Es gibt einige Fälle, in denen Sie das generierte OpenAPI-Schema ändern müssen.

In diesem Abschnitt erfahren Sie, wie.

## Der normale Vorgang { #the-normal-process }

Der normale (Standard-)Prozess ist wie folgt.

Eine `FastAPI`-Anwendung (Instanz) verfügt über eine `.openapi()`-Methode, von der erwartet wird, dass sie das OpenAPI-Schema zurückgibt.

          routeDatabase = routeDatabase,
          call = call,
          fastFallback = fastFallback,
        )
      routeSelector = newRouteSelector
    }

    // List available IP addresses for the current proxy. This may block in Dns.lookup().
    if (!newRouteSelector.hasNext()) throw IOException("exhausted all routes")
    val newRouteSelection = newRouteSelector.next()
