百度AI开放平台 PHP SDK composer安装

百度AI sdk 文档地址https://ai.baidu.com/ai-doc/FACE/zk37c1qrv 使用教程和百度的文档一样,把原本的引入方式(require_once 'AipFace.php') 改成composer的命名空间(use baidu\ai\AipFace)引入

composer 安装: composer require zkl/baidu-ai-php

使用示例(人脸对比):

    use baidu\ai\AipFace;
    use app\common\model\FaceContrastModel;
    use think\facade\Config;

    class BaiduAiFaceService
    {
        private static $config = [];

        public function __construct()
        {
            self::$config = Config::get('baidu.ai');
        }

        /**

         * @param string $image1 通常为手机、相机拍摄的人像图片

         */
        public static function getFaceContrast(string $image1, string $image2): float
        {
            $image1 = './storage/upload/my/live.jpg';
            $image2 = './storage/upload/my/card.jpg';
            $client = new AipFace(self::$config['app_id'], self::$config['api_key'], self::$config['secret_key']);
            $result = $client->match(array(

            // $result = json_decode($result,true);
            if ($result['error_code'] == 0) {
                $score = round($result['result']['score'], 2);
                //插入记录
                FaceContrastModel::insert(['live_image' => $result['result']['face_list']['0']['face_token'], 'card_image' => $result['result']['face_list']['1']['face_token'], 'sorce' => $score]);
            } else {
                $score = 0;
            }
            return $score;
