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
添加人脸

删除人脸
参考地址: https://api.aliyun.com/#/?product=face&version=2018-12-03&api=DeleteFace&tab=DEMO&lang=PHP
/** * DeleteFace, 从人脸库中删除人脸 * * @param string $Group 删除人脸所在的分组 * @param string $Person 删除人脸的姓名 * @param string $Image 删除的人脸编号 */ public function DeleteFace($Group, $Person, $Image){ try { $result = AlibabaCloud::rpc() ->product('FaceAPI') ->version('2018-12-03') ->action('DeleteFace') ->method('POST') ->host('face.cn-shanghai.aliyuncs.com') ->regionId('cn-shanghai') ->setAcceptFormat('json') ->setQueryParameters('Group', $Group) ->setQueryParameters('Person', $Person) ->setQueryParameters('Image', $Image) ->request(); /** * {"RequestId":"8C1F5719-DDD6-433D-A9D0-20B91C0BF048","Data":"ok","Success":true} */ $result = $result->toArray(); if(!empty($result['Success']) && $result['Success'] === true){ $message = [ 'status'=>'success', 'message'=>'删除人物肖像图成功.' ]; }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()); } }
列出人脸数据
参考地址: https://api.aliyun.com/#/?product=face&version=2018-12-03&api=ListFace&tab=DEMO&lang=PHP

列举人脸组
参考地址: https://api.aliyun.com/#/?product=face&version=2018-12-03&api=ListGroup&tab=DEMO&lang=PHP

人脸检索，返回的是一个score，我判断小于0.5即不是一个人
参考地址: https://api.aliyun.com/#/?product=face&version=2018-12-03&api=RecognizeFace&tab=DEMO&lang=PHP
