// 1.定义接口
type IShows interface {
	GetShows(ctx context.Context) (shows []entity.GoShows, err error)
	GetVideos(ctx context.Context) (videos []entity.GoShows, err error)
	AddShow(ctx context.Context, show do.GoShows) (err error)
	EditShow(ctx context.Context, show do.GoShows) (err error)
	DeleteShow(ctx context.Context) (err error) //id通过路径中获取
}

// 2.定义接口变量
var localShow IShows

// 3.定义获取接口实例的函数
func GetShows() IShows {
	if localShow == nil {
		panic("IShows未实现或未注册")
	}
	return localShow
}

// 4.定义一个接口实现的注册方法
func RegisterShows(show IShows) {
	localShow = show
}
