Der Parameter `response_class` wird auch verwendet, um den „Medientyp“ der Response zu definieren.

In diesem Fall wird der HTTP-Header `Content-Type` auf `application/json` gesetzt.

E se você olhar o esquema OpenAPI resultante (na rota `/openapi.json` da sua API), você verá que a sua extensão também faz parte da *operação de rota* específica:

```JSON hl_lines="22"
{
    "openapi": "3.1.0",
    "info": {
        "title": "FastAPI",
        "version": "0.1.0"
    },
    "paths": {
        "/items/": {
            "get": {
                "summary": "Read Items",

			defer mu.Unlock()

			allMerged = dataUsageCache{Info: dataUsageCacheInfo{Name: dataUsageRoot}}
			for _, info := range results {
				if info.Info.LastUpdate.IsZero() {
					// Not filled yet.
					return
				}
				allMerged.merge(info)
			}
			if allMerged.root() != nil && allMerged.Info.LastUpdate.After(lastUpdate) {
				updates <- allMerged.dui(allMerged.Info.Name, allBuckets)
				lastUpdate = allMerged.Info.LastUpdate

        } catch (final Exception e) {
            appendException(buf, e).append(',');
        }

        appendTimestamp(buf);
        buf.append('}');

        if (logger.isInfoEnabled()) {
            logger.info(buf.toString());
        }
    }

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Wenn Sie dann zu den URLs unter `/openapi.json`, `/docs` oder `/redoc` gehen, erhalten Sie lediglich einen `404 Not Found`-Fehler, wie:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Luego, si vas a las URLs en `/openapi.json`, `/docs`, o `/redoc`, solo obtendrás un error `404 Not Found` como:

```JSON
{

Así que, la línea:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

no se ejecutará.

Следовательно, строка:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

не будет выполнена.
