**FastAPI** позволяет определять дополнительную информацию и выполнять валидацию для ваших параметров.

Рассмотрим это приложение в качестве примера:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

Query-параметр `q` имеет тип `str | None`, это означает, что он имеет тип `str`, но также может быть `None`. Значение по умолчанию действительно `None`, поэтому FastAPI будет знать, что он не обязателен.

In diesen Fällen können Sie den `jsonable_encoder` verwenden, um Ihre Daten zu konvertieren, bevor Sie sie an eine Response übergeben:

{* ../../docs_src/response_directly/tutorial001_py310.py hl[5:6,20:21] *}

/// note | Technische Details

Sie könnten auch `from starlette.responses import JSONResponse` verwenden.

Para esos casos, puedes usar el `jsonable_encoder` para convertir tus datos antes de pasarlos a un response:

{* ../../docs_src/response_directly/tutorial001_py310.py hl[5:6,20:21] *}

/// note | Detalles técnicos

También podrías usar `from starlette.responses import JSONResponse`.
