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

Запустіть приклад:

<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>

ASGI 서버를 수동으로 설치했다면, 보통 FastAPI 애플리케이션을 임포트하기 위해 특별한 형식의 import string을 전달해야 합니다:

<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 | 참고

`uvicorn main:app` 명령은 다음을 가리킵니다:

* `main`: 파일 `main.py`(Python "module").

{* ../../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。

<div class="screenshot">

 * <li>the unreleased <b>maintenance</b>, M-1.d.e ( d &gt; 0, e &gt; 0) on the `(M-1).d` branch</li>
 * </ul>
 * In addition to these, there will be a fifth one when a minor reaches feature freeze, we call this the <i>staged</i>
 * version:
 * <ul>
 * <li>the unreleased <b>staged</b>, M.N-2.0 (N &gt; 2) on the `M.(N-2)` branch</li>
 * </ul>
 * <p>

### 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>
