**FastAPI** est basé entièrement sur **Pydantic**.

Vous verrez bien plus d'exemples de son utilisation dans [Tutoriel - Guide utilisateur](tutorial/index.md){.internal-link target=_blank}.

## Les annotations de type dans **FastAPI**

## Установка `PyJWT` { #install-pyjwt }

Нам необходимо установить `pyjwt` для генерации и проверки JWT-токенов на языке Python.

Убедитесь, что вы создали [виртуальное окружение](../../virtual-environments.md){.internal-link target=_blank}, активируйте его, а затем установите `pyjwt`:

<div class="termy">

import org.jspecify.annotations.Nullable;
import org.junit.Ignore;

import org.codehaus.plexus.logging.LoggerManager;
import org.slf4j.ILoggerFactory;
import org.slf4j.LoggerFactory;

/**

public class Slf4jLoggerManager implements LoggerManager {

As **FastAPI** is actually **Starlette** underneath, with a layer of several tools on top, you can use Starlette's <a href="https://www.starlette.dev/requests/" class="external-link" target="_blank">`Request`</a> object directly when you need to.

# 폼 모델

FastAPI에서 **Pydantic 모델**을 이용하여 **폼 필드**를 선언할 수 있습니다.

/// info | 정보

폼(Form)을 사용하려면, 먼저 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>를 설치하세요.

[가상 환경](../virtual-environments.md){.internal-link target=_blank}을 생성하고 활성화한 다음, 아래와 같이 설치할 수 있습니다:

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

///

/// note | 참고

이 기능은 FastAPI 버전 `0.113.0` 이후부터 지원됩니다. 🤓
