E todas elas usarão a mesma conexão WebSocket.

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

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

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

/// info | Informação

`Query`, `Path` e outras classes que você verá depois são subclasses de uma classe comum `Param`.

Todas elas compartilham os mesmos parâmetros para validação adicional e metadados que você viu.

///

/// note | Detalhes Técnicos

Quando você importa `Query`, `Path` e outras de `fastapi`, elas são na verdade funções.

        // Arrange
        SmbFile dest = mock(SmbFile.class);
        SmbFileHandleImpl handle = mock(SmbFileHandleImpl.class);
        SmbAuthException authEx = new SmbAuthException("denied");

        when(dest.openUnshared(anyInt(), anyInt(), anyInt(), anyInt(), anyInt())).thenThrow(authEx) // first attempt fails with auth
                .thenReturn(handle); // second attempt succeeds

        // dest currently has READONLY attribute set

# GraphQL { #graphql }

Comme **FastAPI** est basé sur la norme **ASGI**, il est très facile d'intégrer toute bibliothèque **GraphQL** également compatible avec ASGI.

Vous pouvez combiner des *chemins d'accès* FastAPI classiques avec GraphQL dans la même application.

/// tip | Astuce

**GraphQL** résout des cas d'utilisation très spécifiques.

Il présente des **avantages** et des **inconvénients** par rapport aux **API web** classiques.
