```

This is because **OAuth2** uses "form data" for sending the `username` and `password`.

///

Run the example with:

<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>

## Check it { #check-it }

Go to the interactive docs at: [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

Cela est dû au fait que **OAuth2** utilise des « form data » pour envoyer le `username` et le `password`.

///

Exécutez l'exemple avec :

<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>

## Vérifier { #check-it }

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[66:73] hl[71] *}

### 執行應用 { #run-the-app }

你可以執行應用：

<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>

然後前往 `/docs` 的 UI，你會看到 FastAPI 使用這些模型來「文件化」API，也會用它們來「序列化」與「驗證」資料。

Führen Sie das Beispiel aus mit:

<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>

## Es testen { #check-it }

Sonra o varlık için izinler ekleyebilirsiniz; örneğin (araba için) "drive" ya da (blog için) "edit".

Ardından bu JWT token'ını bir kullanıcıya (veya bot'a) verebilirsiniz; onlar da, hesapları olmasına bile gerek kalmadan, sadece API'nizin bunun için ürettiği JWT token'ıyla bu aksiyonları gerçekleştirebilir (arabayı sürmek veya blog post'u düzenlemek gibi).

Bu fikirlerle JWT, çok daha gelişmiş senaryolarda kullanılabilir.

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

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

### 运行应用 { #run-the-app }

你可以运行这个应用：

<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>

然后在 `/docs` UI 中，你能够看到 **FastAPI** 会用这些**模型**来**记录** API，并且还会用它们来**序列化**和**验证**数据。

<div class="screenshot">

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

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

</div>

/// tip | Tipp

ASGI サーバーを手動でインストールした場合、通常は FastAPI アプリケーションをインポートさせるために、特別な形式のインポート文字列を渡す必要があります:

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

<span style="color: green;">INFO</span>:     Uvicorn running on http://0.0.0.0:80 (Press CTRL+C to quit)
```

</div>

/// note | 備考

`uvicorn main:app` というコマンドは次を指します:

* `main`: ファイル `main.py`（Python の「モジュール」）。
