For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:

{* ../../docs_src/middleware/tutorial001_py39.py hl[10,12:13] *}

/// tip

Затем можно использовать `secrets.compare_digest()`, чтобы убедиться, что `credentials.username` равен `"stanleyjobson"`, а `credentials.password` — `"swordfish"`.

{* ../../docs_src/security/tutorial007_an_py39.py hl[1,12:24] *}

Это было бы похоже на:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Вернуть ошибку
    ...
```

          k2 ^= (long) toUnsignedInt(bb.get(12)) << 32; // fall through
        case 12:
          k2 ^= (long) toUnsignedInt(bb.get(11)) << 24; // fall through
        case 11:
          k2 ^= (long) toUnsignedInt(bb.get(10)) << 16; // fall through
        case 10:
          k2 ^= (long) toUnsignedInt(bb.get(9)) << 8; // fall through
        case 9:
          k2 ^= (long) toUnsignedInt(bb.get(8)); // fall through
        case 8:

		cfg.Delay, cfg.MaxWait, cfg.Cycle = 1, 100*time.Millisecond, time.Minute
	case "default":

	case "slowest":
		cfg.Delay, cfg.MaxWait, cfg.Cycle = 100, 15*time.Second, 30*time.Minute
	default:
		return cfg, fmt.Errorf("unknown '%s' value", speed)
	}

	return cfg, nil
}

Por exemplo, você pode adicionar um cabeçalho personalizado `X-Process-Time` contendo o tempo em segundos que levou para processar a solicitação e gerar uma resposta:

{* ../../docs_src/middleware/tutorial001_py39.py hl[10,12:13] *}

/// tip | Dica

Наприклад, Ви можете додати власний заголовок `X-Process-Time`, який міститиме час у секундах, який витратився на обробку запиту та генерацію відповіді:

{* ../../docs_src/middleware/tutorial001.py hl[10,12:13] *}


/// tip | Підказка

Then we can use `secrets.compare_digest()` to ensure that `credentials.username` is `"stanleyjobson"`, and that `credentials.password` is `"swordfish"`.

{* ../../docs_src/security/tutorial007_an_py39.py hl[1,12:24] *}

This would be similar to:

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