Luego podemos crear un `AsyncClient` con la app y enviar requests asíncronos a ella, usando `await`.

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

Esto es equivalente a:

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

...que usábamos para hacer nuestros requests con el `TestClient`.

/// tip | Consejo

MinIO server allows to throttle incoming requests:

- limit the number of active requests allowed across the cluster
- limit the wait duration for each request in the queue

These values are enabled using server's configuration or environment variables.

## Examples

It uses a single two-way connection to send and receive messages between servers.

It includes built in muxing of concurrent requests as well as congestion handling for streams.

Requests can be "Single Payload" or "Streamed".

Use the MinIO Grid for:

* Small, frequent requests with low latency requirements.
* Long-running requests with small/medium payloads.

Do *not* use the MinIO Grid for:

* Large payloads.

**FastAPI** на самом деле не альтернатива **Requests**. Их области применения очень различны.

Обычно Requests используют даже внутри приложения FastAPI.

И всё же **FastAPI** во многом вдохновлялся Requests.

## Casos de uso { #use-cases }

Algunos casos de uso incluyen:

* Convertir cuerpos de requests no-JSON a JSON (por ejemplo, <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Descomprimir cuerpos de requests comprimidos con gzip.
* Registrar automáticamente todos los request bodies.

	m.singleResp = false
	m.RecvSeq = m.SendSeq // Sync
	if cap(requests) > 0 {
		m.outBlock = make(chan struct{}, cap(requests))
	}
	msg := message{
		Op:         OpConnectMux,
		Handler:    h,
		Payload:    payload,
		DeadlineMS: uint32(m.deadline.Milliseconds()),
	}
	msg.setZeroPayloadFlag()
	if requests == nil {
		msg.Flags |= FlagEOF
	}
	if m.subroute != nil {

Wenn Sie den Callback selbst implementieren, können Sie beispielsweise <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> oder <a href="https://requests.readthedocs.io/" class="external-link" target="_blank">Requests</a> verwenden.

### 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.
