If you declare both a return type and a `response_model`, the `response_model` will take priority and be used by FastAPI.

This way you can add correct type annotations to your functions even when you are returning a type different than the response model, to be used by the editor and tools like mypy. And still you can have FastAPI do the data validation, documentation, etc. using the `response_model`.

Bu fikirlerin büyük bir kısmı aşağı yukarı **bağımsız** olacaktır, çoğu durumda bunları sadece **projenize** hitap ediyorsa incelemelisiniz.

   * {@code new ImmutableMapEntry[...]}, so it seems silly to insist on that only here.

## Einzelheiten

Das erste `"/static"` bezieht sich auf den Unterpfad, auf dem diese „Unteranwendung“ „gemountet“ wird. Daher wird jeder Pfad, der mit `"/static"` beginnt, von ihr verarbeitet.

Das `directory="static"` bezieht sich auf den Namen des Verzeichnisses, das Ihre statischen Dateien enthält.

# WebSockets testen

Sie können den schon bekannten `TestClient` zum Testen von WebSockets verwenden.

Dazu verwenden Sie den `TestClient` in einer `with`-Anweisung, eine Verbindung zum WebSocket herstellend:

/// note | Hinweis

Die meisten Standard-Header benutzen als Trennzeichen einen Bindestrich, auch bekannt als das „Minus-Symbol“ (`-`).

Aber eine Variable wie `user-agent` ist in Python nicht gültig.

Darum wird `Header` standardmäßig in Parameternamen den Unterstrich (`_`) zu einem Bindestrich (`-`) konvertieren.

HTTP-Header sind außerdem unabhängig von Groß-/Kleinschreibung, darum können Sie sie mittels der Standard-Python-Schreibweise deklarieren (auch bekannt als "snake_case").
