### CORS preflight requests { #cors-preflight-requests }

These are any `OPTIONS` request with `Origin` and `Access-Control-Request-Method` headers.

In this case the middleware will intercept the incoming request and respond with appropriate CORS headers, and either a `200` or `400` response for informational purposes.

### Simple requests { #simple-requests }

Enforces that all incoming requests must either be `https` or `wss`.

Any incoming request to `http` or `ws` will be redirected to the secure scheme instead.

{* ../../docs_src/advanced_middleware/tutorial001.py hl[2,6] *}

## `TrustedHostMiddleware` { #trustedhostmiddleware }

Enforces that all incoming requests have a correctly set `Host` header, in order to guard against HTTP Host Header attacks.

También defines de alguna manera en qué **momentos** tu aplicación enviará esas requests o eventos.

Y **tus usuarios** definen de alguna manera (por ejemplo en un panel web en algún lugar) el **URL** donde tu aplicación debería enviar esas requests.

Toda la **lógica** sobre cómo registrar los URLs para webhooks y el código para realmente enviar esas requests depende de ti. Lo escribes como quieras en **tu propio código**.

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

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

This is the equivalent to:

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

...that we used to make our requests with the `TestClient`.

/// tip

///

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

{* ../../docs_src/async_tests/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.

**FastAPI** насправді не є альтернативою **Requests**. Сфера їх застосування дуже різна.

Насправді цілком звична річ використовувати Requests *всередині* програми FastAPI.

Але все ж FastAPI черпав натхнення з Requests.
