/**
 * Path validation utility to prevent directory traversal and other path-based attacks.

 * - Directory traversal prevention
 * - Path normalization
 * - Blacklist/whitelist support
 * - UNC path validation
 * - Special character filtering
 * - Length validation

Aber diese wird von `unicorn_exception_handler` gehandhabt.

Sie erhalten also einen sauberen Fehler mit einem HTTP-Statuscode von `418` und dem JSON-Inhalt:

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

/// note | Technische Details

Sie könnten auch `from starlette.requests import Request` und `from starlette.responses import JSONResponse` verwenden.

        /* Samba has a tendency to return referral paths and pathConsumed values
         * in such a way that there can be a slash at the end of the path. This
         * causes problems matching keys in resolve() where an extra slash causes
         * a mismatch. This strips trailing slashes from all keys to eliminate
         * this problem.

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`.

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`.
