以下為上傳到百度雲後臺

	private function face_group(){
		//組名
		$groupname = 'pingjiao';

		$client = $this->init_face();
		$ret = $client->getGroupList();
		if($ret['eror_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;
		}
	}
 

上傳照片時檢查人臉可靠性等判斷

		if($ret['error_code']==0){//有人臉
			$result = $ret['result'];
			$face_num = $result['face_num'];

			if(1 == $face_num){//人臉數量為1
				$face_probability = $result['face_list'][0]['face_probability'];
				if(1 == $face_probability){ //可靠性為1
					// $guid = myguid();
					$group = $this->face_group();

					$faces = $client->addUser($image,'BASE64',$group);
					// echo '人臉檢測完成，並已入庫';
					if($faces['error_code']>0){
						$client->addUser($image,'BASE6',$group,$no);
					
					}else{
						// die('可靠性為：'. $face_probability);
						$client -> updateUser($image,'BASE64',$group,$no);
					}
					return true;
				}else{
					// die('人臉數量大於1');
					die('圖片數量僅為：' . $face_probability . ',上傳失敗！');
				}
			}
