PHP强制下载远程文件 [英] PHP Force Download of Remote File

问题描述

我有一大堆存储在我的Amazon S3存储上的视频。我正在创建一个非常类似于的PHP脚本，用户可以将视频下载到他们的硬盘。

我想使用这样的东西：

  ;？php 
 $ file_name = $ _GET ['file']; 
 $ file_url ='http://www.myamazons3.com/'。 $ FILE_NAME; 
 header（'Content-Type：application / octet-stream'）; 
 header（Content-Transfer-Encoding：Binary）; 
 header（Content-disposition：attachment; filename = \$ file_name。\）; 
 readfile（$ file_url）; 
退出; 
  

但是，我的印象是这会增加带宽，因为视频将通过我的服务器

有什么想法可以强制下载这些视频，同时避免首先通过我自己的服务器阅读？

非常感谢！

解决方案

查看S3 API文档，并记下您可以设置的标题值。当请求文件时，亚马逊将发送这些文件： http：// docs。 aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html （可以使用POST发送相同的参数来更新现有对象）

I have a bunch of videos stored on my Amazon S3 storage. I'm working on creating a PHP script, very similar to the one here, where users can download the videos to their hard drive.

I'd like to use something like this:

<?php
$file_name = $_GET['file'];
$file_url = 'http://www.myamazons3.com/' . $file_name;
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary"); 
header("Content-disposition: attachment; filename=\"".$file_name."\""); 
readfile($file_url);
exit;

However, I am under the impression that this increases the bandwidth because the video will be coming through my server.

Any ideas on how I might be able to force the download of these videos, while avoiding reading it first through my own server?

Many thanks!

解决方案

Take a look at the S3 API Docs, and note the header values that you can set. Amazon will send these when the file is requested: http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html (the same parameters can be sent with a POST to update an existing object)
