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

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

<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)

Это связано с тем, что **OAuth2** использует «данные формы» для отправки `username` и `password`.

///

Запустите пример командой:

<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>

## Проверка { #check-it }

### 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。
