* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

Diese funktionieren auf die gleiche Weise wie für andere FastAPI-Endpunkte/*Pfadoperationen*:

/// info | Info

Da es sich um einen WebSocket handelt, macht es keinen Sinn, eine `HTTPException` auszulösen, stattdessen lösen wir eine `WebSocketException` aus.

**FastAPI** knows what to do in each case and how to reuse the same object, so that all the background tasks are merged together and are run in the background afterwards:


{* ../../docs_src/background_tasks/tutorial002_an_py310.py hl[13,15,22,25] *}


In this example, the messages will be written to the `log.txt` file *after* the response is sent.

If there was a query in the request, it will be written to the log in a background task.

O **FastAPI** sabe o que fazer em cada caso e como reutilizar o mesmo objeto, de forma que todas as tarefas em segundo plano sejam combinadas e executadas em segundo plano depois:


{* ../../docs_src/background_tasks/tutorial002_an_py310.py hl[13,15,22,25] *}

Neste exemplo, as mensagens serão escritas no arquivo `log.txt` *após* o envio da resposta.

Se houver uma query na request, ela será registrada em uma tarefa em segundo plano.

Они работают так же, как и в других FastAPI эндпоинтах/*операциях пути*:

/// info | Примечание

В веб-сокете вызывать `HTTPException` не имеет смысла. Вместо этого нужно использовать `WebSocketException`.

WebSocket 엔드포인트에서 `fastapi`에서 다음을 가져와 사용할 수 있습니다:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

이들은 다른 FastAPI 엔드포인트/*경로 작동*과 동일하게 동작합니다:

{* ../../docs_src/websockets/tutorial002_an_py310.py hl[68:69,82] *}

/// info | 정보

WebSocket에서는 `HTTPException`을 발생시키는 것이 적합하지 않습니다. 대신 `WebSocketException`을 발생시킵니다.

    # TODO: remove when updating SQL tutorial to use new lifespan API

* `Depends`

They work the same way as for other FastAPI endpoints/*path operations*:

/// info

As this is a WebSocket it doesn't really make sense to raise an `HTTPException`, instead we raise a `WebSocketException`.

Завдяки цьому ми отримуємо підтримку інструментів — від редакторів і mypy, оскільки цей код є коректним з точки зору типів, — але ми також отримуємо фільтрацію даних від FastAPI.
