* `headers` – Ein `dict` von Strings.
* `media_type` – Ein `str`, der den Medientyp angibt. Z. B. `"text/html"`.

FastAPI (eigentlich Starlette) fügt automatisch einen Content-Length-Header ein. Außerdem wird es einen Content-Type-Header einfügen, der auf dem `media_type` basiert, und für Texttypen einen Zeichensatz (charset) anfügen.

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

* `headers` - A `dict` of strings.
* `media_type` - A `str` giving the media type. E.g. `"text/html"`.

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the `media_type` and appending a charset for text types.

### `HTMLResponse` { #htmlresponse }

SSE, HTTP üzerinden sunucudan istemciye veri akışı için bir standarttır.

Her olay, aralarında boş satırlar bulunan ve `data`, `event`, `id` ve `retry` gibi "alanlar" içeren küçük bir metin bloğudur.

Şuna benzer:

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```

Ardından bunu bir attribute’un tipi olarak kullanabiliriz:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

Bu da **FastAPI**’nin aşağıdakine benzer bir body bekleyeceği anlamına gelir:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {

Çıktıda, şuna benzer bir satır göreceksiniz:

```hl_lines="4"
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

Bu satır, uygulamanızın yerel makinenizde hangi URL'de sunulduğunu gösterir.

                container.addComponent(mock(Maven.class), "org.apache.maven.Maven");

                ((DefaultPlexusContainer) container)
                        .addPlexusInjector(Collections.emptyList(), binder -> binder.bind(EventSpyDispatcher.class)
                                .toInstance(eventSpyDispatcherMock));
            }
        };

        CliRequest cliRequest = new CliRequest(new String[] {}, null);
