Using a relative URL is important to make sure your application keeps working even in an advanced use case like [Behind a Proxy](../../advanced/behind-a-proxy.md){.internal-link target=_blank}.

# WSGI 포함하기 - Flask, Django 그 외

[서브 응용 프로그램 - 마운트](sub-applications.md){.internal-link target=_blank}, [프록시 뒤편에서](behind-a-proxy.md){.internal-link target=_blank}에서 보았듯이 WSGI 응용 프로그램들을 다음과 같이 마운트 할 수 있습니다.

`WSGIMiddleware`를 사용하여 WSGI 응용 프로그램(예: Flask, Django 등)을 감쌀 수 있습니다.

## `WSGIMiddleware` 사용하기

`WSGIMiddleware`를 불러와야 합니다.

그런 다음, WSGI(예: Flask) 응용 프로그램을 미들웨어로 포장합니다.

그 후, 해당 경로에 마운트합니다.

    get() = socketAddress.port

  public val hostName: String
    get() = socketAddress.address.hostName

  /** Returns the address of this server, to connect to it as an HTTP proxy. */
  public val proxyAddress: Proxy
    get() = Proxy(Proxy.Type.HTTP, socketAddress)

  /**

Die Verwendung einer relativen URL ist wichtig, um sicherzustellen, dass Ihre Anwendung auch in einem fortgeschrittenen Anwendungsfall, wie [hinter einem Proxy](../../advanced/behind-a-proxy.md){.internal-link target=_blank}, weiterhin funktioniert.

#### TLS Termination Proxyの裏側

Nginx や Traefik のような TLS Termination Proxy (ロードバランサ) の後ろでコンテナを動かしている場合は、`--proxy-headers`オプションを追加します。

このオプションは、Uvicornにプロキシ経由でHTTPSで動作しているアプリケーションに対して、送信されるヘッダを信頼するよう指示します。

```Dockerfile
CMD ["uvicorn", "app.main:app", "--proxy-headers", "--host", "0.0.0.0", "--port", "80"]
```
