使用新的Service实现,我是否必须为我的所有服务提供Options方法？

使用我的所有服务当前使用的旧ServiceBase方法,OPTIONS在没有Access-Control-Allow-Origin标头的情况下返回OK.

这是一个例子:

HelloService使用Service

GoodbyeService使用ServiceBase

刚刚升级到 v2，这不再有效；如果我尝试使用 Count()，我会收到类似的错误

public class Deck_Ratings : AbstractIndexCreationTask<DeckRating, Deck_Ratings.ReduceResult>
{
    public class ReduceResult
    {
        public string DeckId { get; set; }
        public int Rating { get; set; }
    }

    public Deck_Ratings()
    {
        Map = deckRatings => deckRatings.Select(deckRating => new 
                             { 
                                 deckRating.DeckId, 
                                 deckRating.Rating 
                             });
        Reduce = reduceResults => reduceResults
                                      .GroupBy(reduceResult => reduceResult.DeckId)
                                      .Select(grouping => new 
                                              {
                                                  DeckId = grouping.Key, 
                                                  Rating = grouping.Average(reduceResult => reduceResult.Rating)
                                               });
    }
}
