PHP：下载不在iPad上运行的文件脚本 [英] PHP: Download file script not working on iPad

问题描述

我有一个我编写的文件下载脚本，它从public_html下面读取文件，并允许用户在检查用户是否已登录后下载它们，并且该文件是一个有效的文件供他们下载。

I have a file download script that I have written, which reads files from below public_html and allows the user to download them after checking to see if the user is logged in and that the file is a valid file for them to download.

我最近遇到的一个问题是，在点击链接时，它在iPad上无法执行任何操作。

An issue I've recently come across is that on an iPad it just fails to do anything when the link is clicked.

完成所有检查后的示例下载文件代码：

Example download file code after all the checks have been done:

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/msword");
header("Content-Disposition: attachment; filename=\"file.doc\";" );
header("Content-Length: 50688");

readfile(SITE_PATH .'/files/file.doc');

此脚本已在多个浏览器的PC，Mac和Linux计算机上进行测试和检查（FF，Opera ，IE6-9，Chrome，Safari）似乎工作得很好，所以它必须是iPad不同的东西。

This script has been tested and checked on PC, Mac and Linux machines in multiple browsers (FF, Opera, IE6-9, Chrome, Safari) and all seem to work fine, so it must be something that the iPad does differently.

我想它是可以做的事情iPad实际上没有文件结构来下载文件，但我不确定。

I'd imagine it's something to do with the iPad not actually having a file structure as such to download files to, but I'm not certain.

有没有人遇到过这个问题？如果有，是否有修复？

Has anyone come across this problem before? If so, is there a fix?

推荐答案

iOS Safari不支持文件下载..

iOS Safari does not support file download..

更新：但如果您打算在iPad上打开.doc文件，那么是..您可以这样做...

Update: But if you are looking to open the .doc files on iPad then yes.. you can do that...

使用以下 -

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/msword");


readfile('file.doc');

您的代码与我的唯一区别是我删除了附件标题
只需删除这些标题 -

the only difference in your code and mine is I removed the header for attachment Just remove these header -

header("Content-Disposition: attachment; filename=\"file.doc\";" );
header("Content-Length: 50688");

实际上如果操作系统是iOS，你可以检查客户端操作系统然后不添加下载头像这样 -

Actually you can check for client operating system if operating system is iOS then don't add header for download like this -

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/msword");

if (!Operating_System_Is_IOS)
{

     header("Content-Disposition: attachment; filename=\"file.doc\";" );
     header("Content-Length: 50688");

}

readfile(SITE_PATH .'/files/file.doc');
