.NET 6 实现滑动验证码（二）、基本数据
上一节，介绍了滑动验证码的基本情况，也创建了一个.NET 6的工程。本节内容是创建一些基础类。目录
[*]CaptchaData.cs
[*]CaptchaValidateData.cs
[*]ImageCaptchaInfo.cs
[*]Resource.cs
[*]SliderImageCaptchaInfo.cs
[*]SlideTrack.cs
[*]TemplatePair.cs
[*]Track.cs
本节创建的类全部在工程的Model目录下：
CaptchaData.cs
CaptchaData.cs：验证码的数据类实体
namespace SlideCaptcha.Model
{
public class CaptchaData
{
/// <summary>
/// id
/// </summary>
public string Id { get; set; }
/// <summary>
/// 背景图(含凹槽)
/// </summary>
public string BackgroundImage { get; set; }
/// <summary>
/// 滑动块图
/// </summary>
public string SliderImage { get; set; }
public CaptchaData(string id, string backgroundImage, string sliderImage)
{
Id = id;
BackgroundImage = backgroundImage;
SliderImage = sliderImage;
}
}
}id表示验证码的id值，用于校验验证码，BackgroundImage 是验证码图片base64，包含了凹槽。凹槽模板在templates目录下。SliderImage 是滑块图片。模板在templates下。
CaptchaValidateData.cs
CaptchaValidateData.cs：验证码验证数据实体
namespace SlideCaptcha.Model
{
public class CaptchaValidateData
{
/// <summary>
/// 滑动比例
/// </summary>
public float Percent { get; set; }
/// <summary>
/// 容错值(校验时用，缺口位置与实际滑动位置匹配容错范围)
/// </summary>
public float Tolerant { get; set; }
public CaptchaValidateData(float percent, float tolerant)
{
Percent = percent;
Tolerant = tolerant;
}
}
}ImageCaptchaInfo.cs
ImageCaptchaInfo.cs：证码图片信息实体
namespace SlideCaptcha.Model
{
public class ImageCaptchaInfo
{
/// <summary>
/// 背景图宽
/// </summary>
public int BackgroundImageWidth { get; set; }
/// <summary>
/// 背景图高
/// </summary>
public int BackgroundImageHeight { get; set; }
/// <summary>
/// 背景图
/// </summary>
public string BackgroundImageBase64 { get; set; }
/// <summary>
/// 滑动块图宽
/// </summary>
public int SliderImageWidth { get; set; }
/// <summary>
/// 滑动块图高
/// </summary>
public int SliderImageHeight { get; set; }
/// <summary>
/// 滑动块图
/// </summary>
public string SliderImageBase64 { get; set; }
}
}验证码实体类的基类，滑动验证码、旋转验证码、点选验证码、拼接验证码都基于这个类。
Resource.cs
Resource.cs ：资源实体类
namespace SlideCaptcha.Model
{
public class Resource
{
public Resource(){}
/// <summary>
/// 资源数据
/// </summary>
public string Data { get; set; }
/// <summary>
/// 资源类型
/// </summary>
public string Type { get; set; }
/// <summary>
/// 构造函数
/// </summary>
/// <param name="type">资源类型</param>
/// <param name="data">资源数据</param>
public Resource(string type,string data)
{
Type = type;
Data = data;
}
}
}资源数据，Data为要生成验证码图片路径。Type为类型，目前仅为本地文件，后期将扩展URL模式。
SliderImageCaptchaInfo.cs
SliderImageCaptchaInfo.cs：滑动验证码实体类
using SlideCaptcha.Exceptions;namespace SlideCaptcha.Model{ public class SliderImageCaptchaInfo : ImageCaptchaInfo { /// /// 凹槽x坐标 /// public int X { get; set; } /// /// 凹槽y坐标 /// public int Y { get; set; } /// /// 凹槽位置百分比 /// public float Percent { get { if (BackgroundImageWidth
