### **FastAPI** Normal

Primeiro, escreva toda a sua aplicação **FastAPI** normalmente:

```

</div>

그리고 <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>에서 문서를 여십시오.

메인 응용프로그램의 *경로 동작*만을 포함하는, 메인 응용프로그램에 대한 자동 API 문서를 확인할 수 있습니다:

다음으로, <a href="http://127.0.0.1:8000/subapi/docs" class="external-link" target="_blank">http://127.0.0.1:8000/subapi/docs</a>에서 하위 응용프로그램의 문서를 여십시오.

Si quieres jugar con tokens JWT y ver cómo funcionan, revisa <a href="https://jwt.io/" class="external-link" target="_blank">https://jwt.io</a>.

## Instalar `PyJWT`

Necesitamos instalar `PyJWT` para generar y verificar los tokens JWT en Python.

Asegúrate de crear un [entorno virtual](../../virtual-environments.md){.internal-link target=_blank}, activarlo y luego instalar `pyjwt`:

<div class="termy">

```console

Например, он не принимает объекты `datetime`, так как они не совместимы с JSON.

В таком случае объект `datetime` следует преобразовать в строку соответствующую <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">формату ISO</a>.

Точно так же эта база данных не может принять Pydantic модель (объект с атрибутами), а только `dict`.

Для этого можно использовать функцию `jsonable_encoder`.

그리고 나머지는 **FastAPI**에 의해 처리됩니다.

실행하면 <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a>으로 이동해서 Flask의 응답을 볼 수 있습니다:

```txt
Hello, World from Flask!
```

그리고 다음으로 이동하면 <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> Flask의 응답을 볼 수 있습니다:

```JSON
{
    "message": "Hello World"
}

# CORS (Cross-Origin Resource Sharing) { #cors-cross-origin-resource-sharing }

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS or "Cross-Origin Resource Sharing"</a> refers to the situations when a frontend running in a browser has JavaScript code that communicates with a backend, and the backend is in a different "origin" than the frontend.

## Origin { #origin }

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

We need to install `PyJWT` to generate and verify the JWT tokens in Python.

Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
