Here is the reference for it and its parameters.

You can import it directly from `fastapi`:

```python
from fastapi import Depends
```

::: fastapi.Depends

## `Security()`

For many scenarios, you can handle security (authorization, authentication, etc.) with dependencies, using `Depends()`.

But when you want to also declare OAuth2 scopes, you can use `Security()` instead of `Depends()`.

                        withPsiEntry("psi", psi, analysisSession::getModule)
                    }
            }

            // Specially handle @ExtensionFunctionType
            if (dispatchReceiver?.resolvedType?.isExtensionFunctionType == true) {
                firstArgIsExtensionReceiver = true
            }

*   Updates `libjpeg-turbo` to `2.0.5` to handle
    [CVE-2020-13790](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-13790).
*   Updates `junit` to `4.13.1` to handle
    [CVE-2020-15250](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-15250).
*   Updates `PCRE` to `8.44` to handle
    [CVE-2019-20838](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-20838)
    and

   * until one is ready. If there are no ready queues, or if other threads have everything under
   * control this will return null. If there is more than a single task ready to execute immediately
   * this will start another thread to handle that work.
   */
  fun awaitTaskToRun(): Task? {
    lock.assertHeld()

    while (true) {
      if (readyQueues.isEmpty()) {
        return null // Nothing to do.
      }

    Those details are implementation specific.

    For OAuth2 they are just strings.

## Code to get the `username` and `password`

Now let's use the utilities provided by **FastAPI** to handle this.

### `OAuth2PasswordRequestForm`

First, import `OAuth2PasswordRequestForm`, and use it as a dependency with `Depends` in the *path operation* for `/token`:

Daha yeni başladık ama çalışma mantığını çoktan anlamış oldunuz.

Şimdi aşağıdaki satırı değiştirmeyi deneyin:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...bundan:

```Python
        ... "item_name": item.name ...
```

...buna:

```Python
        ... "item_price": item.price ...
```

## Handling disconnections and multiple clients

When a WebSocket connection is closed, the `await websocket.receive_text()` will raise a `WebSocketDisconnect` exception, which you can then catch and handle like in this example.
