# WSGI inkludieren – Flask, Django und andere

Sie können WSGI-Anwendungen mounten, wie Sie es in [Unteranwendungen – Mounts](sub-applications.md){.internal-link target=_blank}, [Hinter einem Proxy](behind-a-proxy.md){.internal-link target=_blank} gesehen haben.

Dazu können Sie die `WSGIMiddleware` verwenden und damit Ihre WSGI-Anwendung wrappen, zum Beispiel Flask, Django usw.

## `WSGIMiddleware` verwenden

Sie müssen `WSGIMiddleware` importieren.

# Adicionando WSGI - Flask, Django, entre outros

Como você viu em [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank} e [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank}, você pode **"montar"** aplicações WSGI.

Para isso, você pode utilizar o `WSGIMiddleware` para encapsular a sua aplicação WSGI, como por exemplo Flask, Django, etc.

## Usando o `WSGIMiddleware`

Você precisa importar o `WSGIMiddleware`.

## Anwendungsfälle

Einige Anwendungsfälle sind:

* Konvertieren von Nicht-JSON-Requestbodys nach JSON (z. B. <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Dekomprimierung gzip-komprimierter Requestbodys.
* Automatisches Loggen aller Requestbodys.

## Handhaben von benutzerdefinierten Requestbody-Kodierungen

사용자 정의 헤더는 <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">'X-' 접두사를 사용</a>하여 추가할 수 있습니다.

그러나 만약 클라이언트의 브라우저에서 볼 수 있는 사용자 정의 헤더를 가지고 있다면, 그것들을 CORS 설정([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank})에 <a href="https://www.starlette.io/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette CORS 문서</a>에 명시된 `expose_headers` 매개변수를 이용하여 헤더들을 추가하여야합니다.

        this.targetClass = targetClass;
        this.methodName = methodName;
        this.argTypes = argTypes;
    }

    /**
     * Returns the target class.
     *
     * @return the target class
     */
    public Class<?> getTargetClass() {
        return targetClass;
    }

    /**
     * Returns the method name.
     *
     * @return the method name

## **Typer**, the FastAPI of CLIs

# Веб-сокеты

Вы можете использовать <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">веб-сокеты</a> в **FastAPI**.

## Установка `WebSockets`

Убедитесь, что [виртуальная среда](../virtual-environments.md){.internal-link target=_blank} создана, активируйте её и установите `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

### Kontrol Edelim

Tarayıcınızı açıp <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a> bağlantısına gidin.

Şu şekilde bir JSON yanıtı ile karşılaşacağız:

```JSON
{"message": "Hello World"}
```
