### Überschreiben des `HTTPException`-Fehlerhandlers { #override-the-httpexception-error-handler }

Auf die gleiche Weise können Sie den `HTTPException`-Handler überschreiben.

Zum Beispiel könnten Sie eine Klartext-Response statt JSON für diese Fehler zurückgeben wollen:

    Note over dep: Ejecutar código hasta yield
    opt raise Exception

    opt raise
        operation -->> dep: Lanzar Exception (por ejemplo, HTTPException)
        opt handle

Bu durumda `startup` event handler fonksiyonu, "database" öğesini (sadece bir `dict`) bazı değerlerle başlatır.

Birden fazla event handler fonksiyonu ekleyebilirsiniz.

Ve tüm `startup` event handler’ları tamamlanmadan uygulamanız request almaya başlamaz.
