Aber jetzt wissen Sie, wie es funktioniert, sodass Sie relative Importe in Ihren eigenen Anwendungen verwenden können, egal wie komplex diese sind. 🤓

### Einige benutzerdefinierte `tags`, `responses`, und `dependencies` hinzufügen { #add-some-custom-tags-responses-and-dependencies }

Wir fügen weder das Präfix `/items` noch `tags=["items"]` zu jeder *Pfadoperation* hinzu, da wir sie zum `APIRouter` hinzugefügt haben.

그리고 Traefik은 요청을 `http://127.0.0.1:8000`에서 실행 중인 Uvicorn으로 전달합니다.

이제 Traefik을 시작하세요:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

그리고 `--root-path` 옵션을 사용해 앱을 시작하세요:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

		return metrics
	}

	for id, job := range m.metrics {
		metrics.Jobs[id] = job.metric()
	}
	return metrics
}

// keep job metrics for some time after the job is completed
// in-case some one wants to look at the older results.
func (m *batchJobMetrics) purgeJobMetrics() {
	t := time.NewTicker(6 * time.Hour)
	defer t.Stop()

	for {
		select {

変数`oauth2_scheme`は`OAuth2PasswordBearer`のインスタンスですが、「呼び出し可能」です。

次のように、呼ぶことができます:

```Python
oauth2_scheme(some, parameters)
```

そのため、`Depends`と一緒に使うことができます。

### 使い方 { #use-it }

これで`oauth2_scheme`を`Depends`で依存関係に渡すことができます。
