在這個範例中我們使用了自訂的（虛構的）標頭 `X-Key` 與 `X-Token`。

但在實際情況下，當你實作安全機制時，使用整合的 [Security utilities（下一章）](../security/index.md) 會獲得更多好處。

///

## 依賴的錯誤與回傳值 { #dependencies-errors-and-return-values }

你可以使用與平常相同的依賴函式。

### 依賴的需求 { #dependency-requirements }

它們可以宣告請求需求（例如標頭（headers））或其他子依賴：

Для решения этой задачи, вероятно, намного проще использовать `body` в пользовательском обработчике `RequestValidationError` ([Обработка ошибок](../tutorial/handling-errors.md#use-the-requestvalidationerror-body)).

Но этот пример всё равно актуален и показывает, как взаимодействовать с внутренними компонентами.

Isso seria parecido com:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Return some error
    ...
```

Porém, ao utilizar o `secrets.compare_digest()`, isso estará seguro contra um tipo de ataque chamado "timing attacks".

### Ataques de Temporização { #timing-attacks }

Mas o que é um "timing attack"?

	transport := s.NewHTTPTransportWithTimeout(1 * time.Minute)

		c, err := certs.NewManager(ctx, clientCert, clientKey, tls.LoadX509KeyPair)
		if err != nil {
			return nil, err
