Eine „Middleware“ ist eine Funktion, die mit jedem **Request** arbeitet, bevor er von einer bestimmten *Pfadoperation* verarbeitet wird. Und auch mit jeder **Response**, bevor sie zurückgegeben wird.

* Sie nimmt jeden **Request** entgegen, der an Ihre Anwendung gesendet wird.
* Sie kann dann etwas mit diesem **Request** tun oder beliebigen Code ausführen.

{
    HINSTANCE instance = GetModuleHandle("hello");
    WCHAR * pBuf = NULL;
    int len = LoadStringW(instance, stringID, reinterpret_cast<LPWSTR>(&pBuf), 0);
    std::wstring wide = std::wstring(pBuf, len);
    return std::string(wide.begin(), wide.end());
}

void hello() {
    std::string hello = LoadStringFromResource(IDS_HELLO);
    std::cout << hello << std::endl;

    TimeoutFuture<V> result = new TimeoutFuture<>(delegate);
    Fire<V> fire = new Fire<>(result);
    result.timer = scheduledExecutor.schedule(fire, time, unit);
    delegate.addListener(fire, directExecutor());
    return result;
  }

  /*
   * Memory visibility of these fields. There are two cases to consider.
   *
   * 1. visibility of the writes to these fields to Fire.run:

    }
}
```

!!! note "Hinweis"
    Beachten Sie, dass, obwohl `item` wie zuvor deklariert wurde, es nun unter einem Schlüssel `item` im Body erwartet wird.

**FastAPI** wird die automatische Konvertierung des Requests übernehmen, sodass der Parameter `item` seinen spezifischen Inhalt bekommt, genau so wie der Parameter `user`.

            String formattedLeft = CollectionUtils.join("\n", keptAccessors.keySet());
            throw new RuntimeException("The following accessors were upgraded, but didn't match any removed/changed method:\n\n" + formattedLeft);
        }

        // Find accessors that were removed but shouldn't be
        Map<AccessorKey, ReplacedAccessor> removedAccessors = new HashMap<>(oldAccessorsOfUpgradedProperties);
