PHP人脸识别小程序接口(阿里云OpenAPI)
越信鸥
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-sdk GitHub - 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
-
<?php AlibabaCloud::accessKeyClient('foo', 'bar') // ->regionId('cn-hangzhou') ->asDefaultClient();
添加人脸#

}
}人脸检索，返回的是一个score，我判断小于0.5即不是一个人#
