...that's because the client generator uses the OpenAPI internal **operation ID** for each *path operation*.

OpenAPI requires that each operation ID is unique across all the *path operations*, so FastAPI uses the **function name**, the **path**, and the **HTTP method/operation** to generate that operation ID, because that way it can make sure that the operation IDs are unique.

# Body - Множество параметров

Теперь, когда мы увидели, как использовать `Path` и `Query` параметры, давайте рассмотрим более продвинутые примеры обьявления тела запроса.

## Обьединение `Path`, `Query` и параметров тела запроса

Во-первых, конечно, вы можете объединять параметры `Path`, `Query` и объявления тела запроса в своих функциях обработки, **FastAPI** автоматически определит, что с ними нужно делать.

public class DfsReferralRequestBuffer implements Encodable {

    private final int maxReferralLevel;
    private final String path;


    /**
     * @param filename
     * @param maxReferralLevel
     */
    public DfsReferralRequestBuffer ( String filename, int maxReferralLevel ) {
        this.path = filename;
        this.maxReferralLevel = maxReferralLevel;
    }
