## Verifique o usuário

Aqui está um exemplo mais completo.

Utilize uma dependência para verificar se o usuário e a senha estão corretos.

Para isso, utilize o módulo padrão do Python <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a> para verificar o usuário e senha.

# Веб-сокеты

Вы можете использовать <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">веб-сокеты</a> в **FastAPI**.

## Установка `WebSockets`

Убедитесь, что [виртуальная среда](../virtual-environments.md){.internal-link target=_blank} создана, активируйте её и установите `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

次のようなJSONレスポンスが表示されます:

```JSON
{"message": "Hello World"}
```

自動生成された対話的APIドキュメントが表示されます (<a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>で提供):

Це можна досягти за допомогою <a href="https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator" class="external-link" target="_blank">Pydantic's `AfterValidator`</a> в середині `Annotated`.

/// tip | Підказка

FastAPI використовує `.dict()` моделі Pydantic з <a href="https://docs.pydantic.dev/1.10/usage/exporting_models/#modeldict" class="external-link" target="_blank">параметром `exclude_unset`</a>, щоб досягти цього.

Typically HTTP headers work like a `Map<String, String>`: each field has one value or none. But some headers permit multiple values, like Guava's [Multimap](https://guava.dev/releases/23.0/api/docs/com/google/common/collect/Multimap.html). For example, it's legal and common for an HTTP response to supply multiple `Vary` headers. OkHttp's APIs attempt to make both cases comfortable.
