Lets start the lambda handler.

## Start MinIO with Lambda target

## Caso de Uso { #use-case }

Empecemos con un ejemplo de **caso de uso** y luego veamos cómo resolverlo con esto.

Imaginemos que tienes algunos **modelos de machine learning** que quieres usar para manejar requests. 🤖

如果你引发任何异常，它将传递给使用 `yield` 的依赖项，包括 `HTTPException`。在大多数情况下你应当从使用 `yield` 的依赖项中重新抛出捕获的异常或者一个新的异常来确保它会被正确的处理。

## 包含 `yield`, `HTTPException`, `except` 的依赖项和后台任务

/// warning | 注意

你大概率不需要了解这些技术细节，可以跳过这一章节继续阅读后续的内容。

如果你使用的FastAPI的版本早于0.106.0，并且在使用后台任务中使用了包含 `yield` 的依赖项中的资源，那么这些细节会对你有一些用处。

### 包含 `yield` 和 `except` 的依赖项的技术细节

O mesmo exemplo de antes, retornando uma `HTMLResponse`, poderia parecer com:

{* ../../docs_src/custom_response/tutorial003_py39.py hl[2,7,19] *}

/// warning | Atenção

Uma `Response` retornada diretamente em sua *função de operação de rota* não será documentada no OpenAPI (por exemplo, o `Content-Type` não será documentado) e não será visível na documentação interativa automática.

The same example from above, returning an `HTMLResponse`, could look like:

{* ../../docs_src/custom_response/tutorial003_py39.py hl[2,7,19] *}

/// warning

A `Response` returned directly by your *path operation function* won't be documented in OpenAPI (for example, the `Content-Type` won't be documented) and won't be visible in the automatic interactive docs.

Das gleiche Beispiel von oben, das eine `HTMLResponse` zurückgibt, könnte so aussehen:
