/// tip

Note that the test function is now `async def` instead of just `def` as before when using the `TestClient`.

///

Then we can create an `AsyncClient` with the app, and send async requests to it, using `await`.

This is the equivalent to:

```Python
response = client.get('/')
```

Wenn es Hintergrundtasks gab (dies wird später im [Hintergrundtasks](background-tasks.md){.internal-link target=_blank}-Abschnitt behandelt), werden sie *nach* allen Middlewares ausgeführt.

## Eine Middleware erstellen { #create-a-middleware }

Um eine Middleware zu erstellen, verwenden Sie den Dekorator `@app.middleware("http")` über einer Funktion.

Die Middleware-Funktion erhält:

**FastAPI** creará el objeto de tipo `BackgroundTasks` por ti y lo pasará como ese parámetro.

## Crear una función de tarea { #create-a-task-function }

Crea una función para que se ejecute como la tarea en segundo plano.

Es solo una función estándar que puede recibir parámetros.

Then, when you type that username and password, the browser sends them in the header automatically.

## Simple HTTP Basic Auth { #simple-http-basic-auth }

* Import `HTTPBasic` and `HTTPBasicCredentials`.
* Create a "`security` scheme" using `HTTPBasic`.
* Use that `security` with a dependency in your *path operation*.
* It returns an object of type `HTTPBasicCredentials`:
    * It contains the `username` and `password` sent.
