  1 | # LazySlideCaptcha （基于SkiaSharp）
  2 | 
  3 | #### 介绍
  4 | LazySlideCaptcha是基于.Net Standard 2.1的滑动验证码模块。项目同时提供一个基于vue2的演示[前端组件](https://gitee.com/pojianbing/lazy-slide-captcha/tree/master/Components/vue2)和[背景图裁剪工具](http://www.sunseeyou.com/cropper/index.html)。从2.0.0起绘图模块由ImageSharp调整为SkiaSharp。
  5 | **[【码云地址】](https://gitee.com/pojianbing/lazy-slide-captcha)|[【Github地址】](https://github.com/pojianbing/LazySlideCaptcha)**

 10 | 
 11 | [![输入图片说明](Images/show.gif)    ](http://www.sunseeyou.com/)
 12 | 
 13 | 
 14 | #### 快速开始
 15 | 
 16 | 1. 安装
 17 | - [Package Manager](https://www.nuget.org/packages/Lazy.SlideCaptcha.Core)
 18 | 
 19 | ```powershell
 20 | Install-Package Lazy.SlideCaptcha.Core
 21 | ```
 22 | 
 23 | - [.NET CLI](https://www.nuget.org/packages/Lazy.SlideCaptcha.Core)
 24 | 
 25 | ```powershell
 26 | dotnet add package Lazy.SlideCaptcha.Core
 27 | ```
 28 | 
 29 | 2. 注册并配置服务
 30 | ``` c#
 31 | builder.Services.AddDistributedMemoryCache();
 32 | builder.Services.AddSlideCaptcha(builder.Configuration);
 33 | 
 34 | // 如果使用redis分布式缓存
 35 | //builder.Services.AddStackExchangeRedisCache(options =>
 36 | //{
 37 | //    options.Configuration = builder.Configuration.GetConnectionString("RedisCache");
 38 | //    options.InstanceName = "captcha:";
 39 | //});
 40 | ```
 41 | ``` json
 42 | "SlideCaptcha": {
 43 |     "Backgrounds": [
 44 |       {
 45 |         "Type": "file",
 46 |         "Data": "wwwroot/images/background/1.jpg"
 47 |       },
 48 |       {
 49 |         "Type": "file",
 50 |         "Data": "wwwroot/images/background/2.jpg"
 51 |       }
 52 |     ]
 53 |   }
 54 | ```
 55 | > 背景图片要求尺寸要求为 **_552 X 344_** , 快速开始可在 **_Demo_**  项目  **_wwwroot/images/background_**  下挑选。（仅用作演示，生产请自行制作。）也可以通过[裁剪工具](http://www.sunseeyou.com/cropper/index.html)制作，非常简单，上传图片，拖动范围后保存自动生成 _**552 X 344**_ 图片。
 56 | 
 57 | 3. 接口定义
 58 | ``` c#
 59 | [Route("api/[controller]")]
 60 | [ApiController]
 61 | public class CaptchaController : ControllerBase
 62 | {
 63 |     private readonly ICaptcha _captcha;
 64 | 
 65 |     public CaptchaController(ICaptcha captcha)
 66 |     {
 67 |         _captcha = captcha;
 68 |     }
 69 | 
 70 |     /// <summary>
 71 |     /// id
 72 |     /// </summary>
 73 |     /// <param name="id"></param>
 74 |     /// <returns></returns>
 75 |     [Route("gen")]
 76 |     [HttpGet]
 77 |     public CaptchaData Generate()
 78 |     {
 79 |         return _captcha.Generate();
 80 |     }
 81 | 
 82 |     /// <summary>
 83 |     /// id
 84 |     /// </summary>
 85 |     /// <param name="id"></param>
 86 |     /// <returns></returns>
 87 |     [Route("check")]
 88 |     [HttpPost]
 89 |     public ValidateResult Validate([FromQuery]string id, SlideTrack track)
 90 |     {
 91 |         return _captcha.Validate(id, track);
 92 |     }
 93 | }
 94 | 
 95 | ```
 96 | 至此后端Api服务已搭建完成。
 97 | 
 98 | 4. 前端  
 99 | 前端提供演示组件[lazy-slide-captcha](https://gitee.com/pojianbing/lazy-slide-captcha/tree/master/Components/vue2)，可通过npm安装。Demo项目为了演示方便直接采用script直接引入方式。

199 |     </script>
200 | }
201 | ```
202 | 
203 | #### 配置说明
204 | 支持配置文件和代码配置，同时配置则代码配置覆盖配置文件。
205 | - 配置文件
206 | ``` c#
207 | "SlideCaptcha": {
208 |     "ExpirySeconds": 60, // 缓存过期时长
209 |     "StoreageKeyPrefix": "", // 缓存前缀
210 |     "Tolerant": 0.02, // 容错值(校验时用，缺口位置与实际滑动位置匹配容错范围)
211 |     "Backgrounds": [ // 背景图配置
212 |       {
213 |         "Type": "file",
214 |         "Data": "wwwroot/images/background/1.jpg"
215 |       }
216 |     ],
217 |     // Templates不配置，则使用默认模板
218 |     "Templates": [
219 |       {
220 |         "Slider": {
221 |           "Type": "file",
222 |           "Data": "wwwroot/images/template/1/slider.png"
223 |         },
224 |         "Hole": {
225 |           "Type": "file",
226 |           "Data": "wwwroot/images/template/1/hole.png"
227 |         }
228 |       }
229 |     ]
230 |   }
231 | ```
232 | 
233 | - 代码配置
234 | ``` c#
235 | builder.Services.AddSlideCaptcha(builder.Configuration, options =>
236 | {
237 |     options.Tolerant = 0.02f;
238 |     options.StoreageKeyPrefix = "slider-captcha";
239 | 
240 |     options.Backgrounds.Add(new Resource(FileResourceHandler.TYPE, @"wwwroot/images/background/1.jpg"));
241 |     options.Templates.Add
242 |     (
