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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | 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> /// 资源类型 /// 资源数据 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | using SlideCaptcha.Exceptions;namespace SlideCaptcha.Model{ public class SliderImageCaptchaInfo : ImageCaptchaInfo { /// <summary> /// 凹槽x坐标 /// </summary> public int X { get; set; } /// <summary> /// 凹槽y坐标 /// </summary> public int Y { get; set; } /// <summary> /// 凹槽位置百分比 /// </summary> public float Percent { get { if (BackgroundImageWidth |
SlideTrack.cs
·SlideTrack.cs：滑动轨迹·
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 | using SlideCaptcha.Exceptions;using System;using System.Collections.Generic;namespace SlideCaptcha.Model{ /// <summary> /// 滑动轨迹 /// </summary> public class SlideTrack { /// <summary> /// 背景图片宽度(可能经过缩放，不是原始图片宽高) /// </summary> public int BackgroundImageWidth { get; set; } /// <summary> /// 背景图片高度(可能经过缩放，不是原始图片宽高) /// </summary> public int BackgroundImageHeight { get; set; } /// <summary> /// 滑块图片宽度(可能经过缩放，不是原始图片宽高) /// </summary> public int SliderImageWidth { get; set; } /// <summary> /// 滑块图片高度(可能经过缩放，不是原始图片宽高) /// </summary> public int SliderImageHeight { get; set; } /// <summary> /// 滑动开始时间(可能经过缩放，不是原始图片宽高) /// </summary> public DateTime StartTime { get; set; } /// <summary> /// 滑动结束时间 /// </summary> public DateTime EndTime { get; set; } /// <summary> /// 轨迹 /// </summary> public List<track> Tracks { get; set; } /// <summary> /// 滑动比例 /// </summary> public float Percent { get { if (this.BackgroundImageWidth |
TemplatePair.cs
·TemplatePair.cs：模板类·
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 | namespace SlideCaptcha.Model{ public class TemplatePair { public TemplatePair() { } /// <summary> /// 滑块资源 /// </summary> public Resource Slider { get; set; } /// <summary> /// 凹槽资源 /// </summary> public Resource Notch { get; set; } /// <summary> /// 模板类型 /// </summary> public string TYPE { get; set; } /// <summary> /// 构造函数 /// </summary> /// 滑块资源 /// 凹槽资源 /// 末班类型 public TemplatePair(Resource slider, Resource notch,string type) { Slider = slider; Notch = notch; TYPE = type; } /// <summary> /// 创建模板 /// </summary> /// 滑块资源 /// 凹槽资源 /// public static TemplatePair Create(Resource slider, Resource notch,string type) { return new TemplatePair(slider, notch,type); } }} |
Track.cs
Track.cs ：滑动数据实体类
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | namespace SlideCaptcha.Model{ public class Track { /// <summary> /// X轴 /// </summary> public int X { get; set; } /// <summary> /// Y轴 /// </summary> public int Y { get; set; } /// <summary> /// 时间 /// </summary> public int T { get; set; } }} |
代码中SlideCaptchaException是自定义错误类。自定义错误类在Extensions文件夹下，这个后面的代码会进行说明。
