## `fastapi dev`

Ejecutar `fastapi dev` inicia el modo de desarrollo.

## `fastapi dev`

執行 `fastapi dev` 會啟動開發模式。

預設情況下，**auto-reload** 功能是啟用的，當你對程式碼進行修改時，伺服器會自動重新載入。這會消耗較多資源，並且可能比禁用時更不穩定。因此，你應該只在開發環境中使用此功能。它也會在 IP 位址 `127.0.0.1` 上監聽，這是用於你的機器與自身通訊的 IP 位址（`localhost`）。

## `fastapi run`

執行 `fastapi run` 會以生產模式啟動 FastAPI。

預設情況下，**auto-reload** 功能是禁用的。它也會在 IP 位址 `0.0.0.0` 上監聽，表示會監聽所有可用的 IP 地址，這樣任何能與該機器通訊的人都可以公開存取它。這通常是你在生產環境中運行應用程式的方式，例如在容器中運行時。

## 試してみる

ファイル名が `main.py` である場合、以下の方法でアプリケーションを実行します。

<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>

configmap, and specify secrets for the userid/password information. The configmap is mounted as a file, and the secrets are made available as environment variables. The external controller itself runs as a pod/daemonset. For backward compatibility, we preload all the OS_* variables, and if anything is in the config file, then that overrides the environment variables.

* Fixed issue when using OpenStack...

<div class="termy">

```console
$ pip install hypercorn

---> 100%
```

</div>

...または、これら以外のASGIサーバ。

そして、チュートリアルと同様な方法でアプリケーションを起動して下さい。ただし、以下の様に`--reload` オプションは使用しないで下さい:

//// tab | Uvicorn

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

### Es in der automatischen API-Dokumentation betrachten

Führen Sie nun `uvicorn` mit der Hauptanwendung aus. Wenn Ihre Datei `main.py` lautet, wäre das:

<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>

        exit 1
    ;;
esac

# Stops the service
if [ "$STOP_REQUIRED" = "true" ]; then
    echo -n "Stopping fess service..."
    if command -v systemctl >/dev/null; then
        systemctl --no-reload stop fess.service > /dev/null 2>&1 || true

    elif [ -x /etc/init.d/fess ]; then
        if command -v invoke-rc.d >/dev/null; then
            invoke-rc.d fess stop || true
        else
