后台代码

    function upload() {
        
        $files = request()->file('files');

        // 移动到框架应用根目录/public/uploads/ 目录下
        if($files){
             $item  = [];
            foreach($files as $k => $file){
                $info = $file->move(ROOT_PATH . 'public' . DS . 'uploads');
                if($info){
                    $item[$k]['getSaveName'] = $info->getSaveName();
                }else{
                    $this->error($file->getError());
                }    
            }           
           
           exit(json_encode($item));
        }
