项目基于 Hei.Captcha 为 Hei.Captcha 的依赖注入版本
示例
中文泡泡验证码
字母数字组合验证码
表单Demo
如何使用
添加包
Install-Package DUWENINK.Captcha
添加注入(在 StartUp.cs 文件的 public void ConfigureServices(IServiceCollection services) 方法中)
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
services.AddMemoryCache();//使用缓存
services.AddDUWENINKCaptcha();//使用验证码
}
在Controller中添加注入
/// <summary>
/// 依赖注入
/// </summary>
private SecurityCodeHelper _securityCode ;
private readonly IMemoryCache _cache;
public HomeController(SecurityCodeHelper securityCode, IMemoryCache cache)
{
_securityCode = securityCode;
_cache = cache;
}
#region 生成验证码
/// <summary>
/// 泡泡中文验证码

/// <returns></returns>
[HttpPost("BubbleCode")]
public IActionResult BubbleCode()
{
var code = _securityCode.GetRandomCnText(2);//生成的中文验证码
var vGuid = Guid.NewGuid().ToString();//guid
var imgbyte = _securityCode.GetBubbleCodeByte(code);//生成的中文图片
//相对于现在的过期时间 缓存相对于现在的时间后5分钟失效
_cache.Set(vGuid, code, new TimeSpan(0, 1, 0));
Response.Cookies.Append("validatecode", vGuid);//把生成的唯一Guid添加到cookie发送给前端
return File(imgbyte, "image/png");
}
/// <summary>

[HttpPost("HybridCode")]
public IActionResult HybridCode()
{
var code = _securityCode.GetRandomEnDigitalText(4);
var vGuid = Guid.NewGuid().ToString();//guid
var imgbyte = _securityCode.GetEnDigitalCodeByte(code);
//相对于现在的过期时间 缓存相对于现在的时间后5分钟失效
_cache.Set(vGuid, code, new TimeSpan(0, 1, 0));
Response.Cookies.Append("validatecode", vGuid);//把生成的唯一Guid添加到cookie发送给前端
return File(imgbyte, "image/png");
}

#region 验证验证码
/// <summary>

[HttpPost("VerifyCode")]
public NormalResult<bool> VerifyCode([FromBody]ValidatecodeDto filter)
{
_cache.TryGetValue(filter.ValidatecodeFromCookie, out string value);
return new NormalResult<bool> { Data = string.Equals(value, filter.TextByUser, StringComparison.OrdinalIgnoreCase) };

高级
参照Demo, 通过修改/丰富应用程序运行目录./fonts
目录下的字体文件,生成更多不同字体组合的验证码。
