<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>

Öffnen Sie Ihren Browser unter <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>.

Sie sehen eine einfache Seite wie:

If your file is named `main.py`, run your application with:

<div class="termy">

```console
$ fastapi dev main.py

<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 <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>.

You will see a simple page like:

```

</div>

以下のようなアプリを作成したとき:

{* ../../docs_src/first_steps/tutorial002.py hl[3] *}

そして、それを`main.py`ファイルに置き、次のように`uvicorn`を呼び出します:

<div class="termy">

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

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

</div>

<div class="termy">

```console
$ fastapi run main.py --root-path /api/v1

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

</div>

Si usas Hypercorn, también tiene la opción `--root-path`.

La especificación ASGI define un `root_path` para este caso de uso.

## 시도해보기

파일 이름이 `main.py`라고 가정하고 응용 프로그램을 실행합니다:

<div class="termy">

```console
$ fastapi dev main.py

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

</div>

브라우저에서 <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>을 열어보세요.

간단한 페이지가 나타날 것입니다:

	go func() {
		saveTicker := time.NewTicker(10 * time.Second)
		defer saveTicker.Stop()
		quit := false
		after := time.Minute
		for !quit {
			select {
			case <-saveTicker.C:
			case <-ctx.Done():
				quit = true
			case <-saverQuitCh:
				quit = true
			}

			if quit {
				// save immediately if we are quitting
				after = 0
			}

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Wenn Sie dann zu den URLs unter `/openapi.json`, `/docs` oder `/redoc` gehen, erhalten Sie lediglich einen `404 Not Found`-Fehler, wie:

```JSON
{
    "detail": "Not Found"
}

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Luego, si vas a las URLs en `/openapi.json`, `/docs`, o `/redoc`, solo obtendrás un error `404 Not Found` como:

```JSON
{
    "detail": "Not Found"
}

<div class="termy">

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

		cancelGlobalContext()

		if httpServer := newHTTPServerFn(); httpServer != nil {
			if err := httpServer.Shutdown(); err != nil && !errors.Is(err, http.ErrServerClosed) {
