## Benutzerdefinierte `APIRoute`-Klasse in einem Router

Sie können auch den Parameter `route_class` eines `APIRouter` festlegen:

   * Inserts the specified element into this priority queue. As the queue is unbounded this method
   * will never block.

   * @param e the element to add
   * @param timeout This parameter is ignored as the method never blocks
   * @param unit This parameter is ignored as the method never blocks
   * @return {@code true}
   * @throws ClassCastException if the specified element cannot be compared with elements currently

Якщо Ви оголосите його як є, то, оскільки це одиничне значення,  **FastAPI**  припускатиме, що це параметр запиту (query parameter).

Але Ви можете вказати **FastAPI** обробляти його як інший ключ тіла (body key), використовуючи `Body`:
