Essa exceção será manipulada, contudo, pelo `unicorn_exception_handler`.

Dessa forma você receberá um erro "limpo", com o HTTP status code `418` e um JSON com o conteúdo:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | Detalhes Técnicos

Você também pode usar `from starlette.requests import Request` e `from starlette.responses import JSONResponse`.

{* ../../docs_src/path_params/tutorial005_py39.py hl[18,21,23] *}

In your client you will get a JSON response like:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Path parameters containing paths { #path-parameters-containing-paths }

Let's say you have a *path operation* with a path `/files/{file_path}`.

Pero será manejado por el `unicorn_exception_handler`.

Así que recibirás un error limpio, con un código de estado HTTP de `418` y un contenido JSON de:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | Nota Técnica

También podrías usar `from starlette.requests import Request` y `from starlette.responses import JSONResponse`.

{* ../../docs_src/path_params/tutorial005_py39.py hl[18,21,23] *}

En tu cliente recibirás un response JSON como:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Parámetros de path conteniendo paths { #path-parameters-containing-paths }

Imaginemos que tienes una *path operation* con un path `/files/{file_path}`.

{* ../../docs_src/path_params/tutorial005_py39.py hl[18,21,23] *}

In Ihrem Client erhalten Sie eine JSON-Response, wie etwa:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Pfad-Parameter, die Pfade enthalten { #path-parameters-containing-paths }

Angenommen, Sie haben eine *Pfadoperation* mit einem Pfad `/files/{file_path}`.

{* ../../docs_src/background_tasks/tutorial001.py hl[14] *}

`.add_task()` は以下の引数を受け取ります:

* バックグラウンドで実行されるタスク関数 (`write_notification`)。
* タスク関数に順番に渡す必要のある引数の列 (`email`)。
* タスク関数に渡す必要のあるキーワード引数 (`message="some notification"`)。

## 依存性注入

`BackgroundTasks` の使用は依存性注入システムでも機能し、様々な階層 (*path operations 関数*、依存性 (依存可能性)、サブ依存性など) で `BackgroundTasks` 型のパラメーターを宣言できます。
