func_val

预定酒店的案例中的hotel_option函数没有在user_function_manager.cpp文件中进行注册？
func_val:hotel_option=service_http_get:hotel_service,/hotel/book?time={%time%}&hotel={%hotel%}&room_type={%room_type%}这个函数是调用的get请求，是不是就不需要在user_function_manager.cpp中注册？那“hotel_option”是需要在哪里配置？

Start in user_function_manager.cpp and trace references to hotel_option and service_http_get, using the hotel booking example in the issue as the reproduction context. Determine whether the GET-based function is registered there or configured elsewhere, and identify the relevant configuration location. Done means the registration or configuration path and expected behavior are clearly established.
