上传单张图片，以上传一个商品封面为例

html页面代码

<!DOCTYPE html>
<html lang="zh-CN">
<head>
    <meta charset="utf-8">
</head>
<body>
    <form method="post" enctype="multipart/form-data">
        <p><input type="file" name="cover" /></p>
        <p><input type="submit" value="上传" /></p>
    </form>
</body>

PHP代码

class GoodsModel extends Model
{
    public function publishGoods()
    {
        $data = array();
        $goods_id = $this->insert($data);
        //上传封面图
        $file = $this->uploadGoodsCover($goods_id);
        print_r($file);
    }
    protected function uploadGoodsCover($goods_id)
    {
        $upload = new UploadFiles();
        $four_path = Helper::getFourPath($goods_id); // 000/00/10/09/
        $relative_path = 'goods/cover/' . $four_path; // goods/cover/000/00/01/00/
        $file_dir = Loader::getFilePath('static::' . $relative_path);
        $ret = $upload->upload('cover', $file_dir);
        if (!$ret) {
            return false;
        }
        $file = $upload->getSuccessInfo()[0];
        return $file;
    }
}
(new GoodsModel())->publishGoods();

输出数据如下：
