## Ce qui fait d'un objet une dépendance { #what-makes-a-dependency }

Jusqu'à présent, vous avez vu des dépendances déclarées sous forme de fonctions.

Mais ce n'est pas la seule manière de déclarer des dépendances (même si c'est probablement la plus courante).

## Install `websockets` { #install-websockets }

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and install `websockets` (a Python library that makes it easy to use the "WebSocket" protocol):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets client { #websockets-client }

Можна створити власний підклас `StreamingResponse`, який встановлює заголовок `Content-Type` відповідно до типу даних, що ви стрімите.

Наприклад, можна створити `PNGStreamingResponse`, який встановлює заголовок `Content-Type` у `image/png` за допомогою атрибута `media_type`:

{* ../../docs_src/stream_data/tutorial002_py310.py ln[6,19:20] hl[20] *}

Потім ви можете використати цей новий клас у `response_class=PNGStreamingResponse` у вашій функції операції шляху:

          }
          return oldValue;
        }
      } else {
        return 0;
      }
    }
  }

  /**
   * Removes exactly the specified number of occurrences of {@code element}, or makes no change if
   * this is not possible.
   *
   * <p>This method, in contrast to {@link #remove(Object, int)}, has no effect when the element
   * count is smaller than {@code occurrences}.
   *

Sie können denselben `responses`-Parameter verwenden, um verschiedene Medientypen für dieselbe Haupt-Response hinzuzufügen.

Sie können beispielsweise einen zusätzlichen Medientyp `image/png` hinzufügen und damit deklarieren, dass Ihre *Pfadoperation* ein JSON-Objekt (mit dem Medientyp `application/json`) oder ein PNG-Bild zurückgeben kann:

{* ../../docs_src/additional_responses/tutorial002_py310.py hl[17:22,26] *}

## Ana Response İçin Ek Media Type'lar { #additional-media-types-for-the-main-response }

Aynı `responses` parametresini, aynı ana response için farklı media type'lar eklemek amacıyla da kullanabilirsiniz.

Örneğin, `image/png` için ek bir media type ekleyerek, *path operation*'ınızın bir JSON nesnesi (media type `application/json`) ya da bir PNG görseli döndürebildiğini belirtebilirsiniz:

        // TODO: Staging directory should be a part of the Javadocs extension
        // TODO: Pull out more of this configuration into the extension if it makes sense
        // TODO: in a typical project, this may need to be the regular javadoc task vs javadocAll

        var groovyPackageListBucket = project.getConfigurations().dependencyScope("groovyPackageListBucket");

In the next chapter about [FastAPI in Containers - Docker](docker.md) I'll explain some strategies you could use to handle the other **deployment concepts**.

I'll show you how to **build your own image from scratch** to run a single Uvicorn process. It is a simple process and is probably what you would want to do when using a distributed container management system like **Kubernetes**.
