篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了阿里巴巴人脸识别接口--phpsdk相关的知识,希望对你有一定的参考价值。

这两天接的小程序用了阿里云的openapi--人脸识别接口,对接口这种工作人人都会,不过还是讲下大体流程和代码以备不时之需

composer require alibabacloud/sdk

然后开始码,我用的框架tp5.0

  • 获取调用该接口的权限
<?php
AlibabaCloud::accessKeyClient(‘foo‘, ‘bar‘) // ->regionId(‘cn-hangzhou‘) ->asDefaultClient();
  • 根据文档写方法

添加人脸
