如何在C# WebAPI项目中使用【手机短信】发送验证码？（用于登录/注册等验证操作）

博主是调用第三方【棒子云】短信接口进行发送验证码的，然后也可以调用别的，方法都是大同小异的。

 

1.棒子云官网：http://smsow.zhenzikj.com/

 

2进行【注册】操作

 

3.在官网点击【个人登陆】进行操作。登录后可以看到自己的后台，自己可以设置短信模板什么的。系统会默认送你【10次】发送验证码的机会。然后就需要买了，最低充值10元，10元能发270条短信，大概就是0.03元一条咯，感觉也不是很贵~

 

4.点击【详情】可以获取应用的AppId、AppSecret，在调用的时候要用到的。

 

可以在官网自行看API文档，下载SDK源码

 

然后正式开始吧~~

5.新建一个程序就不用我说了吧，Windows窗体应用程序/ASP.NET Web应用程序都行，博主新建的是一个WebApi程序。。然后新建一个Class类，用来封装发送验证码的。可在官网SDK下载Coty。博主给出源码，注意修改命名空间。

        {
            return true; //总是接受
        }


    }
}

 

6.然后新建一个控制器【TestController】，在这个控制器中调用刚刚封装的【TaoTaoClient.cs】类，调用方法发送验证码。（注意：博主这里写的是API）

 

7.博主使用【postman】调用接口进行测试。可以看出是发送成功的~
