Вы можете создать пользовательский подкласс `StreamingResponse`, который устанавливает HTTP-заголовок `Content-Type` в тип данных, которые вы стримите.

Например, вы можете создать `PNGStreamingResponse`, который устанавливает HTTP-заголовок `Content-Type` в `image/png` с помощью атрибута `media_type`:

                                    "type": "integer",
                                },
                            },
                        ],
                        "requestBody": {
                            "content": {
                                "application/json": {
                                    "schema": {
                                        "$ref": "#/components/schemas/Body_update_item_items__item_id__put",

Yukarıdaki örneklerde veri baytları akıtıldı, ancak response'ta bir `Content-Type` header'ı yoktu; bu nedenle istemci hangi tür veriyi aldığını bilmiyordu.

Akıttığınız veri türüne uygun `Content-Type` header'ını ayarlayan, `StreamingResponse`'tan türetilmiş özel bir alt sınıf (subclass) oluşturabilirsiniz.

Örneğin, `media_type` özniteliğini kullanarak `Content-Type` header'ını `image/png` olarak ayarlayan bir `PNGStreamingResponse` oluşturabilirsiniz:

* `.gitignore`: the name of the file where the text should be written

And `*` for Git means "everything". So, it will ignore everything in the `.venv` directory.

That command will create a file `.gitignore` with the content:

```gitignore
*
```
