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

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

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

/// info | Información

Como esto es un WebSocket no tiene mucho sentido lanzar un `HTTPException`, en su lugar lanzamos un `WebSocketException`.

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

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

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

/// info

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

    long timeoutNanos = unit.toNanos(timeout);
    if (timeoutNanos <= OverflowAvoidingLockSupport.MAX_NANOSECONDS_THRESHOLD) {
      return super.get(timeout, unit);
    }
    // Waiting 68 years should be enough for any program.
    return super.get(
        min(timeoutNanos, OverflowAvoidingLockSupport.MAX_NANOSECONDS_THRESHOLD), NANOSECONDS);
  }

* `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.
