## Установка пользовательских обработчиков исключений

Вы можете добавить пользовательские обработчики исключений с помощью <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">то же самое исключение - утилиты от Starlette</a>.

Допустим, у вас есть пользовательское исключение `UnicornException`, которое вы (или используемая вами библиотека) можете `вызвать`.

# Response - Cambiar Código de Estado

Probablemente leíste antes que puedes establecer un [Código de Estado de Response](../tutorial/response-status-code.md){.internal-link target=_blank} por defecto.

Pero en algunos casos necesitas devolver un código de estado diferente al predeterminado.

## Caso de uso

Por ejemplo, imagina que quieres devolver un código de estado HTTP de "OK" `200` por defecto.

		"Total number of messages that failed to send since start",
		targetID)
	auditTargetQueueLengthMD = NewGaugeMD(auditTargetQueueLength,
		"Number of unsent messages in queue for target",
		targetID)
	auditTotalMessagesMD = NewCounterMD(auditTotalMessages,
		"Total number of messages sent since start",
		targetID)
)

// loadAuditMetrics - `MetricsLoaderFn` for audit

  # and print the last word from each
  awk '/Streaming build results to/ {print $NF}' "$TFCI_OUTPUT_DIR/script.log" | uniq
}

# Print out any ResultStore URLs for Bazel invocations' results.
# Each failed target there will have its own representation, making failures
# easier to find and read.
function resultstore_extract {
  local PYTHON_BIN XML_PATH
  PYTHON_BIN=$(which python3 2>/dev/null || which python)

If you have an older version, you would get errors when trying to use `Annotated`.

Make sure you [Upgrade the FastAPI version](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} to at least 0.95.1 before using `Annotated`.

## Instalar manejadores de excepciones personalizados

Puedes agregar manejadores de excepciones personalizados con <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">las mismas utilidades de excepciones de Starlette</a>.

Supongamos que tienes una excepción personalizada `UnicornException` que tú (o un paquete que usas) podría lanzar.

## Instalando manipuladores de exceções customizados

Você pode adicionar manipuladores de exceção customizados com <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">a mesma seção de utilidade de exceções presentes no Starlette</a>

Digamos que você tenha uma exceção customizada `UnicornException` que você (ou uma biblioteca que você use) precise lançar (`raise`).

If you want to secure your API, there are several better things you can do, for example:

* Make sure you have well defined Pydantic models for your request bodies and responses.

## OpenAPI 및 API 문서

추가 상태 코드와 응답을 직접 반환하는 경우, FastAPI는 반환할 내용을 미리 알 수 있는 방법이 없기 때문에 OpenAPI 스키마(API 문서)에 포함되지 않습니다.

#
# this script cross-compiles a toolchain for that GOOS/GOARCH
# combination, leaving the resulting tree in ../../go-${GOOS}-${GOARCH}-bootstrap.
# That tree can be copied to a machine of the given target type
# and used as $GOROOT_BOOTSTRAP to bootstrap a local build.
#
# Only changes that have been committed to Git (at least locally,
# not necessary reviewed and submitted to master) are included in the tree.
