### Configure Casdoor

- Go to Applications
  - Create or use an existing Casdoor application
  - Edit the application
    - Copy `Client ID` and `Client secret`
    - Add your redirect url (callback url) to `Redirect URLs`
    - Save

- Go to Users
  - Edit the user

/// warning | Uyarı

*Yol operasyonları* içerisinde birden fazla `Form` parametresi tanımlayabilirsiniz ancak bunlarla birlikte JSON verisi kabul eden `Body` alanları tanımlayamazsınız çünkü bu durumda istek gövdesi `application/json` yerine `application/x-www-form-urlencoded` ile kodlanmış olur.

Bu **FastAPI**'ın getirdiği bir kısıtlama değildir, HTTP protokolünün bir parçasıdır.

Tout d'abord il faut "épingler" la version de **FastAPI** que vous utilisez à la dernière version dont vous savez
qu'elle fonctionne correctement pour votre application.

Par exemple, disons que vous utilisez la version `0.45.0` dans votre application.

Si vous utilisez un fichier `requirements.txt`, vous pouvez spécifier la version avec :

```txt
fastapi==0.45.0
```

ce qui signifierait que vous utiliseriez exactement la version `0.45.0`.

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.

Or you might have a native mobile application that communicates with your WebSocket backend directly, in native code.

Or you might have any other way to communicate with the WebSocket endpoint.
