# Incluyendo WSGI - Flask, Django, otros

Puedes montar aplicaciones WSGI como viste con [Sub Aplicaciones - Mounts](sub-applications.md){.internal-link target=_blank}, [Detrás de un Proxy](behind-a-proxy.md){.internal-link target=_blank}.

Para eso, puedes usar `WSGIMiddleware` y usarlo para envolver tu aplicación WSGI, por ejemplo, Flask, Django, etc.

## Usando `WSGIMiddleware`

Necesitas importar `WSGIMiddleware`.

## Instalacja

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

Na serwerze produkcyjnym będziesz także potrzebował serwera ASGI, np. <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> lub <a href="https://github.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>.

# WSGI - Flask, Django ve Daha Fazlasını FastAPI ile Kullanma

WSGI uygulamalarını [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank}, [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank} bölümlerinde gördüğünüz gibi bağlayabilirsiniz.

Bunun için `WSGIMiddleware` ile Flask, Django vb. WSGI uygulamanızı sarmalayabilir ve FastAPI'ya bağlayabilirsiniz.

## `WSGIMiddleware` Kullanımı

`WSGIMiddleware`'ı projenize dahil edin.

import java.util.concurrent.TimeoutException;
import org.jspecify.annotations.Nullable;

 *

    reverse(array, fromIndex, toIndex);
  }

  /**
   * Returns a fixed-size list backed by the specified array, similar to {@link
   * Arrays#asList(Object[])}. The list supports {@link List#set(int, Object)}, but any attempt to
   * set a value to {@code null} will result in a {@link NullPointerException}.
   *
   * <p>The returned list maintains the values, but not the identities, of {@code Character} objects
