Pero primero, vamos a revisar algunos pequeños conceptos.

## ¿Con prisa? { #in-a-hurry }

Si no te importan ninguno de estos términos y solo necesitas agregar seguridad con autenticación basada en nombre de usuario y contraseña *ahora mismo*, salta a los siguientes capítulos.

## OAuth2 { #oauth2 }

    Como siempre, en FastAPI puedes combinar `def` y `async def` según sea necesario.

    Si necesitas un repaso sobre cuándo usar cuál, revisa la sección _"¿Con prisa?"_ en la documentación sobre [`async` y `await`](../async.md#in-a-hurry).

9. Esta *path operation function* no está devolviendo dataclasses (aunque podría), sino una lista de diccionarios con datos internos.

    Se você precisar de uma atualização sobre quando usar qual, confira a seção _"Com pressa?"_ na documentação sobre [`async` e `await`](../async.md#in-a-hurry).

9. Esta *função de operação de rota* não está retornando dataclasses (embora pudesse), mas uma lista de dicionários com dados internos.

* proprietary: проприетарный
* benchmark: бенчмарк (add (`тест производительности`) if clarification is needed or use just `тест производительности`)
* ASGI server: ASGI-сервер
* In a hurry? : Нет времени?
* response status code: статус-код ответа
* HTTP status code: HTTP статус-код
* issue (meaning GitHub issue): Issue (add `тикет\обращение` if clarification is needed)

func (e stsErrorCodeMap) ToSTSErr(errCode STSErrorCode) STSError {
	apiErr, ok := e[errCode]
	if !ok {
		return e[ErrSTSInternalError]
	}
	return apiErr
}

// error code to STSError structure, these fields carry respective
// descriptions for all the error responses.
var stsErrCodes = stsErrorCodeMap{
	ErrSTSAccessDenied: {
		Code:           "AccessDenied",

func (r *ReplicationStats) ActiveWorkers() ActiveWorkerStat {
	if r == nil {
		return ActiveWorkerStat{}
	}
	r.wlock.RLock()
	defer r.wlock.RUnlock()
	w := r.workers.get()
	return ActiveWorkerStat{
		Curr: w.Curr,
		Max:  w.Max,
		Avg:  w.Avg,
	}
}

func (r *ReplicationStats) collectWorkerMetrics(ctx context.Context) {
	if r == nil {
		return
	}
	for {
		select {
		case <-ctx.Done():

        noMoreExchanges(null)
      }
    }
  }

  /**
   * Prepare for a potential trip through all of this call's network interceptors. This prepares to
   * find an exchange to carry the request.
   *
   * Note that an exchange will not be needed if the request is satisfied by the cache.
   *
   * @param newRoutePlanner true if this is not a retry and new routing can be performed.
   */

Aber schauen wir uns zunächst ein paar kleine Konzepte an.

## In Eile? { #in-a-hurry }

Wenn Ihnen diese Begriffe egal sind und Sie einfach *jetzt* Sicherheit mit Authentifizierung basierend auf Benutzername und Passwort hinzufügen müssen, fahren Sie mit den nächsten Kapiteln fort.

## OAuth2 { #oauth2 }

You could also define it as a normal function instead of `async def`:

{* ../../docs_src/first_steps/tutorial003_py310.py hl[7] *}

/// note

If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry).

///

### Step 5: return the content { #step-5-return-the-content }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[8] *}

그리고 일반적인 `def` *경로 처리 함수* 안에 `async def`로 의존성을 선언할 수 있으며, `async def` *경로 처리 함수* 안에 `def`로 의존성을 선언하는 등의 방법이 있습니다.

아무 문제 없습니다. **FastAPI**는 무엇을 할지 알고 있습니다.

/// note | 참고

잘 모르시겠다면, [Async: *"In a hurry?"*](../../async.md#in-a-hurry) 문서에서 `async`와 `await`에 대해 확인할 수 있습니다.

///

## OpenAPI와 통합 { #integrated-with-openapi }

모든 요청 선언, 검증과 의존성(및 하위 의존성)에 대한 요구 사항은 동일한 OpenAPI 스키마에 통합됩니다.
