ValidateResult.cs

在项目根目录下，创建ValidateResult.cs。其功能是提供验证后返回的信息

namespace SlideCaptcha
{
    public class ValidateResult
    {
        public ValidateResultType Result { get; set; }
        public string Message { get; set; }

        public static ValidateResult Success()
        {
            return new ValidateResult { Result = ValidateResultType.Success, Message = "成功" };
        }

        public static ValidateResult Fail()
        {
            return new ValidateResult { Result = ValidateResultType.ValidateFail, Message = "验证失败" };
        }

        public static ValidateResult Timeout()
        {
            return new ValidateResult { Result = ValidateResultType.Timeout, Message = "验证超时" };
        }

        public enum ValidateResultType
        {
            Success = 0,
            ValidateFail = 1,
            Timeout = 2
        }
    }
}

ICaptcha.cs

在Interface文件夹下，建一个ICaptcha.cs，用于生成验证码和进行校验。

using SlideCaptcha.Model;
using System.Threading.Tasks;

namespace SlideCaptcha.Interface
{
    public interface ICaptcha
    {
        /// <summary>
        /// 生成验证码
        /// </summary>
        /// <param name="captchaId">验证码id</param>
        /// <returns></returns>
        Task<CaptchaData> GenerateCaptchaImageAsync(string type, string captchaId = null);

        /// <summary>
        /// 校验
        /// </summary>
        /// <param name="captchaId">验证码id</param>
        /// <param name="slideTrack">滑动轨迹</param>
        /// <returns></returns>
        ValidateResult Validate(string captchaId, SlideTrack slideTrack);
    }
}

        /// 判断传入的资源类型是否存在
        /// </summary>
        /// <param name="handlerType"></param>
        /// <returns></returns>
        bool CanHandle(string handlerType);

        /// <summary>
        /// 生成资源
        /// </summary>
        /// <param name="resource"></param>
        /// <returns></returns>
        Task<byte[]> Handle(Resource resource);
    }

    public interface IResourceHandlerManager
    {
        /// <summary>
        /// 根据资源，生成所需要的byte[]
        /// </summary>
        /// <param name="resource"></param>
        /// <returns></returns>
        Task<byte[]> Handle(Resource resource);
