一個 Bash 程式碼範例...

```bash
# 向宇宙輸出問候
echo "Hello universe"
```

...以及一個主控台範例...

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>
<span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting server
        Searching for package file structure
```

...以及另一個主控台範例...

```console
// 建立目錄 "Code"

Entonces podrías desactivar OpenAPI (incluyendo las UI de documentación) configurando la variable de entorno `OPENAPI_URL` a una string vacía, así:

<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:

### Проверьте автоматическую документацию API { #check-the-automatic-api-docs }

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).

<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>

### Weiterleitungen mit HTTPS { #redirects-with-https }

Angenommen, Sie definieren eine *Pfadoperation* `/items/`:

### Revisa la documentación automática de la API { #check-the-automatic-api-docs }

Ahora, ejecuta el comando `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>

Y abre la documentación en [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

### Verifique a documentação automática da API { #check-the-automatic-api-docs }

Agora, execute o comando `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>

E abra a documentação em [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

	for arn := range sys.rolesMap {
		arns = append(arns, arn.String())
	}
	sort.Strings(arns)
	msgs := make([]string, 0, len(arns))
	for _, arn := range arns {
		msgs = append(msgs, color.Bold(arn))
	}

	logger.Info(fmt.Sprintf("%s %s", color.Blue("IAM Roles:"), strings.Join(msgs, " ")))
}

// HasWatcher - returns if the IAM system has a watcher to be notified of
// changes.
func (sys *IAMSys) HasWatcher() bool {

<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>

{* ../../docs_src/configure_swagger_ui/tutorial002_py310.py hl[3] *}

Esa configuración cambiaría el tema de color del resaltado de sintaxis:

## Cambiar los parámetros por defecto de Swagger UI { #change-default-swagger-ui-parameters }

<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>
