### Die Unteranwendung mounten { #mount-the-sub-application }

Mounten Sie in Ihrer Top-Level-Anwendung `app` die Unteranwendung `subapi`.

In diesem Fall wird sie im Pfad `/subapi` gemountet:

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[11, 19] *}

Nesse caso, você poderia querer documentar como essa API externa *deveria* ser. Que *operação de rota* ela deveria ter, que corpo ela deveria esperar, que resposta ela deveria retornar, etc.

## Um aplicativo com callbacks { #an-app-with-callbacks }

Vamos ver tudo isso com um exemplo.

Imagine que você desenvolve um aplicativo que permite criar faturas.

Essas faturas terão um `id`, `title` (opcional), `customer` e `total`.

	var err error
	tmpdir, err = os.MkdirTemp("", "go_ios_exec_")
	if err != nil {
		return 1, err
	}
	if !debug {
		defer os.RemoveAll(tmpdir)
	}

	appdir := filepath.Join(tmpdir, "gotest.app")
	os.RemoveAll(appdir)

	if err := assembleApp(appdir, os.Args[1]); err != nil {
		return 1, err
	}

	// This wrapper uses complicated machinery to run iOS binaries. It

Und Sie möchten diese Exception global mit FastAPI handhaben.

Sie könnten einen benutzerdefinierten Exceptionhandler mit `@app.exception_handler()` hinzufügen:

{* ../../docs_src/handling_errors/tutorial003_py39.py hl[5:7,13:18,24] *}

Hier, wenn Sie `/unicorns/yolo` anfordern, wird die *Pfadoperation* eine `UnicornException` `raise`n.
