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 
        /// </summary>
        /// <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>
        /// 数字字母组合验证码
        /// </summary>
        /// <returns></returns>
        [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");
        }

        #endregion

        #region 验证验证码
        /// <summary>
        /// 验证码验证
        /// </summary>
        /// <returns></returns>
        [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) };
        }
