我自认为不想做curd程序员，但是免不了的会对数据基本原子操作进行处理，项目开发过程中的增删改查少不了的，但是又不甘心于curd下去，所以想要在掌握现有知识的基础上，甚至逼迫自己去学习一些东西，去接触新的技术，足够的深度做不到，最起码广度要有所保证，每天进步一点点。 开篇写的算是自己的程序员生涯的一丢丢想法，言归正传，本篇介绍如何对接阿里云新版SDK。
首先开通阿里云人脸服务:
人脸人体-阿里云视觉智能开放平台
点击开通之后就能在控制台看到下图
点击人脸人体以后就会看到下图的具体服务列表，下面所有的服务都会有对应的文档以及在线调试方式。唯一一个要注意的就是上传人脸图片的时候目前只支持上海的Region。
具体可以参考一下文档:使用阿里云视觉智能开放平台时访问域名设置_视觉智能开放平台-阿里云帮助中心
还一个坑就是老版SDK与新版SDK的区别:
老版SDK不支持非上海节点OSS图片地址
新版SDK支持非上海节点OSS图片地址，甚至本地的文件都支持。
老版本文档地址:视觉智能开放平台老版本JavaSDK（不推荐）_视觉智能开放平台-阿里云帮助中心
新版本文档地址:
视觉智能开放平台JavaSDK_视觉智能开放平台-阿里云帮助中心
接下来就直接上代码咯!
