PHP人脸识别小程序接口(阿里云OpenAPI)

这两天接的小程序用了阿里云的openapi--人脸识别接口，讲下大体流程和代码

先进入人脸识别文档，开通该服务然后建立RAM子账号，并设置accessKey，并记下两个参数使用阿里云新版php-sdkGitHub - aliyun/openapi-sdk-php: Alibaba Cloud SDK for PHP，用composer安装

composer require alibabacloud/sdk

我用的框架tp5 获取调用该接口的权限

<?phpAlibabaCloud::accessKeyClient('foo', 'bar')// ->regionId('cn-hangzhou')->asDefaultClient();

人脸检索，返回的是一个score，我判断小于0.5即不是一个人#
