## Utiliser `Depends` et autres { #using-depends-and-others }

Dans les endpoints WebSocket, vous pouvez importer depuis `fastapi` et utiliser :

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

Ils fonctionnent de la même manière que pour les autres endpoints/*chemins d'accès* FastAPI :

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

Wir werden nun eine einfache Abhängigkeit verwenden, um einen benutzerdefinierten `X-Token`-Header zu lesen:

{* ../../docs_src/bigger_applications/app_an_py310/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | Tipp

Um dieses Beispiel zu vereinfachen, verwenden wir einen erfundenen Header.

<h3 id="data-offsets">Interacting with Go types and constants</h3>

<p>
If a package has any .s files, then <code>go build</code> will direct
the compiler to emit a special header called <code>go_asm.h</code>,
which the .s files can then <code>#include</code>.
The file contains symbolic <code>#define</code> constants for the
offsets of Go struct fields, the sizes of Go struct types, and most
