Wir können denselben Ansatz auch verwenden, um in einem Exceptionhandler auf den Requestbody zuzugreifen.

Alles, was wir tun müssen, ist, den Request innerhalb eines `try`/`except`-Blocks zu handhaben:

```Python hl_lines="13  15"
{!../../docs_src/custom_request_and_route/tutorial002.py!}
```

Este parâmetro recebe um `dict`, as chaves são os códigos de status para cada retorno, como por exemplo `200`, e os valores são um outro `dict` com a informação de cada um deles.

Cada um desses `dict` de retorno pode ter uma chave `model`, contendo um modelo do Pydantic, assim como o `response_model`.

O **FastAPI** pegará este modelo, gerará o esquema JSON dele e incluirá no local correto do OpenAPI.

        leftoverFiles.forEach {
            assertTrue(projectDir.resolve(it).walk().filter { it.isFile }.toList().isEmpty())
        }
    }

    @Test
    fun `fail build if leftover file found and test passes`() {
        val result = run(":successful-test-with-leftover:test", "--no-watch-fs").buildAndFail()
        assertEquals(TaskOutcome.SUCCESS, result.task(":successful-test-with-leftover:test")!!.outcome)

  /*
   * J2CL's EnumMap does not need the Class instance, so we can use Object.class instead. (Or we
   * could use null, but that messes with our nullness checking, including under J2KT. We could
   * probably work around it by changing how we annotate the J2CL EnumMap, but that's probably more
   * trouble than just using Object.class.)

   *       CacheLoader#loadAll bulk loading implementations}
   * </ul>
   *
   * <p><b>Warning:</b> For any given key, every {@code loader} used with it should compute the same
   * value. Otherwise, a call that passes one {@code loader} may return the result of another call
   * with a differently behaving {@code loader}. For example, a call that requests a short timeout

Sie übergeben es einfach an `Depends` und **FastAPI** weiß, wie der Rest erledigt wird.

## `Annotated`-Abhängigkeiten wiederverwenden

In den Beispielen oben sehen Sie, dass es ein kleines bisschen **Codeverdoppelung** gibt.

* Modelo de documentação automática com <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (já que o OpenAPI em si é baseado no JSON Schema).
* Projetado em cima desses padrões após um estudo meticuloso, em vez de uma reflexão breve.
* Isso também permite o uso de **geração de código do cliente** automaticamente em muitas linguagens.

### Documentação automática
