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

installieren.

Das liegt daran, dass **OAuth2** „Formulardaten“ zum Senden von `username` und `password` verwendet.

Führen Sie das Beispiel aus mit:

<div class="termy">

```console
$ fastapi dev

## 여러 워커 { #multiple-workers }

`--workers` 명령어 옵션으로 여러 워커를 시작할 수 있습니다:

//// tab | `fastapi`

`fastapi` 명령어를 사용한다면:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting production server 🚀

### Die automatische API-Dokumentation testen { #check-the-automatic-api-docs }

Führen Sie nun den Befehl `fastapi` aus:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Stellen Sie zunächst sicher, dass Sie Ihre [virtuelle Umgebung](../virtual-environments.md) erstellen, sie aktivieren und dann `sqlmodel` installieren:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

## Die App mit einem einzelnen Modell erstellen { #create-the-app-with-a-single-model }

## `PyJWT` 설치 { #install-pyjwt }

Python에서 JWT 토큰을 생성하고 검증하려면 `PyJWT`를 설치해야 합니다.

[가상환경](../../virtual-environments.md)을 만들고 활성화한 다음 `pyjwt`를 설치하십시오:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | 정보

RSA나 ECDSA 같은 전자 서명 알고리즘을 사용할 계획이라면, cryptography 라이브러리 의존성인 `pyjwt[crypto]`를 설치해야 합니다.

### Перевірте автоматичну документацію API { #check-the-automatic-api-docs }

Тепер запустіть команду `fastapi`:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

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

Це тому, що **OAuth2** використовує «form data» для надсилання `username` та `password`.

Запустіть приклад:

<div class="termy">

```console
$ fastapi dev

```

... und ein Konsolen-Codebeispiel ...

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>
<span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting server
        Searching for package file structure
```

... und noch ein Konsolen-Codebeispiel ...

```console
// Create a directory "Code"
$ mkdir code

Para usar formulários, primeiro instale [`python-multipart`](https://github.com/Kludex/python-multipart).

Certifique-se de criar um [ambiente virtual](../virtual-environments.md), ativá-lo e então instalá-lo, por exemplo:

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