创建一个thinkphp3的框架，创建一个小程序。
在tp3框架里创建公共文件，function.php，生成guid
//生成guidfunction guid(){if(function_exists('com_create_guid')){return com_create_guid();}else{mt_srand((double)microtime()*10000);$charid = strtoupper(md5(uniqid(rand(),true)));$hyphen = chr(45);$uuid = chr(123) .substr($charid,0,8).$hyphen .substr($charid,8,4).$hyphen .substr($charid,12,4).$hyphen .substr($charid,16,4).$hyphen .substr($charid,20,12) .chr(125);return $uuid;}}//生成变种guidfunction myguid(){$guid = guid();$guid = trim($guid,'{}');$guid = str_replace('-', '_', $guid);return $guid;}然后创建indexcontroller.class.php
初始化人脸识别
//初始化人脸识别private function init_face(){ $APP_ID='*****'; $API_KEY='*****'; $SECRET_KEY='****'; $dir=APP_PATH . '/face_sdk/'; require_once $dir . 'AipFace.php'; return new AipFace($APP_ID,$API_KEY,$SECRET_KEY);}public function index($no,$name,$sex,$age){$data['no']=$no;$data['name']=$name;$data['sex']=$sex;$data['age']=$age;$data['guid'] = myguid();$id=M('student')->add($data);if($id){return $this->ajaxReturn(array('error'=>false,'msg'=>'添加成功！','guid'=>$student['guid']));}else{return $this->ajaxReturn(array('error'=>true,'msg'=>'添加出错'));}}获取小组
private function face_group(){ //组名 $groupname='1002'; $client=$this->init_face(); $ret=$client->getGroupList(); if($ret['error_code']==0){ $grouplist=$ret['result']['group_id_list']; if(in_array($groupname, $grouplist)){ return $groupname; }else{ $ret = $client->groupAdd($groupname); if($ret['error_code']==0){ return $groupname; }else{ return false; } } }else{ return false; } }删除小组
//删除组 private function del_facegroup(){ $client = $this->init_face(); $ret = $client->groupDelete('1001'); print_r($ret); }人脸识别
//人脸识别public function facevalid(){$file = './Uploads/1.jpg';if(!file_exists($file)){die('文件不存在');}$image = base64_encode(file_get_contents($file));//如果有可选参数$options =array();$options["max_face_num"]=2;$client=$this->init_face();$ret=$client->detect($image,'BASE64',$options);print_r($ret);if($ret['error_code']==0){//有人脸$result=$ret['result'];$face_num=$result['face_num'];if(1 == $face_num){//人脸数量为1$face_probability = $result['face_list'][0]['face_probability'];if(1 == $face_probability){//可靠性为1$guid=myguid();$group=$this->face_group();$client->addUser($image,'BASE64',$group,$guid);echo "人脸检测完成，已入库";}else{die('可靠性为：' . $face_probability);}}else{die('人脸数量大于1');}}else{die('没有人脸');} }上传文件
public function upload($id=''){if(empty($id)){return false;}$no = M("student")->where("id={$id}")->getField("no");$dir = "./Uploads/studentface";//上传文件路径if(!file_exists($dir)){mkdir($dir,0777,true);}$upload = new ThinkUpload();// 实例化上传类$upload->maxSize = 2048000 ;// 设置附件上传大小$upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型$upload->rootPath = $dir; // 设置附件上传根目录$upload->savePath = ''; // 设置附件上传（子）目录$upload->saveName = $no;$upload->replace = true;$upload->autoSub = false;// 上传文件$info = $upload->uploadOne($_FILES['file']);if(!$info) {// 上传错误提示错误信息echo json_encode(array('error'=>true,'msg'=>$upload->getError()),JSON_UNESCAPED_UNICODE);}else{// 上传成功$file = $dir . $info['savePath'].$info['savename'];$image = base64_encode(file_get_contents($file));$this->facevalid($no,$image);$m=M('head');$data = $m->where("no='{$no}'")->find();if($data){//有数据，更新$m->where("no='{$no}'")->save(array('base64'=>$image,'path'=>$file));}else{//无数据，添加$m->add(array('no'=>$no,'base64'=>$image,'path'=>$file));}echo "采集照片成功";}}小程序首页
