Verás ejemplos de esto en los próximos capítulos, sobre bases de datos relacionales y NoSQL, seguridad, etc.

## Compatibilidad de **FastAPI**

La simplicidad del sistema de inyección de dependencias hace que **FastAPI** sea compatible con:

* todas las bases de datos relacionales
* bases de datos NoSQL
* paquetes externos
* APIs externas
* sistemas de autenticación y autorización

        List<KerberosAuthData> authorizations = new ArrayList<>();

        switch (authType) {
        case KerberosConstants.AUTH_DATA_RELEVANT:
            authorizations = new KerberosRelevantAuthData(token, keys).getAuthorizations();
            break;
        case KerberosConstants.AUTH_DATA_PAC:

            break;
        default:

```
/files/{file_path:path}
```

In this case, the name of the parameter is `file_path`, and the last part, `:path`, tells it that the parameter should match any *path*.

So, you can use it with:

{* ../../docs_src/path_params/tutorial004.py hl[6] *}

/// tip

You might need the parameter to contain `/home/johndoe/myfile.txt`, with a leading slash (`/`).
