Abp.Captcha
ABP 验证码模块
1. 介绍
Light.Abp.Captcha 库定义了验证码的发送、校验、存储等基本接口，并提供默认实现。（发送接口需集成后自行实现）验证码默认存储为缓存。
2. 如何使用?
2.1 安装
开发人员可以通过 NuGet 搜索 Light.Abp.Captcha 安装组件
2.2 配置
支持在设置中配置验证码过期时间
配置示例:
"Settings": {
"AbpCaptchas:EmailCaptcha.ExpireSeconds": 600,//邮箱验证码过期时间
"AbpCaptchas:SmsCaptcha.ExpireSeconds": 300,//短信验证码过期时间
"AbpCaptchas:Captcha.FrequencyLimitSeconds": 60//请求频率限制
},2.3 实现发送接口
需要在项目中实现验证码发送（短信或邮件）的接口
public class AliyunSmsCaptchaSender: ISmsCaptchaSender
{
public virtual Task<bool> SendAsync(Captcha captcha)
{
var templateCode = "";
var signName = "";
switch (captcha.Type)
{
case "login":
templateCode = "SMS_123456";
break;
case "retrievePassword":
case "changePassword":
templateCode = "SMS_1234567";
break;
}
var code = captcha.Code;
var smsRequest = new SendSmsRequest()
{
PhoneNumbers = captcha.Receiver,
TemplateCode = templateCode,
TemplateParam = JsonConvert.SerializeObject(new { code }),
SignName = signName,
};
var response = _smsSender.Send(smsRequest);
if (response.Code != "OK")
{
throw new BusinessException(response.Message);
}
}
}
public class EmailCaptchaSender: IEmailCaptchaSender
{
public virtual Task<bool> SendAsync(Captcha captcha)
{
//todo 发送验证码
}
}2.4 调用示例
在AppService中，注入ICaptchaManager即可使用
public class CaptchaAppService : ApplicationService
{
private readonly IdentityUserManager _userManager;
private readonly ICaptchaManager _captchaManager;
public CaptchaAppService(IdentityUserManager userManager,
ICaptchaManager captchaManager)
{
_userManager = userManager;
_captchaManager = captchaManager;
}
/// <summary>
/// 获取验证码
/// </summary>
/// <param name="phoneNumber">手机号</param>
/// <param name="type">类型：(登录:login/修改密码: changePassword/找回密码：retrievePassword)</param>
[AllowAnonymous]
public async Task GetAsync(string phoneNumber, string type)
{
await _captchaManager.SendAsync(type, phoneNumber);
}
public async Task VerifyAsync(string phoneNumber, string type)
{
await _captchaManager.VerifyAsync("login", phoneNumber, captcha);
}
}
