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-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

• regionId('cn-hangzhou')            ->asDefaultClient();

添加人脸#

列出人脸数据#

    function ListGroup(){        try {            $result = AlibabaCloud::rpc()            ->product('FaceAPI')            ->version('2018-12-03')            ->action('ListGroup')            ->method('POST')            ->host('face.cn-shanghai.aliyuncs.com')            ->regionId('cn-shanghai')            ->setAcceptFormat('json')            ->request();                        $result = $result->toArray();            if(!empty($result['Success']) && $result['Success'] === true){                $message = [                    'status'=>'success',                    'message'=>'获取分组成功.',                    'data'=>$result['Data'],        ];            }else{                $message = $result;            }           return $this->response->create($message, 'json')->code('200');        } catch (ClientException $exception) {            print_r($exception->getErrorMessage());        } catch (ServerException $exception) {            print_r($exception->getErrorMessage());        }    }

人脸检索，返回的是一个score，我判断小于0.5即不是一个人#
