    public static function upload_goods_img($whereName="", $width="", $height="")
    {

        // 打开图片的相对路径
        $imgpath = config("img_path");
        // 绝对路径
        $imgRootPath = config("imgRootPath");
        $storeId = "自定义";
        $merchantId = "自定义";
        $old_filename = $storeId . $merchantId . time();
        $filename = $storeId . $merchantId . time() . mt_rand(1000, 9999);
        $type = Goods::upload($whereName, $old_filename);
        if($type) 
        {
            $savepath = $imgRootPath . "/" . $whereName . "/" . $filename . "." . $type;
            $thumbfile = $filename . "." . $type;
            $thumbName = $imgpath  . "/" . $whereName . "/" . $thumbfile;

            $image = 	hinkImage::open($imgpath . "/". $whereName ."/" . $old_filename . "." . $type);
            $image->thumb($width, $height, 	hinkImage::THUMB_FIXED)->save($thumbName);

            $data = [
                "access_url" => $imgRootPath . "/" . $whereName . "/" . $filename . "." . $type,
                "filename" => $thumbfile,
            ];

            return $data;
