Put your code in a file `main.py` and then run your application:

<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>

Open your browser at [http://127.0.0.1:8000](http://127.0.0.1:8000).

You will see a simple page like:

<img src="/img/tutorial/websockets/image01.png">

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Uvicorn running on <font color="#729FCF"><u style="text-decoration-style:solid">http://0.0.0.0:8000</u></font> <b>(</b>Press CTRL+C
             to quit<b>)</b>
```

</div>

В большинстве случаев этого достаточно. 😎

Этой командой, например, можно запускать приложение **FastAPI** в контейнере, на сервере и т.д.

## ASGI‑серверы { #asgi-servers }

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Uvicorn running on <font color="#729FCF"><u style="text-decoration-style:solid">http://0.0.0.0:8000</u></font> <b>(</b>Press CTRL+C
             to quit<b>)</b>
```

</div>

Isto deve funcionar para a maioria dos casos. 😎

Você pode utilizar esse comando, por exemplo, para iniciar sua aplicação **FastAPI** em um contêiner, em um servidor, etc.

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Uvicorn running on <font color="#729FCF"><u style="text-decoration-style:solid">http://0.0.0.0:8000</u></font> <b>(</b>Press CTRL+C
             to quit<b>)</b>
```

</div>

Cela fonctionnerait pour la plupart des cas. 😎

Vous pourriez utiliser cette commande par exemple pour démarrer votre application **FastAPI** dans un conteneur, sur un serveur, etc.

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Uvicorn running on <font color="#729FCF"><u style="text-decoration-style:solid">http://0.0.0.0:8000</u></font> <b>(</b>Press CTRL+C
             to quit<b>)</b>
```

</div>

Це спрацює в більшості випадків. 😎

Цю команду можна використати, наприклад, щоб запустити ваш застосунок FastAPI у контейнері, на сервері тощо.

## Сервери ASGI { #asgi-servers }

	// Forward SIGQUIT from the go command to show backtraces from
	// the binary instead of from this wrapper.
	quit := make(chan os.Signal, 1)
	signal.Notify(quit, syscall.SIGQUIT)
	go func() {
		for range quit {
			// We don't have the PID of the running process; use the
			// binary name instead.
			adb("exec-out", "killall -QUIT "+binName)
		}
	}()
	cmd := `export TMPDIR="` + deviceGotmp + `"` +

## 尝试一下 { #try-it }

将代码放在 `main.py`，然后运行你的应用程序：

<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>

在浏览器中打开 [http://127.0.0.1:8000](http://127.0.0.1:8000)。

您将看到一个简单的页面，如下所示：

<img src="/img/tutorial/websockets/image01.png">

您可以在输入框中输入消息并发送：

<div class="termy">

```console
$ fastapi run --forwarded-allow-ips="*"

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

</div>

### HTTPS에서 리디렉션 { #redirects-with-https }

예를 들어, *경로 처리* `/items/`를 정의했다고 해봅시다:

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.py hl[6] *}

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Uvicorn running on <font color="#729FCF"><u style="text-decoration-style:solid">http://0.0.0.0:8000</u></font> <b>(</b>Press CTRL+C
             to quit<b>)</b>
```

</div>

Das würde in den meisten Fällen funktionieren. 😎

Sie könnten diesen Befehl beispielsweise verwenden, um Ihre **FastAPI**-App in einem Container, auf einem Server usw. zu starten.

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Uvicorn running on <font color="#729FCF"><u style="text-decoration-style:solid">http://0.0.0.0:8000</u></font> <b>(</b>Press CTRL+C
             to quit<b>)</b>
```

</div>

That would work for most of the cases. 😎

You could use that command for example to start your **FastAPI** app in a container, in a server, etc.
