Wenn Sie jedoch benutzerdefinierte Header haben, die ein Client in einem Browser sehen können soll, müssen Sie diese zu Ihrer CORS-Konfiguration hinzufügen (weitere Informationen finden Sie unter [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md)), unter Verwendung des Parameters `expose_headers`, dokumentiert in [Starlettes CORS-Dokumentation](https://www.starlette.dev/middleware/#corsmiddleware)....

the `X-` prefix](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

But if you have custom headers that you want a client in a browser to be able to see, you need to add them to your CORS configurations (read more in [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md)), using the parameter `expose_headers` documented in [Starlette's CORS docs](https://www.starlette.dev/middleware/#corsmiddleware)....

Das ist dank **Pydantic** ebenfalls möglich, da es [„`dataclasses` intern unterstützt“](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel).

Auch wenn im obigen Code Pydantic nicht explizit vorkommt, verwendet FastAPI Pydantic, um diese Standard-Datenklassen in Pydantics eigene Variante von Datenklassen zu konvertieren.

Und natürlich wird das gleiche unterstützt:

* Datenvalidierung
