腾讯云短信接口服务
做个小程序需要发送验证码,短信接口是腾讯云的。了解官方的sdk和demo发现对于我这种浅层次的人来说太麻烦了,然后就从网上找了一版
开发准备
1. 申请 SDK AppID 以及 App Key:
在开始本教程之前,您需要先获取 SDK AppID 和 App Key,如您尚未申请,请到 短信控制台 中添加应用。应用添加成功后您将获得 SDK AppID 以及 App Key。
注意:
SDK AppID 是以 14xxxxx 开头。
2. 申请签名:
下发短信必须携带签名,您可以在短信 控制台 中申请短信签名
3. 申请模板:
下发短信内容必须经过审核,您可以在短信控制台中申请短信模板
完成以上三项便可开始代码开发。

需要的依赖
<dependency> <groupId>com.qcloud</groupId> <artifactId>qcloud-java-sdk</artifactId> <version>2.0.1</version> </dependency>
当然你也需要去腾讯云注册APPID和appkey,选择所需要的模板,单发或者群发,我的是单发指定模板的。
