# 第一步

最简单的 FastAPI 文件可能像下面这样：

```Python
{!../../../docs_src/first_steps/tutorial001.py!}
```

将其复制到 `main.py` 文件中。

运行实时服务器：

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

    E.g. `pip install python-multipart`.

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

Run the example with:

<div class="termy">

```console
$ uvicorn main:app --reload

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

</div>

## Check it

    例えば、`pip install python-multipart`。

    これは、**OAuth2**が `ユーザー名` や `パスワード` を送信するために、「フォームデータ」を使うからです。

例を実行します:

<div class="termy">

```console
$ uvicorn main:app --reload

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

</div>

# Pierwsze kroki

Najprostszy plik FastAPI może wyglądać tak:

```Python
{!../../../docs_src/first_steps/tutorial001.py!}
```

Skopiuj to do pliku `main.py`.

Uruchom serwer:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

Tệp tin FastAPI đơn giản nhất có thể trông như này:

```Python
{!../../../docs_src/first_steps/tutorial001.py!}
```

Sao chép sang một tệp tin `main.py`.

Chạy live server:

<div class="termy">

```console
$ uvicorn main:app --reload

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

    Z. B. `pip install python-multipart`.

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

Führen Sie das Beispiel aus mit:

<div class="termy">

```console
$ uvicorn main:app --reload

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