## Резюме

С помощью `Query`, `Path` (и других классов, которые мы пока не затронули) вы можете добавлять метаданные и строковую валидацию тем же способом, как и в главе [Query-параметры и валидация строк](query-params-str-validations.md){.internal-link target=_blank}.

А также вы можете добавить валидацию числовых данных:

):
    await websocket.accept()
    while True:
        data = await websocket.receive_text()
        await websocket.send_text(
            f"Session cookie or query token value is: {cookie_or_token}"
        )
        if q is not None:
            await websocket.send_text(f"Query parameter q is: {q}")

):
    await websocket.accept()
    while True:
        data = await websocket.receive_text()
        await websocket.send_text(
            f"Session cookie or query token value is: {cookie_or_token}"
        )
        if q is not None:
            await websocket.send_text(f"Query parameter q is: {q}")
