1、使用自己的支付宝登录阿里云https://www.aliyun.com/，购买免费的短信服务。

搜索“短信”找到图中的【三网合一】进入

点击立即购买，你也可以买有费用的，我测试用就免费申请的（每个用户只能申请一次免费的）。

点击“立即开通”

支付成功后，点击“管理控制台”，可以看到自己的短信服务

2、再次进入购买界面，查看短信接口的定义以及调用方式。

本次案例是发送短信验证码，短信信息也是如此，换下接口和参数即可。

3、编写代码

需要pom引入一下http工具

       <!--httpclient-->
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>

4、测试

运行main方法，查看控制台信息如下

在查看自己的手机收到的短信
