### 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」）。

<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 | İpucu

```

Esto se debe a que **OAuth2** utiliza "form data" para enviar el `username` y `password`.

///

Ejecuta el ejemplo con:

<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>

## Revisa { #check-it }

Ve a la documentación interactiva en: [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

```

Isso ocorre porque o **OAuth2** usa "form data" para enviar o `username` e o `password`.

///

Execute o exemplo com:

<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>

## Verifique-o { #check-it }

Bir response modeliyle FastAPI, veriyi JSON’a serialize etmek için Pydantic’i kullanır; böylece diğer durumlarda olacağı gibi `jsonable_encoder` ile ara dönüşümlere gerek kalmaz.

Ve kaputun altında, Pydantic JSON’a serialize etmek için `orjson` ile aynı Rust tabanlı mekanizmaları kullanır; bu nedenle bir response modeliyle zaten en iyi performansı elde edersiniz.

<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)
```
