You just pass it to `Depends` and **FastAPI** knows how to do the rest.

## Share `Annotated` dependencies

In the examples above, you see that there's a tiny bit of **code duplication**.

When you need to use the `common_parameters()` dependency, you have to write the whole parameter with the type annotation and `Depends()`:

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

      Request.Builder()
        .url(server.url("/"))
        .build()

    // No extra headers in the application's request.
    assertThat(request.header("User-Agent")).isNull()
    assertThat(request.header("Host")).isNull()
    assertThat(request.header("Accept-Encoding")).isNull()

    // No extra headers in the application's response.
    val response = client.newCall(request).execute()

	}

	return res, nil
}

// Enabled returns if configURL is enabled.
func Enabled(kvs config.KVS) bool {
	return kvs.Get(ConfigURL) != ""
}

// GetSettings - fetches OIDC settings for site-replication related validation.
// NOTE that region must be populated by caller as this package does not know.
func (r *Config) GetSettings() madmin.OpenIDSettings {
	res := madmin.OpenIDSettings{}
	if !r.Enabled {
		return res

            task.into(extension.getUserManual().getStagingRoot().dir("final"));
            // TODO: Eliminate this duplication with the flatten task
            task.from(extension.getUserManual().getRoot().dir("img"), sub -> {

Cualquier integración está diseñada para que sea tan sencilla de usar (con dependencias) que puedas crear un "plug-in" para tu aplicación en dos líneas de código usando la misma estructura y sintaxis que usaste para tus *path operations*.

Dann wird er nicht in das OpenAPI-Schema aufgenommen.

## Mounten einer Unteranwendung

Wenn Sie gleichzeitig eine Unteranwendung mounten (wie beschrieben in [Unteranwendungen – Mounts](sub-applications.md){.internal-link target=_blank}) und einen Proxy mit `root_path` verwenden wollen, können Sie das normal tun, wie Sie es erwarten würden.

```Python hl_lines="9"
{!../../docs_src/behind_a_proxy/tutorial004.py!}
```

这样，就不会在 OpenAPI 概图中包含服务器了。

## 挂载子应用

如需挂载子应用（详见 [子应用 - 挂载](sub-applications.md){.internal-link target=_blank}），也要通过 `root_path` 使用代理，这与正常应用一样，别无二致。
