阿里巴巴人脸识别接口--phpsdk

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

• 先进入人脸识别文档，开通该服务 https://help.aliyun.com/document_detail/53378.html?spm=a2c4g.11186623.6.542.5b841f16upd9vN
• 然后建立RAM子账号，并设置accessKey，并记下两个参数
• 使用阿里云新版php-sdk https://github.com/aliyun/openapi-sdk-php，用composer安装

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