243 |         TemplatePair.Create
244 |         (
245 |             new Resource(FileResourceHandler.TYPE, @"wwwroot/images/template/1/slider.png"),
246 |             new Resource(FileResourceHandler.TYPE, @"wwwroot/images/template/1/hole.png")
247 |         )
248 |     );
249 | });
250 | ```
251 | #### 扩展
252 | 1. Template自定义  
253 |  _**Template**_ 是指用于生成凹槽和拖块的图片，可通过Templates配置节点设置设置自定义Template。 默认五个 _**Template**_ （不要配置，已经包含在类库内部）如下：
254 | 
255 | |  slider                                            |  hole                                           |  slider                                            |  hole                                           |
256 | |----------------------------------------------------|-------------------------------------------------|----------------------------------------------------|-------------------------------------------------|
257 | | ![](Lazy.SlideCaptcha.Core/templates/1/slider.png) | ![](Lazy.SlideCaptcha.Core/templates/1/hole.png)| ![](Lazy.SlideCaptcha.Core/templates/2/slider.png) | ![](Lazy.SlideCaptcha.Core/templates/2/hole.png)|
258 | | ![](Lazy.SlideCaptcha.Core/templates/3/slider.png) | ![](Lazy.SlideCaptcha.Core/templates/3/hole.png)| ![](Lazy.SlideCaptcha.Core/templates/4/slider.png) | ![](Lazy.SlideCaptcha.Core/templates/4/hole.png)|
259 | | ![](Lazy.SlideCaptcha.Core/templates/5/slider.png) | ![](Lazy.SlideCaptcha.Core/templates/5/hole.png)|
260 | 
261 | 禁用默认 _**Template**_调用DisableDefaultTemplates即可:
262 | ``` c#
263 | builder.Services.AddSlideCaptcha(builder.Configuration)
264 |     .DisableDefaultTemplates();
265 | ```
266 | 
267 | 2. Validator自定义
268 | 类库提供 _**SimpleValidator**_ ， _**BasicValidator**_ 两个实现。  
269 |  _**SimpleValidator**_ 仅位置验证，_**BasicValidator**_除位置验证外，同时对轨迹做验证。_**BasicValidator**由于算法的原因，容易误判，因此类库默认用_**SimpleValidator**_ 做为默认 _**Validator**_ 。  
270 | 自定义 _**Validator**_ 继承 **_BaseValidator_** ， _**BaseValidator**_ 提供了基本的位置验证。   
271 | 
272 | 举一个栗子：
273 | ``` c# 
274 | public class CustomValidator: BaseValidator
275 | {
276 |     public override bool ValidateCore(SlideTrack slideTrack, CaptchaValidateData captchaValidateData)
277 |     {
278 |         // BaseValidator已做了基本滑块与凹槽的对齐验证，这里做其他验证
279 | 
280 |         return true;
281 |     }
282 | }
283 | ```
284 | 
285 | 替换默认的Validator
286 | ``` c#
287 | builder.Services.AddSlideCaptcha(builder.Configuration);
288 |     .ReplaceValidator<CustomValidator>();
289 | ```
290 | 
291 | 3. ResourceProvider自定义  
292 | 除了通过Options配置Background和Template外，你也可以通过自定义ResourceProvider的形式提供Background和Template。
293 | ```csharp
294 | public class CustomResourceProvider : IResourceProvider
295 | {
296 |     public List<Resource> Backgrounds()
297 |     {
298 |         return Enumerable.Range(1, 10)
299 |             .ToList()
300 |             .Select(e => new Resource(Core.Resources.Handler.FileResourceHandler.TYPE, $"wwwroot/images/background/{e}.jpg"))
301 |             .ToList();
302 |     }
303 |     
304 |     // 这里返回自定义的Template
305 |     public List<TemplatePair> Templates()
306 |     {
307 |         return new List<TemplatePair>();
308 |     }
309 | }
310 | ```
311 | 
312 | 注册ResourceProvider
313 | ``` csharp
314 | builder.Services.AddSlideCaptcha(builder.Configuration)
315 |     .AddResourceProvider<CustomResourceProvider>();
316 | ```
317 | 
318 | 4. 自定义ResourceHandler
319 | ```csharp
320 | public class UrlResourceHandler : IResourceHandler
321 | {
322 |     public const string Type = "url";
323 | 
324 |     public bool CanHandle(string handlerType)
325 |     {
326 |         return handlerType == Type;
327 |     }
328 | 
329 |     /// <summary>
330 |     /// 这里仅演示，仍然从本地读取。实际需要通过Http读取
331 |     /// </summary>
332 |     /// <param name="resource"></param>
333 |     /// <returns></returns>
334 |     /// <exception cref="ArgumentNullException"></exception>
335 |     public byte[] Handle(Resource resource)
336 |     {
337 |         if (resource == null) throw new ArgumentNullException(nameof(resource));
338 |         return File.ReadAllBytes(resource.Data);
339 |     }
340 | }
341 | ```
342 | 
343 | 注册ResourceHandler
344 | ```csharp
345 | builder.Services.AddSlideCaptcha(builder.Configuration)
346 |     .AddResourceHandler<UrlResourceHandler>();
347 | ```
348 |
