Lorsque vous utilisez un `response_model` ou un type de retour, FastAPI n'utilise ni le `jsonable_encoder` pour convertir les données (ce qui serait plus lent) ni la classe `JSONResponse`.

### Run the App { #run-the-app }

You can run the app:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Then go to the `/docs` UI, you will see that **FastAPI** is using these **models** to **document** the API, and it will use them to **serialize** and **validate** the data too.

Sie können die App ausführen:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## SSE avec POST { #sse-with-post }

SSE fonctionne avec **n’importe quelle méthode HTTP**, pas seulement `GET`.

C’est utile pour des protocoles comme [MCP](https://modelcontextprotocol.io) qui diffusent des SSE via `POST` :

{* ../../docs_src/server_sent_events/tutorial005_py310.py hl[14] *}

## Détails techniques { #technical-details }

FastAPI met en œuvre certaines bonnes pratiques SSE prêtes à l’emploi.

## Prerequisites

Configure and install keycloak server by following [Keycloak Installation Guide](https://www.keycloak.org/docs/latest/server_installation/#installing-the-software).
For a quick installation, docker-compose reference configs are also available on the [Keycloak GitHub](https://github.com/keycloak/keycloak-containers/tree/main/docker-compose-examples).

### Configure Keycloak Realm

- Go to Clients

	// to use some ANSI control escapes to cursor color state
	// and freely move in the screen.
	for line := range strings.SplitSeq(errMsg, "\n") {
		if len(line) == 0 {
			// No more text to print, just quit.
			break
		}

		// Save the attributes of the current cursor helps
		// us save the text color of the passed error message
