# Primeros pasos

Un archivo muy simple de FastAPI podría verse así:

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

Copia eso a un archivo `main.py`.

Corre el servidor en vivo:

<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)

# Démarrage

Le fichier **FastAPI** le plus simple possible pourrait ressembler à cela  :

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

Copiez ce code dans un fichier nommé `main.py`.

Démarrez le serveur :

<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)

	Porque estamos usando uma URL relativa, se sua API estava localizada em `https://example.com/`, então irá referir-se à `https://example.com/token`. Mas se sua API estava localizada em `https://example.com/api/v1/`, então irá referir-se à `https://example.com/api/v1/token`.

    Поскольку мы используем относительный URL, если ваш API расположен по адресу `https://example.com/`, то он будет ссылаться на `https://example.com/token`. Если же ваш API расположен по адресу `https://example.com/api/v1/`, то он будет ссылаться на `https://example.com/api/v1/token`.

```

!!! tip "提示"

    在此，`tokenUrl="token"` 指向的是暂未创建的相对 URL `token`。这个相对 URL 相当于 `./token`。

    因为使用的是相对 URL，如果 API 位于 `https://example.com/`，则指向 `https://example.com/token`。但如果 API 位于 `https://example.com/api/v1/`，它指向的就是`https://example.com/api/v1/token`。

    使用相对 URL 非常重要，可以确保应用在遇到[使用代理](../../advanced/behind-a-proxy.md){.internal-link target=_blank}这样的高级用例时，也能正常运行。
