Wenn Sie einen Proxy zur Verarbeitung von HTTPS verwenden, weiß Ihr **Anwendungsserver** (z. B. Uvicorn über das FastAPI CLI) nichts über den HTTPS-Prozess, er kommuniziert per einfachem HTTP mit dem **TLS-Terminierungsproxy**.

In limited situations OkHttp will retry a route if connecting fails:

 * When making an HTTPS connection through an HTTP proxy, the proxy may issue an authentication challenge. OkHttp will call the proxy [authenticator](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-authenticator/) and try again.

# 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.

  private static <T> void testToString(
      Class<T> interfaceType, Function<? super T, ? extends T> wrapperFunction) {
    T proxy = new FreshValueGenerator().newFreshProxy(interfaceType);
    assertEquals(
        "toString() isn't properly forwarded",
        proxy.toString(),
        wrapperFunction.apply(proxy).toString());
  }

  private static @Nullable Object[] getParameterValues(Method method) {

   * can't coalesce connections that use a proxy, since proxies don't tell us the origin server's IP
   * address.
   */
  private fun routeMatchesAny(candidates: List<Route>): Boolean =
    candidates.any {
      it.proxy.type() == Proxy.Type.DIRECT &&
        route.proxy.type() == Proxy.Type.DIRECT &&
        route.socketAddress == it.socketAddress
    }

# Including WSGI - Flask, Django, others { #including-wsgi-flask-django-others }

You can mount WSGI applications as you saw with [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank}, [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank}.

For that, you can use the `WSGIMiddleware` and use it to wrap your WSGI application, for example, Flask, Django, etc.
