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

{* ../../docs_src/security/tutorial007_an_py310.py hl[1,12:24] *}

Это было бы похоже на:

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

Luego podemos usar `secrets.compare_digest()` para asegurar que `credentials.username` es `"stanleyjobson"`, y que `credentials.password` es `"swordfish"`.

{* ../../docs_src/security/tutorial007_an_py310.py hl[1,12:24] *}

Esto sería similar a:

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

Потім ми можемо використати `secrets.compare_digest()`, щоб упевнитися, що `credentials.username` дорівнює `"stanleyjobson"`, а `credentials.password` дорівнює `"swordfish"`.

{* ../../docs_src/security/tutorial007_an_py310.py hl[1,12:24] *}

Це було б подібно до:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Поверніть якусь помилку
    ...
```

Dann können wir `secrets.compare_digest()` verwenden, um sicherzustellen, dass `credentials.username` `"stanleyjobson"` und `credentials.password` `"swordfish"` ist.

Dies wäre das gleiche wie:

    # Einen Error zurückgeben

Para transmitir JSON Lines com FastAPI, em vez de usar `return` na sua *função de operação de rota*, use `yield` para produzir cada item em sequência.

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[24] *}

Se cada item JSON que você quer enviar de volta for do tipo `Item` (um modelo Pydantic) e a função for assíncrona, você pode declarar o tipo de retorno como `AsyncIterable[Item]`:
