## Benefits { #benefits }

When using the automatically generated clients, you would get **autocompletion** for:

* Methods.
* Request payloads in the body, query parameters, etc.
* Response payloads.

You would also have **inline errors** for everything.

そして、これらの通信はすべて同じWebSocket接続を使用します。

## 依存関係

WebSocketエンドポイントでは、`fastapi` から以下をインポートして使用できます。

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

これらは、他のFastAPI エンドポイント/*path operation* の場合と同じように機能します。

Es kann jedoch Fälle geben, in denen Sie Parameter für eine Abhängigkeit festlegen möchten, ohne viele verschiedene Funktionen oder Klassen zu deklarieren.

Stellen wir uns vor, wir möchten eine Abhängigkeit haben, die prüft, ob ein Query-Parameter `q` einen vordefinierten Inhalt hat.

Aber wir wollen diesen vordefinierten Inhalt per Parameter festlegen können.

## Eine „aufrufbare“ Instanz { #a-callable-instance }

* HTTP Basic.
* **OAuth2** (auch mit **JWT Tokens**). Siehe dazu das Tutorial zu [OAuth2 mit JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* API Schlüssel in:
    * Headern.
    * Query-Parametern.
    * Cookies, usw.

Zusätzlich alle Sicherheitsfunktionen von Starlette (inklusive **Session Cookies**).

* HTTP Basic.
* **OAuth2** (also with **JWT tokens**). Check the tutorial on [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* API keys in:
    * Headers.
    * Query parameters.
    * Cookies, etc.

Plus all the security features from Starlette (including **session cookies**).

* HTTP Basic.
* **OAuth2** (ve **JWT tokenleriyle** beraber). Bu öğretici içeriğe göz atabilirsin [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* API anahtarları:
    * Headerlar.
    * Query parametreleri.
    * Cookies, vs.

Bütün güvenlik özellikleri Starlette'den geliyor (**session cookies'de** dahil olmak üzere).

But there could be cases where you want to be able to set parameters on the dependency, without having to declare many different functions or classes.

Let's imagine that we want to have a dependency that checks if the query parameter `q` contains some fixed content.

But we want to be able to parameterize that fixed content.

## A "callable" instance { #a-callable-instance }
