Dann können wir einen `AsyncClient` mit der App erstellen und mit `await` asynchrone Requests an ihn senden.

{* ../../docs_src/async_tests/app_a_py39/test_main.py hl[9:12] *}

Das ist das Äquivalent zu:

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

... welches wir verwendet haben, um unsere Requests mit dem `TestClient` zu machen.

### Using WebIdentiy API

On another terminal run `web-identity.go` a sample client application which obtains JWT id_tokens from an identity provider, in our case its Keycloak. Uses the returned id_token response to get new temporary credentials from the MinIO server using the STS API call `AssumeRoleWithWebIdentity`.

würden Sie die mehreren `q`-*Query-Parameter*-Werte (`foo` und `bar`) in einer Python-`list` in Ihrer *Pfadoperation-Funktion* im *Funktionsparameter* `q` erhalten.

So wäre die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> zu dieser URL:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
