# 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.

**Typer** é o irmão menor do FastAPI. E seu propósito é ser o **FastAPI das _CLIs_**. ⌨️ 🚀

## Requisitos

FastAPI está nos ombros de gigantes:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> para as partes web.

custom proprietary headers can be added <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">using the 'X-' prefix</a>.

But if you have custom headers that you want a client in a browser to be able to see, you need to add them to your CORS configurations ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}) using the parameter `expose_headers` documented in <a href="https://www.starlette.io/middleware/#corsmiddleware"...

   *
   * <p>A failing {@link TearDown} may or may not fail a tl4j test, depending on the version of
   * JUnit test case you are running under. To avoid failing in the face of an exception regardless
   * of JUnit version, implement a {@link SloppyTearDown} instead.
   *
   * <p>tl4j details: For backwards compatibility, {@code junit3.TearDownTestCase} currently does

 * Exception thrown when there is an issue with the suggest settings.
 * This exception extends {@link RuntimeException}, so it is an unchecked exception.
 *
 * <p>There are three constructors available for this exception:</p>

 *   <li>{@link #SuggestSettingsException(Throwable)}: Constructs a new exception with the specified cause.</li>
