Imaginons que vous ayez votre API de **backend** sur un certain domaine.

Et vous avez un **frontend** sur un autre domaine ou dans un chemin différent du même domaine (ou dans une application mobile).

Et vous voulez que le **frontend** puisse s'authentifier auprès du **backend**, en utilisant un **username** et un **password**.

Nous pouvons utiliser **OAuth2** pour construire cela avec **FastAPI**.

        SmbComTransactionResponse r2 = (SmbComTransactionResponse) d.nextElement();
        assertSame(d, r2, "Subsequent calls still return same instance");
        assertFalse(d.getIsPrimary(), "isPrimary remains false after subsequent call");
    }

    @Test
    public void toString_doesNotThrow() {
        DummyResponse d = new DummyResponse();
        String s = d.toString();

/// note

Previously, it was recommended to use `WSGIMiddleware` from `fastapi.middleware.wsgi`, but it is now deprecated.

It’s advised to use the `a2wsgi` package instead. The usage remains the same.

Just ensure that you have the `a2wsgi` package installed and import `WSGIMiddleware` correctly from `a2wsgi`.
