利用阿里大鱼接口发短信，Delphi版

　　阿里大鱼是阿里通信旗下产品，融合了三大运营商的通信能力，提供包括短信、语音、流量直充、私密专线、店铺手机号等个性化服务。每条四分五，价钱还算公道，经老农测试，响应速度非常快，基本上是秒到。官方文档提供了JAVA、.NET、PHP、Python、C/C++、NodeJS 等语言的 Demo，唯独没有 Dephi，但这也不能怪马云，毕竟 Delphi 实在太小众了。

　　最近用 Delphi 写个 App，注册用户需要用到手机短信验证，于是找到的阿里大于，使用 Delphi 10.1 berlin 写了个简单的 Demo 并测试通过，现在交出代码：

有不少同学还在使用D7，不知道怎么用，稍微改改就可以了。
