//前台代码
function vdl(){
            $(function(){
                //获取图片路径
                var download_link=$("#img").attr('src');
                console.log(download_link)
                if(download_link == "" || download_link == "undefined"){
                    return;
                }
                setTimeout(function () {
                    //带上图片路径请求方法
                   window.location.href="/element/deo?img="+download_link;
                }, 8000);
                var text = $('.text')
                var times = $('.time')
                count_down(8, times, text)
            });
//后台代码
//调用方法即可  $_GET['img'];需要下载的图片   也可以传参
 public function download(){
        $url=$_GET['img'];
        $filename = basename($url);
        $headers = get_headers($url, 1);
        $fileSize = $headers['Content-Length'];
        header('Content-Type: application/octet-stream');
        header('Accept-Ranges:bytes');
        header('Content-Length: ' . $fileSize);
        header('Content-Disposition: attachment; filename="' . $filename . '"');
        readfile($url);
        exit;
    }
