## Usando `Depends` e outros { #using-depends-and-others }

Nos endpoints WebSocket você pode importar do `fastapi` e usar:

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

Eles funcionam da mesma forma que para outros endpoints FastAPI/*operações de rota*:

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

/// info | Informação

`http` 또는 `ws`로 들어오는 모든 요청은 대신 보안 스킴으로 리디렉션됩니다.

{* ../../docs_src/advanced_middleware/tutorial001_py310.py hl[2,6] *}

## `TrustedHostMiddleware` { #trustedhostmiddleware }

HTTP Host Header 공격을 방어하기 위해, 들어오는 모든 요청에 올바르게 설정된 `Host` 헤더가 있어야 하도록 강제합니다.

{* ../../docs_src/advanced_middleware/tutorial002_py310.py hl[2,6:8] *}

다음 인자들을 지원합니다:

          + ")") : "(cache)";
      int responseCode = response.code();

      System.out.printf("%03d: %s %s%n", responseCode, url, responseSource);

      String contentType = response.header("Content-Type");
      if (responseCode != 200 || contentType == null) {
        return;
      }

      MediaType mediaType = MediaType.parse(contentType);

Puedes añadir código que se ejecute con la `request`, antes de que cualquier *path operation* la reciba.

Y también después de que se genere la `response`, antes de devolverla.

Por ejemplo, podrías añadir un custom header `X-Process-Time` que contenga el tiempo en segundos que tomó procesar la request y generar una response:

{* ../../docs_src/middleware/tutorial001_py310.py hl[10,12:13] *}

	case TransitionAction, TransitionVersionAction:
		w.Header()[xhttp.MinIOTransition] = []string{

## Usando `Depends` y otros { #using-depends-and-others }

En endpoints de WebSocket puedes importar desde `fastapi` y usar:

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

Funcionan de la misma manera que para otros endpoints de FastAPI/*path operations*:

                When `True` (the default), requests with a body that do not include
                a `Content-Type` header will **not** be parsed as JSON.

                This prevents potential cross-site request forgery (CSRF) attacks
                that exploit the browser's ability to send requests without a
                Content-Type header, bypassing CORS preflight checks. In particular

## Verwendung von `Depends` und anderen { #using-depends-and-others }

In WebSocket-Endpunkten können Sie Folgendes aus `fastapi` importieren und verwenden:

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

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