我之前也在思考拦截器的设计这块。 有cicada现在的拦截器有几点看法：

• 不合理的地方

  • 缺少拦截驳回的功能。
  • 不能设置拦截器的顺序。

• Support will be better

  • IncludeUrlPatterns
  • ExcludeUrlPatterns

我之前设计的接口是这样的：

public interface HttyInterceptorAdapter extends HttyInterceptorWrapper, Priority, UrlPatternMatchEnable {

    @Override
    default boolean preHandle(HttyRequest request, HttyResponse response) {
        return true;
    }

    @Override
    default void postHandle(HttyRequest request, HttyResponse response) {
    }

    @Override
    int getPriority();

    @Override
    Collection<String> getIncludeUrlPatterns();

    @Override
    Collection<String> getExcludeUrlPatterns();
}

能否用在cicada中，我提个pr？ 或者有其他想法？
