تمام طرح های امنیتی در OpenAPI تعریف شده اند، از جمله:

* .
* **OAuth2** (همچنین با **JWT tokens**). آموزش را در [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=\_blank} مشاهده کنید.

## Einfache Verwendung

Bütün güvenlik şemaları OpenAPI'da tanımlanmış durumda, kapsadıkları:

* 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.

Wszystkie schematy bezpieczeństwa zdefiniowane w OpenAPI, w tym:

* Podstawowy protokół HTTP.
* **OAuth2** (również z **tokenami JWT**). Sprawdź samouczek [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* Klucze API w:
    * Nagłówkach.
    * Parametrach zapytań.
    * Ciasteczkach, itp.

## Caso de Uso Simples

### Was sind „Kontextmanager“

„Kontextmanager“ (Englisch „Context Manager“) sind bestimmte Python-Objekte, die Sie in einer `with`-Anweisung verwenden können.

Beispielsweise können Sie <a href="https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files" class="external-link" target="_blank">`with` verwenden, um eine Datei auszulesen</a>:

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
