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

 *
 * @since 4.0.0
 */
@Experimental
public interface MessageBuilderFactory extends Service {
    /**
     * Checks if the underlying output does support styling or not.
     * @return whether color styling is supported or not
     */
    boolean isColorEnabled();

    /**
     * Returns the terminal width or <code>-1</code> if not supported.
     * @return the terminal width
     */

```bash
# Print a greeting to the universe
echo "Hello universe"
```

...and a console code example...

```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
```

...and another console code example...

```console

本例中的 `Proxy` 是 **Traefik**，`server` 是运行 FastAPI 应用的 **Uvicorn**。

### 提供 `root_path`

为此，要以如下方式使用命令行选项 `--root-path`：

<div class="termy">

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

Hypercorn 也支持 `--root-path `选项。

/// note | 技术细节

ASGI 规范定义的 `root_path` 就是为了这种用例。

        request = new CliRequest(new String[] {"-Dstyle.color=always"}, null);
        cli.cli(request);
        cli.properties(request);
        cli.logging(request);
        assertTrue(MessageUtils.isColorEnabled(), "Expected MessageUtils.isColorEnabled() to return true");

        MessageUtils.setColorEnabled(true);
        request = new CliRequest(new String[] {"-Dstyle.color=never"}, null);
        cli.cli(request);

func (er *erasureObjects) saveMetaCacheStream(ctx context.Context, mc *metaCacheRPC, entries <-chan metaCacheEntry) (err error) {
	o := mc.o
	o.debugf(color.Green("saveMetaCacheStream:")+" with options: %#v", o)

	metaMu := &mc.mu
	rpc := mc.rpc
	cancel := mc.cancel
	defer func() {
		o.debugln(color.Green("saveMetaCacheStream:")+"err:", err)
		if err != nil && !errors.Is(err, io.EOF) {
			go mc.setErr(err.Error())
			cancel()
		}

		return fmt.Sprintf("msg: %s\n err:%s", introMsg, err)
	}
)

// EnableQuiet - turns quiet option on.
func EnableQuiet() {
	color.TurnOff() // no colored outputs necessary in quiet mode.
	quietFlag = true
}

// EnableJSON - outputs logs in json format.
func EnableJSON() {
	color.TurnOff() // no colored outputs necessary in JSON mode.
	jsonFlag = true
	quietFlag = true
}

// EnableAnonymous - turns anonymous flag

```bash
# Imprime un saludo al universo
echo "Hello universe"
```

...y un ejemplo de código de consola...

```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
```

...y otro ejemplo de código de consola...

```console

<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>

### Redirecciones con HTTPS { #redirects-with-https }

Далее вы можете отключить OpenAPI (включая интерфейсы документации), установив переменную окружения `OPENAPI_URL` в пустую строку, например:

<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>

После этого, если перейти по адресам `/openapi.json`, `/docs` или `/redoc`, вы получите ошибку `404 Not Found`, например:
