız enum sınıfını (`ModelName`) kullanarak tip belirteci aracılığıyla bir *yol parametresi* oluşturalım:

### Sadece modern Python

Tamamiyle standartlar **Python 3.8**'nın type hintlerine dayanıyor (Pydantic'in sayesinde). Yeni bir syntax öğrenmene gerek yok. Sadece modern Python.

Você pode ver esses schemas porque eles foram declarados com os modelos no app.

Essas informações estão disponíveis no **OpenAPI schema** do app e são mostradas na documentação da API (pelo Swagger UI).

E essas mesmas informações dos modelos que estão incluídas no OpenAPI são o que pode ser usado para **gerar o código do cliente**.

### Gerar um Cliente TypeScript

Agora que temos o app com os modelos, podemos gerar o código do cliente para o frontend.

    /**
     * Set a given project property. Properties set through this method are only valid
     * for the current build session and do not modify the underlying project model.

     * @param project the project to modify
     * @param key they property's key
     * @param value the value or {@code null} to unset the property

Создайте переменную `ALGORITHM` с алгоритмом, используемым для подписи JWT-токена, и установите для нее значение `"HS256"`.

Создайте переменную для срока действия токена.

Определите Pydantic Model, которая будет использоваться для формирования ответа на запрос на получение токена.

Создайте служебную функцию для генерации нового токена доступа.

inside and make sure it is serializable as JSON, using the same [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank} explained in the tutorial. This is what allows you to return **arbitrary objects**, for example database models.

But if you are certain that the content that you are returning is **serializable with JSON**, you can pass it directly to the response class and avoid the extra overhead that FastAPI would have by passing your return content through the...

Pydantic verhält sich speziell, wenn Sie `Optional` oder `Union[Etwas, None]` ohne einen Default-Wert verwenden.

## 토큰 반환하기

`token` 엔드포인트의 응답은 JSON 객체여야 합니다.

`token_type`이 있어야 합니다. 여기서는 "Bearer" 토큰을 사용하므로 토큰 유형은 "`bearer`"여야 합니다.
