## 시도해보기 { #try-it }

코드를 `main.py` 파일에 넣고 애플리케이션을 실행합니다:

<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>

브라우저에서 [http://127.0.0.1:8000](http://127.0.0.1:8000)을 여세요.

간단한 페이지가 나타날 것입니다:

입력창에 메시지를 입력하고 전송할 수 있습니다:

     <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>
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Started parent process <b>[</b><font color="#34E2E2"><b>27365</b></font><b>]</b>

## 試試看 { #try-it }

如果你的檔案名為 `main.py`，用以下指令執行應用：

<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>

在瀏覽器開啟 [http://127.0.0.1:8000](http://127.0.0.1:8000)。

你會看到一個像這樣的簡單頁面：

你可以在輸入框輸入訊息並送出：

Cela peut également éviter toute confusion pour les nouveaux développeurs qui voient un paramètre inutilisé dans votre code et pourraient penser qu'il est superflu.

/// info | Info

Dans cet exemple, nous utilisons des en-têtes personnalisés fictifs `X-Key` et `X-Token`.

<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"
}

Теперь запустите команду `fastapi`:

<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>

И откройте документацию по адресу [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

	}

	stopProcess := func() bool {
		shutdownHealMRFWithTimeout() // this can take time sometimes, it needs to be executed
		// before stopping s3 operations

		// send signal to various go-routines that they need to quit.
		cancelGlobalContext()

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

Pydantic propose un [Guide de migration](https://docs.pydantic.dev/latest/migration/) officiel de la v1 à la v2.

Il inclut aussi ce qui a changé, comment les validations sont désormais plus correctes et strictes, les pièges possibles, etc.
