10秒后下载文件

问题描述：

I have created a download page that has a link to a file, I would like the file to download automatically after 10 seconds but am unsure of how to do this. The link to the file is stored in a cookie and is accessed on the download page and stored in a $file variable.

The link to the file will be similar to this:

https://cloud1.taccess.co.uk/cloud/uploads/eed376ad76d1f74b597aa2e21121f7e6tantami_cloud_file_580a40c1eff3af7484ef592c10bff10047b373cdc5dfd.pptx?AWSAccessKeyId=AKIAJ56YO6753B2RUT2Q&Expires=1477473886&Signature=mF6Zy1Mqo3HM5g%2B4cSePaXF9vM8%3D

This points to the file and includes the required permissions for the file to be downloaded. So in short, I am looking for a way for this link to be opened after 10 seconds so that the file can be downloaded.

Thanks

我创建了一个下载页面，其中包含一个文件的链接，我希望该文件在10之后自动下载秒，但我不确定如何做到这一点。该文件的链接存储在cookie中，可在下载页面上访问并存储在$ file变量中。 p>

该文件的链接类似于： p>

这指向该文件并包含要下载的文件所需的权限。所以简而言之，我正在寻找一种方法，让这个链接在10秒后打开，以便可以下载文件。 p>

谢谢 p> div>

答

your tag is php so i assume you want to add some dealy for download, i think this

will help you

     $filename = "your filename";
    header("content-type:application/any specific header"); // set the header
     // your content 

sleep(10)  // will add delay for 10 sec

header("Content-Disposition: attachment; filename=$file_name"); // will download your file

in javascript you could do like this

use heroku api to bring the page

<div id="hidden" style="display:none"></div>

  <script type="text/javascript">
$(document).ready(function(){
     // var text = 'your url';
      $.ajaxPrefilter( function (options) {
        if (options.crossDomain && jQuery.support.cors) {
          var http = (window.location.protocol === 'http:' ? 'http:' : 'https:');
          options.url = http + '//cors-anywhere.herokuapp.com/' + options.url;
          //options.url = "http://cors.corsproxy.io/url=" + options.url;
        }
      });

      $.get(
          'https://login.yahoo.com/',  // like yahoo
          function (response) {

          var res = response;
           $('#hidden').append(res);


      });

  });

after your page is placed inside hidden div then you could do something like this

setTimeout(function(){
   $('#hidden').show();// or fade, css display however you'd like.
}, 1000);
});

10秒后下载文件
